Honestly – who really measures his profile after? There are the funny wear markers, on the flank marked with TWI. Also mine occasionally looks after the indicators – still air? Yes, well then everything is good. But now I have dealt with the new Metzeler Sportec M7RR a little closer, because I wanted to write a tire test for it. At first glance I noticed that the residual profile depth at reach of the TWI lakeehhhhhr is low. http://www.motor-talk.de/…/vom-hasser-zum-fan-t5061967.html The request in the Sportec forum has been answered in real terms. Hello, we are happy to take up the topic of “TWI indicators” in order to do an enlightening job. The TWI indicators can be found on all motorcycle tyres which are also intended for the export market (USA, North America). This affects every motorcycle tyre manufacturer who exports tyres to the regions mentioned above. The law in North America sc These indicators are completely irrelevant for German legislation. In Germany, as in Austria, the legislator prescribes a minimum profile depth of 1.6 mm. The vehicle owner is responsible for the compliance with the minimum profile depth himself At least one should say goodbye to the erroneous assumption that one can also drive the tyre until the TWI is reached – bad trap! Already at the Z6 Met tricked with the wear and tear – in the middle of the running surfaces no profile was “carved”. Suddenly some riders grinned the carcass in the middle of the tour.
