18x8 +48 or higher should be good yeah
You're alright with a +42 offset because your wheel is only 7.5 wide (probaby sticks out just as much as a 8" with higher offset)
I don't understand this whole offset thing...(uhm)
I'm I okay with 18X7.5 +42 with 225/40/18's?
Thanks! Here's a couple pics of mine
Offset is how much the mating surface of the wheel to the hub is offset from the center of the wheel. Most FWD cars have a positive offset, meaning the hub surface of the wheel is closer to the outside face of the wheel.
