1. A pneumatic tire having a tire circumferential direction, a tire width direction perpendicular to the tire circumferential direction, and a tire diametrical direction radially extending, comprising:
a tread portion comprising:
an edge extending along an outer end of the tire width direction of the tread portion; and
a shoulder area in a vicinity of the edge;
a shoulder block provided in the shoulder area; and
a shoulder lug groove;
a sidewall portion extending from the edge toward a radially inside of the tire diametrical direction, the sidewall portion comprising:
a buttress area in a vicinity of the edge;
an annular rib annularly extending along the tire circumferential direction;
a buttress block provided in the buttress area;
a first outside lug groove positioned at a radially outer side of the annular rib, the first outside lug groove extending from the shoulder lug groove without reaching the annular rib; the first outside lug groove comprises a first continuous groove wall comprising a second groove wall portion, a third groove wall portion, and a fourth groove wall portion in this order,
the second groove wall portion opposed to the fourth groove wall portion to form a first portion of the first outside lug groove,
the third groove wall portion opposed to the annular rib, and
a first inside lug groove positioned at a radially inner side of the annular rib, the first inside lug groove extending toward a radially outside of the tire diametrical direction without reaching the annular rib, the first inside lug groove comprises a second continuous groove wall comprising a sixth groove wall portion, a seventh groove wall portion, and an eighth groove wall portion in this order,
the sixth groove wall portion opposed to the eighth groove wall portion to form a third portion of the first inside lug groove,
the seventh groove wall portion opposed to the annular rib,
wherein a second hypothetical line extended along the second groove wall portion and a fourth hypothetical line extended along the fourth groove wall portion do not cross the third portion of the first inside lug groove,
wherein a sixth hypothetical line extended along the sixth groove wall portion and a seventh hypothetical line extended along the seventh groove wall portion do not cross the first portion of the first outside lug groove,
wherein the first extending direction extends from the shoulder lug groove toward the annular rib,
wherein the second extending direction extends radially outward toward the annular rib.
