Hi everyone, I know this is an old forum, but I could use a little advice on some wheel and tire sizes. I'm just able to afford a good set of wheels for my CR-Z. I bought a set of 18 x 8 (40mm offset) wheels for my car and tires that are 215/45R18. My car is not lowered yet so I would like to know if the tires and wheels that I selected we'll fit without any issues of rubbing. I would really appreciate a reply as soon as possible. Thanks all
Use our wheel offset calculator to visualize the new tire position when changing wheel and tire sizes. Convert wheel offset and backspacing to calculate the correct setup for your vehicle.
Use this website to compare stock to your new setup. It'll give you some info about how close/far the wheel is to the inside, outside, and top of the wheel well. It's up to you to go and check if everything will clear.
I have 225/40 R18 wheels with +35mm offset. they look flush at the rear, with about 10mm sticking out at the front. I recently discovered a shiny spot in the inner passenger-side wheel well. I got the car like that, though, I've never noticed any rubbing.
