Hello friends, I have bought new winter tires that give me a bit of concern. 2 profiles have 7mm, but the other 2 only 3mm. Now my question to the car and tire experts: How risky is it when I mount the 2 bad tyres in the back? You slip if only in the front, but I would have good grip. Maybe someone also has a similar tyre problem and can report a little about his experiences with it. I would like to thank you for reading and even more for this.
