No issues at all with the tire width on the wheel. No issues mounting them, driving them, etc. I attained 575hp out of the 3.2 by getting rid of the 3.2 and replacing it with a 5.4 There is a build thread on that in the engine/transmission section. My point was that they put up with the power - not that they can't be spun, but under normal driving they are really great.
