Radial tires for passenger cars with improved steering stability

摘要

The present invention relates to a radial tire for a passenger car, which can improve both vehicle response performance and balance between the vehicle and the tire, with improved steering stability.;In the conventional belt structure, a so-called pulling phenomenon occurs in which the first belt 1 moves to the right and the second belt 2 moves to the left when the vehicle travels in a straight line. It is pointed out as a factor that lowers the steering stability caused more severely in the tire formed by the present invention, the present invention is a plurality of belts are stacked between the carcass and the tread layer is installed in the passenger car radial constituting the belt portion of the tire reinforcement layer In the tire, the second belt (2) is formed into an uneven shape, and the first (1) and the third belt (3) formed in narrow widths are inserted into the plurality of grooves (20) formed on the upper and lower surfaces of the second belt. However, the inclination direction of the cords 11 and 31 arranged inside the first and third belts 3 and 3 is different from the inclination direction of the cords 21 arranged in the second belt 2. Staggered in the opposite direction By, it will be effective to improve the belt durability with improved handling and stability.
