摘要： A pneumatic tire provided with a tread portion having at least one circumferential groove with an axially inner groove wall and an axially outer groove wall. The radially outer edges of the axially inner and outer groove walls incline toward the tire equator. The axially inner groove wall intersects the tread face at an inclination angle of from 25 to 45 degrees with respect to the normal line to the tread face. The axially outer groove wall intersects the tread face at an inclination angle of from 0 to 20 degrees with respect to the normal line to the tread face. The tire design reduces running noise without deteriorating aquaplane resistance.

摘要： A tire tread for a pneumatic tire has a center rib and a series of steeply slanted grooves in each side region of the tread, the circumferentially adjacent grooves form blocks extending through the tread side regions. The center rib has a serrated configuration along each lateral side and a supporting chamfer extending from each serration point. Adjacent to each rib chamfer is a chamfer extending from the axially innermost point of the rib at the junction of two adjacent steeply slanted grooves. The rib is provided with high density siping. The tread blocks are siped wherein the siping density decreases from the tread center to the tread shoulders.
