<p>Inserted in the carcass (1) of a tyre (2), at each sidewall (5) thereof, are a first and a second elastomeric reinforcement inserts (13, 15) interposed between a first and a second carcass ply (10, 11) and each growing thinner towards the respective opposite ends of its own section. The reinforcement inserts (13, 15) are joined together in alignment with the maximum-chord point (14) of the tyre (2). A third elastomeric insert (16) of lenticular section, internally covers the first carcass ply (10) and exhibits an area of maximum thickness (16a) in alignment with the junction area (14) between the reinforcement inserts (13, 15). The reinforcement inserts (13, 15) behave like stiff arms, mutually hinged at the junction point (14) thereof, the moving close to each other of said arms being counteracted by a third elastomeric insert (16) behaving like a spring. <IMAGE></p> |
