Abstract
A stabilizing system for a pneumatic tire and wheel assembly includes complimentary projections and grooves on internal regions of the tire which contact each during an under-inflated condition. The projections and grooves mate with each other during the under-inflated condition to provide mechanical and positive interconnection between the regions in a direction of travel thereby inhibiting lateral movement between the tire and the rim.
Claims16
A pneumatic tire and wheel assembly comprising a wheel rim and a pneumatic tire mounted on the wheel rim;
- the pneumatic tire comprising a ground-engaging portion and a pair of sidewall portions which define an inflation chamber, these portions including internal tread-adjacent regions which contact respective internal rim-adjacent regions during an under-inflated condition;
- the pneumatic tire also comprising a stabilizing system comprising projections on one of the internal regions and complementary grooves on the other internal regions which mate with each other during the under-inflated condition to provide mechanical and positive interconnection between the regions thereby inhibiting lateral movement between the pneumatic tire and the rim.
A pneumatic tire, comprising:
- a ground-engaging portion including a tread;
- a bead portion;
- a pair of sidewall portions between the ground-engaging portion and the bead portion, together which define an inflation chamber, and
- a stabilizing system within the inflation chamber on a sidewall portion, comprising a pair of mating portions which contact each other during an under-inflated condition within the inflation chamber.

A pneumatic tire, comprising:
- a ground-engaging portion including a tread;
- a bead portion;
- a pair of sidewall portions between the ground-engaging portion and the bead portion, together which define an inflation chamber, and
- a stabilizing system within the inflation chamber on a sidewall portion, comprising a pair of regions which contact each other during an under-inflated condition within the inflation chamber, at least one of the regions including projections which mate with grooves in the other region upon a collapse of the sidewall portion during an under-inflated condition within the inflation chamber.
