Thanks for the input. Are you thinking they'd be too narrow functionally or from a looks standpoint? The truck has 8.25 x20's on now and the rh-5's are 6.5 inches wide. The older rims are 6.0 inches wide and I was hoping they would support 8 or 8.25 tires. Also, I was wrong about the studs, they are the same size. Thanks for any feedback, Mark
