A radial tire (10) is disclosed comprising a pair of bead cores (14), a carcass (16) having one or a plurality of carcass plies (22) extending from one of the bead cores (14) to the other of the bead cores (14) in a toroidal form, a tread portion (18) circumferentially encircling the toroidal form of the carcass (16), and a belt structure (20) disposed radially between the carcass (16) and the tread portion (19). The belt structure (20) has a main belt structure (26), a first, unreinforced rubber layer (30) disposed on a radially outer side of the main belt structure (26), a second, unreinforced rubber layer (32) disposed within the main belt structure (26), and a protective belt layer (28) disposed on a radially outer side of the first, unreinforced rubber layer (30) and a radially inner side of the tread portion (18). A radially outermost belt ply of the main belt structure (26) has a plurality of reinforcement cords. The first, unreinforced rubber layer (30) has a first radial thickness between 0.5 and 4.0 times the diameter of the reinforcement cords of the radially outermost belt ply of the main belt structure (26), and the second, unreinforced rubber layer (32) has a second radial thickness between 0.5 and 2.5 times the diameter of the reinforcement cords of the radially outermost belt ply of the main belt structure (26).
