The sidewall provides valuable information about the tire including the specifications, the brand, and the type of construction. All numbers are standardized and recognized by tire manufacturers around the world.


1. Section Width(mm)

2. Aspect Ratio(Section height as a percentage of the section width).

3. Rim Diameter(in)

4. Load Index

5. Speed Rating

Load Index and Speed Rating

Load index corresponds to the load capacity while speed rating is designated using letters from J to Z and represents the maximum speed of the tire. These two factors are interdependent. Please refer to the tables below for the load index and speed rating.




Ensure maximum performance and a long life from your tires by checking the air pressures at least once a month and set them to the vehicle manufacturer’s recommended pressure(s) listed on the vehicle’s tire placard or in your owner’s manual. Always check and adjust your air pressure when your tires are cold, preferably first thing in the morning before driving. Never release air pressure from tires when they are hot. Wait until the tires cool down and recheck, adding air or releasing as required.


It’s a known fact that regular tire rotation extends the life of your tires and improves performance. Tires are rotated to achieve a uniform wear for all tires. Each tire performs different tasks, therefore tires wear at different rates.

It’s important to rotate your tires according to the correct tire-rotation pattern. Doing so will prolong the life of your tires and will reduce the risk of sudden tire failure. Front tires encounter different tasks than the rear tires. And a front-wheel-drive car’s tires perform different tasks than those on a rear-wheel-drive car. See the Maintenance Schedule section in your Owner’s Manual for additional information about your specific vehicle.

Tire Rotation Patterns



Proper wheel alignment is key to prolonging the life of your tires. If your vehicle is misaligned, it can cause your tires to wear unevenly, and you may experience handling problems such as pulling or abnormal vibration.

Tires and wheels are aligned and balanced at the factory to provide the longest life and best overall performance. Adjustments to wheel alignment and tire balancing are not necessary on a regular basis. Consider a wheel alignment check if there is unusual tire wear or the vehicle is significantly pulling to one side or the other.

A tire that is out of balance often affects ride quality and can shorten the life of tires, bearings, shocks, and other suspension components. If the vehicle is vibrating when driving on a smooth road, the tires and wheels may need to be rebalanced.


Timely replacement of tire is critical for driver safety and also influences vehicle lifespan and performance.

Tips for Tire Replacement

It is the best to replace two tires on one axle at the same time.

Only replacement of one tire of two on the same axle usually causes to unbalance the vehicle.
