Mo, I have 18x7.5 and have no problems with them. If I had a choice of buying wheels again, I wouldn't buy anything bigger than 17" and nothing less than 8" wide. I have my reasons for thinking that way.

That being said, wheels are a personal opinion type deal. Everybody can offer their opinion, but you might only listen to the ones that kinda agree with you.

That wasn't much help, but just thought I should share my opinion :D
