Thanks scotia. I was thinking 255's on my '67 falcon, probably a good choice. I have run Hoosier 9x30 slicks in the past, when they are new, they REALLY hook, but the initial ultra hook goes away fairly quickly. They still hook pretty good after that, and once the characteristics of the tire stabilize, they last a long time, but there was a noticable difference after about 10 hits. Shortly after that, we switched them side for side, didnt really change anything. This was a long time ago, so the current tires may be different. Not that they were "bad" tires or anything, just thought it was a notable trait at the time. Also, these were thier stock eliminator tires.
