Knowing your wheel size can save you a lot of time when you are looking to purchase a new set of tires. First, find out your vehicle’s original tire size, which can be found in the owner’s manual or on the tire label. The tire label can be located on the driver’s door jamb, glove box, or inside the fuel hatch. If you can’t locate it, examine the tire’s sidewall.

The tire width is a three-digit number, given in millimeters. The aspect ratio is the ratio of tire height to tire width. The letter “R” refers to the radial construction of the tire’s carcass plies, which runs from lip to lip and provides strength, flexibility, stability and comfort to the tires. Also locate the wheel’s diameter and the load index, which is how much weight the tire is certified to carry when fully inflated. Never buy a tire that has a lower load index than the vehicle’s original tire.
A tire’s speed rating tells you the tire’s top speed at which it can operate. Speed ratings range from Q (the lowest speed) to Z (the highest speed), with an additional H rating that is between U and V. Replacement tires should have speed ratings equal or higher than the original tires.
Different Types of Tires
In addition to knowing what size tire you need, you should also be aware of the different types of tires. Here are a few of the most popular varieties of wheels:
-Touring tires are ideal if you desire a smooth and quiet ride that allows for performance handling.
-High-performance tires are ideal for sports cars, which allow for excellent handling and performance at higher speeds. A softer rubber compound provides increased grip, especially when cornering at high speeds.
-Light truck tires are great for pick-up trucks because they provide durability and traction in off-road situations. SUV tires are designed for on-road and comfortable SUV driving situations.
-Commercial light truck tires are designed for commercial trucks and allow for everyday wear and tear.
