Gaffers tape will only tell you if the wheels and their interaction with carpet is the issue for high current. What Joe is suggesting should reduce the friction with the carpet. If that works, it still points to an issue with your wheel choice. Tape has a tendency to pull off in competition and for that reason should not be considered a permanent solution. Leaving sticky residue on the carpet is considered "damage" to the field which may cause issues at your events. Everything in our experience is pointing at the wheel choice as being the issue. However, there are several other problems that exhibit the same symptoms. The tape will eliminate the most obvious. If your problems continue then there is likely another issue(s). Don't you have a local team that can come and give you guidance?
