Tony, the stocktire size (rear) was 225/50/16, which equates to roughly 24.85 inch diameter and 837 revs per mile. So, I guess this is where we start to make trade offs between traction/gearing/ and transmission regearing...?
Kumho does make 245's with a diameter of 24.3, Toyo's 245's are 24.6...so I could go with a 245mm width rather than a 255 or 265. This would let me get a bit wider than I am today with 225's on the rear.
I'd end up with 225's front and 245's rear.
For a track like summit point, with lots of turns and relatively few opportunities for top gear, is it generally wiser to go for wider tires and more traction or narrower tires with lower profile - assuming a choice has to be made?
I can't afford close ratio gears this summer
