Definitions
- the present invention relates to a pneumatic tire.
- Patent Document 1 A manufacturing method in which a tread rubber cap rubber layer is raised to reduce the weight of the tire is disclosed (see Patent Document 1).
- a tire case formed of a carcass layer or the like is curved inward in the tire radial direction.
- a belt layer that reinforces the carcass layer is laminated on the inner side in the tire radial direction of the tread portion, and an end portion in the tire width direction of the belt layer is located on the inner side in the tire radial direction of the shoulder portion.
- the belt layer swells outward in the tire radial direction. Therefore, securing a rubber gauge at the tread portion at the end in the tire width direction of the belt layer is important for ensuring durability.
- the present invention aims to reduce the weight of the tire while maintaining the wet performance in consideration of the above facts.
- the first aspect of the present invention is the tire width of the belt layer formed on the outermost shoulder portion of the tread portion in the tire width direction, extending in a direction intersecting the tire circumferential direction, and positioned on the inner side of the tread portion in the tire radial direction.
- the reason why the bottom raised portion of the bottom of the lug groove is arranged corresponding to the outer end portion (belt end) in the tire width direction of the belt layer is that the belt end is generally located in this region. This is because it is difficult to secure a gauge from the treat rubber at the belt end to the groove bottom of the lug groove when trying to suppress the rubber gauge of the entire tread portion.
- the lug groove of the shoulder portion is positioned on the outer side in the tire radial direction of the belt end, and the bottom raised portion of the groove bottom of the lug groove is at an appropriate position corresponding to the belt end. Since it is set, even if the rubber gauge of the entire tread portion is suppressed, the volume of the lug groove can be maintained, and a rubber gauge between the groove bottom of the lug groove and the belt end can be secured. For this reason, a tire can be reduced in weight, maintaining wet performance.

It is provided at the groove bottom of the lug groove in a region of 9 TW / 2 or more, and is raised from the tire equatorial plane to the outer side in the tire width direction compared to the groove bottom in a region of less than 0.9 TW / 2.
- the reason that the bottom raised portion of the groove bottom of the lug groove is provided in the region of 0.9 TW / 2 or more on the outer side in the tire width direction from the tire equatorial plane is that the belt end is generally located in this region, This is because if it is attempted to suppress the rubber gauge of the entire tread portion, it is difficult to secure a gauge from the treat rubber at the end portion to the groove bottom of the lug groove.
- the bottom raised portion of the groove bottom of the lug groove is set at a more appropriate position corresponding to the belt end, so even if the rubber gauge of the entire tread portion is suppressed, The volume of the lug groove can be maintained, and a rubber gauge between the lug groove bottom and the belt end can be secured. For this reason, a tire can be reduced in weight, maintaining wet performance.
- the outermost point in the tire radial direction of the bottom raised portion is 0.9 TW / 2 on the outer side in the tire width direction from the tire equatorial plane. As described above, it is located in an area of 1.1 TW / 2 or less.
- the outermost point in the tire radial direction of the bottom raised portion is provided in the region of 0.9 TW / 2 or more and TW / 2 or less on the outer side in the tire width direction from the tire equatorial plane. If it is below, the volume of the lug groove in the tire ground contact surface will be reduced and the drainage will be deteriorated. This is because it is difficult to secure a gauge from the treat rubber at the belt end to the groove bottom of the lug groove.
- the volume of the bottom raised portion is suppressed to the necessary minimum, and the volume of the lug groove is reduced. More can be secured. For this reason, wet performance can be maintained at a higher level.

- the outermost point 36A in the tire radial direction of the bottom raised portion 36 is provided in the region of 1.1 TW / 2 or less on the outer side in the tire width direction from the tire equatorial plane CL. This is because when the portion 36 and the belt end 18A are displaced and the rubber gauge of the entire tread portion 20 is suppressed, it is difficult to secure a gauge from the treat rubber at the belt end 18A to the groove bottom of the lug groove 34. Secondly, the lug groove 34 becomes extremely shallow at the outer end portion of the lug groove 34 in the tire width direction, leading to a decrease in drainage and a deterioration in design.

In addition, the rubber gauge D6 from the treat rubber at the belt end 18A to the groove bottom of the lug groove 34 can be sufficiently secured.
- the rubber gauge D6 may be insufficient.
- the groove bottom 34A of the lug groove 34 is raised as a whole, the groove volume is greatly reduced. Therefore, by providing a bottom raised portion 36 at a position corresponding to the belt end 18A in the groove bottom 34A of the lug groove 34, the rubber gauge D6 at the belt end 18A is secured and the decrease in the groove volume is suppressed. Yes.
- the volume of the bottom raised portion 36 is suppressed to the necessary minimum, and a larger volume of the lug groove 34 is secured. Can do. For this reason, the weight of the tire can be reduced while maintaining the wet performance at a higher level.
- the number of circumferential main grooves is not limited to this.
- the land portion of the tread portion 20 the central region land portion 30 and the shoulder portion 32 are described, but the configuration of the land portion other than the shoulder portion 32 is arbitrary.
