Hey guys,
About to order some wheels for my 77' stepside. The wheel tubs are stock only mod is 2"drop shackles. Rear is a 9.25. What backspacing and rim width am I looking for to run the Widest tire possible with stock tubs? I am sure this question has been asked to death, I did my diligence surfing through old posts but could not find the one I was looking for..... Thank you in advance

I ran a 15x10 with 4 inch backspacing with P295/50R15 on the rear of my 81 stepside with stock height & stock tubs, tires were 26" tall with 10" tread width.

Thank you, Any pics of the old girl?

Think I can fit a P325/50R15 under her? That equals out to 28 X 13.50R15... I am running a Hoosier pro street that is 28x12.50R15 right now....

sure heres a pic
