Well I race at the same track. I run the same tires that almost every other guys runs there. My LHS owner races at the same track and always has his trailer stock with parts for sale, including 1/8th scale buggy and truggy tires and wheels. If I really need a tire change, I will do it on the fly at the track. It's weird but I can justify on the fly purchases with my wife easier than planned purchases. haha.
