Abstract: A disclosed example embodiment of a gauge wheel tire includes a first polyurethane sidewall portion, a second polyurethane sidewall portion, a polyurethane ground-engaging portion, and a polyurethane axial support portion. The first polyurethane sidewall portion is spaced apart from the second polyurethane sidewall portion, and the polyurethane ground-engaging portion extends from the first polyurethane sidewall portion to the second polyurethane sidewall portion and is adapted to contact a ground surface as the gauge wheel tire rotates about an axis of rotation. The polyurethane axial support portion extends from the first polyurethane sidewall portion to the second polyurethane sidewall portion, and is spaced apart from the polyurethane ground-engaging portion to form a gap that allows radial movement of the polyurethane ground-engaging portion relative to the polyurethane axial support portion.

Abstract: A tire includes at least one mark on a sidewall. The mark includes an outer surface including a wavy curved face having two or more and four or fewer peaks. More specifically, the mark includes an outer surface having two or more and four or fewer ridge-like curved faces extending in parallel to each other. The mark may include a circular protrusion protruding axially outward around an entire edge of the mark, and may thus be fringed with the circular protrusion.

Abstract: An aspect of the present invention relates to a tire comprising a sidewall, the sidewall having a surface comprising a surface portion including a hexagonal textured base pattern repeated over the surface portion so as to form a periodic textured pattern providing a high contrast to the surface portion. The hexagonal textured base pattern comprises protrusions and recesses, the protrusions and the recesses of the repeated textured base pattern cooperating to form respective lineal features extending over at least two of the repeated hexagonal textured base patterns.

Abstract: To provide a pneumatic tire that provides improved driving performance on unpaved roads and cut resistance. High blocks and low blocks with different raised heights are provided as side blocks provided in a side region. One of the high blocks and one of the low blocks adjacent to each other in a tire circumferential direction are defined as a block pair. The high block and the low block included in the block pair are partially in contact with each other. Thus, a side groove between these blocks is a closed groove. In each block pair, a pair of contour lines (a first linear portion, a second linear portion, and a third linear portion) define edges on both sides, in the tire circumferential direction, of a top surface of each of the high block and the low block.

Abstract: In a tire, a first side block comprises a first recess which opens so as to be directed toward a first circumferential direction, and a second recess which opens so as to be directed toward a second circumferential direction which is opposite the first circumferential direction in a tire circumferential direction. The first side block comprises a first region, a second region, and a first step which is between the first region and the second region and which is formed by a difference in heights by which the first region and the second region protrude.

Abstract: Provided are a rubber composition, which is capable of providing excellent ozone resistance while suppressing discoloration, and a pneumatic tire using the same.
The rubber composition includes a diene-based rubber, a filler, a phenylenediamine represented by the following formula (1) (wherein R1 and R2 are each an alkyl group or aryl group with 7 or more carbon atoms, provided that at least one of R1 and R2 is an alkyl group with 7 or more carbon atoms), and a quinoline-based antioxidant, and is free of N-phenyl-N′-isopropyl-p-phenylenediamine (IPPD) and N-phenyl-N′-(1,3-dimethylbutyl)-p-phenylenediamine (6PPD).

Abstract: A pneumatic includes a pair of sidewall portions. At least one of the sidewall portions is provided on an outer surface thereof with a first protruding portion arranged on an outer side in a tire radial direction and a second protruding portion arranged on a radially inner side. Both protruding portions are formed so as to be convex outward in a tire axial direction. The second protruding portion has a protruding apex surface formed of a different colored rubber material having a different color from an outer surface of the first protruding portion. A distance in the tire radial direction between an inner edge in the tire radial direction of the first protruding portion and an outer edge in the tire radial direction of the second protruding portion is 40% or more and 220% or less of a length in the tire radial direction of the second protruding portion.
