Will this size wheel cause any problems or annoyances? Will I have a problem with the center caps as I do not want to put spacers on! I am looking for a wheel that has a nice lip, that is 5 spokes, and this is the only wheel i can find with these dimensions. I dont want to push my luck and was wanting to stay at 18x8. Thanks

I have a set. You will be fine, although center cap mounting will depend on the wheel itself.

18x8.5 with a 38mm off-set should use a 235/40/18 tire or smaller.

if you go bigger you might rub in the front on the inner fender well when you turn the wheel all the way. like parking or making a u-turn.

I don't rub on 245 40 18s. Maybe on a 4th gen you would have rubbing issues, but not a 5th?
