To suppress an adhesion amount of muds adhered to a tread part.SOLUTION: A tire 10 comprises: a center rib 30 which is provided on an outer peripheral surface 18A of a tread part 18, and extends in a tire circumferential direction with a width W1 on both sides of an equator CL of the tire 10; and lugs 40 which are provided on the outer peripheral surface 18A of the tread part 18, and are respectively arranged on width direction both sides of the center rib 30. The center rib 30 has a width being 30% or more and 50% or less of a tread width TW of the tread part 18. The lug 40 is formed at an angle of 20° or more and 50° or less on an opposite side in a tire rotation direction C with respect to a tire rotary shaft direction within a range in which the lugs are respectively arranged at least 25% of the tread width from the equator CL. The sum of areas of ground planes 42 in all lugs 40 is so made as to be 4.5% or more and 15% or less of an area when the tread part 18 is developed in a plane and viewed in a plan view.SELECTED DRAWING: Figure 2

    【課題】トレッド部に付着する泥土の付着量を抑制することを目的とする。【解決手段】タイヤ10は、トレッド部18の外周面18Aに設けられ、タイヤ10の赤道CLの両側に幅W1を有してタイヤ周方向に延在する中央リブ30と、トレッド部18の外周面18Aに設けられ、中央リブ30の幅方向両側にそれぞれ配置されるラグ40と、を備え、中央リブ30は、トレッド部18のトレッド幅TWの30%以上50%以下の幅を有し、ラグ40は、赤道CLからそれぞれトレッド幅の25%以上に配置される範囲にて、タイヤ回転軸方向に対して、タイヤ回転方向Cの反対側に20°以上50°以下の角度で形成され、すべてのラグ40における接地面42の面積の合計は、トレッド部18を平面的に展開して平面視したときの面積の4.5%以上15%以下とされたものである。【選択図】図2
