Description
また、本実施形態では、第1凸部11が、タイヤ径方向外方Xoに行くほどバットレス部10の外壁面10aからの突出高さが漸次高くなっているため、タイヤ転動時に第1凸部11で発生するトラクションを増大することができ、泥濘地での駆動性能をより一層向上することができる。
Claims (5)
- トレッド部と、サイドウォール部と、前記トレッド部と前記サイドウォール部の間に設けられたバットレス部と、前記バットレス部にタイヤ周方向に間隔をあけて設けられた複数の第1凸部と、前記バットレス部においてタイヤ周方向に隣接する前記第1凸部の間に設けられた複数の第2凸部と、前記第1凸部と前記第2凸部との間に形成された第1凹溝とを備え、
前記第1凸部は、頂面の面積が前記第2凸部より広く、前記バットレス部からの突出高さが前記第2凸部より高く、
前記第2凸部は、頂面から陥没する第2凹溝を備え、前記第2凹溝が前記第1凹溝と平行に設けられている空気入りタイヤ。 - 前記第1凸部は、タイヤ径方向に開口するノッチを備える請求項1に記載の空気入りタイヤ。
- 前記第1凸部及び前記第2凸部において最もタイヤ径方向外側に位置する箇所を通る外側円と、最もタイヤ径方向内側に位置する箇所を通る内側円とで挟まれた領域を、タイヤ径方向の長さが等しくなるように内側領域と外側領域に2分割したときに、前記内側領域の面積に対する前記内側領域に位置する前記第1凸部及び前記第2凸部の頂面の面積の合計の比率と、前記外側領域の面積に対する前記外側領域に位置する前記第1凸部及び前記第2凸部の頂面の面積の合計の比率との差が、15%以下である請求項1又は2に記載の空気入りタイヤ。
- 前記第1凸部及び前記第2凸部において最もタイヤ径方向外側に位置する箇所を通る外側円と、最もタイヤ径方向内側に位置する箇所を通る内側円とで挟まれた領域の面積に対する前記第1凸部及び前記第2凸部の頂面の面積の合計の比率が50%以上である請求項1~3のいずれか1項に記載の空気入りタイヤ。
- 前記第1凸部は、タイヤ径方向外方に行くほど前記バットレス部からの突出高さが高くなる請求項1~4のいずれか1項に記載の空気入りタイヤ。
