The first bicycle "tires" were iron bands on the wooden wheels of velocipedes. [3] These were followed by solid rubber tires on penny-farthings. [4] The first patent for "rubberized wheels" was granted to Clément Ader in 1868. [5] In an attempt to soften the ride, rubber tires with a hollow core were also tried. [6]
Early rubber tires were solid (not pneumatic). Pneumatic tires are used on many vehicles, including cars , bicycles , motorcycles , buses , trucks , heavy equipment , and aircraft . Metal tires are used on locomotives and railcars , and solid rubber (or other polymers) tires are also used in various non-automotive applications, such as casters ...
The drawbacks to airless tires depend on the use. Heavy equipment operators who use machinery with solid tires may become fatigued. Any airless tire will be heavier than the rubber tire it is meant to replace. However, airless tires are not popular with hardcore off-roaders, as those vehicles often need to travel long distances at highway speeds.
One particular model, made by Pope Manufacturing Company in 1886, weighs 36 pounds (16 kg), has a 60-spoke 53-inch (130 cm) front wheel and a 20-spoke 18-inch (46 cm) rear wheel. It is fitted with solid rubber tires. The rims, frame, fork, and handlebars are made from hollow, steel tubing. The steel axles are mounted in adjustable ball bearings ...
An early wheel made of a solid piece of wood. A wheel is a rotating component (typically circular in shape) that is intended to turn on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating ...
Figure 1 Hard wheel rolling on and deforming a soft surface, resulting in the reaction force R from the surface having a component that opposes the motion. (W is some vertical load on the axle, F is some towing force applied to the axle, r is the wheel radius, and both friction with the ground and friction at the axle are assumed to be negligible and so are not shown.
