I did the road to Prudhoe last month. The road is rough, but I dont see how it would SHRED tires. I put on a new set of tires in anchorage, and still have miles left on them after prudhoe and riding all the way home to florida.
The problem with the road is if its raining, or you get behind a water truck in a construction zone, it turns into muck. I lucked out, and had a light rain going up, and no rain the next 2 days coming back to fairbanks. A friend going up the day before I did had so much rain, the cylinder heads on his bmw were caked with a couple inches of mud, and had to be pressure washed off.
Fairbanks to prudhoe bay is 485 miles, with the last 240 being no gas available. I did the trip up in one shot, and it took 15 hours. Broke it up into 2 days coming back.
Take your time, dont over ride the rough spots, and watch for deep soft spots, and everything goes fine. I even saw a guy doing the ride on a Vespa or something similar, gas cans strapped to the seat, and a big ass grin on his face.
