Abstract
Description
この構成により、摩耗進展時のタイヤの排水性能及びウェットグリップ性能を向上させることができる。
この構成により、区画溝の溝体積の減少により低下した排水性能を早期に回復させることができる。
この構成により、トレッド踏面の排水性能が大きく低下することを抑制できる。
この構成により、拡幅部がトレッド踏面に露出する摩耗進展時において、タイヤの排水性能を、より高めることができる。
この構成により、簡易な構成で、摩耗進展時の排水性能及びウェットグリップ性能を向上可能なブロック状陸部を区画できる。
Claims (5)
- トレッド踏面に、区画溝により、又は、前記区画溝及びトレッド端により、区画されるブロック状陸部を備えるタイヤであって、
前記ブロック状陸部は、前記ブロック状陸部の表面の異なる位置からタイヤ径方向内側に向かってそれぞれ延在する第1サイプ及び第2サイプを備え、
前記第1サイプは、サイプ底側に、前記トレッド踏面側よりもサイプ幅が大きくなる拡幅部を備え、
前記第2サイプは、サイプ底のサイプ長手方向で離隔した位置に、タイヤ径方向内側に向かって窪む複数の穴部を備える、タイヤ。 - 前記拡幅部のタイヤ径方向の外側端は、前記複数の穴部のタイヤ径方向の外側端に対して、タイヤ径方向の外側に位置する、請求項1に記載のタイヤ。
- 前記拡幅部のタイヤ径方向の外側端は、前記区画溝のうち最もタイヤ径方向内側に位置する最深部より、タイヤ径方向の外側に位置する、請求項1又は2に記載のタイヤ。
- 前記第1サイプの前記拡幅部の両端それぞれは、前記区画溝に連通する、又は、前記区画溝に連通せずにタイヤ幅方向の前記トレッド端の位置まで到達している、請求項1から3のいずれか1つに記載のタイヤ。
- 前記ブロック状陸部を区画する前記区画溝は、
タイヤ周方向に沿って延在する周方向溝と、
前記周方向溝からタイヤ幅方向に向かって延在する幅方向溝と、を含む、請求項1から4のいずれか1つに記載のタイヤ。
