I recently started riding and enjoy it. I bought a couple of bikes for my son and my self. What I have noticed is that I like the tires on the bikes they rent downtown. The ride is smoother, I.bought a mountain to bike to support my weight and the tires are big. However the tires on the dt bikes are narrow ride smoother and hold my weight just fine. Where can I go to get something similar or those tires? Any help is appreciated.
