Abstract

A system for demonstrating inadequate vehicle tyre tread depth, comprises using coloured rubber which becomes visible once the tread depth is illegal. Use - The method is used to indicate when tyre tread depth is no longer legal. Advantage - The method offers a reliable way of determining inadequate tyre tread depth.

Description

Die Erfindung dient der Sicherheit im Straßenverkehr, zur Beweisführung bei Unfällen und zur nachweisbaren Eigenverantwortung.The invention is used for road safety, to provide evidence Accidents and demonstrable personal responsibility.

Da eine gesetzliche Mindestprofiltiefe von 1,6 mm über die gesamte Reifenauflagefläche gefordert wird, ist der Nachweis mittels Gummieeinfärbung bei Profiltiefeunterschreitung absolut sicher und zuverlässig.As a legal minimum profile depth of 1.6 mm over the entire Tire contact area is required, the proof by means of rubber coloring Absolutely safe and reliable when the profile depth is undershot.

Bei der Reifenherstellung (Profilausformung) wird z.Z. nur mit schwarzer Gummimasse gearbeitet.At the time of tire production (tread formation) only with black Rubber compound worked.

Der wesentliche Unterschied bei dieser Erfindung ist, daß beim Profilaufbau zunächst eine 1,6 mm dicke, beispielsweise rot eingefärbte Gummimasse, aufgetragen wird. Über diese Rotgummischicht wird die schwarze Gummimasse aufgetragen, so daß die übliche Endprofiltiefe erreicht wird.The main difference with this invention is that in profile construction first a 1.6 mm thick, for example red colored rubber mass, is applied. The black rubber mass is over this red rubber layer applied so that the usual final profile depth is reached.

Bei sichtbaren roten Flecken oder roten Streifen, entstanden durch Vollbremsung oder entsprechender Laufleistung, ist der eindeutige Hinweis gegeben, daß die minimal zulässige Profiltiefe unterschritten ist.If there are visible red spots or red stripes, caused by Full braking or corresponding mileage is the clear indication given that the minimum permissible profile depth is undershot.

Claims (5)

1. Die gesetzlich noch zugelassene Reifenprofiltiefe bei PKW- und LKW-Reifen kann z.Z. nur mittels mechanischer Messeinrichtung ermittelt werden.1. The legally permitted tire tread depth for car and truck tires can currently can only be determined using a mechanical measuring device. 2. Das z.Z. übliche Meßverfahren ist nicht fehlerfrei und eindeutig.2. The currently The usual measuring method is not error-free and clear. 3. Unzulässige Reifenprofiltiefe sind ein sehr hohes Risiko im Straßenverkehr. (Aquaplaning)3. Impermissible tire tread depth is a very high risk in road traffic. (Aquaplaning) 4. Die Gummieinfärbung, bei Beginn der unzulässigen Profiltiefe, ist ein absolut sicheres und leicht erkennbares Zustandsmerkmal.4. The rubber coloring, at the beginning of the impermissible profile depth, is an absolute safe and easily recognizable condition. 5. PKW- und LKW-Reifen mit Gummieinfärbung ab unzulässiger Profiltiefe sind bislang nicht auf dem Markt.5. Car and truck tires with rubber coloring from an inadmissible tread depth are not yet on the market.
