Rim (wheel) rotating assembly, including the tire. In railroad usage, the conical running surface of the wheels may be called a rim, a wheel tread or a tyre. Rim (wheel) The rim is the "outer edge of a wheel, holding the tire". It makes up the outer circular design of the wheel on which the inside edge of the tire is mounted on vehicles such as automobiles.

Rim (wheel) millennium BC, an iron rim was introduced around the wooden wheels of chariots to improve longevity on rough surfaces. A standard automotive steel wheel rim is made from rectangular sheet metal. The metal plate is bent to produce a cylindrical sleeve, and then the two free edges of the sleeve are welded together. At least one cylindrical flow spinning operation is carried out to obtain the desired thickness profile of the sleeve—and the desired angle of inclination relative to the axial direction in the zone for the outer seat. The sleeve is then shaped to obtain the rims on each
