Gonna upgrade to 18s soon, not sure what size would fit without rubbing. Car is riding 1.5" lower than stock. Thinkin 245 45 18s.? Any input or experience would be appreciated. .
How wide are the wheels that you are planning to use? +40 is good for 8" wheels on an MN12, and that width will take a 245/45 tire no problem. If you are looking at 8.5" or 9" wide wheels, they should be around +35 offset.
