text: This is because that the main role of the belt in the radial tire is to secure the rigidity of the tire in the circumferential direction thereof (the carcass layer mainly undertakes the rigidity in the radial direction), and if the angle of the belt ply cord with respect to the tire equator surface CL exceeds 25°, the rigidity in the circumferential direction will be reduced, and in order to secure necessary rigidity, it will be necessary to increase the number of belt plies, and the weight of the tire will increase.
