Abstract
【解決手段】周方向に隣接配置されたブロック群23においてブロック22の幅方向側壁24同士を前記ブロック22の配設ピッチPの 1/3〜 1/2倍に相当する距離Lだけ細溝19に沿ってずらしたので、周方向に隣接するブロック22では最大膨出部が細溝19に沿って大きくずれ、これにより、細溝19、交差細溝21において閉鎖されない空間が増加し、しかも、各ブロック22の開口端エッジ近傍に接地圧の高い部位が残るため、ウエット性能が向上する。この際、細溝19、交差細溝21の溝幅を広くする必要はないため、転がり抵抗の悪化を阻止することができる。
【選択図】図1
Description
図1、2において、11はトラック・バスや乗用車に装着される空気入りラジアルタイヤであり、この空気入りタイヤ11は内部にエア、窒素ガス等が充填された状態で使用される。この空気入りタイヤ11は半径方向外端部に走行時に接地するトレッド部12を有し、このトレッド部12の外周面(踏面)にはタイヤ赤道Sに沿ってジグザグに屈曲しながら連続して延びる複数本の主溝13が形成されているが、これら主溝13は幅広であるため、接地時においても閉じることはない。ここで、前記主溝13はタイヤ赤道(トレッドセンター)Sの両側のトレッド部12にそれぞれ少なくとも1本ずつ、この実施形態では2本ずつ合計4本形成されており、この結果、タイヤ赤道Sに最も近接する2本の内側主溝13a間にはタイヤ赤道S上を延びる1本の近接陸部14が、また、前記内側主溝13aと、該内側主溝13aより幅方向外側にそれぞれ配置された2本の外側主溝13bとの間には2本の中間陸部15が、さらに、前記外側主溝13bとトレッド端Eとの間には2本の外側陸部16が画成され、これにより、前記トレッド部12にはタイヤ赤道Sに沿って延びる複数本、ここでは5本の陸部が形成される。なお、この発明においては、前記主溝はタイヤ赤道Sの両側のトレッド部12に1本ずつ、あるいは3本ずつ、合計2本、あるいは6本設置してもよく、また、前述した主溝の他にタイヤ赤道S上に1本の主溝を追加してもよく、さらに、前述の主溝は真っ直ぐに延びていてもよい。

Claims (6)
- タイヤ赤道Sの両側のトレッド部に少なくとも1本の主溝をそれぞれ形成することで複数本の陸部を形成するとともに、少なくともいずれか1本の前記陸部に幅方向に延び接地時に閉じる細溝および前記細溝に交差し接地時に閉じる交差細溝を形成することで、該陸部に前記細溝に沿って整列配置された複数のブロックからなるブロック群を周方向に繰り返し配置するようにした空気入りタイヤにおいて、周方向に隣接配置されたブロック群においてブロックの幅方向側壁同士を前記ブロックの配設ピッチPの 1/3〜 1/2倍に相当する距離Lだけ細溝に沿ってずらすようにしたことを特徴とする空気入りタイヤ。
- タイヤ赤道Sに最も近接する近接陸部に前記細溝および交差細溝を形成するようにした請求項1記載の空気入りタイヤ。
- 前記陸部に形成された細溝、交差細溝の溝深さDを、該陸部にその幅方向外側において接する主溝の溝深さFより大とした請求項1または2記載の空気入りタイヤ。
- 前記近接陸部以外の陸部にも細溝、交差細溝を形成するとともに、該近接陸部に形成されている細溝、交差細溝の溝深さHを、近接陸部以外の陸部に形成されている細溝、交差細溝の溝深さJより大とした請求項2記載の空気入りタイヤ。
- 前記陸部に形成されている細溝、交差細溝のうち、タイヤ赤道Sに近接する近接部に位置する細溝、交差細溝の溝深さQを、タイヤ赤道Sから離隔する離隔部に位置する細溝、交差細溝の溝深さRより大とした請求項1記載の空気入りタイヤ。
- 前記細溝はタイヤ子午線Gに対して傾斜している請求項1〜5のいずれか一項に記載の空気入りタイヤ。
