Abstract
A tire has a first sidewall portion having a reference surface and provided with a raised part. The raised part has a top surface having a second color. The tread portion is provided with shoulder lateral grooves and shoulder blocks The shoulder block has a first block wall surface inclined to the axially outer side toward the radially inner side from a first tread edge The radially inner edge of the first block wall surface is separated from the bottom surface of the shoulder lateral groove by at least 3 mm, and located axially inside a tire radial direction line passing through a position corresponding to the midpoint of the protruding height of the raised part.
Claims19
A pneumatic tire comprising:
- a tread portion having a first tread edge;
- and
- a first sidewall portion extending inward in the tire radial direction from the tread portion,
- wherein
- the first sidewall portion comprises
- a reference surface having a first color, and
- a raised part protruding outward in the tire axial direction from the reference surface at a protruding height h in a first cross section of the tire including the rotational axis of the tire and the raised part,
- the raised part has a top surface facing outward in the tire axial direction and having a second color different from the first color,
- the tread portion is provided with
- a plurality of shoulder lateral grooves having a bottom surface extending outwardly in the tire axial direction beyond the first tread edge and smoothly merged into the reference surface of the first sidewall portion, and
- a plurality of shoulder blocks divided by the shoulder lateral grooves,
- at least one of the shoulder blocks is located on the outer side in the tire radial direction, of the raised part,
- the at least one shoulder block has a first block wall surface extending from the first tread edge toward the inner side in the tire radial direction, while inclining to the outer side in the tire axial direction, so as to have a radially inner edge,
- in the above-said first cross section, the radially inner edge of the first block wall surface is separated from the bottom surface of the shoulder lateral groove, so that a minimum distance from the radially inner edge to the bottom surface is not less than 3 mm, and
- in the above-said first cross section, the radially inner edge of the first block wall surface is located inward in the tire axial direction of a straight line drawn parallel to the radial direction of the tire passing through a position corresponding to a midpoint (h/2) of the protruding height h of the raised part.
