Post your wheel and tire combos.
I just picked up a set of Mopar rallye wheels with BFG T/A's off a guy with a 70 Cuda for $300. Rims need to be cleaned and repainted but look OK and tires are in excellent shape. I couldn't believe they fit. My 71 Demon has a 73 an up disk conversion up front and 73 up 8 1/4 rear.
Front 14" rallyes with BFG T/A 245/60R14's (no mods other than lifting the front a bit)
Rear 15" rallyes with BFG T/A 275/60R15's (lift kit and air shocks with a 1/4" spacer)
Rears fit good with about 1/4" either side, air shocks only at about 70lbs to not bottom out. Ride is nice and smooth especially since I just rebuilt the front.
I really hated the 14" Cragars that came with the car. They were the ones that had oval holes to fit other cars and I had a hard time lining them up every time I took them off. The chrome had also blistered on the hubs so they didn't look good close up. Cheepo tires on them. Was gonna sand and paint them until I came across this deal.
I do think I might goto a 255/60R15 for the rear when its time. I'll get Cooper Cobras instead of the T/A's. Just like the look better.
