How to read the tire size for your vehicle?

Vlada June 06 2022

When shopping for new tires, you'll need to know the size of your current tires. You can find this information on the sidewall of your tire.

What do the tire numbers represent?

The aspect ratio of a tire is the two-digit number that follows the slash mark. The 65 in a P215/65 R15 tire, for example, indicates that the height is 65% of the width. The bigger the aspect ratio, the larger the tire's sidewall will be.

Here's how to read a tire size

What do the numbers mean on tire size?

The first number in a tire size is the width of the tire in millimeters. The second number is the height, and the third is the diameter or width of the rim that it will fit on.

For example, a common passenger car tire might be listed as 215/60R16. This means that the width of the tire is 215 millimeters, the height is 60% of the width, the tire will fit a wheel with a 16-inch diameter, and it's a radial tire.

If you see P215/65R15, this means the same thing except it's a passenger car tire that's designed to perform well in wet conditions. The "P" stands for "performance."

All-terrain tires are marked with an "A" instead of a "P."

If you see LT215/75R15, this means the tire is designed for light trucks. The "LT" stands for "light truck." The load rating and speed rating will be different for these tires than for passenger car tires.

The load rating is a number that indicates how much weight the tire can safely carry. The speed rating is a letter that indicates the maximum speed the tire can be driven at.

You'll also see a UTQG rating on your tire's sidewall. UTQG stands for Uniform Tire Quality Grading.

How to choose the right tires for your vehicle?

The first thing you need to do is identify your vehicle's tire size. Once you know the size, you can start shopping for tires. When choosing tires, it's important to consider the following:

-Tire type (all-season, winter, performance, etc.)

- Driving conditions

- Vehicle type

- Your driving habits

All-season tires are a good choice for most drivers. They provide good traction in wet and dry conditions and perform well in light snow. If you live in an area with heavy snowfall, however, you'll want to consider winter tires. Winter tires are designed to provide better traction in snow and ice.

Where to Find Your Tire Size

You can find your vehicle's tire size in the owner's manual or on the door placard. The door placard is located on the driver's side doorjamb. This placard lists information about your vehicle, including the tire size.
