Notes on Tires
Tires are normally classified in the format xxx/yy AA zz where:
- xxx is the width of the tire from sidewall to sidewall in millimeters
- yy is the aspect ratio, or the ratio of the sidewall height to the tire’s width
- AA is two things. First is the tire type. This is most often R for radial. The second letter corresponds to the speed rating of the tire. Speed ratings are as follow:
| Q | S | T | U | H | V | W | Y | Z |
| 99 mph | 112 mph | 118 mph | 124 mph | 130 mph | 149 mph | 168 mph | 186 mph | 149+ mph |
- zz is the diameter of the wheel that the tire fits, in inches
- The designation “M+S” following the size information designates a tire designed for extra traction in mud and snow
