Has anyone tired this??? or know if it will not work...? I was thinking of running 275/60 because of the contact path and height.
Any ideas would be helpful. Thankyou

Stephen, Do you have disc brakes on the rear?
Disc brake cars can run about 1 more in of back spacing tha drum cars. I had 275/50 drag radials on 15X8 draglites with 5in back spacing, They fit but any turns I did they rubbed the inner wheel well. I would have to say for my car 4.75 would the max. I put center line warriors 15x9.5 with 4.5 backspacing. The same drag radials. They fit fine. The tire is the same width as the fender flare. I have a rear picture on my website, If you want to see them.
Later
John
