PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2020/170537
Kind Code:
A1
Abstract:
This pneumatic tire is provided with fins 4A, 4B which are positioned on a side wall surface of blocks 3A, 3B and extend in a tire circumference direction. Moreover, a local plane X is defined so as to include ground terminals belonging to the first and the second blocks 3A, 3B, and a circular arc connecting opening end parts of three lug grooves 2 which divide the first and the second blocks 3A, 3B. At such time, at edge parts 31A, 31B of the blocks 3A, 3B in one circumference direction, the fins 4A, 4B of the first and the second blocks 3A, 3B extend a groove wall of the lug grooves 2 farther to the outside in a tire width direction than the plane X. Moreover, the amount by which the fins 4A, 4B protrude with respect to the plane X decreases gradually from the edge parts 31A, 31B of the blocks 3A, 3B in the one circumference direction towards edge parts 32A, 32B in the other circumference direction.
