Is there a difference in backspacing between Wrangler and XJ ecco rims? I believe the Wrangler ones have less backspacing but I'm not sure. I would like to get 33 x 11.50's on my stock rims but I think I will need less backspacing. If the Wrangler ones have less, I'll get a set of those and it will still have a stock rim look. Also, are stock rims wide enough?
