my thought train....hybrid with 40 plus mpg i could do heavier wheels and lose a few..i was getting 28-30 with the scion with a supercharger ..so as long as i don't get under 35 with the lexus I'm good...Gotcha. Well, let me know. Weight was a factor for me since this is a hybrid AND my daily driver. But I wanted to go as VIP as possible. LOL.
