A NOISE IMPROVING TREAD

The tread has a contact face that is provided with at least one circumferential groove and a transverse grooves opening to the contact face and delimiting contact elements. The tread has a center region and shoulder regions and is provided with at least one compressive contact element among the contact elements. A volumetric void ratio of the compressive contact element in a unit region surrounded by a center of the at least one circumferential groove and a center of the transverse grooves delimiting the compressive contact element is at least equal to 25%. An aspect ratio, which is defined as a ratio of a surface of the compressive contact element supposed to contact with ground divided by a sum of a surface area of the compressive contact element touching with air other than the surface of the compressive contact element supposed to contact with ground, is at most 70%.
