Abstract

PURPOSE: To improve the durability of belt layers, by forming the 1st layer of belt layers provided in multiple to be in a given split construction having a given cord angle, providing its split portion with a given organic fibre cord layer, and placing the cords of a 2nd and a 3rd layers so as to be intersectingly arranged to each other.
CONSTITUTION: A 1st layer 4a nearest to the carcass layer 3, of belt layers 4 is formed in a split construction having a cord angle of 40W75deg., allowing it to be split at a crown center area T, and an organic fibre cord having the total strength of the min. 240kg/cm per unit width is placed on this split portion as an organic fibre cord layer 5 being placed at a cord angle of 0W10deg. Further, cord arrangement on the both sides of the 1st layer 4a is set to be symmetrical against a tire center. The cord angles of a 2nd and a 3rd layers 4b, 4c are arranged to be 10W30deg. and the both layers are placed so as to be intersected to each other. This constitution will improve the durability and the dimensional stability of the crown portion on a rough road, thus improve the durability of a belt.
