ADHESIVE BONDING FOR A PNEUMATIC TIRE
First Claim
Patent Images
1. A pneumatic tire assembly comprising:
- a tire having a pneumatic cavity;
first and second sidewalls extending respectively from first and second tire bead regions to a tire tread region, the first sidewall having at least one bending region operatively bending when radially within a rolling tire footprint;
a rigid structure for facilitating operation of the tire assembly, the rigid structure being bonded to the tire by a compound cement of high stiffness such that a stiffness gradient is created between the structure and the tire; and
a sidewall groove defined by groove walls positioned within the bending region of the first tire sidewall, the sidewall groove deforming segment by segment between a non-deformed state and a deformed, constricted state in response to bending of the bending region of the first sidewall while radially within the rolling tire footprint,an air passageway defined by the sidewall groove and deforming segment by segment between an expanded condition and an at least partially collapsed condition in response to respective segment by segment deformation of the sidewall groove when radially within the rolling tire footprint.

Abstract
A pneumatic tire assembly includes a tire having a pneumatic cavity, first and second sidewalls extending respectively from first and second tire bead regions to a tire tread region with the first sidewall having at least one bending region operatively bending when radially within a rolling tire footprint, a rigid structure for facilitating operation of the tire assembly with the rigid structure being bonded to the tire by a compound cement of high stiffness such that a stiffness gradient is created between the structure and the tire, and a sidewall groove defined by groove walls positioned within the bending region of the first tire sidewall.
