    摘要： The present invention relates to a wear indicator for a vehicle tire (1), the tread of said tire being provided with grooves (2) to improve the grip. As taught by the invention, the surface of the tread in contact with the road surface is provided with indicators (5) indicating the momentary groove depth (H) of the tire, said indicators forming at least one group of elements and extending in radial direction into the tire. The element depth grows by predetermined steps from the shortest element to the longest element. The indicator is formed from a sipe(5) the depth of which is advantageously smaller than the depth (H) of said groove and the cross-section of which in the direction of the tread forms a number, letter, sign or symbol, image or equivalent determining the groove depth of the tread on the height of the plane in the direction of the tread which is tangential to the bottom (2p) of the capillary groove.
