    Hello, I've seem some videos where 70-72 A-Body owners have 275-315 tires in the front as well as the rear.

    Aside from proper tire width/backspacing, how do these people fit such big tires in the front?

    My guess is they do some kind of inner fender modification, but will the frame need to be modified or altered in any way?

    Any input is greatly appreciated. Thank you!

    275 40 17 in front fits, just have to remove the 1 bolt at the top of the inner fender . not much room to any bigger. In the rear 315 35 17 fits pretty easily , I rolled the fender lip a bit .

    Really? I know a member on here whos running 265/45/18 on the front without any modification. His tire is about 27.2 inches tall and yours is a little uner 26 inches.
    Were you getting rub on the top bolt of the inner fender?

    yes it would rub a little on the bolt , you could just use a flush allen bolt or something . Also car was dropped about 2 inches .
