To provide a tire in which visibility of a reflection portion formed in a tire side portion can be improved, and a tire condition monitoring system using the tire.SOLUTION: A tire 1 comprises a reflection portion 18 disposed in a region from a tire grounding end T on at least one tire side portion to the tire maximum width position A. The reflection portion 18 has an annular reflecting surface 181 continuously extending over the whole periphery of the tire. The ratio between the maximum value of a radial distance Hr1 from a measurement point of a tire inner diameter ID to an inside edge portion of the annular reflecting surface 181 and the minimum value thereof is in a range from 1.00 to 1.04, and the ratio between the maximum value of a radial distance Hr2 from the measurement point of the tire inner diameter ID to an outside edge portion of the annular reflecting surface 181 and the minimum value thereof is in a range from 1.00 to 1.04.SELECTED DRAWING: Figure 2
【課題】タイヤサイド部に形成された反射部の視認性を向上できるタイヤおよび前記タイヤを用いたタイヤ状態監視システムを提供すること。【解決手段】このタイヤ1は、少なくとも一方のタイヤサイド部におけるタイヤ接地端Tからタイヤ最大幅位置Aまでの領域に配置された反射部18を備える。また、反射部18が、タイヤ全周に渡って連続的に延在する環状反射面181を有する。また、タイヤ内径IDの測定点から環状反射面181の内側エッジ部までの径方向距離Hr1の最大値と最小値との比が1.00以上1.04以下の範囲にあり、且つ、タイヤ内径IDの測定点から環状反射面181の外側エッジ部までの径方向距離Hr2の最大値と最小値との比が1.00以上1.04以下の範囲にある。【選択図】図2
