Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
78 words
In a vehicle tire comprising an inflatable tire carcass adapted to receive a removable tread ring in locked relationship under inflated conditions, said ring including an armor of metallic or polyamide members to provide resistance to tension in a longitudinal direction of the ring, the improvement wherein the tread ring has a layer of see-through elastomer suitable for use in a tire covering the inside of the armor to permit the position of each member to be determined
Claim 2
Dependent Claim
78 words
In a vehicle tire comprising an inflatable tire carcass adapted to receive a removable tread ring in locked relationship under inflated conditions, said ring including an armor of metallic or polyamide members to provide resistance to tension in a longitudinal direction of the ring, the improvement wherein the tread ring has a layer of see-through elastomer suitable for use in a tire covering the inside of the armor to permit the position of each member to be determined
Claim 3
Dependent Claim
25 words
The pneumatic tire of claim 1 wherein the armor is composed of spirals of helically wound metallic members and the see-through elastomer is a polyurethane.
Claim 4
Dependent Claim
17 words
The pneumatic tire of claim 1 wherein the polyurethane of the see-through elastomer is a nondiscoloring polyurethane.
Claim 5
Independent Claim
77 words
A method of inspecting a pneumatic tire which includes a carrying case and a tread ring having a see-through elastomer layer over the armor in said tread ring, said armor containing metallic or polyamide members to produce resistance to tension in a longitudinal direction of said ring, comprising deflating the carrying case, removing the tread ring and inspecting the armor through said see-through elastomer layer to determine the spacing and position of the members in the armor.
Claim 6
Independent Claim
77 words
A method of inspecting a pneumatic tire which includes a carrying case and a tread ring having a see-through elastomer layer over the armor in said tread ring, said armor containing metallic or polyamide members to produce resistance to tension in a longitudinal direction of said ring, comprising deflating the carrying case, removing the tread ring and inspecting the armor through said see-through elastomer layer to determine the spacing and position of the members in the armor.
