Did you order the rims with ant offset?The rim width for the JEGS star lights (approx. $140 per wheel) was 8" in the front, and 10" in the rear. I really love the 33" Packard's in the rear. Because all of the tire companies measure their tires differently...I went and measured a bunch of them mounted. The 33 Packard's have a 31" carcass, with 1" paddles...making the entire tire 33" from paddle tip to paddle tip. The 32" SS360's also have a 31" carcass with 1/2" paddles making its outside diameter measure 32". But both these tires have 31" Carcasses, just different size paddles. Having said all of this, I was disappointed in the performance of the front SS360's. The Pro R is a heavy car, and the Packard's have a lot of bite...they can, during aggressive driving, push the ss360's in corners more than I would like. You can feel the ss360's slide sideways during hard cornering. After some research looking for a ribbed traction tire with a 31" Carcass...I picked up a set of 32 GMZ XL TT tires for the front, and absolutely love them. Their Carcass also measures 31 inches. They have the traction that I crave, and make the car corner like it is on rails. The tire width of the Packard's is advertised at 15 inches, but they measure 14 inches wide on my rims. The GMZ's are 12 inches wide. This car is heavy...and needs wide tires for flotation in my opinion.
