Alan, the tires both Steve and I choose to run are made by Radir, under license from Mickey Thompson. They are M/T slicks. THey are a very hard rubber compound, and seem to wear like iron, even with the smoky burnouts I do at the track on occasion. They come out of the East Coast, and, at just under $300.00 a piece (!), are pricey. Coker Tire makes the Firestone pie-crust rear tire as well, and not only are they D.O.T. approved, but have thread channels cut in as well. The Hurst "cheater" slicks are re-capped tires, and by far the cheapest. But, they use a Goodyear Wrangler truck radial carcass, then put on their tread. I'd be careful if I were racing with these, but for the street, they'd be awesome!!!
