Best Tires For Ford Super Duty: Complete Guide

8 Best Tires For Ford Super Duty

In the late 20th century, Ford realized that they needed to add something to their popular line of trucks that could stand up to the demands of the modern workforce. Requiring a heavier duty option than the world-famous F-150, Ford released the Super Duty in 1999.

Over the years, there have been four generations of the Super Duty, each bringing in new facelifts, performance capabilities, and models. But no matter which generation Super Duty you have, the tires will always end up needing to be replaced.

One aspect of Super Duty tires that helps to narrow down your search is that they need to be “LT” rated or be Load Range E (3,415-pound capacity each) to stand up to the truck’s demands. That said, there are still hundreds of different options to sift through. But that’s where we come in.

Using this guide, you’ll quickly learn about the best tires available today for your Super Duty. No matter if you’re a road-warrior, do a little off-roading, or you need all-out mud-terrain tires, we’ve got you covered!

Let’s get right into it and help you find the best Super Duty tires out there. Here are the 8 best options on the market:

Michelin Defender LTX M/S — Best All-Season

{{tire-info-with-links="/tire/michelin-defender-ltx-m-s"}}

Any Ford Super Duty owners that are in the market for an all-season tire need to look no further than the top-rated Michelin Defender LTX M/S.

The entire Defender line of tires from Michelin is widely accepted as the premier tire for all vehicle types, and heavy-duty trucks are no exception to that rule. Offering all of the common sizes that come on Ford Super Duty trucks, the Defender LTX M/S is a no-brainer for anyone looking to put some miles on their Super Duty.

With Michelin’s top-notch EverTread rubber compound, the Defender LTX M/S is able to last up to 10% longer than other comparable tires on the road today. This enables it to provide a comfortable ride throughout all 70,000 miles of the tread life warranty, regardless of the time of year or weather conditions.

The Defender LTX M/S is also built using Michelin’s MaxTouch Construction process, which reduces road noise and vibrations to maximize the comfort of the tire. You won’t have a better driving experience in your Ford Super Duty than you’ll get from the Defender LTX M/S.

Specifications

Some specifications may vary based on the exact tire size selected.

• Warranty: 70,000 miles
• Max Load Capacity: 3,415 lbs
• Max Inflation Pressure: 80 psi
• Tread Depth: 13.5/32”
• Tire Weight: 48 lbs
• UTQG Treadwear: N/A
• UTQG Traction: N/A
• UTQG Temperature: N/A
• All-season highway tire that’s built to last and perform in all weather conditions
• MaxTouch Construction offers reliable traction and even treadwear

FAQ

What’s the mileage warranty?

The Michelin Defender LTX M/S comes with an industry-leading 70,000-mile tread life warranty. Thanks to the Evertread technology, many Super Duty owners have been able to get 80,000 miles or more out of these tires over the years.

Can I drive on this tire year-round?

Absolutely! The Defender LTX M/S is our favorite all-season truck tire for many reasons, one of them being the year-round reliability. The “M/S” rating on this tire means that it’s certified for use in both mud and snow, hinting at its ability to offer traction in any condition.

Is this better than the OEM Michelin A/T2 tires?

The OEM Michelin A/T2 tires are great tires in their own rights, but we rank the Michelin Defender LTX M/S a bit higher for overall performance, though it is a highway tire. If you want to stick with an all-terrain, we suggest replacing the worn-out OEM Michelins with one of our all-terrain suggestions below.  

Cooper Discoverer HT3 — Best Highway

{{tire-info-with-links="/tire/cooper-discoverer-ht3"}}

If we didn’t already have the Michelin Defender LTX M/S as our top-rated all-season tire, it would be here as the best highway tire. But not far behind is the Cooper Discoverer HT3, a tire designed specifically for use on heavy-duty pickups or commercial vehicles.

The Discoverer HT3 is another all-season tire, capable of providing reliable traction all year long. With its 50,000-mile tread life warranty, the Cooper Discoverer HT3 outlasts many other tires on the road, allowing Super Duty drivers to really put some miles on them before they need to be replaced.

Circumferential grooves around the tire work in conjunction with 3D Micro-Gauge sipes to channel water away from the center of the tire. This enables the Discoverer HT3 to provide consistent traction in all road conditions, including wet and even light snow.

Enhanced tread block stability and continuous shoulder ribs help to promote even wear across the entire tire while simultaneously improving the steering response of your Super Duty. It’s a great all-season highway tire that you’ll be happy to have on your truck.

Specifications

Some specifications may vary based on the exact tire size selected.

• Warranty: 50,000 miles
• Max Load Capacity: 3,415 lbs
• Max Inflation Pressure: 80 psi
• Tread Depth: 14.5/32”
• Tire Weight: 49 lbs
• UTQG Treadwear: N/A
• UTQG Traction: N/A
• UTQG Temperature: N/A
• Designed to provide occupants with a quiet and comfortable ride throughout their life
• Continuous shoulder ribs resist uneven tire wear

FAQ

Is the Cooper an all-season tire?

Yes, the Cooper Discoverer HT3 is an all-season highway tire, and it’s actually our second favorite overall all-season tire behind the Michelin Defender LTX above. The Discoverer HT3 provides reliable traction year-round.

How does this compare to the Michelin Defender LTX?

The Cooper Discoverer HT3 is a high-quality all-season highway tire that puts more of a focus on comfort than longevity, which is the main difference between the two tires. The Michelin Defender LTX comes with a 70,000-mile warranty, compared to the HT3’s 50,000-mile warranty.

Can I drive on this tire off-road?

While the Discoverer HT3 can certainly handle occasional off-road use to get to a job site or to drive down a dirt road, we don’t recommend going off-roading with this tire. It’s designed more for the highway and comfort, and you’d be better off with an all-terrain tire in that case.

Bridgestone Blizzak LT — Best Winter

{{tire-info-with-links="/tire/bridgestone-blizzak-lt"}}

Many drivers of the Ford Super Duty don’t think that a winter tire is necessary. With 4-wheel drive, a heavy vehicle, and a high-quality all-season or all-terrain tire, you don’t need a dedicated winter tire, right?

Not exactly. While the above combination will be fine for most scenarios and in light snow, severe snow and ice will stop your Super Duty in its tracks without a winter tire. That’s where the Bridgestone Blizzak LT tire comes in.

Designed as the best winter tire on the market for heavy-duty trucks, the Blizzak LT will enable you to drive through just about any severe winter weather condition. With biting edges all over the tread and proprietary winter technologies, the Blizzak LT provides winter traction that is unmatched by anything else on the road today.

Offered in all major heavy-duty truck tire sizes, the Bridgestone Blizzak LT tire is hands-down the best tire on the market for your Super Duty’s winter tire needs. Put a set of these on your truck and snow and ice will be no problem next winter!

Specifications

Some specifications may vary based on the exact tire size selected.

• Warranty: None
• Max Load Capacity: 3,415 lbs
• Max Inflation Pressure: 80 psi
• Tread Depth: 17/32”
• Tire Weight: 47 lbs
• UTQG Treadwear: N/A
• UTQG Traction: N/A
• UTQG Temperature: N/A
• Winter tire designed specifically for trucks that need a Load Range E tire even in the winter
• 3-Peak Mountain Snowflake rating ensures that these tires meet the strictest industry standards for winter performance

FAQ

How many winters will this tire last?

As long as you don’t drive on them outside of winter and you store them properly when they are not in use, you can expect to get around 3-4 winters out of them at the very least. Some people get 5 or more seasons out of the Blizzak LT tires, it just depends on how often you use them.

Why is the Blizzak the best winter tire for my Super Duty?

The Blizzak line of winter tires from Bridgestone has become the industry standard over the years. So when Bridgestone decided to release the Blizzak LT — a winter tire designed specifically for trucks and vans — it immediately rose to the top as the best option on the market.

Do I need to add studs to these tires?

No, the Bridgestone Blizzak LT is a completely studless winter tire! Gone are the days of having to manually add metal studs to your winter tires, modern tire technologies allow for uncompromised winter performance without the use of metal studs.

Cooper Discoverer AT3 LT — Best All-Terrain

{{tire-info-with-links="/tire/cooper-discoverer-at3-lt"}}

You might’ve heard of the standard Cooper Discoverer AT3 or AT3 4S, but those were designed for light-duty trucks that don’t require Load Range E tires. For the Ford Super Duty — and other heavy-duty trucks — Cooper stepped it up a notch and now offers the Cooper Discoverer AT3 LT.

Designed to be the best on- and off-road tire for heavy-duty trucks, the Discoverer AT3 LT can be used in any circumstances. With a 60,000-mile tread life warranty, you can expect to get even more life out of them than Cooper’s highway-terrain tire above, while also having the ability to take them off-road.

Using Cooper’s Even Wear Arc and Durable-Tread Technologies, the Discoverer AT3 LT will last longer than its competitors while also ensuring even contact with the road surface at all times, enhancing control and handling.

The Discoverer AT3 LT uses stone-ejector edges to dispel small rocks and stones away from the tread to prevent puncture, while Cooper’s Whisper Grooves reduce road noise and vibrations. This makes it one of the most comfortable all-terrain tires on the market for your Ford Super Duty.

Specifications

Some specifications may vary based on the exact tire size selected.

• Warranty: 60,000 miles
• Max Load Capacity: 3,415 lbs
• Max Inflation Pressure: 80 psi
• Tread Depth: 16/32”
• Tire Weight: 53 lbs
• UTQG Treadwear: N/A
• UTQG Traction: N/A
• UTQG Temperature: N/A
• The popular Cooper AT3 tire, enhanced for use on heavy vehicles such as the Super Duty
• Even Wear Arc Technology improves handling while resisting uneven tread wear

FAQ

Can I use this tire on- and off-road?

Absolutely! The Cooper AT3 LT is one of the best all-terrain tires on the market, capable of offering Super Duty drivers the ability to do typical highway driving or off-road adventuring as they please. The rugged durability and tough tread compound can stand up to off-road abuse.

What’s the mileage warranty?

The Cooper AT3 LT comes with a 60,000-mile tread life warranty. This is great for any truck tire, but when you’re looking at a Load Range E all-terrain tire, a 60,000-mile warranty is about as good as you’re going to find anywhere on the market.

What sizes are offered?

Designed specifically for use as the premier heavy-duty all-terrain truck tire, the Cooper AT3 LT is offered in sizes ranging from 16” wheel diameters up through 18”. Keep in mind, all sizes that the AT3 LT comes in will always be an “LT” size. This includes the common Super Duty size of LT275/65R18.

BFGoodrich T/A KO2 — All-Terrain Honorable Mention

{{tire-info-with-links="/tire/bfgoodrich-all-terrain-t-a-ko2"}}

Don’t take the “honorable mention” ranking to heart, as we could have just as easily referred to it as an alternative instead, because the BFGoodrich T/A KO2 is a top-of-the-line all-terrain tire that’s a great choice for the Ford Super Duty.

With a 50,000-mile tread life warranty (recently upgraded from 40,000 miles), the T/A KO2 is designed to provide exceptional on-road and highway performance. But it really shines above other all-terrain tires when it’s taken off-road for some additional use and abuse.

The BFG T/A KO2 uses a special sidewall construction that’s twice as thick as the original KO tire to prevent damage and punctures. At the same time, BFG’s special Serrated Shoulder design offers unparalleled off-road grip in dirt, mud, and other loose types of terrain.

That same shoulder design also makes the BFG T/A KO2 stand out for its aggressive looks, which makes it one of the most popular tires on the market for Ford Super Duty trucks. If you want to instantly change the look of your Super Duty for the better, start by adding a set of KO2’s for it.

Specifications

Some specifications may vary based on the exact tire size selected.

• Warranty: 50,000 miles
• Max Load Capacity: 3,415 lbs
• Max Inflation Pressure: 80 psi
• Tread Depth: 15/32”
• Tire Weight: 55 lbs
• UTQG Treadwear: N/A
• UTQG Traction: N/A
• UTQG Temperature: N/A
• Best off-road performance in the all-terrain truck tire category
• Serrated Shoulder Design digs through snow, dirt, and mud for optimal traction

FAQ

How aggressive is this tire?

As far as all-terrain tires go, the BFGoodrich T/A KO2 has one of the most aggressive tread designs on the market. Don’t let that deter you though, they handle perfectly fine on the roads. The aggressive design is one of the biggest selling points, as the T/A KO2 is one of the best looking tires out there and can instantly transform the look of your Super Duty.

Can I use the KO2 on-road?

Yes, without a doubt! The BFGoodrich T/A KO2 is an all-terrain tire, meaning that it can be driven on normal roads as well as for off-road driving. Don’t let the aggressive tread design fool you, it’s a great tire for normal highway driving as well.

How long will these tires last?

The BFG T/A KO2 comes with a 50,000-mile tread life warranty from the factory, so you can expect to get at least that much out of them if they’re well-maintained. They used to only come with a 40,000-mile warranty, but BFG has upped it in recent years to reflect their true performance.

BFGoodrich T/A KM3 — Best Mud-Terrain

{{tire-info-with-links="/tire/bfgoodrich-mud-terrain-t-a-km3"}}

If this name seems eerily familiar, that’s because it’s part of the same popular line of T/A tires by BFGoodrich. But this time we have the best mud-terrain tire on the market for the Ford Super Duty — the BFGoodrich T/A KM3.

As the third iteration of the T/A KM series of mud-terrain tires, the relatively new KM3 is the best tire on the market for off-road performance on the Super Duty (and any other truck it fits). As BFG’s off-road Maximum Traction Tire, the T/A KM3 was designed to do exactly that — provide better off-road traction than any other tire on the market.

Using BG’s Krawl-Tek rubber compound, the T/A KM3 is able to provide reliable traction, grip, and control on all surfaces, on- and off-road. The sidewall is even stronger than that of the KO2, with the Traction-Armor Sidewall Sculpture preventing punctures during off-road driving.

The BFGoodrich T/A KM3 mud-terrain comes in all major truck tire sizes from 15” through 20” wheel diameters, making it an easy choice for the Ford Super Duty drivers wanting to go off-road.

Specifications

Some specifications may vary based on the exact tire size selected.

• Warranty: None
• Max Load Capacity: 3,415 lbs
• Max Inflation Pressure: 80 psi
• Tread Depth: 18/32”
• Tire Weight: 65 lbs
• UTQG Treadwear: N/A
• UTQG Traction: N/A
• UTQG Temperature: N/A
• BFGoodrich’s Maximum Traction tire, offering unparalleled off-road performance
• Able to grip rocks and loose terrain from all directions thanks to large tread blocks

FAQ

Can I drive this on the highway?

Although it’s called a “mud-terrain” tire and it has a super-aggressive look to it, you can absolutely drive the BFG T/A KM3 tire on the highway. They don’t last as long as other types of tires, nor are they as quiet. But they’ll do just fine!

How loud is this tire?

As you might imagine, these mud-terrain tires with the big tread blocks and deep tread depth are not going to be as quiet as normal tires, or even most all-terrains. That said, the KM3 is perfectly capable of handling regular, on-road driving without being too loud to make your driving experience a bad one.

What’s the mileage warranty?

Like pretty much all mud-terrain tires on the market, the BFG KM3 does not come with any sort of mileage warranty. Designed to be driven in rugged, off-road conditions, BFGoodrich can’t offer a mileage warranty. But if driven just on the highway, you can expect to get around 30,000 to 40,000 miles out of a set.

CORSA All-Terrain — Best Temporary Spare

{{tire-info-with-links="/tire/corsa-all-terrain"}}

For a good-quality tire that will get your Super Duty back on the road without an issue, you should consider going with the CORSA All-Terrain tire.

As a tire that’s relatively affordable, reliable, and versatile, the CORSA All-Terrain is the perfect option for a temporary spare. With a spare tire, you don’t want to spend too much money or have to worry about whether or not it can handle the terrain you’re in, which makes having an affordable all-terrain tire underneath your truck the best way to go.

With all-season traction capabilities, the CORSA All-Terrain is able to provide Super Duty owners with predictable and reliable traction no matter when they have another tire go down and need to use a spare. And with stone-ejectors built into the tread design, you won’t have to worry about your spare tire failing on your way to the shop.

For its price, you can’t beat the CORSA All-Terrain when it comes to a temporary spare tire for your Super Duty.

Specifications

Some specifications may vary based on the exact tire size selected.

• Warranty: 40,000 miles
• Max Load Capacity: 3,415 lbs
• Max Inflation Pressure: 80 psi
• Tread Depth: 17/32”
• Tire Weight: 49 lbs
• UTQG Treadwear: N/A
• UTQG Traction: N/A
• UTQG Temperature: N/A
• Capable of highway driving and handling rugged off-road conditions
• An affordable all-terrain option that makes it the perfect Super Duty spare tire

FAQ

Why is this a good spare tire for my Super Duty?

When it comes to the perfect spare tire for your Super Duty you want three things — affordability, reliability, and versatility. That’s exactly what the CORSA All-Terrain provides. It’s the most affordable tire in this guide, it comes with a 40,000-mile warranty, and as an all-terrain, it’s versatile enough for any conditions.

Why should I get an all-terrain as my spare tire?

As the name suggests, all-terrain tires are great for any type of terrain, namely normal streets and off-road conditions. This means that no matter what the other three tires on your truck are, the CORSA All-Terrain can handle itself and any type of driving you need to do while you’re getting the original tire fixed.

Should my spare tire match the rest of the tires on my truck?

In an ideal world, you would want your spare tire to match the rest of the tires on your truck. You’d also rotate it in along with the regular tires to promote even wear. But most people don’t do that, and it’s not really necessary. You want the spare to be the same size more than you really need them to be the same tire.

Michelin LTX A/T2 — OEM Tire

{{tire-info-with-links="/tire/michelin-ltx-a-t-2"}}

Many vehicle manufacturers put relatively cheap tires on their vehicles from the factory that meet minimum requirements just to maximize profit. Thankfully for their customers, Ford typically puts a nice OEM tire on. The Super Duty is no exception to this, with the high-quality Michelin LTX A/T2 included as the stock tires.

As a Michelin tire, the LTX A/T2 is about as good as you can get from an OEM tire. With a 60,000-mile tread life warranty and an all-terrain tread design, it can handle just about any conditions right from the factory.

Using a special rubber compound designed specifically for trucks, the Michelin LTX A/T2 was engineered to offer a smooth, quiet ride while simultaneously increasing fuel efficiency and promoting even wear across the tire.

Overall, it’s truly a high-quality tire that you’ll enjoy from the factory. If you want to stick with an all-terrain option when the stock tires wear out, we do recommend the Cooper and BFGoodrich options above, but you could do far worse than another set of Michelin LTX A/T2 tires!

Specifications

Some specifications may vary based on the exact tire size selected.

• Warranty: 60,000 miles
• Max Load Capacity: 3,415 lbs
• Max Inflation Pressure: 80 psi
• Tread Depth: 17/32”
• Tire Weight: 52 lbs
• UTQG Treadwear: N/A
• UTQG Traction: N/A
• UTQG Temperature: N/A
• MaxTouch Construction promotes even tread wear and reliable contact with the road
• Provides a comfortable, low-noise ride as well as enhanced fuel efficiency

FAQ

Is this an all-terrain tire?

Yes, the Michelin LTX A/T2 is an all-terrain tire (that’s what the A/T stands for). This OEM tire enables Super Duty drivers to spend their time driving on the highway for heading off-road for work or fun, it’s a great all-around tire from the factory.

Should I get the same tires as OEM?

You don’t ever have to replace the tires on your Super Duty with the same ones that came on the truck from the factory. While the Michelin LTX A/T2 is a great tire in its own right, we recommend replacing them with one of the other tires suggested in this guide once the original ones wear out.

How long will they last?

The Michelin LTX A/T2 comes with a 60,000-mile tread life warranty. Similar to the Cooper AT3 LT mentioned above,  a 60,000-mile warranty is at the top of its class for a high-quality, Load Range E all-terrain tire. If properly maintained, you can even get upwards of 65,000 miles or more out of these OEM tires.

Ford Super Duty Tire Sizes

The Ford Super Duty comes in all shapes and sizes, from the F-250 up through the F-650, but our focus in this section of the guide will be on the F-250 and F-350 since they are by far the two most popular Super Duty models. Even with all the different models and trims over the years, the Ford Super Duty has had just 5 different OEM tire sizes to keep in mind over the last decade (2011 through 2020):

• LT245/75R17
• LT265/70R17
• LT275/65R18
• LT275/70R18
• LT275/65R20

The Ford Super Duty has been offered in countless models and trim levels over the years, but we’ll focus on the two most popular ones in this table — the F-250 and F-350. Luckily, the tire sizes between the F-250 and F-350 are the same in just about every year’s various trim levels. That said, we have comprised the tire sizes for each model and trim of the Ford Super Duty over the past decade.

The sizes presented here will be accurate for both the F-250 and F-350 (in most cases). So as long as you know the year and model of your truck, simply use the spreadsheet to quickly find out your tire size:

Note: All Super Duty tires are “LT” sizes, but for the sake of more easily reading this table, we’ve included the tires without the “LT” designation.

Ford Super Duty Tire Buyer’s Guide

When Should I Get All-Terrain Tires For My Super Duty?

The discussion between all-terrain and highway-terrain tires has been going on for decades. What’s the better option? At what point of off-road driving should you make the switch to an all-terrain tire? Should you stick with a highway-terrain tire for better road-driving and long tread life warranties? When it comes to the Ford Super Duty, should you get all-terrain tires instead of highway-terrain tires?

We’ll start off with this — the Ford Super Duty comes straight from the factory with all-terrain tires on it in the Michelin LTX A/T2. That said, you don’t have to stick with all-terrain tires if you know you’ll never be doing any off-road driving. But if you ever have to take your Super Duty off-road, for work, for fun, or for both, then we do suggest going with all-terrain tires. They can be used on- and off-road, whereas highway-terrain tires are not designed for both.

That said, highway-terrain tires can certainly be used for an occasional off-road drive on a dirt or gravel road, such as perhaps to visit a job site or something like that. But for consistent off-road driving, we suggest going with an all-terrain. Especially if you get a high-quality all-terrain like the Cooper Discoverer AT3 LT or BFGoodrich T/A KO2, you’ll be able to get back and forth from off-road to the highway with no problems whatsoever in either case.

Are Highway Tires the Best Option For Most Super Duty Drivers?

Even though all-terrain tires give you the ability to go off-road whenever you want, the big question is how many Super Duty drivers are really taking their trucks off-road? If you’re not, you might not need to invest in a set of all-terrain tires. Many Super Duty trucks never drive off-road throughout their entire lives. So are highway-terrain tires really the best option for most Ford Super Duty drivers?

Even with everything said above, the truth is that the vast majority of Ford Super Duty drivers don’t need an all-terrain tire. Most Ford Super Duty trucks are not ever taken off-road, and people just buy them because they’re great trucks and they can haul a lot of weight behind them. And for hauling a trailer down the road, you don’t need an all-terrain tire. So in most cases, highway-terrain tires actually are the best option for Super Duty drivers.

But again as said above, modern-day all-terrain tires can be driven on the roads and highways with no issues whatsoever. The Cooper Discoverer AT3 LT, for example, comes with a 60,000-mile tread life warranty. That’s only 10,000 miles less than our top-rated all-season and actually 10,000 more than our top-rated touring tire. So it really comes down to personal preference, in the end, to decide which type you should buy.

How Long Will My Super Duty’s Tires Last?

With the big tire sizes and heavy-duty load ratings that come on the Ford Super Duty, replacing tires on the truck is not cheap, to say the least. Putting new tires on your Super Duty is one of the most expensive recurring costs that you’ll face. Because no matter how well you take care of them, they will eventually wear out. But once you get a new set of tires on it, how long will they last on your Super Duty?

How long the tires on your Super Duty will last cannot be given as a definitive answer since it depends on so many different things. The biggest thing is the tire itself since the mileage warranty will give you an idea of how long it should last. But it also depends on the condition of your Super Duty and your driving habits as well. For most Super Duty tires on the market, you can expect to get between 50,000 and 70,000 miles out of a decent set of tires.

To get the most life out of your tires, make sure you do everything you can to maintain them as best possible. This means rotating them every 5,000 miles, keeping them balanced, ensuring they’re set at the right air pressure, and keeping your truck aligned. If you do all that regardless of the tires you have on it, you’ll get as much life as you can from them. At that point, it will really boil down to the tire itself — a high-quality tire with a long tread life warranty will outlast a cheap tire with a shorter life expectancy.

How Are F-150 Tires Different From Super Duty Tires?

Some people might just look at an F-150 and a Ford Super Duty and think they’re the same thing. After all, they’re both just Ford trucks, right? Most people don’t know the differences between the two, and that’s perfectly fine! Some of the parts are even the exact same between the two and can be swapped out with no problem. But what about the tires? How are F-150 tires different from Super Duty tires?

Both types of Ford trucks come with 17”, 18”, and 20” wheels and similar corresponding sizes. But that’s about the only similarity between the two. The biggest difference is their maximum load capacity. Ford Super Duty tire sizes are preceded with “LT”, which indicates that they are for trucks and are Load Range E tires. This extra capacity enables the Super Duty to haul what its drivetrain was built to, far exceeding the Ford F-150.

While the load capacities of the tires are quite different, it isn’t the only thing that differentiates the tires between the two types of Ford trucks. These Load Range E tires also require much more air pressure to be used correctly. In most Ford Super Duty trucks, you’ll set the pressure in the rear tires to 80 psi and the front tires to 55 psi. In the F-150, all four tires will typically be set at 35 psi. While you could put Load Range E tires on your F-150, you don’t really need to. And you definitely don’t want to put standard-load tires on your Ford Super Duty!
