Tire Markings

1 - U.S. DOT Safety Standards Code (TIN)

2 - Size Designation

3 - Service Description

4 - Maximum Load

5 - Maximum Pressure

6 - Treadwear, Traction and Temperature Grades

NOTE:

  • P (Passenger) - Metric tire sizing is based on U.S.

    design standards. P-Metric tires have the letter "P" molded into the sidewall preceding the size designation.

    Example: P215/65R15 95H.

  • European - Metric tire sizing is based on European design standards. Tires designed to this standard have the tire size molded into the sidewall beginning with the section width. The letter P is absent from this tire size designation. Example: 215/65R15 96H.
  • LT (Light Truck) - Metric tire sizing is based on U.S.

    design standards. The size designation for LT-Metric tires is the same as for P-Metric tires except for the letters "LT" that are molded into the sidewall preceding the size designation. Example: LT235/85R16.

  • Temporary spare tires are designed for temporary emergency use only. Temporary high pressure compact spare tires have the letter "T" or "S" molded into the sidewall preceding the size designation. Example: T145/80D18 103M.
  • High flotation tire sizing is based on U.S. design standards and it begins with the tire diameter molded into the sidewall. Example: 31x10.5 R15 LT.

Tire Sizing Chart

EXAMPLE:

Example Size Designation: P215/65R15XL 95H, 215/65R15 96H, LT235/85R16C, T145/80D18 103M, 31x10.5 R15 LT

P = Passenger car tire size based on U.S. design standards, or

....blank.... = Passenger car tire based on European design standards, or

LT = Light truck tire based on U.S. design standards, or

T or S = Temporary spare tire or

31 = Overall diameter in inches (in)

215, 235, 145 = Section width in millimeters (mm)

65, 85, 80 = Aspect ratio in percent (%) - Ratio of section height to section width of tire, or

10.5 = Section width in inches (in)

R = Construction code

  • R means radial construction, or
  • D means diagonal or bias construction

15, 16, 18 = Rim diameter in inches (in)

Service Description:

95 = Load Index

  • A numerical code associated with the maximum load a tire can carry

H = Speed Symbol

  • A symbol indicating the range of speeds at which a tire can carry a load corresponding to its load index under certain operating conditions
  • The maximum speed corresponding to the speed symbol should only be achieved under specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and posted speed limits)

Load Identification:

Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:

  • XL = Extra load (or reinforced) tire, or
  • LL = Light load tire or
  • C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure

Maximum Load - Maximum load indicates the maximum load this tire is designed to carry

Maximum Pressure - Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire
