5x4.75 is the bolt pattern.
I just got a set of stock rims for my '88, and have a set of American Racing Outlaw II's I could probably part with. The fronts are 15x8 and in great condition with BFG Radial T/A's which I believe are P215/65R15's, low miles on the rims and tires. The rears are 15x10's with bald BFG Radial T/A's, P255/60R15's-one is blown out. When it blew out, it chewed the rim up just a little, which is barely noticable. With a tire mounted and aired up, you wouldn't even see the scratches. The rear rims are a little older, and need to be cleaned. I'd let the set go for $200.00.
