Claims

[Scope of Claim for Utility Model Registration] (1) A pneumatic lug tire in which a large number of lugs are arranged on the outer peripheral surface of the tread portion of the tire in a figure-eight pattern from near the tire's equator plane toward the outside, alternating left and right. The two right and left lugs that are sandwiched and adjacent to each other have an inner end portion that is spaced from the tire equatorial plane, an inner end surface that is orthogonal to the tire equatorial plane, and a portion that intersects with the same radial plane that includes the tire rotation axis. Pneumatic lug tires. (2) The pneumatic lug tire according to claim 1, wherein the width of the inner end surface is in the range of 8 to 15% of the total width of the lug on the outer peripheral surface of the tread portion.
