For the 87-88 Thunderbirds?
With a pretty serious fender rolling, and the shorter 86 control arms, I got 315/30/18 Hoosier A6's on the front and rear on 18x10's. I had 295/35/17's on the front of a 88 bird with stock suspension on 17x9's and fender rolling.
As for the rear, I have gotten 325-50-15's in the stock fender well with a rolled lip.
Quad shocks removed.
Wheels:
15 x 10 with 6.5 backspacing.
tires 325-50-15 BFG drag radials.
Stock width T-Bird axles.

Man that's mean
How do you like the 18x10s with the 315's on the front? I've got an 80 Mustang with 18x10's on the front, and 18x12's with 345-30-18 tires. I was thinking seriously about changing over to the 315's on the front when I wear out the current tires.
Oh, and I should mention that its a full widebody kit, thus the ease of fitting huge wheel/tires.
