Just see in my papers that the DEKRA man, along with the chassis and the rims, also registered my tyre size a few weeks ago. 225/45 R17 91Y. On Wikipedia I find under “Speed Index” under Y a 300…. km/h. Isn’t that a little bit of safety reserve for a car with a registered 207 km/h tip? I don’t run now and buy me Veyron tires. Do I get what I’m missing or did the examiner slip? Is (15″ rich V-tires. Is the war against me?
