Wow thats a great deal, nice score. I never liked the idea of siped tires either, but it makes a difference prepped tarmac or dirt. You guys seem to be willing to try just about anything to get a tenth off yout sixty foot times, this seems like a cheap and easy thenth of a second to me. The sipe allows the tire to give a little more, flex and bite into the ground, im not sayin to go and sipe some drag slicks, but for street tires, and straight line starting and stopping siped tires perform better.
