right now i have 17x8 +45 front and 17x9 +38 rear wheels, currently i have 235-45 perelli P-zero corsa's that i got used for a good price, i was wondering whats the biggest tires i could fit w/ these off sets, they rears are kinda far out compaired to stock, but i want some more meat all the way around, i'll deff goin w/ atleast a 245 on these rims next time, but would like to run 255's or more also, can anyone let me know what width and offset for 17's that people are using to run 275-40-17's, thanks
