The shoulder lateral grooves extend axially outwardly from an axially inner edge of the shoulder rib portion so as to terminate at an axial distance of from 78 to 88% of the axial width of the shoulder rib portion from the above-mentioned axially inner edge. The depth of the circumferential grooves is 15 to 20 mm. The depth of the crown lateral grooves is 9 to 30% of the depth of the circumferential grooves. The depth of the shoulder lateral grooves is 9 to 25% of the depth of the circumferential grooves. The tread width TW is in a range of 0.78 to 0.87 times the cross sectional width SW of the tire.
