The rubber composition contains a natural rubber as a base polymer. The rubber composition contains sulfur. The mid layer 10 is formed by crosslinking a rubber composition. This rubber composition includes butadiene as a principal component of the base polymer. The center 8 has an inside diameter of 2 mm or greater and 13 mm or less. The center 8 has an outside diameter of 5 mm or greater and 15 mm or less. The center 8 has a surface JIS-C hardness H2 of 25 or greater and 55 or less. A difference (H4−H3) between a surface JIS-C hardness H4 of the mid layer 10 and a JIS-C hardness H3 of an innermost part of the mid layer is equal to or greater than 10.
