Abstract

PURPOSE:To improve high-speed straight-driving performance and turning performance by dividing a central zone into ribs by a plurality of grooves in the direction of circumference provided in the central part of a tread and further by adding a slant groove so as to block the central part. CONSTITUTION:A plurality of grooves 6 in the direction of circumference, provided in the central part of the tread T, consist of a center-middle groove 6a and a pair of center-side grooves 6b holding the former between. From the side groove 6b the slant groove 7 extends toward the end of the tread, while a lateral groove 8 which joins to the slant groove 7 extends nearly in the direction of the width of the tread T and opens at the end of the tread. The grooves 6 partition the central zone held between the side grooves 6b and both side zones ranging from the side grooves 6b to the ends of the tread. At the time of straight driving, the surface of the tire contacting with the ground is occupied exclusively by ribs 9a and 9b and the small part of the main block 10, and this is favorable for the stiffness of the tread in the direction of a force acting at straight running, while the grooves 6 in the direction of circumference enhance the water-discharging property required at high-speed running.
