Thanks for that Alan.  I have noticed the gearing is really short.    Going up to 295 is quite a 
jump from stock.  I am wondering about the stock 8" wheel width being wide enough for a 
295?    No fender rub at limits?    I don't have the Z0K so I'm not too worried I'd have a 
problem.

The specs on Tirerack are recommending a 9.5" minimum.   Does it look like it's bulging out !  
I am guessing it's a trade off.   How's the turn-in with this setup?
