So I need a little information and assistance in understanding all this rim and tire terminology. I am wanting to get a whole new wheel setup when I need new tires. I've been looking at some 18x8.5 and also 18x8.75 rims. I have no idea what this translates to for tires. I am also installing a coilover kit so there may be some rubbing issues? (hopefully not) I've been considering 19s in the same width as well. Any info, advice, or past experiences will help tremendously.
