A preferred version of the Invention is a vehicle's auxiliary wheel, each preferably combined with a primary wheel, with a cross section appearing like a ski with a raised tip to run over road bumps, also to prevent the primary wheel to fall to the bottom of a road dip, and a tail to help said fall avoidance, so that the overall structure simulates or approximates a much larger wheel than the primary wheel. Said preferred version has a number of rollers arranged such that some are in front of a primary wheel towards the tip of said ski cross section and some are behind same primary wheel, all raised above the road surface when said surface is flat One variation is that said rollers have a pulley design where a belt runs around them creating a bulldozer wheel effect, for negotiating bumps and dips.
A protective structure referred to in the specification as ski-wheel, to complement at least one road borne wheel of a vehicle, said ski wheel having a number of rollers, at least one roller positioned ahead of the wheel, each roller distant above the road surface when said surface is flat, said roller to surface distance increases the further each roller is from the wheel, which formation resembling rollers installed along the outer arc of a wheel larger than said wheel, ensuring that any road bump is first met by at least one roller before the wheel must run over it and reducing the depth to which the wheel would fall into a road cavity.
