First, the tire has an outer tread surface with a crown radius. Secondly, the tread has a pattern with a plurality of circumferential grooves and lateral grooves arranged to reduce uneven contact pressures caused by radial forces carried by the tire's ribs. Thirdly, the spacing of the ribs is randomly varied around the circumference of the tire to broaden a vibration spectrum caused by the ribs and reduce peak vibrations. Fourthly, a wheel rim that supports the annular body is provided with a structurally incorporated hoop to reduce deflection of the wheel rim during tire operation.

Spurs can be provided at these locations, generally as extensions of the longer portion, to protrude into the back of the next location around the circle and thereby limit the distortion under load.

Abstract: A road wheel for a track laying vehicle comprising a metallic disc and rim part wherein the rim portion of the part is of toroidal geometry. An elastomeric tire .[.tread.]. .Iadd.part .Iaddend.is bonded to the outer surface of the rim part and has a .Iadd.tread with .Iaddend.a cylindrical outer face adapted for engagement with the track treads of the track laying vehicle. The cross sectional thickness of the metallic disc and rim part is substantially uniform throughout the same. The rim portion has a radially in-turned flange at the free end thereof extending at an acute angle to the axis of the road wheel. The disc portion merges with the rim portion integrally through a bend portion and extends radially inwardly a given distance to provide a track lug wear surface. The disc portion also has a reverse bend offset axially toward the outer free edge of the rim portion to provide clearance for track guide lugs in the operation of said wheel.
