<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire for a heavy load, which has excellent fuel consumption performance and drainage performance by properly partitioning a land part, positioned in a central area of a tread of a tread part, with various types of thin grooves.SOLUTION: In a pneumatic tire for a heavy load, a land part 7 positioned in an area of a tread of a tread part is partitioned with thin grooves (6a-6c), in the area of the tread of the tread part with a width equivalent to 40-65% of a tread width TW, centering on a tire equator E. When the tire is brought into contact with ground, all openings of the thin grooves (6a-6c) arranged in the area of the tread of the tread part are closed.</p> |
