I've got a set of 6 used Silverstone gravel tires for sale. They're oldish soft compound, in decent shape as far as the tread goes. The rubber has hardened a bit and two have small cracks in the inner sidewall. Not enough that I'd worry about for rallycross, but I wouldn't put them through the punishment of stage rallying. The beads on all of them are excellent, not chewed up by crummy tire machines. They'll mount no problem. One is mounted on a Subaru Forester steel rim, which I'm throwing in as I've got no use for it. They're 195/65-15 size equivalent, pretty much perfect for a lower powered 4wd car or 2wd running 15". I used to use them on my Leggy Turbo and my Impreza before I did the drivetrain swap.

I'm asking $150 OBO for the set of 6. Make me an offer I can't refuse, they're taking up space on my tire rack!
