The Wheel of a wheel chair is also an important component.
Most wheelchairs use four wheels, two large wheels at the back and two smaller ones called casters at the front.
The standard tire used for the rear wheels on most wheelchairs is a pneumatic tire, for which the standard size is 24 inches. However, smaller and larger sizes are also available. Many manufacturers now also offer other types of tires--such as solid tires, semi-pneumatic, or radial tires--at extra cost. Mag wheels and off road wheels also are options on some chairs. Casters, too, vary in size (ranging from six to eight inches in diameter) and composition (pneumatic, solid rubber, plastic, or a combination of these).
Power based chairs, on the other hand, use four wheels
of the same size, usually 8 to 10 inches in diameter. These chairs may have pneumatic, semi-pneumatic, or solid tires.
