Out of all of the tires that I have tested for short course racing, GMZ Cutthroat Tire’s have been the best. I will not use any other tire brand now. Great for racing, mud and pleasure riding.

I was blown away how well these tires worked. They worked amazing on slick wet rock and still did great in a muddy creek as well. Great all around tire. can't wait to get some more miles on these.
