Tires Sizes: Learn What They Mean

Exclusive summary about Tires Sizes By Adam Lenk

Okay, a typical car tire label reads something like this "P185/75R 14 82S." Shorter or narrower tires have lower numbers.

In lay's terms, this tire's height is 75 percent of its width. Performance tires would have a lower number in this space.

The next letter stands for the tire's type. The next number in the label "82" stand for the tire's load index. The speed ratings are S for up to 112 mph, H for up to 130 mph, V for up to 150 mph, Z for 150 mph+. At high speeds, the tire can get very hot and the tread can separate from the belts.

When selecting tires for your car or motorcycle you should also pay attention to some other tire qualities which may effect your car or motorcycles performance or the durability of your tires. Most of the tire size and speed ratings are the same for car and motorcyle tires but always refer to your owners manual.

Wheel and Tire Sizes For Your Vehicle

Exclusive summary about Wheel and Tires Sizes By Travis K

The following are various high performance wheel and tire measurements that play an important part in determining tire and wheel fitment and sizes:

Wheel Backspace, Wheel Offset, Bolt Circle, Hub-Centricity vs. Lug-Centricity, UTQG (Uniform Tire Quality Grading) labeling system, Calculating Tire Dimensions, Tire's sidewall

Besides correct fitment, width of wheel and tire also influences handling and ride quality. Always choose a rim width within the range of the tire's acceptable rim width specifications. Always be sure that the chosen rim width is within the tire's range of acceptable rim width specifications. Never try to mix mill metric wheels and tires with standard inch wheels and tires. Reading your tire's sidewall is a must anytime tires are mounted on wheels.
