Here in Alaska, a dirt road is officially called an actual "highway." In this case, it's the Denali Highway, from Cantwell to Paxson - only about 125 miles of the most breathtakingly achingly beautiful scenery in North America; the Eastern Alaska Range. But the roads are notorious for being hard on tires. They're dirt and they're full of weird angled rocks. One can easily maintain 40 mph, but here's my question:
Will lowering my inflation pressure to 20-25 psi be harder on the tire? Am I more likely or less likely to get a flat if I leave them at full pressure or lower pressure? Granted, the ride will be smoother for sure, but what will the net effect on my tires be?
What's been your experience?
