TREAD PROFILE OF A SNOW TIRE

摘要

Tread profile of a snow tire for a vehicle in which at least two vehicle wheels are rotatably mountable outside of a longitudinal vehicle axis. The tread profil e includes a plurality of profile block rows aligned in a circumferential directio n and distributed in an axial direction from a first tire shoulder adapted to be posit ioned toward an outside of the vehicle in an operational state of the tire on the vehi cle to a second tire shoulder adapted to be positioned toward an inside of the vehicle in an operational state of the tire on the vehicle. The tread profile also includes a plurality of channels aligned in a circumferential direction and being arranged to axially separate the plurality of profile block rows from each other, and the plurality of channels includes a first circumferential channel positioned to divide the tread profile into two axial regions of functionally different structure, and each axial regio n axially extending from one the first and second tire shoulders to the first circumferent ial channel. The plurality of profile block rows includes a plurality of profile blo ck elements, and the plurality of profile block elements in the axial region extend ing from the circumferential channel to the first tire shoulder have a higher latera l thrust stiffness than the plurality of profile block elements in the axial region exten ding from the first circumferential channel to the second tire shoulder.
