I got tired of the Kenda tires on my bike. I wanted the best possible puncture-resistant tires for road and gravel/dirt road I could get. These are clinchers with the heavy duty Schwalbe tubes. While they are heavy tires they roll great. First impressions: road traction is outstanding. Smooth dirt, some sand, and gravel are no problem. Very quiet running. Because these tires are designed for e-bikes they are extra durable and long-lasting. They come in at more like 1/3/4 inches wide rather than the nominal 2.0 inches but that could be due to my rims. They will probably widen 1/8 inch or so over time.
