Clincher Tires tires used 99% of bicycles are type, also as “wire-on.” consist of outer tire a U-shaped section, and separate inner The edges the tire over the of the and air holds everything place. Many suppose that are made of rubber, that’s what visible. This a major — rubber the least of the components that up a The “bead” the edge the tire. most tires, beads consist hoops of steel cable.

beads hold tire onto rim, and in a the “backbones” a tire. most beads steel, some use Kevlar cord instead. fabric is between the beads to the body “carcass” of tire.

This is heart of tire, the that determines shape. The majority of use nylon though some other polyamides. until the cotton/canvas was used.

Some tires thick thread, use thin for the With thin there are threads per (“TPI”) and number is considered an indication of performance. The the TPI the thinner more flexible tire fabric
