The size marking identifies the tire’s dimensions and wheel diameter. The listed sizes use different wheel diameters, so match the replacement tire to the size specified for your vehicle rather than choosing by appearance. The facts do not identify which size applies to a particular trim or engine, or provide load or speed ratings. Confirm those details on the door jamb or in the owner’s manual before buying or fitting tires.
