Title (EN) PNEUMATIC TIRE FOR AGRICULTURAL MACHINERY
(FR) PNEU POUR MACHINES AGRICOLES
(JA) 農業機械用空気入りタイヤ
Abstract:
(EN) In a tire side portion (38) of a pneumatic tire (10) for agricultural machinery, a recess portion (56) is formed. Rigidity is decreased where the recess portion (56) is formed in the tire side portion (38) so that a radially outer portion of the tire can be caused to fall outside in a tire width direction starting from the recess portion (56) without decreasing the internal pressure. Thus, the ground-contacting width of a tread portion (32) can be increased. Because it is not necessary to deliberately decrease the internal pressure so as to decrease ground-contacting pressure, a bead portion (12) does not fall more than is necessary, and the durability of the bead portion (12) is not decreased.
(FR) L'invention concerne un pneu (10) pour machines agricoles, caractérisé en ce qu'une partie renfoncée (56) est formée dans une partie latérale (38) de pneu. La rigidité est diminuée là où la partie renfoncée (56) est formée dans la partie latérale (38) de pneu, de sorte qu'une partie radialement externe du pneu puisse être amenée à tomber à l'extérieur d'une direction de largeur du pneu en partant de la partie renfoncée (56), sans diminuer la pression interne. Ainsi, la largeur de contact avec le sol d'une partie de bande de roulement (32) peut être accrue. Parce qu'il n'est pas nécessaire de diminuer volontairement la pression interne de façon à diminuer la pression de contact avec le sol, une partie de talon (12) ne tombe pas plus qu'il n'est nécessaire et la durabilité de la partie de talon (12) n'est pas diminuée.
(JA)  農業機械用空気入りタイヤ(10)のタイヤサイド部(38)に凹部(56)を形成する。タイヤサイド部(38)の凹部(56)の形成されている部分の剛性が低減され、内圧を低減せずとも凹部(56)を起点としてタイヤ径方向外側部分をタイヤ幅方向外側へ倒れ込ませることができ、これによってトレッド部(32)の接地幅を拡大することができる。接地圧を低減するために故意に内圧を低下させる必要がないので、ビード部(12)が必要以上に倒れ込むことは無く、ビード部(12)の耐久性を低下させることが無い。
