NON-PNEUMATIC TIRE WITH ANNULAR SPOKE REINFORCING WEB
First Claim
1. A non-pneumatic tire, comprising:
- an inner hoop member having an inner surface that defines an inner diameter of the tire;
an outer hoop member including a tread groove region that defines an outer diameter of the tire;
a central web connecting said inner and outer hoop members;
a plurality of elongated, radially aligned cavities on either side of said central web that define a plurality of elongated, radially aligned spokes connecting said inner and outer hoop members, anda reinforcing member on either side of said central web that interconnects a central portion of at least an adjacent pair of spokes.

Abstract
A non-pneumatic tire is provided with an annular reinforcing web that reduces the bending of compression spokes formed in the tire and reduces stresses and strains in the tire. The non-pneumatic tire includes an inner hoop member having an inner surface that defines the inner diameter of the tire, and an outer hoop member having a tread groove region that defines the outer diameter of the tire. A disc-shaped central web portion connects the inner and outer hoop members. A plurality of elongated, radially aligned cavities on either side of the central web defines integrally-formed compression spokes which connect the inner and outer hoop members. The annular reinforcing web is located on and affixed to either side of the central web portion and interconnects a mid portion of each spoke to a mid portion of the spokes on either side of it. Preferably, the annular reinforcing web is reinforced with fiber webbings on its outer side for added strength. The annular reinforcing web allows the tire to be made with less polyurethane material with no reduction in load carrying capability.
