I plan on purchasing aftermarket wheels in spring. They will most likely be 18x8.5 with a 42mm Off set. My question is, what size of tires would be most suitable for my car so I do not have to worry about rubbing issues and I want to sit flush with my fenders. I've heard that 240-245/40-45/18 is a good range. I have a 4th Gen, dropped on Eibach Springs with Kyb GR-2 shocks. Eibach's droprate I believe is 1.5 Front/ 1.3 Rears.

I've heard good things about Toyo Proxes 4's and Kuhmo ASX tires. They are both reasonably priced and perform well. Any opinions? I will be using my stock wheels and tires for the winter and aftermarket wheels/tires for the summer.

Also do I need to purchase Hubcentric rings for aftermarket wheels? Are spacers necessary for a 42mm offset on a 4th gen?

Thanks for your help in advance.

 

Probably 235/45. Try the tire forum for better help.
