WARNING
Exceeding GVWR or GAWR Specifications:
Exceeding the GVWR or the GAWR specified on the certification label is dangerous.
Exceeding any vehicle rating limitation could result in a serious accident, injury, or
damage to the vehicle.
Do not use replacement tires with lower load carrying capacities than the originals
because they may lower the vehicle's GVWR and GAWR limitations. Replacement
tires with a higher limit than the originals do not increase the GVWR and GAWR
limitations.
Never exceed the GVWR or the GAWR specified on the certification label.
