I'm using trackmasters also. So far they seem good. I have'nt had a chance to use them in the slick clay yet.

 

FYI next time you buy tires... Try Pirelli Scorpion Pro tires. They are the best dot approved tire that I had ever used. works great in the mud or wet clay (use at 10 or less psi for best results in wet conditions). much better than trackmasters. http://www.americanmototire.com/cata...th=265_346_361
