Abstract
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.
Claims5
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.
