What is the back space on your wheels?
I have 275 on a 4.25" back space, with a 7" wheel and plenty of room on the spring and fender.
8.75 stock a body rear.

I just measured from the outer face of the brake drum to the outer edge of the spring. 5-9/16". I'll mount the 245s and decide if they stay or to try 255s
