Special Vehicle Notes
When searching by tire size alone, please be aware that the displayed results may not be applicable (or recommended) for your vehicle due to several factors (including but not limited to size, speed rating, load capacity, intended service conditions, etc.).

How to find your size
All the tire size information is located on your tires’ sidewall.

- 255
- 55
- 18
- 97
- T
Width
This three-digit number represents the width of the tyre in millimeters (mm), measured from sidewall to sidewall. Since this measure is affected by the width of the rim, the measurement is done when the tyre is on its intended rim size.
Ratio
This identifies the tire’s aspect ratio, which is the relationship of the tire’s sidewall height to the tire’s width. In this example, the sidewall height of the tire is 55% of its width. The lower the ratio, the smaller the sidewall height, which means better cornering, but a rougher ride.
Diameter
This number (in inches) indicates that the tire is designed to fit on a wheel with an 18-inch diameter.
Load Index
This indicates how much weight the tire is certified to carry at maximum safe inflation. It doesn’t mean 97 pounds, because it’s actually an assigned value that corresponds with its “actual” load capacity found on a load index chart. If you look up 97 on the chart, you’ll find 1,609 pounds.
Speed Index
This indicates the maximum safe speed at which a tire is certified to carry a load under specified conditions. Speed ratings range from A (lowest) to Y (highest), with one exception: H falls between U and V. Exceeding the lawful speed limit is neither recommended or endorsed.

>> The sizes shown are average design values for tires measured on specified measuring rim widths. Some tires may vary from this value by +/-3% of the section height (affecting overall diameter), and +/-4% of the section width.
>> Section width varies approximately 0.2" (5mm) for every 0.5" change in rim width.
>> Tread patterns are often tuned to accomodate different tire widths. Tires for a particular dimension of a given tireline may vary in appearance from the tire shown in the photograph.
WARNING: Serious or fatal injury may result from tire failure due to underinflation or overloading. To ensure correct air pressure and vehicle load, refer to vehicle owner's manual or tire information placard on the vehicle. Serious injury or death may result from explosion of tire/rim assembly due to improper mounting. Only tire professionals should mount tires and they should never inflate beyond 40 psi to seat the beads. Before mixing types of tires in any configuration on any vehicle, be sure to check the vehicle owner's manual for its recommendations.
DANGER: Never mount a 16" diameter tire on a 16.5" rim.
DANGER: Never mount a 17" diameter tire on a 17.5" rim
Inflation pressure increase must not exceed the maximum pressure branded on the tire sidewall. When a customer requests a replacement tire with a lower speed rating than the original equipment tire, you must clearly communicate to him or her that the handling of the vehicle may be different, and that its maximum speed capability is limited to that of the lowest speed-rated tire on the vehicle. Exceeding the lawful speed limit is neither recommended nor endorsed.
