Pneumatic vehicle tyre
The invention relates to a pneumatic vehicle tire comprising a tread with profile positives delimited by grooves, including profile positives which are provided with sipes, which in plan view run at least in certain portions at an angle of 0° to 50° to the axial direction and have a width of 0.4 mm to 1.6 mm and a depth at the deepest point that is at least the profile depth reduced by 4.5 mm and at most 100% of the profile depth, with the sipes in each case being involved in forming at least one wear indicator. The wear indicator is formed by a sipe portion of the sipe which in plan view has the form of a sun symbol or a snowflake symbol.
1 . A pneumatic vehicle tire comprising:
a tread with a profile depth and profile positives delimited by grooves;
a semi-central profile block of the tread;
a first sipe and a second sipe, which in plan view run at an angle of 0° to 50° to the axial direction and has a width of 0.4 mm to 1.6 mm and a depth at the deepest point that is at least the profile depth reduced by 4.5 mm and at most 100% of a profile depth;
a sun shaped symbol of the first sipe and having a profile depth less than a sipe base;
a snowflake shaped symbol of the second sipe having a profile depth less than the profile depth of the sun shaped symbol;
a wear indicator formed by the first sipe and the second sipe, the wear indicator having a first symbol, a second symbol and a non-symbol portion and indicating a first state of wear;
the first symbol has a first profile depth less than a profile depth of the non-symbol portion and indicating a critical state of wear; and
a symbolic wear indicator formed in a profile rib that runs around a circumference of the tire.
2 . A pneumatic vehicle tire comprising:
a tread with a profile depth and profile positives delimited by grooves;
a semi-central profile block;
a first sipe and a second sipe, which in plan view run at an angle of 0° to 50° to the axial direction and has a width of 0.4 mm to 1.6 mm and a depth at the deepest point that is at least the profile depth reduced by 4.5 mm and at most 100% of a profile depth;
a wear indicator formed by the first sipe and the second sipe, the wear indicator having a first symbol, a second symbol and a non-symbol portion;
the first symbol has a first profile depth less than a profile depth of the non-symbol portion; and
the second symbol has a second profile depth less than the first profile depth.
3 . The tire of claim 2 , wherein the first symbol is part of the first sipe and the second symbol is part of the second sipe and a portion of the first symbol overlaps a portion of the second symbol in a circumferential direction.
4 . The tire of claim 2 , wherein the wear indicator is located between first and second oblique drainage grooves and first and second short grooves.
5 . The tire of claim 2 , wherein the first sipe and the second sipe are delimited by a sipe base having 100 percent of the profile depth.
