I was very happy with a set of Bridgestone RE960 pole positions using stock front and 275-30/19's in the rear. As has been said, the 275's fit fine on the stock rims. The rears end up being 25.6" diameters vs stock 26" which is less than a 2% difference. 3% is cited as the usual allowable tolerance. That's 30 aspect. If you wanted to stay with 35's it would bump the rear diameters up an inch. Given that there's already nearly an inch stagger vs the front diameters with stock sizes I'd have some concerns about increasing that much w/o adjusting the front suspension geometry (plus smaller is effectively producing a slightly lower gear ratio). Ride quality with the 275-30's is actully better than the stock Michelins, and the RE960 has a 40k mile A/S tread.
