PROBLEM TO BE SOLVED: To provide a tire in which surface temperature rising due to solar radiation can be suppressed by elongation of an infrared light selective reflection layer corresponding to tire rubber elongation.SOLUTION: A tire includes an infrared light reflection layer 2 on a surface rubber 7, 8 of a tire side plane, the infrared light reflection layer 2 includes infrared light interference particles having a cholesteric liquid crystal structure which reflects an infrared light of wavelength not less than 700 nm, and the tensile breakage elongation percentage of the tire expressed by the following equation (1) is not less than 10%. Equation 1 Tensile breakage elongation percentage (%)=100%*(L-Lo)/Lo (Lo expresses the sample length when the tensile testing methods for vulcanized rubber (JIS K 6251-1993) is performed by using a lamination body of the infrared light reflection layer 2 and the tire side plane as a sample, and L expresses the sample length upon sample breakage in the test.) |
