Abstract

The tyre comprises a radial carcass having at least two piles 1,2 or groups of plies between which is incorporated, in each sidewall of the tyre, a supporting component (10) made of a soft elastomeric material, of lenticular cross-sectional shape, which extends from a filler (8) (which overlies the bead core (3)) to a location under the belt (5,6,7) which underlies the tread band (4). The elastomeric material of component (10) has an ISO hardness not exceeding 47 and a thermal stability not less than 20 minutes for a temperature increase not exceeding 25 DEG C. Instead of the load, in the deflated tyre, being borne by the material of the sidewalls, the component (10) tends to maintain the tyre shape. <IMAGE>
