Ray Carton 440 Block Radial Slicks

We were determined to fit the 30x9 radial slicks within the wheelwells. The 28x9 slicks had no clearance issues since they were mounted on 15x7-inch rims with 4-inch backspacing. The 15x8 1/2-inch rims have 4 1/2-inch backspacing. We carefully hammered to stretch the inner wheelhouse back 1/2 inch. After the "tweaking," we went for a ride to make sure there was no tire rubbing. There was enough clearance, as seen here at the front of the wheel opening. These 30.0/9.0 slicks (PN 18210) have an actual diameter of 29.5 inches and a tread width of nearly 10 inches. T indicates the circumference, also known as the rollout of the tire. C07 is the rubber compound of the tire, which is a little softer than the D05 of the 28-inch slicks. View Related Article
