I run that tires non dot twin the pirelli mt 16 on the rear of my bike, I really like it off road but will buy the metzeler next time to stay dot.
The old school tread pattern really hooks up on rocks, roots and mud plus slides nice around corners its a great tire for the off raod racing I do.
I run 10-12 psi with a heavy duty tube and a rim lock if im staying off the pavement, they dont hook up very good above 15.
