I went from 15x8 AR steelies to 15x8 MT Classic II's with the same set of BFG MT 32" tires on both rim sets.
the Classic II's were cheaper from Summitracing.com than anyone else had the eagle wheels. they made a slight difference in throtte response and a huge difference in handling. I think it had a bigger effect on my ride/handling becuase I have a solid axle truck.
