tire

Abstract

The present invention provides a tire provided with the following on the sidewall portion (104): a black rubber layer (113), a pollution preventing rubber layer (112) disposed adjacent to the black rubber layer, and a pollution preventing rubber layer (112) disposed on the A colored layer (111) on the surface of the rubber layer and exposed on the outer surface of the sidewall portion. The outermost edge of the stain preventing rubber layer in the radial direction of the tire is located radially inward of a position where the tire width is the largest. The present invention also provides a tire having a colored layer (207) provided on the outer surface of the tire, and an underlayer rubber (208) provided on the inner side of the tire of the colored layer. The colored layer is formed by curing a UV-curable paint, and the underlayer rubber uses a rubber composition containing 0-1.5 parts by mass of an anti-aging agent per 100 parts by mass of rubber. The present invention further provides a tire, wherein: a colored layer (302) is provided on the surface of the sidewall portion (301), marks (303) are displayed on the colored layer, and The distance between the ply cords (370) is 4.0 mm or less.

Description

technical field [0001] The invention relates to a tire, including a pneumatic tire and a solid tire. Background technique [0002] A tire is generally provided with a colored layer (or paint layer) to place decorations and the like on the outer surface of the sidewall portion. Such tires, which are now widely used, include non-staining or slightly staining sidewall inner rubber that does not contain staining anti-aging agents to prevent the trim parts from being stained by the anti-aging agents contained in the surrounding rubber. Refer to JP H4-121205 (Patent Document 1). This technique, generally known in the art, allows the trim part to be located away from the anti-aging agent-containing black rubber layer. [0003] Coloring such as surface coating and printing on tires has also been widely performed to improve the decorativeness or visibility of the tires. In such coloring, although heat-curable or solvent-volatile paints have been generally used, ultraviolet (UV) cu...
