Tire Designations - Volvo S40 2005 Owner's Manual

2005 Volvo S40

Tire designations

Federal law mandates that tire manufacturers place standardized information on the sidewall of all tires
(see the illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):
1. 215: the width of the tire (in millimeters) from sidewall edge to sidewall edge. The larger the number,
the wider the tire.
2. 65: The ratio of the tire's height to its width.
3. R: Radial tire.
4. 15: The diameter of the wheel rim (in inches).
5. 95: The tire's load index. In this example, a load index of 95 equals a maximum load of 1521 lbs (690
kg).
6. H: The tire's speed rating, or the maximum speed at which the tire is designed to be driven for
extended periods of time, carrying a permissible load for the vehicle, and with correct inflation pressure.
For example, H indicates a speed rating of 130 mph (210 km/h).
NOTE: This information may not appear on the tire because it is not required by law.
7. M+S or M/S = Mud and Snow, AT = All Terrain, AS = All Season
