‍Bridgestone TRR Spare Tire

Temporary-use spare wheels, often known as space savers, are created specifically for emergencies. They are often lighter and smaller in size than your car's conventional wheels, allowing them to be conveniently stored until needed without adding extra weight to your vehicle.

In an emergency, spare tires can be quite useful. You can use your spare wheel to get home safely or to reach a repair shop and get the problem fixed professionally. They are a far more practical and helpful alternative to inflator kits or other options such as sealants.

Sealants can take some experience to use and might harm your tires if applied incorrectly. Bridgestone is one of the world's largest tire producers. But does the TRR spare tire live up to the hype?

Bridgestone manufactures high-quality, safe, and long-lasting tires that perform well in a variety of climates and terrains. Its tires offer a comfortable and silent drive while providing excellent fuel efficiency. However, as compared to most other tire manufacturers, its tires have a higher price tag.

The Bridgestone TRR spare tire comes from a long line of quality vehicle tires. So, what does it have to offer you?

Fuel Efficiency

Rolling resistance refers to the amount of work required by a vehicle to maintain a constant speed on the road. As one may assume, the higher the rolling resistance, the more effort is required. This can cause increased fuel usage.

Like the other tires offered by the company, Bridgestone uses NanoPro-Tech in the TRR spare tires to achieve this goal. This technique reduces the rolling resistance of the tire, allowing the vehicle to conserve gas.

Ride Quality

Bridgestone has always put a premium on riding comfort. As a result, no matter the weather or the road conditions, the TRR spare tire from this brand provides a quiet, smooth, and pleasant ride. Its tires use Resonance Noise Attenuated technology, which reduces road noise while also improving ride quality.

Traction and Handling

Every Bridgestone TRR is designed to provide exceptional traction and handling.  This tire provides quick-handling, braking, and acceleration, even at high speeds. On the other side, the winter tires give exceptional traction, grip, and handling stability.

Traction is also affected by differences in tire construction. The radial tire's design allows the sidewall and tread area to act independently from one another. As a result, the tread sits significantly flatter on the ground and has a more uniformly distributed contact patch.

In summary, radial tires offer a larger footprint, stronger tread, and more uniform weight distribution. This results in a more stable and constant contact patch, which improves traction. This typically leads to more consistent tire wear and longer tire life.

Weather Conditions

In hot conditions, tires work well, but they may provide lower grip strength than summer tires. This reduces the steering, braking, and cornering capabilities of your tires. This trade-off is important for spare tires to function well in mild winter conditions while still providing an extended tread life.

Spare tires such as the TTR are a fantastic choice for drivers in mild temperatures since they combine summer and winter performance. The spare tires can provide grip in the winter, but they aren't the ideal choice for driving in snowy weather. During wintertime, drivers who are subjected to severe conditions should probably consider converting to snow tires.

Given their combination of summer and winter performance qualities, the spare tires may be more suited for winter driving than summer tires. However, we recommend switching to winter tires for the best grip and performance in harsh winter conditions.

Larger Rim Diameter

In terms of steering, braking performance, and grip feel, both the 17-inch and 18-inch wheels and tires were in the sweet spot. The extra grip and ride quality are slightly degraded when switching from 17-inches to 18s. Tires with a greater sidewall, such as 18-inch tires, are often more flexible than those with a narrower sidewall.

When driving over bumps and potholes, your tires work as shock absorbers and can give more cushioning. Also, because 18-inch tires are lighter, the engine is not required to work harder to accelerate your vehicle. They might also aid in the reduction of wear on the suspension and braking systems which occurs over time.

Radial Construction

The Bridgestone TRR Spare tire hosts a radial construction. In the tread area, radials are around 80% more resistant to cuts and penetrations. This is due to the structural variations between radial and bias-ply tires.

A radial tire is made up of two pieces. It has a layer of rubber-coated steel wires that arcs from one bead to the next in the casing.

Steel belts made consisting of multiple rubber-coated steel plies are then inserted under the tread to support the crown. These belts are cut and puncture-resistant. If you cut through the fabric on a bias-ply tire, you'd have to cut through a lot of steel balls to get all the way through the tire at the tread region.

When cuts do occur, radial tires are usually easier to patch. When a radial tire is destroyed, just a tiny section of the tire is harmed. On the other hand, when the sidewall of a bias-ply tire is cut, it affects 35 percent of the tire's total structure.

Warranty

All Bridgestone tires come with a variety of warranties that are meant to safeguard the consumer in the event of a failure. This is also true for the TRR.

Like other tire manufacturers, Bridgestone offers guarantees on materials and workmanship, as well as mileage warranties. Bridgestone also promises client satisfaction.

If the tread wears down before the tire reaches a specified number of miles, Bridgestone will replace it with an equal tire free of charge. The tire must wear consistently over the tread, down to the final 2/32-inch of tread, in order to be changed. The coverage will be prorated and will last for the first five years from the date of purchase.

This guarantee only applies to passenger and light vehicle tires. As a result, OEM tires and commercial vehicle tires will not be covered. Warranty coverage ranges from 40,000 to 80,000 miles.

To be covered by this guarantee, tires must be purchased from an authorized dealer and fitted properly.

If the tire is damaged within the first three years after purchase, it will be replaced for free.

Free mounting and balancing will be included in the replacement. The replacement will be done on a prorated basis after the first three years, up to five years. The remaining original tread depth on the tire to be replaced should be greater than 2/32 of an inch.
