Its not just tires. Everything has gotten more expensive. It doesn't seem that long ago that I heard some dollar figures it takes just to roll a sprint car off the trailer and race for a night without problems. Those figures were 2-3 thousand per night. Now I hear figures of 7 thousand plus to compete per night. I don't dig the hoosier monopoly but I don't own a car either so its up to the people that have skin in the game to decide what is right for them. Personally I don't see how a blue collar Joe can do it anymore.
