A tire has an outer surface comprising a decorative portion which is visible and provided with micro-protuberances at a density of from 2 to 10 micro-protuberances per 1 sq.mm, and the micro-protuberances include a recessed micro-protuberance provided at its top surface with a recess.

A tire has a visible outer surface comprising a decorative region provided with a plurality of micro-protrusions each comprising a recess and a wall portion. The wall portion surrounds the recess to form a protrusion's apex having an upper surface, and the upper surface of the wall portion comprises at least two peak points in the protruding-height direction of the micro-protrusion, at which the protruding height of the wall portion becomes local maximum.

Provided is a pneumatic tire with which the same driving safety as prior arts can be ensured and an improvement in fuel efficiency performance and durability performance is achieved. In this pneumatic tire, the tire radial direction outside end section of a chafer is disposed on the tire surface part, the loss tangent tan δ70° C.-SW of a side wall, the loss tangent tan δ70° C.-C of the chafer, complex elastic modulus E*70° C.-SW of the side wall, and the complex elastic modulus E*70° C.-C of the chafer under the condition of 70° C., an elongation of 1%, and a frequency of 10 Hz, and the loss tangent tan δ150° C.-SW of the side wall, and the loss tangent tan δ150° C.-C of the chafer measured under the condition of 150° C., an elongation of 1%, a frequency of 10 Hz satisfy the following expression. tan δ70° C.-SW+tan δ70° C.-C≤0.25|tan δ70° C.-SW−tan δ70° C.-C|≤0.07 E*70° C.-C−E*70° C.-SW≤6.5 MPa tan δ150° C.-SW+tan δ150° C.-C≤0.20

A tire having a rubber assembly including a first rubber member, a second rubber member, and a third rubber member which are arranged in series in the cross-section including the tire rotational axis. The method includes: extruding the unvulcanized rubber assembly as two separate parts which are a first extrusion rubber portion and a second extrusion rubber portion divided at a division surface passing through the unvulcanized first rubber member; winding the first extrusion rubber portion into a base annular body; and forming the unvulcanized rubber assembly by winding the second extrusion rubber portion so that only the first rubber member included in the second extrusion rubber portion overlaps with the first rubber member included in the base annular body.

A pneumatic tire has a non-stretchable tread (30) flanked by two shoulder regions (34), and two non-stretchable bead regions (36) for mounting the tire to a wheel, each bead region being connected via a sidewall to the corresponding bead region. Each sidewall has a first portion (38) extending inwardly relative to a width of the tire from one of the bead regions (36) to a deflection region (40), and a second portion (42) extending outwardly relative to the width of the tire from the deflection region (40) to a corresponding one of the shoulder regions (34). A non-stretchable girth-limiting configuration (44, 46, 56) and a radial reinforcing structure (48, 50, 52) are associated with the first portion (38) of each of the sidewalls, thereby limiting radial flexing of first portion (38) and maintaining an annular concavity between the bead region (36) and the shoulder region (34).

A pneumatic tire includes a lug grooves extending in a shoulder region of a tread portion in a width direction up to a sidewall portion, a shoulder block and a side block defined by the lug grooves, in which the side block located outward of the shoulder block in the width direction is ridged higher than the shoulder block, at least a part of the lug grooves being each a closed lug groove closed by a ridge portion provided therein, the ridge portion being continuous to the side block located on both sides of the closed lug groove in the circumferential direction, the ridge portion including a first narrow groove with a smaller groove width and a smaller groove depth than the lug groove, extending in the width direction, and at least one end of the first narrow groove penetrating toward the closed lug groove or the sidewall portion.
