: Does anyone know a quick yet effective method for putting little grooves in the wheelchair wheels provided by FIRST? We would like to groove all four of our wheels to provide better traction when we get to NYC. What tools can be used? Is there a specific spacing between grooves that works best on the carpet on the playing field?
In the past we've used a soldering gun to melt grooves. Get the iron hot and push it into the tire. The tire material melts and squeezes out to make ridges. They wear down really fast though. We've never done an exhaustive study, but they don't seem to make a whole lot of difference. Spacing doesn't seem to matter much either.
