Apparatus for covering the tire of a wheelchair to prevent contact with the tire by the chairs occupant. A pair of fenders cover the upper portion of the large tires on a wheel chair. Each fender includes a body, a front attachment, and a rear attachment. The body is configured to cover the top and a portion of the front of the large tire. The front attachment connects the front of the body to a member on the wheelchair, such as the frame or the handbrake associated with the tire. The rear attachment connects the rear of the body to another member on the wheelchair. The front and rear attachments support the body a slight distance above the large tire. In one embodiment the fender is movable radially relative to the wheel such that the chairs occupant, by pressing down on the fender, is able to brake the wheel.
