Problems solved by technology

Especially due to the relatively high tread depth required for the tread of off-road tires, which is necessary on unpaved ground to ensure good traction characteristics, there are unavoidable disadvantages on dry paved roads, especially in terms of handling and braking characteristics

Embodiment Construction

[0016] The present invention relates to a specific design of the tread 1 of a pneumatic tire for vehicles, equally suitable for off-road use and on-road use. Such tires are commonly known as all-terrain or off-road tyres, and their tread has a greater tread depth (in the range of 12mm) than conventional tires for passenger motor vehicles. In order for such tires to have good traction properties on unpaved ground, a greater tread depth is especially required.

[0017] In the following description as well as in the patent claims, the angles specified in the context of a groove relate to the center line or direction of extension of said groove. All heights are measured along the radial direction.

[0018] figure 1 The tread 1 shown in has a pronounced block structure with in each case a shoulder row of blocks 2, a central row of blocks 3 extending along the center line of the tire (line A-A), and arranged in Two middle block rows 4 between the central block row 3 and the shoul...

Abstract

The invention relates to a pneumatic vehicle tyre, in particular an all-terrain or off-road tyre, having a tread (1) which is broken down by circumferential grooves (5, 5') having the intended tread depth (T) into block rows (2, 3, 4) running in the circumferential direction and / or into profiled ribs structured like profiled blocks, wherein block rows (2, 3, 4) are divided into blocks (2a, 3a, 4a)by transverse grooves (6, 7, 8) and, like profiled ribs structured like profiled blocks, are provided with blind grooves (9, 10, 11) emanating from the circumferential grooves (5, 5'). Transverse grooves (6, 7, 8) and / or blind grooves (9, 10, 11) are provided which have a smaller depth than the tread depth (T) owing to a link between the adjacent blocks (2a, 3a, 4a) in the circumferential direction and / or the block-like structures, wherein the link has at least two link steps (12, 12', 13, 13') of different heights (h1, h2, h3, h4), of which the lowest is formed at the region where the transverse grooves (6, 7, 8) and / or the blind grooves (9, 10, 11) open into the circumferential grooves (5, 5'), and the highest link step (13, 13') is formed in the middle region of transverse grooves (6,7, 8) and in the inner end region of blind grooves (9, 10, 11).

Description

technical field [0001] The invention relates to a pneumatic tire for vehicles, in particular an all-terrain tire or an off-road tire, having a tread divided by circumferential grooves of a provided tread depth extending in a circumferential manner in the circumferential direction row of blocks and / or ribs configured in a block manner, wherein these rows of blocks are divided into blocks by transverse grooves and equipped with closed grooves starting from these circumferential grooves like the ribs configured in a block manner pattern. Background technique [0002] All-terrain or off-road tires generally have a tread with a pronounced block structure, for example due to the fact that the tread is equipped with rows of blocks and / or a tread band configured in a block manner, wherein, depending on the preferred use , ie whether the tire is primarily intended for off-road use or whether the tire also runs on paved ground, a rib or block structure is common. In the case of know...
