重荷重用タイヤ
Document Type and Number:
Japanese Patent JP6959850
Kind Code:
B2
Abstract:
A heavy duty tire 10 includes a recess portion 34, a diameter-direction air entry and exit promotion portion 38 and an air-catching wall portion 44. The recess portion 34 is formed in a buttress portion 26 and opens to a tire outer side. The diameter-direction air entry and exit promotion portion 38 is disposed at one side of a floor portion 40 in a tire diameter direction and includes a slope 52 that, from the floor portion 40 toward a tire surface, gradually decreases in depth from the tire surface. The diameter-direction air entry and exit promotion portion 38 facilitates access of air toward the floor portion. The air-catching wall portion 44 is disposed at the opposite side of the floor portion 40 from the diameter-direction air entry and exit promotion portion 38. The air-catching wall portion 44 has a greater angle relative to the tire surface than the slope.
