摘要： The end of the folded-back ply in the tread width direction of the tire (1) extends beyond the tire maximum width, and the height of the bead filler is 30% or less than the tire sectional height. The maximum thickness of the reinforcing rubber layer is less than the maximum thickness of the bead filler. The tread width is greater than or equal to 81 % of the tire maximum width. The radius of curvature of the carcass layer on the extension line passing through the tire maximum width position and extending in the tread width direction is 30 mm or greater.

摘要： Tires having a sidewall that is covered with a protective coating that may cover the exposed surface of one or both of the sidewalls. The protective coating is a rubber composition that is based upon a cross-linkable elastomer composition that includes, per 100 parts by weight of rubber, ), between 25 phr and 45 phr of natural rubber, between 25 phr and 45 phr of polybutadiene rubber and between 30 phr and 40 phr of EPDM. Additionally the rubber composition may include between 20 phr and 50 phr of carbon black and a curing system. The curing system may be a peroxide curing system. In addition, the protective coating may be applied to the sidewall at a thickness of between 0.4 mm and 1 mm.

摘要： Provided is a tire and a tire surface printing method which are capable of reducing man-hours and cost required for application of printing on the tire surface. The tire and the tire surface printing method include, on an outer surface of at least one of side portions (3) thereof, a printed region (5) formed by printing. The printed region (5) includes: a dark-colored portion (7) having a black color, which is a base color of the tire; and a bright-colored portion (9) that has a color different from the black color and that is located to surround the dark-colored portion (7). The dark-colored portion (7) is not applied with any paint, and the bright-colored portion (9) includes a white-colored layer (11) that includes a white color paint and that is located as the lowermost layer being in contact at least with the outer surface (3a) of the side portion (3).
