Claim 2
Dependent Claim
24 words
A radial tyre for an automobile or other vehicle, the tyre having along each bead a reinforcing layer 30 comprising cords of carbon fibers.
Claim 3
Dependent Claim
37 words
A radial tyre as claimed in claim 1, wherein said reinforcing layer comprises 20 to 60 cords of car bon fibers embedded per 5 cm in coating rubber having a 100% modulus of 30 to 70 kg/cM2.
Claim 4
Dependent Claim
