Abstract
Durability of a pneumatic tire is enhanced by effectively promoting heat radiation by air cooling. A plural of projections are comprised on a surface of a tire side portion. The projection comprises a front side surface which is a side surface of a tire rotational direction side and an outer end surface which is a side surface of a tire outer radial direction side. The front edge portion intersects a straight line extending in a tire radial direction as viewed in a tire wide direction. A tip angle made by the top surface and the front side surface on the edge portion of the projection is equal to or less than 100°. The outer end surface comprises a projection having an inclination side surface which is inclined in a tire rotating rivers direction toward a tire outer radial direction.
