I wanted to update my post from page 1. I tried a set of Conti-Motions as a cheaper alternative to PR2s. I burned up the rear by ~5K miles (I usually get ~15K out of PR2s), and the front I took to Alaska.
It got a wire puncture - it looked like maybe something from a steel cable - anyway I couldn't get it patched via gummy worms, it just kept ripping. There was a little truck tire/welding shop ~7 miles away (I was in Burwash Landing - shop in Destruction Bay, Yukon:

Moral of the story - no more cheap tires, esp Conti-Motions! In my case, I'm not saving anything. I'll stick to Michelins from now on and just try to get the best deal I can.
Ya just ain't lived until you're sitting in the mud while it's raining with them big skeeters all around, taking the wheel off and on, sometimes more than once! My brakes have been squealing ever since, but they work!
FYI, just a suggestion, if you are stranded in someplace like the Alcan and you need help from the locals, be nice! And don't be afraid of slipping a $20 here and there as needed, because that's the true cost of a cheap tire. If I hadn't got lucky with getting the new Pirelli Diablo up from Whitehorse, I was going to pay a local with a pickup to load my bike up and take me to either Whitehorse or Fairbanks. Gas + $200 will usually motivate 'em or so I hoped.
