Problems solved by technology

[0009] However, with the above configuration (arrangement), the balance between winter (or white) road performance and regular (or black) road performance is not optimized
Therefore, it is difficult to obtain satisfactory regular (or black) road performance and satisfactory winter (or white) road performance at the same time

Embodiment Construction

[0059] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0060] will refer to figure 1 , figure 2 and image 3 A tread 1 of a tire according to a first embodiment of the present invention is described.

[0061] figure 1 is a schematic perspective view of a part of the tread of the tire according to the first embodiment of the present invention. figure 2 is a schematic plan view of a part of the tread of the tire according to the first embodiment of the present invention. image 3 is along figure 2 A schematic cross-sectional view taken along line III-III in .

[0062] The tread 1 is that of a tire having the size 225 / 45R17 and comprises a contact surface 2 intended for contact with the ground during rolling and having a depth D ( image 3 shown in ) and leads to a plurality of grooves 3 on the contact surface 2 . The plurality of grooves 3 include substantially along the circumferential direction (e...

Abstract

Present invention provides a tread for a tire having a contact face being provided with a plurality of grooves opening to the contact face and a plurality of contact elements being delimited by the plurality of grooves, each the plurality of contact elements having a top face constituting a part of the contact face and at least two incisions opening to the top face and extending radially inward ofthe contact elements, the at least two incisions consisting of at least one thin incision being delimited via two opposed thin incision faces having a width t1 and at least one thick incision being delimited via two opposed thick incision faces having a width t2, the width t2 being thicker than the width t1, the at least one thick incision comprises at least one protrusion protruding from one ofthe thick incision face toward another thick incision face, and the width t2 of the at least one thick incision is at least equal to 1.0 mm.

Description

technical field [0001] The present invention relates to a tire tread, and more particularly to a tire tread provided with various types of incisions for simultaneously improving winter performance and hydroplaning performance. Background technique [0002] In recent years, tires known as "studless" tires suitable for driving on icy and / or snow-covered winter (or white) roads or capable of driving on winter (or white) roads (such as snow-covered roads) Tires known as "winter" or "all-season" tires that drive and maintain high-speed capability on regular (or black) roads are expected to improve performance on regular (or black) roads that are not covered with ice or snow, while Still improves performance on winter (or white) roads. In particular, improvements in hydroplaning performance and / or snow felling (cutting) performance are desired. [0003] In order to improve hydroplaning performance and / or snow felling performance, it is known to be effective to increase voids in ...
