Description
図1は、本実施形態に係る空気入りタイヤ10の断面図である。具体的には、図1は、空気入りタイヤ10のタイヤ幅方向及びタイヤ径方向に沿った断面図である。なお、図1では、断面ハッチングの図示が、一部省略されている(以下同)。図2は、空気入りタイヤ10のトレッドの一部平面展開図である。
図3は、空気入りタイヤ10のトレッド40内部の一部分解平面図である。具体的には、図3は、トレッド40(トレッドゴム)内部に設けられるカーカス50、ベルト層60及び補強ベルト70の一部平面図である。
次に、本実施形態に係る空気入りタイヤ10の作用及び効果について説明する。上述したように、空気入りタイヤ10では、タイヤ赤道線CLを基準とした車両装着時内側(IN側)のトレッド40に形成される溝部のボリュームは、タイヤ赤道線CLを基準とした車両装着時外側(OUT側)のトレッド40に形成される溝部のボリュームよりも少なくなっている。つまり、空気入りタイヤ10では、IN側のネガティブ率は、OUT側のネガティブ率よりも低い。
以上、実施形態について説明したが、当該実施形態の記載に限定されるものではなく、種々の変形及び改良が可能であることは、当業者には自明である。
