Abstract
A pneumatic vehicle tire having a tread is provided. Spikes are arranged in spike tracks provided in respective spike zones, where both the spike tracks and the spike zones run in an encircling manner over the circumference of the tread. Each spike has a spike pin with an end portion projecting beyond the tread surface and which is non-circular and elongate and, in a greatest extent, defines a longitudinal axis. A base spike zone has a spike having a longitudinal axis having an angle of about 00 relative to the axial direction and divides the tread into right and left tread halves. In one tread half, the spikes are arranged such that the longitudinal axes assume greater angles relative to the axial direction the further axially outward the spike zone is positioned, the greater angles being between about 50 to about 90 .

2 The improved traction is achieved in that the end portion of the spike pin penetrates the winter road layer during the rolling of the tire and leads to a mechanical connection between tire and road.
It is known from US 6374886 to equip a pneumatic vehicle tire with lamella pins. The tire traction properties in the longitudinal and transverse directions can be influenced with the aid of direction and design of the lamella pins.
EP 1199193 Al discloses a spike which, in top view, has a non-circular, elongate spike root and a non-circular, elongate spike upper part, wherein the spike root and the spike upper part are interlocked in relation to each other and therefore the longitudinal axis of the spike root encloses an angle differing from zero with the longitudinal axis of the spike upper part.
Furthermore, it is known that different types of spike differing by the angle of interlocking are arranged in the tread. For optimum absorption of force, the spikes are arranged in the tread in such a manner that the longitudinal axes are turned from the axial direction at the same angles to the right in the left tire shoulder and to the left in the right tire shoulder. In the central tread region, the longitudinal axes of the spike upper part are oriented approximately axially.
In addition, it is known that the shoulder region of the tread particularly during cornering absorbs lateral or transversely directed forces and contributes significantly to the lateral guidance of the tire. Furthermore, it is known that elongate end portions of spikes arranged parallel to the axial direction of the tire are advantageous for traction.
The invention is based on the object of designing a pneumatic vehicle tire of the type mentioned at the beginning in such a manner that the performance of said tire on a wintry road is improved and the conflict of objectives between transmission of traction force and lateral guidance force is resolved to a greater degree.
The stated object is achieved according to the invention in that at least 2 further spike zones having spikes are arranged in addition to the base spike zone in a tread half, of which spikes the longitudinal axes of the end portions of the spike pins assume greater angles to the axial direction the further axially outward the spike zone of the spike is positioned, and in that Date Recue/Date Received 2020-06-05

3 the longitudinal axes of the end portions of the spike pins of the spikes positioned in said further spike zones assume angles (3, y, 6 in a range from +/- 5 to +/- 90 with respect to the axial direction.
It is essential to the invention that a "fanning out" of the angular size of the spike pins of the spikes arranged in the further spike zones is obtained from a base spike zone arranged in the central tread area in the direction of the tread shoulder. This means that the longitudinal axes of the end portions of the spike pins assume greater angles with respect to the axial direction, the further the spike is positioned in a further spike zone arranged further axially outward. At least one base spike zone is arranged in the center of the tread with a spike pin end portion arranged approximately transversely to the circumferential direction, through which traction forces can be optimally transmitted. The further axially outward a spike is arranged in one of the at least two further spike zones, the greater the angle of the longitudinal axis of the spike pin with respect to the axial direction and is at maximum +/-900. At an angle of +/- 900 in relation to the axial direction, lateral guidance forces can be optimally transmitted in the shoulder region. Since there is now no abrupt transition of the angles of the longitudinal axes of the spike pins across the tread width, but rather, according to the invention, there is a "harmonious" transition in a plurality of steps because of at least two further spike zones with spike pins each having greater angles, the transmission of force from lateral guidance and traction is more even over the tread width.
This has a positive effect on the winter performance of the pneumatic vehicle tire and the conflict of objectives between transmission of traction force and lateral guidance force is resolved to a greater degree.
"Shoulder region" means the profiled tread region that extends axially outward from the outermost circumferential groove, which does not have to run exclusively in the circumferential direction but can also have a zigzag shape.
The "base spike zone" with one or more base spike tracks is always arranged in the central tread region and can lie in the geometric center or outside said geometric center of the tread.

4 When it is described that "a spike is arranged further axially outward", it is meant that this spike is positioned on a spike track which is arranged in a spike zone which is further axially outward.
A positive angle (+) means the rotation of the longitudinal axis clockwise from the axial direction.
A negative angle (-) means the rotation of the longitudinal axis counterclockwise from the axial direction.
A "spike zone" has at least one spike track, but the spike zone can also contain a plurality of spike tracks. In the same spike zone, all of the longitudinal axes of the end portions of the spike pins of the spikes have the same spike angle, which can be in the same direction or alternating in opposite directions.
It is advantageous if all of the spikes in the tread have the same geometry.
All of the spikes in the tread are therefore of the same type of spike. The tire tread can be equipped with spikes using a simple machine which does not have to be able to distinguish between two or more types of spike. Therefore, the production is simple and inexpensive.
The same "type of spike" means that spike pins and spike bodies of the same geometry are assembled in such a way that all of the spikes have the same geometry within the general production spread.
In a spike zone, all of the longitudinal axes of the end portions of the spike pins assume angles of equal size to the axial direction. Said angles can have the same sign (in the same direction), but also positive and negative signs. Angles in the same direction per spike track .. are particularly expedient for directional tires. Alternating opposing angles per spike track are particularly useful for symmetrical non-directional and asymmetrical non-directional tires that do not have a predetermined running direction, because the lateral guidance and traction components can thus be divided symmetrically.
In order to improve the winter properties, it is expedient to use a large number of spike tracks so that the spikes are not placed too close to one another in the same spike track and would possibly ineffectively engage in the scratch track of the previous spike.

5 In one specific embodiment of the invention, the in each case at least two further spike tracks are arranged in each of the two tread halves, wherein, in particular in the case of symmetrical directional tread profiles, all of the angles of the longitudinal axes of the end portions of the spike pins are positive with respect to the axial direction in the one tread half and all angles are negative in the other tread half. The longitudinal axes of the end portions of the spikes are always oriented in the same direction in a spike track, that is to say all are either positive or all negative. In addition, the longitudinal axes of the end portions are all positive in the one tread half and all negative in the other tread half. In this way, a balanced winter performance over the tread width is obtained, in particular in the case of symmetrical directional tread profiles. A uniform and symmetrical distribution of the spike angles and thus a harmonious driving behavior can be generated.
In another embodiment of the invention, the in each case at least two further spike zones are arranged in each of the two tread halves, wherein, in particular in the case of asymmetrical tread profiles, the angles of the longitudinal axes of the end portions of the spike pins with respect to the axial direction in a spike track are of the same size, but have positive and negative signs in an alternating manner over the circumference of said spike track. By this means, a uniform transmission of force is ensured even in the case of asymmetrical tread profiles.
It is expedient if a tread half has 3 to 15 further spike tracks which lie in spike zones. This number of additional spike tracks enables a particularly harmonious "fanning out" of the angles of the end portions in a plurality of stages over the width of the tread. This is expedient because a particularly harmonious driving behavior can thus be produced.

6 the end portions of the spike pins are approximately identical in the two base spike tracks.
"Approximately" means here within the scope of production tolerance. These spikes in the basic track(s) contribute particularly to excellent braking and traction properties, since they are maximally designed for longitudinal transmission of force.
A refinement of the invention is advantageous, in which the base spike zone has one or two base spike tracks which are arranged in the central region of the tread, and in which the longitudinal axes of the end portions of the spike pins of the spikes of the further spike zones assume angles in a range of +/- 50 - +/- 12 with respect to the axial direction in the central tread region and in a range of +/- 12 - +/-900 with respect to the axial direction in the shoulder region. This resolves the conflict of objectives between traction and lateral guidance to a particularly great extent. Due to the dynamic shifting of load during cornering, a longer "ground contact area" arises at the outer shoulder, as a result of which the greatly inclined spikes that are important for the lateral guidance come into their own in particular. When driving straight ahead with a symmetrical "ground contact area", particularly the only slightly inclined central spikes come completely into their own.
In an advantageous refinement of the invention, 7 spike zones are arranged in the tread, of which spike zones three further spike zones are arranged in the left tread half, three further spike zones are arranged in the right tread half and one base spike zone having two spike tracks is arranged in the central region of the tread, and in that the longitudinal axes of the end portions of the spike pins of the spikes assume angles of the following ranges with the axial direction, as viewed from the left to the right over the tread: 30 to 90 , 12 to 30 , 5 to 12 , 0 to +1-7 , 0 to +1-7 , -5 to -12, -12 to -30 , -30 to -90 or vice versa, namely: -30 to -90 , -12 to -30 , -5 to -12 , 0 to +/- 7 , 0 to +/- 7 , 5 to 12 , 12 to 30 , 30 to 90 , wherein the angles become greater the further axially outward the spike is arranged because this is the only way to ensure that the greatly inclined spikes that are important for the lateral guidance are located in the shoulder blocks.

The spike tracks 51, 52, 53, 5B, 5-1, 5_2, 5_3 are assigned to spike zones 101, 102, 103, 10B, 10_1, 10_2, 10_3, the zone boundaries of which are shown in dashed lines. The spike zones 101, 102, 103, 10B, 10_1, 10_2, 10_3 have a certain axial width and are arranged in an encircling manner over the circumference of the tread. In this exemplary embodiment, a spike zone 101, 102, 103, 10B, 10_1, 10_2, 10_3 in each case contains only a single spike track Si, 52, 53, 5B, 5-1, 5-2, 5_3. All of the spikes 4 are of the same type of spike and therefore have the same geometry. A spike 4 has a spike pin with an end portion 6 projecting beyond the tread surface, wherein said end portion 6 in a top view of the tread is non-circular and elongate and, in a greatest extent, defines a longitudinal axis 7. A base spike zone 10B
