Abstract
Description
本発明の空気入りタイヤは、タイヤサイド部の外表面に、文字、記号又は図形を有する1以上の標章を有する標章部を備える空気入りタイヤであって、タイヤ側面視において、前記標章部は、湾曲形状を有しており、前記標章部の標章には、直線状のリッジが配置されており、前記標章部におけるリッジは、全て平行であること、を特徴とする。
なお、タイヤが複数の標章部を有する場合には、本発明では、少なくとも一つの標章部の標章に、直線状のリッジが配置されていればよい。言い換えると、少なくとも一つの標章部の標章に、直線状のリッジが配置されていれば、他の標章部には、放射状のリッジが配置されていてもよい。直線状のリッジが配置された標章部と、放射状のリッジが配置された標章部とを組み合わせると、標章部の視認性をより顕著にすることが可能となる。また、放射リッジは、平行リッジと比較して、タイヤ径方向に対する角度の変化が小さいため、リッジのクラック耐久性を標章部内で均一に近づけることが可能となる。特に、放射リッジの各リッジの交点(放射リッジの中心)が、タイヤ回転軸と一致する場合には、タイヤ径方向に対するリッジの角度が同一となる。そのため、各リッジのクラック耐久性をより均一に近付けることが可能となる。なお、直線状のリッジが配置された標章部と、放射状のリッジが配置された標章部との両方を有する場合には、直線状のリッジが配置された標章部と、放射状のリッジが配置された標章部とは、タイヤ周方向で見たときに重複しない位置に配置されていることが製造上の観点から好ましい。
以下、本実施形態のタイヤの作用効果について説明する。
よって、本実施形態の空気入りタイヤでは、標章部17の視認性にバラツキが生じることを抑制して、標章部17の視認性を高めることができる。
実施例1~6及び比較例1~2にかかるタイヤについて、リム組み及び内圧充填後のタイヤをローラー式回転台に乗せタイヤを回転させ、2m離れて立つ看者により標章部の視認性について目視により判断した。なお、評価結果は、30人の看者が目視によって3段階に評価を行ったものである。標章部の両端及び中央がいずれもはっきりと視認できた場合に「◎」、標章部の両端または中央のいずれかがはっきりと視認できた場合に「○」、標章部の両端及び中央のいずれもがはっきりと視認できない場合に「△」とした。表中の評価は、30人の看者の評価結果のうち、最も評価結果の多かった評価を示している。
実施例1~6及び比較例1~2にかかるタイヤについて、ドラム速度60km/hで10000kmに亘って615kg(JATMA最大荷重)のドラム荷重を負荷するドラム試験(10000km試験)を実施した。また、20000kmに亘るドラム試験(20000km試験)及び30000kmに亘るドラム試験(30000km試験)を、他は10000km試験と同一の条件で実施した。ドラム荷重負荷後に、周方向クラックの有無を、10000km試験、20000km試験および30000km試験別に目視により判別することにより、耐クラック性を評価した。10000km試験において周方向クラックが発生しないが20000km試験において周方向クラックが発生したものを「△」、20000km試験において周方向クラックが発生しないが30000km試験においてクラックが発生したものを「○」、30000km試験において周方向クラックが発生しないものを「◎」とした。
