ABSTRACT:
A vehicle wheel attachment offers an increased tread to support the vehicle on soft ground, snow or sand. A rigid version has a body (5) of revolution which is clamped co-axially against the wheel (1) using a screw device (7,19) anchored to the studs which mount the wheel. The body is generally frusto-conical and may be made buoyant or be ballasted. There are also inflatable (29) and telescopic versions which can be collapsed and stowed against the wheel.
