My buddy has a set of 18's that he had on his maxima.. i doubt that they would fit, but can anyone tell me for sure? I think they'd be too wide.. maybe even too high as well. I have 205/40/17's on it now.

it really depends on the width of the rim and offset. I have 18 x 8 with a 38mm offset and 225/40/18 tires. I have about 1/2" of clearence behind the tire and the outside of the tire is right on the edge of the fender. It actually hits the fender if i hit a hard bump. Im lowered on 2" Sprint springs and tokico blues. It sounds like they are gonna be a tight fit. a 245 tire is about 1 1/4" wider than a 225. Mount em up and give it a try...

If he'll let you try it, it can't hurt. I'd never buy them though w/o it b/c I'd say 99% chance, they won't fit. w/ 225/40/18's mine rubbed w/ ~2" drop. 245/45/18's are almost an inch wider and close to 2 inches taller. They'll rub for sure (in a corner). I'd bet they'll stick out somewhat too.

Are you sure that they are 245/45-18? Most maxima guys run a 245/40-18.

yeah.. i'm sure they're 45's. I set it next to the wheels I have on now and it seems like they're gonna be too tall.. and probably too wide too. Does anyone out there know anybody in western PA lookin for a good cheap set of 18's? He only wants $500 for them and they have brand new performance tires on them. I dont really need them i'm happy with my 17's but i just thought i'd help him out if i could.

yeah they wouldnt fit anyway they would stick out and look stupid..

I dunno how much of a difference there is between 245\40's and 245\45's but I have 245\40's on the back and they don't stick out at all, and my coilovers are bottomed out.

well there would be no difference in the width (245)... but what do you have on the front?

I have 225/40's on the front.
