“I fear that I may have bought the wrong type of tire for my use. I should have bought a road type tire instead as I am travelling alot on Concrete paved bike tracks & dual purpose footpaths. The knobs are wearing down quicker than I would prefer . . The tires are quite thin in the tire wall too, yet seems to have good hysteresis properties with a lower type rolling friction but I feel that they bottom out too easily even when I am running 80 PSI pressure. With my weight, I should go for a heavier type tire next time.”
