A pneumatic radial tire having a tread portion comprising a first plurality of grooves, the grooves in the central region of the tread following a particular path across the tread. The grooves are spaced circumferentially apart a distance of about 2 to 3% of the circumference of the outer surface of the tread. A second plurality of grooves are provided in the central portion each of which follow substantially the same path as the first plurality of grooves and are substantially the mirror images of the first plurality of grooves. The second plurality of main grooves are also spaced circumferentially apart a distance in the range of about 2 to 3% of the circumference of the tire.
