Re: Tire Size - 69 Camaro
Wow, L60-15's, I haven't heard of L60's and HiJackers in years, old school, takes me back. I wish I had a good answer to your question, but unfortunately I can only offer some words of caution. I realize it's a bit apples and oranges, but I'm currently running 17x9" with a 5.50" backspacing (with a 275-40 tire on the rear with a 12 bolt and drums) and I had to use a spacer as they rubbed on the inside. Be careful with the backspace, you might want to use 5.25". I know you're planning on a 15" wheel, so like I said, my input doesn't actually match your intended wheel diameter so this may be of limited help. I did run 255-60-15's on 8" ralley wheels in the past with no problem. I seem to recall a post here somewhere indicating that a 275 is pushing your luck, but you'd have to seach the wheel/tire forum for that info. Good luck.
