Document Type and Number:
WIPO Patent Application WO/2014/129572
Kind Code:
A1
Abstract:
This pneumatic tire (1) has: a tread section; tire side sections; and a carcass section that extends over the tread section, the tire side sections, and bead sections. The carcass section has a carcass body section and folded sections each folded around a bead core. A circumferential recessed section, which is recessed inward in the tire width direction and extends in the tire circumferential direction, is formed on the outer surface of the tire side section, and turbulence-generating protrusions are provided on the circumferential recessed section. In a cross-section of the tire, wherein the distance between the inner surface of the carcass body section and a rim-separation point where the inner surface comes into contact with a normal rim is defined as a tire reference thickness, and the distance between the inner surface of the folded section and the tire outer surface at the circumferential recessed section is defined as a tire thickness, the multiple turbulence-generating protrusions are provided in an area where the tire thickness is between 20% and 60% of the tire reference thickness.
