Abstract: A tire 10 has an endless decorative band 2 on a surface of a sidewall 1. The decorative band 2 has one or more first indicative sector 3 and one or more second indicative sector 4 which are arranged alternately and consecutively in the circumferential direction. The first indicative sector 3 consists of a background portion 5 which continuously leads to the sidewall portion 1 adjacent to the first indicative sector with a uniform surface roughness value, and a foreground portion 6 which is arranged in the background portion 5 and forms marks by having a surface roughness value larger than that of the background portion 5. A background portion 7 constituting a part or whole of the second indicative sector 4 has a surface rougher than any of the sidewall portion 1 and the background portion 5 of the first indicative sector 3.

Abstract: The present invention provides a tire capable of suppressing a crack or cracks possibly occurring from a part of a decorative band and improving a visibility of marks formed on the decorative band. A tire 10 has an endless decorative band 2 on a surface of a sidewall 1. The decorative band 2 has one or more first indicative sector 3 and one or more second indicative sector 4 which are arranged alternately and consecutively in the circumferential direction. The first indicative sector 3 consists of a background portion 5 which continuously leads to the sidewall portion 1 adjacent to the first indicative sector with a uniform surface roughness value, and a foreground portion 6 which is arranged in the background portion 5 and forms marks by having a surface roughness value larger than that of the background portion 5.
