Re: what did you do to your motor bike today?
I don't recommend the nutechs foam tires for roller drive. The "rubber" seems to be too soft for this, and the tire does not have much for the roller to grab. It is chewing the tire some, but I am going to run it anyway. Wife likes them and doesn't want to change them. We will see what happens if the "knobs" wear down to the rest of the tire. I expect it will work really good then, if the tire doesn't crack up first. Wish me luck.
