空気入りタイヤ
Document Type and Number:
Japanese Patent JP6724451
Kind Code:
B2
Abstract:
[Problem to be solved] To provide a pneumatic tire that can improve wear resistance of shoulder land portions while suppressing sideslip on snow and ice. [Solution] By providing shoulder main grooves 3 and a center main groove 4 in a tread part 2, the tread part 2 is divided into shoulder land portions 7 and middle land portions 8. A ratio (W1/W2) of a width (W1) of each of the shoulder land portions 7 to a width (W2) of each of the middle land portions 8 is 1.6 - 2.4. In each of the shoulder land portions 7, on a shoulder main groove 3 side, a shoulder narrow groove 10 that continuously extends in a tire circumferential direction with a groove width smaller than that of each of the shoulder main grooves 3 is provided. A first camber amount (C1), which is a tire radial direction distance between a tire equator position and a tread edge (Te) in a tread profile in a tire cross section that includes a tire rotation axis in a normal state, is 5.3% - 6.5% of a tread ground contact width (TW).
