A special type of tire is the tubular tire, because here the tire is directly combined with the tube. In the tubular tire is a tube sewn directly into the tire and is glued to special rims. This variant is mainly used in road cycling. Many professionals still rely on this system, the reason for which is supposed to be a particularly smooth rolling and cornering performance. However, a modern folding tyre is in no way inferior to a tubular tyre in terms of rolling resistance. A clear advantage of the system is that it does not jump off the rim in the event of a flat tire. Thus, the cyclist can roll out without danger and in the race even cover a few meters until the material truck is on site. The big disadvantage is the assembly, by sticking on the rim is a tire change considerably more complex than other bicycle tires.
