Reading this forum, it doesn't sound like too many folks use 18 x 7.5 wheels w/ 215/40-18 tires. The first thing I've found wrong is the offset. The new wheels have a +45 mm offset. The car isn't lowered, and it never will be as long as I own it. So will a rubbing problem exist? If I go down to 17 x 7 wheels, the offset goes to +40 mm and that sucks. I will not use spacers.
