originally i wanted 245/40/18 up front but i'm soo glad i got 265/35/18.. even with the 265's there no rim protection.. Looks better as well.. I did 275/35/18 for the rear because its the stock tire diameter.. 275/40/18 will throw off your speedometer. 285/35/18 is close but taller than the stock diamter.

how bad will it throw it off..... and can the speedcal adjust that?

speedcal can adjust for 275/40/18's.. but why do that.. bigger tire is heavier, takes more power for the wheel to spin.. and its the same width as 275/35/18 which needs no speedcal adjustment. Just curious why

thats what 275/35 looks like on an 18x9.. more sidewall from a 275/40 will just make the rim look smaller

only reason i asked was because a guy is selling his pretty cheap so i thought maybe i could save a few bucks that route... but i wanna do it right

dang, your tire sizes are whack.

265/35/18's for the fronts and 295/35/18's for the rear..
