My plate says 6PK-F - 1070. It also has 7:00x20 tires and wheels.These tires and wheels seem to just clear the front fenders. It seems that other trucks sit higher of the ground than this truck.Also one odd question ,why would one backing plate in the rear sit inside the wheel and the other is outside the wheel edge. I have not taken off the wheels but they seem the same on each side? thanks Reddog46
