I've been on many gravel roads but one project was so hard on tires we also ran out of spares. A farmer had a tire changer and when he was patching my tire said he had so many flats he needed the changer. He said 10 ply tires were necessary there.
Not all gravel roads are the same.
Truth. The roads around my place in CO eat tires like a fat kid at a buffet.
