91 grand am rims?

i have a 91 grand am that has 17" right now, but i was wondering if i could possibly fit 18's on it. it is the stock height and i would even raise it a little if that would help. i was just wondering if 18 would be to big or not? thank you

i don't see why not - you'd just need different tires but other then that I'd think everything would be alright specially if you "raised it a little"
