Hello, since I drive only about 5,000km per year (mainly rural road) I drove all year round with winter tyres from 2013. The car is a Honda Prelude BJ97 Now the tyres are much more driven at the front than at the back. At the front are still about 3-4mm profile on it and at the back 6mm. Could I then replace the tyres at the front with all year round tyres and continue with the winter tyres at the rear or would it be bad or completely forbidden? I think that I drive the car still about 3 years The Tüvprüfer was already enthusiastic about this.
