Soft Tread Wheels – such as Solid Rubber Wheels, Pneumatic Rubber Wheels, High Temperature Rubber Wheels and Polyurethane Wheels. Soft Tread Wheels are generally kinder to the floor surfaces, make less noise and some are even non marking rubber wheels. Polyurethane wheels tend to sit in-between the two types of wheels, as they have a hard nylon, cast iron or aluminium centre with a softer polyurethane tyre bonded on. This makes the polyurethane wheels some of the most versatile wheels in the range. Attema, P. A. J.; Los-Weijns, Ma; Maring-Van der Pers, N. D. (December 2006).

The low resistance to motion is explained by the fact that the frictional work done is no longer at the surface that the vehicle is traversing, but in the bearings. In the simplest and oldest case the bearing is just a round hole through which the axle passes (a " plain bearing"). Even with a plain bearing, the frictional work is greatly reduced because: Central China discovers earliest wheel ruts". Xinhua. Archived from the original on 22 August 2020 .

In modern usage, the 'invention of the wheel' can be considered as a symbol of one of the first technologies of early civilization, alongside farming and metalwork, and thus be used as a benchmark to grade the level of societal progress.
