thanks alot!!!

Where in the manual do you see a rule that says that? Answer: you are probably mis-interpreting the rule about nothing that can damage the carpet. Traction wheels are legal and have never been illegal (other than certain types--like anything with metal contacting the carpet).

Recommendation: use them if you can; they can increase traction, which can increase controllability. Definitely a good thing.
