Title:
PNEUMATIC TIRE
Document Type and Number:
Japanese Patent JP2021138312
Kind Code:
A
Abstract:
To provide a pneumatic tire improved in uneven wear resistance by suppressing deformation of the tire with inner pressure variation, and suppressing deformation in the vicinity of a belt end.SOLUTION: A carcass line in the application of 10% of normal inner pressure is composed of a curve W positioned in a tread part 1 and curved so as to project toward the outside in a tire radial direction, and a curve S positioned in a side wall part 2 and curved so as to project toward the outside in a tire width direction. An inclination θW of the curve W and an inclination θS of the curve S in a connection point V in which the curve W and the curve S are connected satisfy a relation of |θW-θS|≥5°, and the connection point V is arranged in the inside in the tire width direction of a point A corresponding to an outer end point of an effective width of a pair of cross belts.SELECTED DRAWING: Figure 3
