农业机械用轮胎
摘要：
本发明的目的是在不降低田地中的牵引性能的情况下减少在铺面道路上高速行驶过程中的轮胎振动。一种农业机械用轮胎包括：横向花纹块（12），其布置于胎面部（16）且沿轮胎周向在轮胎赤道面（CL）的两侧交替地形成；以及中央肋（14），其在胎面部（16）的轮胎宽度方向中央部处沿轮胎周向延伸且横向花纹块（12）的在轮胎赤道面（CL）侧的端部被一体地连接到该中央肋（14），当中央肋（14）的从在中央肋（14）和端部之间的连接部（18）至轮胎赤道面（CL）的轮胎宽度方向长度被当作第一肋宽度（w1）并且中央肋（14）的从中央肋（14）的隔着轮胎赤道面（CL）位于连接部（18）的轮胎宽度方向相反侧的端缘至轮胎赤道面（CL）的轮胎宽度方向长度被当作第二肋宽度（w2）时，第一肋宽度（w1）被构造成大于第二肋宽度（w2）。
摘要（英）：

The purpose of the present invention is to reduce tire vibration during high-speed travel on paved roads without decreasing traction performance in farm fields. The present invention has: lug blocks (12) provided to a tread part (16) and formed in alternating fashion on both sides of a tire equator (CL) in the circumferential direction of the tire; and a central rib (14) extending in the circumferential direction of the tire at the center in the tire-width direction of the tread part (16), in which end parts of the lug blocks (12) on the tire equator (CL) sides thereof are integrally connected, and which is configured such that when the length in the tire-width direction to the tire equator (CL) from connecting parts (18) with the end parts is designated as a first rib width (w1), and the length in the tire-width direction to the tire equator (CL) from edges of the connecting parts (18) on either side of the tire equator (CL) in the opposite tire-width direction is designated as a second rib width (w2), the first rib width (w1) is greater than the second rib width (w2).
