Description
サイド部に設けられ、タイヤ周方向に延びるショルダー主溝、及び、タイヤ幅方向に延びるショルダー横溝によって区画され、タイヤ周方向に並設される複数のショルダーブロックと、
前記サイド部に設けられ、前記ショルダーブロックに沿ってタイヤ周方向に延びる補助リブと、
前記サイド部に設けられ、前記補助リブから前記ショルダーブロックに向かって尖った先端部を有する突起と、
を備え、
前記突起は、前記ショルダーブロックに向かって斜めに延び、
前記ショルダーブロックの中心線は、タイヤ幅方向に延びる直線に対して傾斜し、
前記突起の中心線は、タイヤ幅方向に延びる直線に対して傾斜し、
前記ショルダーブロックと前記突起の中心線は、タイヤ幅方向に対する傾斜方向が逆向きである。
サイド部に設けられ、タイヤ周方向に延びるショルダー主溝、及び、タイヤ幅方向に延びるショルダー横溝によって区画され、タイヤ周方向に並設される複数のショルダーブロックと、
前記サイド部に設けられ、前記ショルダーブロックに沿ってタイヤ周方向に延びる補助リブと、
前記サイド部に設けられ、前記補助リブから前記ショルダーブロックに向かって尖った先端部を有する突起と、
を備え、
前記突起は、前記ショルダーブロックに向かって斜めに延び、
前記ショルダーブロックは、前記突起の各突条部の先端部が位置する鋸歯状の切欠きを形成されている。
図1は、第1実施形態に係る空気入りタイヤの斜視図である。この空気入りタイヤは、図示しないが、一対のビードコア間にカーカスを掛け渡し、カーカスの中間部の外周側にベルトを巻き付けて補強し、さらにタイヤ外径側にトレッド部6を配置した構成である。
(1)突起15がショルダーブロック5と補助リブ14を補強して剛性を高め、サイド部7の縦方向の撓み量を抑制できる。
(2)特に、突起15を2つの突条部16,17で形成し、ショルダーブロック5に食い込ませるように構成しているので、サイド部7の縦方向の撓み量をより一層抑制できる。
(3)突起15が斜めに形成することにより、タイヤ周方向での突起15の占有スペースを大きくして耐外傷性能を高めることができる。
(4)突起15はショルダー横溝4内には大きく突出しないので、ショルダー横溝4を利用した排水性を悪化させることがない。
図4は、第2実施形態に係る空気入りタイヤのトレッド部6の展開図である。センターリブ3の構成は前記第1実施形態とほぼ同じである。ショルダーブロック5は、タイヤ周方向には完全には区画されておらず、部分的につながった構成となっている。ショルダーブロック5には、ショルダー主溝2からタイヤ幅方向外側に延び、途中でほぼ直角に折れ曲がったノッチ19が形成されている。また、ショルダー主溝2とは反対側の端部には、タイヤ周方向に所定間隔で切欠き20が形成されている。切欠き20は、第1傾斜部20aと第2傾斜部20bとで構成される三角形状(鋸歯状)である。
