Abstract:
A spring biased tire system for minimizing the negative effects of road hazards comprising, in combination:an elastomeric motor vehicle tire having a pair of essentially parallel side walls and with radially interior ends and radially exterior ends, and an annular road facing surface at the exterior ends and a mounting aperture there through at the interior ends and with the side walls and road facing surface, when mounted on a wheel, forming an inner recess for the containment of air; a plurality of metallic coil springs on the road facing surface, the springs being radially and axially spaced from the side walls and aperture; the springs extending radially outwards from the road facing surface; and a plurality of hemispherical protrusions fabricated of elastomeric material, each protrusion having an outer hemispherical surface adapted to contact the road when in use and an inner hemispherical surface contacting an associated spring, the protrusions being arrayed on the road facing surface as a plurality of axially spaced circumferential hemispheres.
