I'm looking at a 91 Z28 for purchase, and it needs tires badly - to save some $$$ I hope to use the tires off my old car.

The 91 is a Z28 with rear disc brakes, stock 16" wheels - the tires and wheels I would like to try to fit on there are 15" rallys from an 87 Camaro. If anyone has any experience with this, please share your experience (This will be my 6th f-body, but only my 2nd 3rd gen)

Ya, not a common task, but when you have $400 worth of tires and your new car needs tires, you'd try it too!

 

According to AndyZ28 (the MAN) yes 15's will fit over the rear discs on Z28's/1LE's/B4C's. I have not tried it myself but I believe what he says.

 

I have the PBR rear disk on mine and I currently run 15" wheels. They will fit but its kinda tight!

 

thank you guys! Looking forward to being able to post about my new 3rd gen soon!
