摘要： Tire comprising: at least two inserts (104) made of a crosslinked elastromeric material applied in a radially external position with respect to the belt structure in proximity of the axially external edges of said belt structure, each insert comprising: an axially inner portion (104a) which is interposed between said belt structure (105) and said tread band (106) and is tapered toward the equatorial plane of said tire; and an axially outer portion (104b) which is interposed between said carcass structure (101) and the corresponding sidewall (103) and is tapered toward the rotational axis of said tire; wherein said crosslinked elastomeric material has a dynamic elastic modulus (E’), measured at 70°C, lowere than 7 MPa.
