ABSTRACT:
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.
