Abstract
PURPOSE:To provide satisfactory ground contact property and high speed durability in a tire having a sheet of belt folded into at least three layers and embedded in the tread portion, by specifying the width of the upper and lower layers of the folded belt, tensile elastic modulus of cord in the belt, etc. CONSTITUTION:A pneumatic tire is provided with a carcass 4 turned back on both end area around a bead core 7 and a belt 2 surrounding the carcass 4 and folded into at least three layers is embedded in the tread portion 1. Cords in the respective layers of the belt 2 in such tire are arranged to sandwich the equator surface of the tire at angle of 5-30 deg. thereto algernatively in opposite directions, and the width of the belt is rendered 80-120% of the width of ground contact on road face. Also, the width of the upper and lower layers of folded belt is made larger than a half width of the belt itself. Further, the cord of the belt is made to have 40-200g/D of tensile elastic modulus, and the tread portion 1 is formed with two main grooves 1a, 1b.
