The overall diameter of the tire is then the rim diameter plus twice the tire's section height. The ISO 5775-1 standard also defines procedures for measuring tires and for calculating from the marking the maximum dimensions of a tire, which are needed by designers to determine clearance distances to other bicycle components.
Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers. These standards include the parameters of radial force variation , lateral force variation , conicity, ply steer, radial run-out , lateral run-out , and ...

Motorcycle tire changers mainly provide a simple bead loosening system and rim clamps powered manually. Certain motorcycle tire changers can accommodate wheel diameters as small as 10 inches (250 mm) and wheels at least 1 + 1 ⁄ 2 inches (38 mm) wide. [4] In addition, small atv wheels and tires are used on motorcycle tire changers.
Tire factories start with bulk raw materials such as synthetic rubber (60% -70% of total rubber in the tire industry [2] [3]), carbon black, and chemicals and produce numerous specialized components that are assembled and cured. The tire is an assembly of numerous components that are built up on a drum and then cured in a press under heat and ...
