20x10 wheels with 4.5 back space, would that work with my airride setup of bags and drop spindles? or is this too wide of a tire up front? thanks jason
guess i should say its a 69 gmc with 6 lugs

I'd do 8 inch wide on the front, just to make it easier, not as hard on the steering. Don't need the extra few inches on the front. Dunno bout backspacing though, sorry.

I know N2billets truck 'Lucy' had 20x8.5's w/5.75" of BS using a stock GM crossmember w/GM 'style' disc brakes & GM 73~87 arms. IMO, a 10" wheel w/4.5" BS is going to hit the front fender arch when compressed (air'd-out or suspension travel). Even the back might be tough & require creative mini-tubbing w/4.5" BS-ing.

Why the need for 10" wheels up front?
Why that specific back-spacing?

Drums or discs up front? Drums, you may be OK, but I doubt it. Discs- they will stick out.

Out back, you will be on the ragged edge of fitting, but I don't think you will clear the outside edge.

I Nathan measured for me an 18x10 up front would not work well, 9in was max and that was still pushing it.
8.5 seems to be the average with 20's
