Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
A vehicle tire comprising tread portion, side wall portions and rim engaging beads at the inner extremities of said side wall portions to form, with a wheel rim, an enclosed air chamber, a plurality of parallel annular strongly reinforced ridges of trapezoidal section coaxially positioned, the broad bases of said, trapezoidal ridges being against the inner surface of said tread portion said ridges being contiguous with each other to provide V shaped spaces therebetween, said ridges cooperating with the inner surface of said tread portion to transmit radial compressive forces applied against the outer surface of said tread portion to said rim engaging beads by tension in said side walls at the side of said tire remote from said applied compressive forces, said ridges each including at least one annular spring metal reinforcing rod.
Claim 2
Dependent Claim
134 words
