Customer Information Tire Information (U.S.A.) GCW GCW (Gross Combination Weight) is the weight of the loaded vehicle (GVW). GCWR (Gross Combination Weight Rating) is the maximum allowable weight of the vehicle - including all cargo and passengers - that the vehicle can handle without risking damage. The GCW must never exceed the GCWR. 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. 9-40
