Testing out the new tires against some XTR370's on a rough hill 

The hills are getting steeper and rougher. The machines are getting bigger and bigger. We need our tires to keep up. The only way to know which ones you like better are to try many different ones. In this video I am running a set of 35in MRT Desert Storm. These offer a kevlar sidewall for extra protection. More to come on how I feel about them.
