Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2016/181940
Kind Code:
A1
Abstract:
In order to maintain good uniformity, increase downforce, and reduce air resistance, the present invention includes a plurality of protrusions (9) that: are provided in a range including a maximum tire width position (H) in a tire side section (S); and extend in a direction orthogonal to the tire radial direction. The plurality of protrusions (9) are provided having a space therebetween in the tire circumferential direction, pass through the rotation center (P), extend in the tire radial direction, and, when a first straight line (S1) and a second straight line (S2) each having different positions in the tire circumferential direction each traverse the protrusions (9), have a ratio of 0.8-1.2 between the total mass per unit length for protrusions (9) traversed by the first straight line (S1) and the total mass per unit length for protrusions (9) traversed by the second straight line (S2). The ratio between the total width (SW) and the outer diameter (OD) fulfills the relationship SW/OD ≤ 0.3.
