Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
88 words
A pneumatic tire having at least one rubber sidewall, a tread surface of a predetermined width, a carcass and a plurality of reinforcing layers therebetween, said reinforcing layers having a width less than 95 percent or more than 105 percent of the width of said tread surface, the improvement comprising: said rubber sidewall extending to a point between said carcass and an edge of at least one of said reinforcing layers for a distance corresponding to at least 10 percent of the maximum width of said reinforcing layers.
Claim 2
Dependent Claim
88 words
A pneumatic tire having at least one rubber sidewall, a tread surface of a predetermined width, a carcass and a plurality of reinforcing layers therebetween, said reinforcing layers having a width less than 95 percent or more than 105 percent of the width of said tread surface, the improvement comprising: said rubber sidewall extending to a point between said carcass and an edge of at least one of said reinforcing layers for a distance corresponding to at least 10 percent of the maximum width of said reinforcing layers.
Claim 3
Dependent Claim
26 words
A pneumatic tire as claimed in claim 1 wherein both the rubber sidewalls are extended between the respective edges of the reinforcing inserts and the carcass.
Claim 4
Dependent Claim
29 words
A pneumatic tire as claimed in claim 1 wherein the radius of curvature of the edges of the tread is between 8 and 20 percent of the tread width.
Claim 5
Dependent Claim
80 words
A pneumatic tire as claimed in claim 1 wherein the individual reinforcing inserts have at least three different widths and wherein the cord threads of the individual reinforcing inserts run alternately in mutually perpendicular directions, and wherein the sum of the widths of the individual reinforcing inserts on which the cord threads run in one direction is substantially equal to the sum of the widths of the individual reinforcing inserts in which the cord threads run in the other direction.
