I have 205 70 15s  7 in wide all the way around. Tight in the back . Front seems ok.

I've got 225/50/16's on mine (no skirts) - you could probably go to 235's on the back with exactly the right backspace, and still have some clearance to prevent rubbing.

Hoosier is right about the careful mesurements - and you need to be a bit conservative about side clearances. Due to the sidesway of the leaf spring arrangement (and assuming no add-on "track bar") - you can get contact even though things look fine sitting in the driveway.

If you are running the skirts, bout the only thing that fits is the original wheel/tire combination.

I have 14/5.5 in wheels with Coker wide whites (basically oem section width and height) from a Crown Vic on the front of mine. These just barely clear the "A" arms.I cannot put these on the back and put the skirts on.

Summit (and probably others) sell a measuring devise that you bolt to your drum, adjust the arms accordingly as you roll it around your wheel opening, and check tire clearances.  Probably much better than trying various wheels and offsets.

Anybody have any thoughts, guesses, experience with the largest tire size I could fit on 16" wheels to fit in the rear wells of my `57 bird without tubbing it?  I'm a fan of tire patch, so the wider the better. 

I dont know the offset of these AR Torq Thrust wheels I inherited, but mounted they appear standard compared to stock.

I'm prepared for some trial n error, but recommendations would be appreciated.

Cheers... Brian
