PNEUMATIC TIRE

To provide a pneumatic tire capable of achieving both wet brake performance and shock burst resistant performance.SOLUTION: In a tread part 2, when a value obtained by dividing a groove area of a lateral groove 40 positioned in a center region Tc by a peripheral length of the center region Tc is denoted as an average lateral groove width Lc of the center region Tc, and a value obtained by dividing a groove area of the lateral groove 40 positioned in a shoulder area Tsh by a peripheral length of the shoulder area Tsh is denoted as an average lateral groove width Lsh of the shoulder area Tsh, a relation between a tire average thickness Gc of the center region Tc and a tire average thickness Gsh of the shoulder area Tsh is in a range of 1.05≤(Gc/Gsh)≤1.35, a relation of the average lateral groove width Lc of the center region Tc and the tire average thickness Gc of the center region Tc is in a range of 0.07≤(Lc/Gc)≤0.12, and a relation between the average lateral groove width Lsh of the shoulder area Tsh and the tire average thickness Gsh of the shoulder area Tsh is in a range of 0.17≤(Lsh/Gsh)≤0.26.SELECTED DRAWING: Figure 3 【課題】ウェット制動性能と耐ショックバースト性能とを両立することのできる空気入りタイヤを提供すること。【解決手段】トレッド部２は、センター領域Ｔｃに位置する横溝４０の溝面積をセンター領域Ｔｃの周長で除した値をセンター領域Ｔｃの平均横溝幅Ｌｃとし、ショルダー領域Ｔｓｈに位置する横溝４０の溝面積をショルダー領域Ｔｓｈの周長で除した値をショルダー領域Ｔｓｈの平均横溝幅Ｌｓｈとする際に、センター領域Ｔｃのタイヤ平均厚さＧｃとショルダー領域Ｔｓｈのタイヤ平均厚さＧｓｈとの関係が１．０５≦（Ｇｃ／Ｇｓｈ）≦１．３５の範囲内であり、センター領域Ｔｃの平均横溝幅Ｌｃはセンター領域Ｔｃのタイヤ平均厚さＧｃとの関係が０．０７≦（Ｌｃ／Ｇｃ）≦０．１２の範囲内であり、ショルダー領域Ｔｓｈの平均横溝幅Ｌｓｈはショルダー領域Ｔｓｈのタイヤ平均厚さＧｓｈとの関係が０．１７≦（Ｌｓｈ／Ｇｓｈ）≦０．２６の範囲内である。【選択図】図３
