Definitions
- Patent Document 2 Japanese Patent Laid-Open No. 2001-225608
- the lug angle (angle formed by the lug groove with respect to the tire rotation direction) ex of the kicking end 94 near 1Z4 point Q is different on both sides of the tire equatorial plane CL.
- the rotation direction as the positive axis, in FIG. 8, ⁇ > 90 ° on the right side of the plane of the tire equator CL, and a ⁇ 90 ° on the left side of the plane of the tire equator CL.
- the present inventor studied that the lug angle ex on the kicking side near the 1Z4 point should be 90 ° or less regardless of the direction of rotation of the tire, repeated experiments, and completed the present invention. It came to do.
- a compressive force acts toward the tire equatorial plane CL near the center of the tread.
- the tread edge means that the pneumatic tire is JATMA YEAR BOOK (2002 version, Japan Mounted on a standard rim specified in the Vehicle Tire Association Standard) and applicable size in JATMA YEAR BOO K 'Maximum load capacity in the ply rating (internal pressure load capacity corresponding to the bold load in the table)
- JATMA YEAR BOOK 2002 version, Japan Mounted on a standard rim specified in the Vehicle Tire Association Standard
- JATMA YEAR BOO K 'Maximum load capacity in the ply rating internal pressure load capacity corresponding to the bold load in the table
- the tread surface portion is a portion of the tread portion that is sandwiched between tread ends on both sides in the tire width direction.
- the width of the widthwise narrow groove is less than 1% of the tread width dimension, the durability of the mold bone (or blade (metal plate)) for forming the widthwise narrow groove decreases. It is not preferable.
- the present invention has the above-described configuration, a pneumatic tire suitable for construction vehicles and preventing one-side uneven wear is realized.
- FIG. 6 is a partial plan view showing a lug groove pattern within a tread width in a conventional pneumatic tire.
- FIG. 13 is a plan view of a tread of a pneumatic tire according to a conventional example used in the test.
- the tire temperature on the tire equatorial plane CL side can be made lower than in the first embodiment. Further, since the trapezoidal block portion 32 is formed across the 1/4 point Q, wear on the kicking side of the 1Z4 point Q can be suppressed.
- the present inventor has a pneumatic tire in which the tire size is 400 OR57 and the block portion 82 in the vicinity of 1Z4 point Q is rectangular when viewed from the tire tread side force (conventional tire)
- a performance test was conducted using the pneumatic tire of Example 1 (see Fig. 6).
- the number of pitches of the lug grooves 90 of the pneumatic tire of Conventional Example 2 is 36, and all the angles 0 formed by the lug grooves 90 with respect to the tire width direction are 18 °.
- the pneumatic tire 210 of the present embodiment is for a construction vehicle, and the thickness of the tread 212 is 60 mm or more in the center.
- a belt 218 having a plurality of belt ply forces is embedded between the belt 6 and the belt 6.
- the durability of the bone (or blade (metal plate)) of the mold for forming 222 is not preferable.
- the pneumatic tire of the present invention can be applied to an application of traveling on rough terrain with a construction vehicle or the like.
