Luftreifen für KraftfahrzeugePneumatic tires for automobiles

Die Erfindung "betrifft einen Luftreifen für Kraftfahrzeuge und ist dadurch ge-kennzeichnet, daß er unterhalb seiner Lauffläche an der Grenze der behördlich zugelassenen Profilmindesttiefe oberhalb seines Profilgrundes anders, insbesondere rot gefärbt ist.The invention "relates to a pneumatic tire for motor vehicles and is characterized by the fact that it is below his Tread at the limit of the officially approved minimum profile depth Above its profile base is different, in particular colored red.

Ein solcher Reifen läßt mit dem Abfahren seines Profils für jedermann deutlich werden, daß eine Reifenerneuerung fällig ist. Dem Kraftfahrzeughalter gibt das erhöhte Fahrsicherheit, den Überwachungsorganen erspart es umständliche Kontrollen,, Selbst während der Fahrt läßt sich ein diesbezüglicher Mangel an der Erscheinung des Farbbildes feststellen. Kein Besitzer eines mit einem solchen Reifen ausgerüsteten Kraftfahrzeugs kann sich trauen, damit eine Fahrt anzutreten. Der allgemeinen Verkehrssicherheit kommt das zugute.Such a tire makes it clear to everyone that a tire is to be renewed when its tread pattern is traced is due. This gives the motor vehicle owner increased driving safety and saves the monitoring organs cumbersome Controls ,, Even while driving, a related Notice the lack of color image appearance. No owner of one equipped with such a tire Motor vehicle can dare to start a journey with it. This is important for general road safety benefit.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch in einem Querschnitt dargestellt.An embodiment of the invention is shown schematically in the drawing in a cross section.

Der Luftreifen 1 trägt an seiner Lauffläche 2 eine
Profilierung 3. Liegt die Grenze der behördlich aus Sicherheitsgründen zugelassenen Profilmindesttiefe bei 4, z.B. zwei Millimeter oberhalb des Profilgrundes 5, so ist von dieser Grenze 4 ab bei 6 in einer Schichtstärke, die zweckmäßig bis zum Profilgrund 5 reicht, das Reifenmaterial
anders, vorzugsweise auffällig, z.B. rot gefärbt.The pneumatic tire 1 has a tread 2 on its tread
Profiling 3. If the limit of the officially approved minimum tread depth for safety reasons is 4, e.g. two millimeters above the tread base 5, from this limit 4 onwards at 6 in a layer thickness that expediently extends to tread base 5, the tire material
different, preferably conspicuous, e.g. colored red.
