Problems solved by technology

However, conventional tires do not take into account the lateral force generated by the blocks during acceleration and deceleration (hereinafter, sometimes simply referred to as "driving").
For example, there is a problem that when the lateral force acting on each block acts in the same direction, it is easy to cause the vehicle to drift when driving on sandy roads on gravel roads and roads on dry asphalt roads.

Embodiment Construction

[0028] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0029] figure 1 A developed view showing the tread portion 2 of the tire 1 according to one embodiment of the present invention is shown. The present invention can be used, for example, as various tires such as pneumatic tires for cars and trucks, and non-pneumatic tires that do not fill the inside of the tire with pressurized air. The tire 1 of this embodiment is an all-season tire for a four-wheel drive vehicle.

[0030] Such as figure 1 As shown, the tread portion 2 of the tire 1 is provided with a shoulder block 3 disposed on the tread edge Te side and a crown block 4 disposed axially inward of the shoulder block 3 . The tread portion 2 of the present embodiment is provided with grooves 5 extending between the shoulder blocks 3 , 3 , between the crown blocks 4 , 4 , and between the shoulder blocks 3 and the crown blocks 4 .

[0031] The shoulder block 3 of the present...

Abstract

The invention provides a tire capable of improving the sand road performance and the highway performance while maintaining the mud performance. The tire (1) comprises a tread portion (2) comprising shoulder pattern blocks (3) and crown pattern blocks (4). The shoulder pattern blocks (3) each have a ground contacting surface (3t) comprising a gently oblique portion (6) extending to the axial innerside of the tire from the tread edge (Te) side and a steeply oblique portion (7) connected with the gently oblique portion (6) and having a larger inclination angle with respect to the tire axial direction than the gently oblique portion (6). The crown pattern blocks (4) each have a ground contacting surface (4t) comprising a first oblique portion (10) inclined oppositely to the steeply oblique portion (7) and a second oblique portion (11) which is connected to the first oblique portion (10), opposite to the first oblique portion (10) and inclined toward the tread edge (Te) side. In a development view of the tread portion (2), long side directions of the steeply oblique portion (7) and the first oblique portion (10) intersect at an angle from 70 to 110 degrees.

Description

technical field [0001] The present invention relates to a pneumatic tire that improves sand performance and on-road performance while maintaining muddy performance. Background technique [0002] For all-season tires and M+S tires for uneven ground, for example, so-called mud performance that exhibits sufficient soil release properties on muddy roads is required. In order to improve the mud performance, a block tire having a plurality of blocks provided on the tread portion is used. However, conventional tires do not take into account the lateral force generated by the blocks during acceleration and deceleration during running (hereinafter, sometimes simply referred to as "driving"). For example, there is a problem that when the lateral force acting on each block acts in the same direction, the vehicle tends to drift when driving on sandy roads on gravel roads and roads on dry asphalt roads.
