ABSTRACT:
A pneumatic tire having at least two belt plies provided radially outwardly of a carcass ply in the tread. A belt cover ply is disposed radially outwardly of the at least two belt plies. The belt cover ply has reinforcing cords that extend in the circumferential direction of the tire and is covered with coating rubber. The belt cover ply extends beyond the edges of one of the at least two belt plies having a maximum belt width to have extension portions that extend at least 10 mm axially of the tire therefrom. The coating rubber of at least the extension portions of the belt cover ply is formed of rubber having a tan delta at a temperature of 60.degree. C. that is equal to or less than 0.1, and the ratio h/SH of a tire radial-direction length h between the edges of the extension portions and the edges of the belt ply having the maximum belt width to the tire section height SH is equal to or less than 1.5/100.
