I know its too early to be thinking next year....

If the tires aren't lasting find a better tire. You should be able to run a 100 lap race on a 1/3 mile track with one set. Same goes for Thompson where the race is only 75 laps. Two day shows and more tires seems like the wrong direction for the MRS.

I believe the Seekonk open tire was the one used by the MRS in 2009.
