Summary: | PROBLEM TO BE SOLVED: To provide a pneumatic tire for heavy load capable of suppressing uneven wear on the tread edge side while improving water discharging property on the tire equator side.SOLUTION: A pneumatic tire for heavy load has a plurality of main grooves 3 and a plurality of lateral grooves provided on a tread part 2 and, thereby, allows a plurality of blocks to be partitioned. Therein, the main grooves 3 contain a pair of crown main grooves 4 and a pair of shoulder main grooves 5, all of the lateral grooves contain a plurality of crown lateral grooves 11 which are inclined with respect to the tire axial direction and partition a crown block 15, a plurality of middle lateral grooves 12 which partition a middle block 16 and a plurality of shoulder lateral grooves 13 which partition a shoulder block 17 and an inclination angle β2 of the middle lateral grooves 12 is smaller than an inclination angle β1 of the crown lateral grooves 11 and is larger than an inclination angle β1 of the shoulder lateral grooves 11.SELECTED DRAWING: Figure 2
【課題】タイヤ赤道側での排水性を高めつつ、トレッド端側での偏摩耗を抑制しうる重荷重用空気入りタイヤを提供する。【解決手段】トレッド部2に、複数本の主溝3と、複数本の横溝とが設けられることにより、複数のブロックが区分された重荷重用空気入りタイヤであって、主溝3は、一対のクラウン主溝4と、一対のショルダー主溝5とを含み、横溝は、いずれもタイヤ軸方向に対して傾斜し、かつ、クラウンブロック15を区分する複数本のクラウン横溝11と、ミドルブロック16を区分する複数本のミドル横溝12と、ショルダーブロック17を区分する複数本のショルダー横溝13とを含み、ミドル横溝12の傾斜角度β2は、クラウン横溝11の傾斜角度β1よりも小さく、かつ、ショルダー横溝11の傾斜角度β1よりも大きい。【選択図】図2 |
