To provide at least a tire with a bar code and/or a two-dimensional code that eliminates durability such as erasable mark resistance and so on of a mark for tire which is used in various harsh conditions, which are problems in a thermal head marking method with good visibility, cheap price and stability, for a concave and convex marking method in marking of altitude information to a black tire.SOLUTION: In a tire, a marking base material, in which at least a bar code and/or a two-dimensional code is formed by thermal head printer output means on an image reception layer surface of a label base material having a white filler-containing ink mark reception layer provided on one surface of a heat-resistant thermoplastic resin film and a rubber adhesive layer on the other surface thereof, exists in such a manner that the rubber adhesive layer surface contacts a bottom surface part in a tire recess simultaneously formed during vulcanization molding of a green tire, and the label base material with a formed mark is integrated via the rubber adhesive layer and exists in the recess in the state of contacting a tire rubber after vulcanization.SELECTED DRAWING: None
【課題】黒色タイヤへの高度情報のマーキングにおいて、凹凸刻印マーキング法に対して、視認性が良好で且つ安価で安定なサーマルヘッドマーキング法の問題点である種々な過酷な条件で使用されるタイヤ用マークの耐消マーク性等の耐久性を解消する少なくともバーコード及び/あるいは2次元コード付きタイヤを提供すること。【解決手段】耐熱性熱可塑性樹脂フィルムの一方の面に白色フィラー含有のインクマーク受像層を設け、他方の面にゴム系粘着層を有してなるラベル基材の受像層面に、サーマルヘッドプリンタ出力手段により少なくともバーコード及び/あるいは2次元コードが形成されたマーキング基材が、グリーンタイヤの加硫成型の際、ゴム系粘着層面が、金型により同時形成されるタイヤ凹部内の底面部に接触してあり、マーク形成されたラベル基材がゴム系粘着層を介して一体となって加硫後のタイヤゴムと接着状態で凹部内にあるタイヤとする。【選択図】なし
