Mobility Scooter Components
Wheels and Tires
The size of the wheels and tires on a scooter have a direct affect on the scooter’s ability to surmount obstacles and its stability. Scooters are generally equipped with six-, eight-, or ten-inch wheels, although other sizes may also be used.
Some models use the same size wheels both front and rear, while others may have smaller wheels in front and larger rear wheels. Smaller wheels are generally found on front-wheel drive scooters intended for indoor use.
As a rule, the intended use of the scooter should dictate the size of the wheels and tires. The larger the wheels, the more stable the unit. Similarly the larger and wider the tires, the greater the unit’s traction and capacity to manage such obstacles as curb cuts and uneven outdoor terrain. Those same tires, however, may make it more difficult to maneuver the scooter in tighter indoor spaces.
Several types of tires are available for scooters. Manufacturers generally offer a specific tire as standard equipment, with others available as extra-cost options. Pneumatic tires include air-filled tubes and are similar to those found on automobiles. Air pressure should be checked regularly to maintain proper levels, and tires may need to be replaced if punctured.
Foam filled tires are similar to pneumatic tires, but include foam inserts rather than air-filled tubes. These tires cannot be deflated and, therefore, require less maintenance. They may be more expensive than pneumatic tires and may not offer a consistently comfortable ride. The least expensive tire option is the solid rubber tire. These tires require the least maintenance, but provide minimal shock absorption and are intended primarily for indoor use.

Other issues in tire selection include color and tread depth. Most tires are available in black or grey rubber. Black tires are generally less expensive and have a longer life than do grey tires. However, grey tires are specially treated to prevent the marking and scuffing of floors and walls that is common with black tires.
Tires are also available with differing levels of tread. The deeper the tread, the greater the scooter’s traction and ability to handle such outdoor surfaces as mud, gravel, and grass. However, the treads do tend to track dirt and debris indoors. Low-tread or treadless tires eliminate this problem, but should be confined to indoor use or limited outdoor use on paved surfaces.
