<p>A heavy-transport radial tire (1) having two annular shoulder cushions (14) made of elastomeric material with a relatively low M200% modulus, and each located at a respective shoulder (9) between a reinforced body ply (4) and a tread belt (10) defined by a number of superimposed tread plies (11); and wherein a belt cushion gum strip (18), made of elastomeric material with a relatively high M200% modulus but lower than the M200% modulus of a coating skim (13) of the reinforced tread plies (11), is interposed between each annular shoulder cushion (14) and the tread belt (10) to cover at least the respective edges (20, 22) of those (11a, 11b) of the reinforced tread plies (11) facing the annular shoulder cushion (14). <IMAGE></p> |
