Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2014/136523
Kind Code:
A1
Abstract:
In the present invention, the amount of protrusion when internal pressure has been increased from an internal pressure state of 0.05 times a normal internal pressure (P) to an internal pressure state of the normal internal pressure (P) is Da mm at point Pa, Dh mm at point Ph, Dd mm at point Pd, and De mm at point Pe. The protrusion total (Fa) (((Dd+De)/W)×100) at a side wall (6) satisfies formulae (2) and (3) with a flattening rate of A, and the protrusion difference (Gs) (((Da-Dh)/W)×100) of a tread (4) satisfies formulae (5) and (6). 0.02626×A-1.8615 < Fa (2) Fa < 0.02626×A-0.6615 (3) -0.010819×A-0.084658 < Gs (5) Gs < -0.010819×A+0.6713 (6)
