Ok getting some rx8 wheels set up. They are 18x8 +50 offset. I am on Cobb springs. Debating between 235/40 and 245/40 tires. Only reason I am really considering the larger 245 size is because they are basically the same price in this larger size...and I figured why not? But I don't want to rub and have to roll the fenders. It's kind of hard to search and get a definite answer on this... as I'm sure a few guys may post they are good with 18x8.5 +40 setup....then later that month they go over a bump with 2 guys in the back and rub. Also, there's tons of different suspension setups. Luckily the cobb springs are not very low in the back.
Anyways, anyone help me out with this?
