EXAMPLE:
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 un-
der 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
