This year we used the same wheel we have used for the past two years. They are pneumatic 6.75" mountain board wheels. They give the best traction Ive ever seen and being pneumatic you can adjust the pressure to get more/less if you need it. They are really great. My freshman year..wow 5 years ago. Me and a couple of the guys made a "traction-o-meter" haha. we made a box with a shaft that you put a wheel on and then had a string attached to a force meter and found out the force it took to pull various wheels over the carpet. Anyway another good wheel is wrapping conveyor belt material around the wheel with some epoxy and then screwing them or pop riveting the ends together. We used that type for the 2002 game and it seemed to work well.
