A pneumatic tire has paired bead portions, paired sidewall portions, a tread portion, a plurality of lug grooves extending from a shoulder area of the tread portion to reach a buttress area of the sidewall portion, and a block defined by the plurality of lug grooves. The block includes a shoulder block provided in the shoulder area, and a buttress block provided in the buttress area. The buttress area is provided with an annular rib annularly extending along a tire circumferential direction. The lug grooves are comparted into an outside lug groove positioned in an outer side of the annular rib, and an inside lug groove positioned in an inner side of the annular rib. A widened portion is provided in at least part of the plurality of lug grooves so as to enlarge a width of the annular rib.

Provided is a pneumatic tire. Distances from a tire equator of the first to third main grooves and narrow groove respectively are from 5% to 20%, 20% to 35%, 55% to 70%, and 40% to 60% of a tire ground contact half-width TL/2. First lug grooves reach a ground contact edge on a vehicle inner side and terminate within a first rib, second lug grooves communicate with the third main groove and terminate in a second rib, third lug grooves communicate with the second main groove and terminate within a third rib, fourth lug grooves communicate with the first main groove and terminate within a fourth rib, fifth lug grooves intersect the narrow groove and terminate within the fourth rib and a fifth rib, and sixth lug grooves reach a ground contact edge on the vehicle outer side and terminate within the fifth rib.

A tire including a sidewall, wherein the sidewall may include an upper sidewall. The upper sidewall may include a plurality of extruded, angled blocks proximate an outer edge of the tire. The tire may include a plurality of shoulder blocks. The plurality of shoulder blocks may be at the outer edge of the tire on a shoulder.

A pneumatic tyre includes a tread portion, two axially spaced sidewall portions extending radially inwardly from the tread portion, at least one of the sidewall portions being provided with a side protector that protrudes axially outwardly and having an inner end located radially outwardly of a tyre-maximum-width position, and two axially spaced bead portions connected to radially inward of the respective sidewall portions. Each bead portion includes a bead apex rubber having an outer end in the tyre radial direction being located radially inwardly of the tyre-maximum-width position. A radial length of a tyre inner region from a bead baseline to the outer end of each bead apex rubber is in a range of from 0.8 to 1.2 times a radial length of a tyre outer region from a radially outermost position of the tread portion to the inner end of the side protector.

A pneumatic tire has a large number of protector ribs on a side surface thereof. Each protector rib projects from a profile of the tire. The protector rib has an outer end and an inner end. A shape of a cross-section of the outer end is convex inward in an axial direction. The shape of the cross-section of the outer end is preferably a circular arc. A shape of a cross-section of the inner end is convex inward in the axial direction. The shape of the cross-section of the inner end is preferably a circular arc. The tire further has a lateral groove. An intersection angle of an axially outer end of this lateral groove relative to the profile is not less than 100° and not greater than 140°.
