If you run Vintage or historic racing, these are the tires that a lot of racers use. Hoosier TD's. Bob Woodman tires sells them for $202 each new plus shipping. I'll sell the whole set of 6 for $225 plus shipping.
Size as listed above: 24 x 8.5 x 16. They run great on a GT flared 914 on 16x8 rims. I ran them one day in a DE.
shipping is from Charlotte, NC
