Abstract
It is an object to reduce tire vibration during high-speed travel on paved roads without lowering traction performance in fields. An agricultural machine tire includes: lug blocks disposed in a tread portion and formed alternately on both sides of a tire equatorial plane in a tire circumferential direction; and a central rib extending in the tire circumferential direction and to which end portions of the lug blocks on the tire equatorial plane side are integrally connected, and when a tire width length of the central rib from connecting portions to the tire equatorial plane is taken as a first rib width and a tire width length of the central rib from end edges of the central rib from the connecting portions across the tire equatorial plane to the tire equatorial plane is a second rib width, the width of the first rib is greater than the second rib.
