A pneumatic tire has a tread pattern with blocks which are divided by two circumferential grooves extending in the circumferential direction of a tire and eighty-five or more lateral grooves crossing the circumferential grooves in a tread part. In the tread pattern, the quotient S.sub.T /S of the total groove area S.sub.T which is the sum of the circumferential groove area S.sub.G and the lateral groove area Sg in a ground contact surface S when the tire is mounted on a standard rim, inflated with a normal internal pressure and loaded with a normal load, to the ground contact area S is in a range from 0.15 to 0.25, and the rate Sg/S.sub.G of the lateral groove area Sg to the circumferential groove area S.sub.G is in a range from 0.33 to 0.53.
