Looking at the tires on a recent purchase (80 z28) and they are dated from 2011 and there are age splits in the tread. I think the car sat garaged for much of the last 7 years. Balancing didn’t help the vibrations at 65mph plus. Current Tires are BF Goodrich Radial T/A: Rear: P255/60R15. 102S M+S Front: P235/60R15. 98S M+S I’m in for buying new tires. Stock rims (body color) and I want to keep them. I would like a little wider rears. I don’t want to go crazy and I want the ride to be good for cruising. Ideas on tire brand/sizing for a second gen Z?
