、偏摩耗などを有効に防止するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a protruding element of a pneumatic tire that improves the rut-crossing performance of a tire with a block pattern.
In particular, it is applied to heavy-duty tires, making it sufficiently easy to traverse deep ruts, and effectively preventing premature wear and uneven wear of the protruding elements.

とができる。(Prior art) Improvements in the rut-crossing performance of tires with blocks in the shoulder area are achieved by - For boat fishing, cutting is provided in the shoulder block to reduce the block rigidity; Accordingly, the block, especially its outer side wall in the tire width direction, can reduce the reaction force received from the wall surface of the rut, making it easier to get over the rut.

するという問題があった。(Problem to be Solved by the Invention) However, in this prior art, when cuts are provided only at the outer end portion of each block in the tire width direction, the blocks suffer from uneven wear called heel-and-toe wear. Furthermore, if each block is provided with a cut that spans its entire width, the wear resistance of the block will be reduced, and the lateral force generated when a slip angle is applied to the tire will be reduced. There was a problem in that this caused a decrease in maneuverability.
この発明は、従来技術のこれらの問題を有利に解決する

イヤの突起要素を提供するものである。The present invention advantageously solves these problems of the prior art and significantly improves rut-crossing performance without significantly preventing premature wear and uneven wear and without resulting in a reduction in lateral force. The present invention provides a protrusion element for a pneumatic tire that can be used.

。(Means for Solving the Problems) The protrusion element of the pneumatic tire of the present invention is particularly characterized by a block-shaped protrusion disposed on the shoulder portion of the tire.
On the side wall located on the outside in the width direction of the tire, there is a 1.
It is provided with a sloped portion that protrudes at an angle of 25° to 25°.

十分容易ならしめることができる。(Function) According to this protrusion element, when a tire transferring in a rut crosses the rut, the protrusion width is included in the side wall located on the outside in the tire width direction of the protrusion element, and the protrusion width is reduced to the treading side. The slope portion that gradually increases from the rut toward the kicking side functions to increase the contact area between the rut side wall surface and the protrusion element, thereby increasing the frictional force between the rut side wall surface and the tire. As a result, it is possible to sufficiently easily cross over the side wall surface.

ルアンドトウ摩耗の発生が有効に防止される。In addition, the side wall also functions to increase the rigidity of the kicking part of the protrusion element due to the action of the sloped part, so deformation of the kicking part when kicking off the road surface is suppressed, and heel-and-toe wear is suppressed. occurrence is effectively prevented.
しかも、この突起要素では、その踏面部に切込みを全く

ことができる。Moreover, since this projecting element does not form any incisions in its tread portion, it is also possible to advantageously prevent its early wear and the reduction in lateral forces that occur during cornering.
ところで、上述したわだち乗越し性能は、前述した傾斜
部分の、タイヤ幅方向外側への迫出角度をl°〜25°
、好ましくは2°〜15゛の範囲内の角度とすることに
よって、とくに有効に向上されることになる。By the way, the above-mentioned rut-crossing performance is determined by adjusting the protrusion angle of the above-mentioned slope part to the outside in the tire width direction from 1° to 25°.
, preferably within the range of 2° to 15°, the improvement is particularly effective.

し性能が逆に低下する。In other words, if the protruding angle is less than 1°, the rut-crossing performance will hardly improve, and if it exceeds 25°, the stepping-side portion of the protruding element will no longer come into contact with the rut side wall surface, and the rut-crossing performance will be adversely affected. decreases to
