When buying tires, it’s essential to use the proper size & type of tire to ensure your safety and the safety of others on the road. Many factors can determine which tires are suitable for your vehicle, including width, height, rim diameter, load index, and speed rating.

The best place to start is with your vehicle’s Tire Information Placard, which can be found on the driver-side door jamb. This will tell you the tire size and other important information for your car or truck. On a new vehicle, it is usually located in the glove box or inside the fuel door.

How to Read a Tire Size on a Tire’s Sidewall?

Tire Size can be seen in different ways. The way to read it is similar no matter what position the tire is in on your vehicle. It will always have a series of numbers followed by letters.

The first number is the tire’s width from sidewall edge to sidewall edge.

The second number is the aspect ratio of the tire’s height compared to its width. For instance, 50 means this tire will be 50% as tall as it is wide.

The letter at the end designates what type of tire it is.

A-All Season

C-On/Off-Highway Commuter

D-Performance Tire

E-High Performance Tire

J-Special Trailer and Camper Tread Design

The numbers that appear after the letter refer to the tire’s construction, dimensions, and load capacity. These numbers are often referred to as “Ply Rating.”

  1. Tire size does not include the tire’s rim size, its diameter in inches, or millimeters. The rim size determines both the overall tire height and width.

Where to Find Your Tire Size

  1. In addition to your car’s door placard, the tire size is on the outside of each tire.
  2. The Tire Information Placard can be found in a few places depending on the vehicle:
  3. a) Inside the glove box or in the fuel door compartment (if equipped).
  4. b) On top of or behind many dash panels.
  5. c) Inside the trunk lid.
