More product description: Cloth fabric is woven between the two beads to form the body or "carcass" of the tire. Bike shops sell it, and they'll put it in for you if you don't know how to remove your valve stem. Generally, wider tires call for lower pressures, narrower tires call for higher pressures. Traditionally, each major bicycle-producing country had its own system for measuring and designating tire and rim sizes. A wider front tire makes sense in many applications, however, when handling and ride comfort are considered. With your fingers, work the lip of the tire into the wheel rim, on only one side. Many people suppose that tires are made out of rubber, because that's what is visible. Fat Tire Bike Week is an equal opportunity service.
