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 corre-
sponding 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 condi-
tions, 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
