Ok here goes I have my mind made up on tires 315/75/16 now what size rim can I put on?? 16x9 16x10 I see talk of offset and tires stop's etc I dont want to get in over my head, too late LOL They will be going on my 97 F-150 xcab 4x4 with a 5" lift.

 

I'd suggest a 16x10 inch wheel with 4 1/2 inches of backspacing, which is what most wheels for our truck have.
