Message: I suspected that would be a stumbling point. Traction. You can always find cheap Zrated tires in the buy and sell. Most of them have 75%+ tread and someone is alamost always going to sell them for a 3rd of original cost. Heat up a nice Z rated tire (my favorites are Michelen) and you should bite down hard and shave a half sec off that time.
