I've just returned from 3 months in Canada/Alaska/Arctic Circle/N-W USA. I'd fitted a "knobby" (Continental TKC80) to the front of my BMW R1200GS some time prior to leaving. This tyre was direction-reversed in Alaska after doing 14,900km, and is still on the bike (which is still in transit back to Oz) - with over 31,500km on it, with a couple more thousand km left on it.!
I did about 2,000km of dirt/rock/gravel roads while I was away. Contrary to normal procedure, I did not lower the pressure when off pavement - kept it at 39psi all the time. This tyre handled all surfaces brilliantly. I use a Metzler Tourance on the back, which seems to handle all surfaces well. The Tourance currently has about 16500km on it, with heaps left on it.
