Claims (5)
- トレッド部にタイヤ周方向に沿って延在する少なくとも3本の周方向溝により、タイヤ周方向に沿って延在する少なくとも4本のリブが区画形成される空気入りタイヤにおいて、
タイヤ赤道面を挟んでタイヤ幅方向の一側に配置される前記リブと、他側に配置される前記リブとの少なくとも2本の前記リブは、子午断面にてトレッド面の輪郭線よりもタイヤ径方向外側に突出しており、その突出量がタイヤ幅方向の一側の前記リブに対して他側の前記リブが順次小さく形成され、
前記トレッド部のトレッド面をなすキャップトレッドが種類の異なるコンパウンドで構成されており、当該コンパウンドの60℃における損失正接tanδについて、突出量が最大の前記リブの領域に対して突出量が最小の前記リブの領域が小さいことを特徴とする空気入りタイヤ。 - 前記輪郭線からの前記リブの突出量は、0.05mm以上2.0mm以下であることを特徴とする請求項1に記載の空気入りタイヤ。
- 突出量が最大の前記リブの領域のコンパウンドの60℃における損失正接tanδが0.25以上0.4以下であり、突出量が最小の前記リブの領域のコンパウンドの60℃における損失正接tanδが0.2以上0.33以下であることを特徴とする請求項1または2に記載の空気入りタイヤ。
- 車両装着時での車両内外の向きが指定されており、前記リブの突出量は、車両外側から車両内側に向けて順次小さく形成され、前記コンパウンドの60℃における損失正接tanδは、車両外側よりも車両内側が小さいことを特徴とする請求項1〜3のいずれか一つに記載の空気入りタイヤ。
- 前記輪郭線から突出する前記リブは、前記周方向溝を間において隣接して設けられており、当該隣接する各前記リブの突出量の差が0.1mm以上0.8mm以下であることを特徴とする請求項1〜4のいずれか一つに記載の空気入りタイヤ。
