Depends on the tire, Tri-ace and bfg you can get 2 races on the rear tires.Tri-ace holds up better than the bfg. Tensor your going to need to change tires every time you take fuel, 4 on the rear per race. I have run both Tri-ace and bfg. I prefer tri-ace. I got on the racer program for tensor, but after seeing how well they hold up. I couldn't afford to run tensor. Fronts you could run the season on 2 sets.
