swapped mine on thursday and didnt really notice any gain in mpg or performance. well actually, it felt more like pre-35s. i didnt really get used to the way the 3 performed with 35s (without pcmforless, cauze i put the tires on 2 days before that) so im basically comparing the results to before i got the 35s put on. Im happy with it, no gain no loss.
