Shop Tires by Size
SEARCH CAR, TRUCK & SUV TIRES BY SIZE
When you’re looking for new tires, you’ll find a wide range of options for all vehicle types at every Tires Plus. You will need your full tire size to get the correct fit for your vehicle, but you can start browsing options when you shop tires by wheel diameter.
Don’t know your tire size? Look for a series of letters and numbers on your tire‘s sidewall, like P225/60R16. The last two numbers, in this example 16, are your vehicle’s wheel diameter.
WHAT'S MY TIRE SIZE?
WHAT DO TIRE SIZES MEAN
Tire size refers to this long string of letters and numbers (ex. P225/70R1691S) you may have seen on the side of your wheel. Each letter and number classify what purpose, limits, and type of vehicle the tire is designed for.
WHERE TO FIND TIRE SIZE
It’s easy to find your tire size when you know where to look. You can refer to your owner’s manual or check your current tires’ sidewalls for the tire code.
HOW TO READ TIRE SIZE
A tire size code covers specifications about how the tire should be used and the tire’s construction. Using P225/70R16 91S as an example tire size, we’ve broken it down so you can learn what the numbers and letters mean on your tire:
TIRE SYMBOLS
| Symbol | Definition |
| P | This means the tire is designed for Passenger Cars. Other common letters seen here include LT (Light Truck), ST (Special Trailer), and T (Temporary, for spare tires). If your vehicle uses Euro-metric or metric tires, this symbol will not be part of your tire size. |
| 225 | This is the Width of the tire. It measures the widest point of the tire (sidewall to sidewall, about halfway down) in millimeters. It does not measure the width of the tread. |
| 70 | This is the Aspect Ratio of the tire. It measures the sidewall height as a percentage of the total width of the tire. |
| R | This means it’s a Radial Tire. The internal design of the tire design has cord plies — which reinforce the tire — arranged at 90 degrees to the direction of travel, or "radially" (from the center of the tire). This is the standard design for almost all automotive tires today. |
| 16 | This is the Wheel Diameter. It measures (in inches) the diameter of the wheel that the tires are designed to fit. |
| 91 | This is the Load Index. It measures the maximum weight a tire can carry, with the majority of passenger vehicles falling somewhere between 75 and 100. |
| S | This is the Speed Rating. A vehicle’s maximum service speed is ranked by class, ranging from lower ratings for most passenger vehicles to higher ratings for performance vehicles. |
