Metzeler Tourance, Michelin Anakee, Bridgestone Battlewing, Conti Attack...all 90/10. All excellent on pavement and decent off pavement (thanks for the correction). And I have gotten around 13k miles out of each of them. The review of the Mitas I read indicated that it wore significantly faster.I think you mean off pavement not off road.
90/10 ?? - you'd not catch me with those on Alaska's squirmy construction sites and especially if you are thinking of the Dalton addition.
The Mitas 07 are excellent ...reasonable on pavement ....reasonable off pavement. I like the K60s for wear and off pavement but they can be slippery on pavement with that centre strip.
