Rim diameter
The rim diameter 4 ( ୴ page 277) is the
diameter of the bead seat, not the
diameter of the rim edge. Rim diameter is
indicated in inches (in).
Tire load rating
The tire load rating 5 ( ୴ page 277) is a
numerical code associated with the
maximum load a tire can support.
For example, a load rating of 91 corre-
sponds to a maximum load of 1356 lb
(615 kg) the tire is designed to support.
See also “Maximum tire load”
(
୴ page 282) where the maximum load as-
sociated with the load index is indicated in
kilograms and lb.
For additional information on tire load
rating, see “Load identification”
(
୴ page 280).
Warning!
G
The tire load rating must always be at least
half of the GAWR ( ୴ page 287) of your
vehicle. Otherwise tire failure may be the re-
sult which may cause an accident and/or
serious injury to you or others.
Always replace rims and tires with the same
designation, manufacturer and type as
shown on the original part.
Warning!
G
Do not overload the tires by exceeding the
specified load limit or vehicle capacity
weight as indicated on the Tire and Loading
Information placard located on the driver’s
door B-pillar. Overloading the tires can over-
heat them, possibly causing a blowout.
Overloading the tires can also result in han-
dling or steering problems, or brake failure.
i Tire load rating 5 ( ୴ page 277) and tire
speed rating 6 ( ୴ page 277) are also referred
to as “service description”.
