入りタイヤ、特に乗用車用空気入りタイヤに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pneumatic tire capable of reducing outside noise without deteriorating wet performance (drainability), and more particularly to a pneumatic tire for passenger cars.

非常に難しくなっている。2. Description of the Related Art In recent years, vehicle exterior noise regulations have become more and more strict in connection with environmental protection problems. On the other hand, flattering of pneumatic tires for passenger cars is progressing in response to higher performance of vehicles, and the tread of the tires is becoming wider accordingly. However, as is well known, widening the tread deteriorates the noise outside the vehicle, and it is very difficult to comply with the above-mentioned noise regulation.

影響が大となる。By the way, in pneumatic tires for passenger cars,
In order to improve the drainage property, there is one in which a plurality of linear main grooves extending in the tire circumferential direction are provided on the tread surface. In a pneumatic tire having such a tread pattern, air trapped between the main groove and the ground contact surface vibrates to generate air column resonance sound when the tire rotates, and the air column resonance sound causes noise outside the vehicle. It is the main factor. In particular, when a plurality of lug grooves extending in the tire width direction are provided on the tread surface, the air column resonance noise has a great influence on the vehicle exterior noise.

見出されていなかった。The sound pressure of such an air column resonance sound can be lowered by narrowing the groove width of these grooves. However, if the groove width is narrowed, the drainage characteristic which is the original characteristic of the grooves is lowered.
This leads to deterioration of the wet performance of the tire, especially the wet cornering characteristics. Therefore, in a pneumatic tire having a tread pattern in which a linear main groove is arranged in the tire circumferential direction or a lug groove is arranged in the tire width direction as described above, the improvement of the exterior noise characteristics and the wet performance are mutually exclusive. However, no method has been found for achieving both.

It is to provide a pneumatic tire that can reduce the noise outside the vehicle without causing it.

In addition, as a result of examining the drainage, it was found that the grooves in the central region of the tread and in the vicinity thereof greatly contribute to the drainage compared to the grooves in other places. The present invention has been made based on such knowledge, and the groove width of the groove is made as narrow as possible within the range where the drainage performance of the groove in the tread central region and its vicinity is not sacrificed. The vibration amplification effect of is reduced. For this reason, in the present invention, the air column resonance sound is reduced while maintaining the drainage property by setting the groove interval L and the total groove width ΣG as described above.

Further, in the present invention, the ground contact center area refers to an area extending from the tire equator line to the left and right sides in the width direction by 25% of the ground contact width W.
