Abstract
A pneumatic tire has: a circumferential groove on each side of the tire equator; oblique grooves extending from the circumferential groove while inclining to one circumferential direction; and lug grooves extending axially outwardly beyond the tread edges from positions axially outside the circumferential groove while inclining to the one circumferential direction. The lug grooves include: a first lug groove comprising an axially inner steeply-inclined part and an axially outer mildly-inclined part; and a second lug groove extending along the mildly-inclined part. The axially inner end of the first lug groove is at a distance La of 8 to 12% of the tread width from the circumferential groove. The steeply-inclined part inclines at an angle larger than an inclination angle of the oblique grooves.
