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 8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code where it was manufactured, the next two are the tire size code and the last four numbers represent the week and year the tire was built. For example, the numbers 317 mean the 31st week of 1997. After 2000 the numbers go to four digits. For example, 2501 means the 25th week of 2001. The numbers in between are marketing codes used at the manufacturer's discretion. This information helps a tire manufacturer identify a tire for safety recall purposes. 9. Tire Ply Composition and Material Used: Indicates the number of plies indicates or the number of layers of rubbercoated fabric in the tire tread and sidewall. Tire manufacturers also must indicate the ply materials in the tire and the sidewall, which include steel, nylon, polyester, and others. 10. Maximum Load: Indicates the maximum load in pounds and kilograms that can be carried by the tire. Refer to the vehicle's tire information placard or the safety certification label, located on the B-Pillar or the driver's door or on the inside of the fuel filler door on Canadian models, for the correct tire pressure for your vehicle.

The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):

: 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.
