Abstract
A pneumatic tire for a multiple-tracked vehicle is asymmetrical and has a convex tread section that is curved radially inward and extends to a tire sidewall.
Claims28
A pneumatic tire for a wheel of a multiple-track vehicle, the tire comprising:
- a first sidewall and a second sidewall, the first sidewall extending in a radially inward direction to a first bead attachable to a rim of the wheel and the second sidewall extending in the radially inward direction to a second bead attachable to the rim;
- a tread forming a circumference of the tire and transitioning into the first and second sidewalls via laterally adjacent tire shoulders, the tread including:
- a convex tread section extending in the radially inward direction to an area of the first sidewall, the convex tread section for use at an inside area of the wheel and forming a load-bearing tread section with respect to a road when the wheel is negatively cambered;
- and
- a flat tread section extending in a substantially axial direction from an area of the second sidewall and transitioning into the convex tread section, the flat tread section being wider than the convex tread section;
- the tire being asymmetrical in cross section.

A pneumatic tire system for a multiple-track vehicle, the tire system comprising:
- a wheel including a tire and a rim, the tire including:
- a first sidewall and a second sidewall, the first sidewall extending in a radially inward direction to a first bead attachable to a rim of the wheel and the second sidewall extending in the radially inward direction to a second bead attachable to the rim;
- a tread forming a circumference of the tire and transitioning into the first and second sidewalls via laterally adjacent tire shoulders, the tread including:
- a convex tread section extending in the radially inward direction to an area of the first sidewall, the convex tread section for use at an inside area of the wheel and forming a load-bearing tread section with respect to a road when the wheel is negatively cambered;
- and
- an approximately flat tread section extending in a substantially axial direction from an area of the second sidewall and transitioning into the convex tread section, the approximately flat tread section being wider than the convex tread section;
- and
- a support ring attached to the rim and located completely within an area of the convex tread section, the support ring being disposed a distance from an inner surface of the tire when the wheel is non-cambered;
- the tire being asymmetrical in cross section.

- a wheel including a tire and a rim, the tire including:
- a first sidewall and a second sidewall, the first sidewall extending in a radially inward direction to a first bead attachable to a rim of the wheel and the second sidewall extending in the radially inward direction to a second bead attachable to the rim;
- a tread forming a circumference of the tire and transitioning into the first and second sidewalls via laterally adjacent tire shoulders, the tread including:
- a convex tread section extending in the radially inward direction to an area of the first sidewall, the convex tread section for use at an inside area of the wheel and forming a load-bearing tread section with respect to a road when the wheel is negatively cambered;
- and
- an approximately flat tread section extending from an area of the second sidewall and transitioning into the convex tread section, the approximately flat tread section being wider than the convex tread section;
- and
- a support ring attached to the rim and located within an area of the convex tread section, the support ring being disposed a distance from an inner surface of the tire when the wheel is non-cambered;
- the tire being asymmetrical in cross section;
- wherein the convex tread section includes spikes disposed thereon;
- wherein the spikes are capable of assuming an inoperative position and an operative position, the spikes being retracted with respect to an outer surface of the convex tread section in the inoperative position, the spikes being pushed into the operative position by the support ring when the wheel is cambered such that a wall of the tire presses against the support ring.
