WARNING
●Improperly inflated tires can fail
suddenly and cause an accident.
●The Gross Vehicle Weight Rating
(GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight ca-
pacity is indicated on the Tire and
Loading Information label (if so
equipped) . Do not load your ve-
hicle beyond this capacity. Over-
loading your vehicle may result in
reduced tire life, unsafe operat-
ing conditions due to premature
tire failure, or unfavorable han-
dling characteristics and could
also lead to a serious accident.
Loading beyond the specified ca-
pacity may also result in failure of
other vehicle components.●Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure gauge
to ensure that the tire pressures
are at the specified level.
●For additional information re-
garding tires, refer to “Important
