Hi, I bought a new car this week, EZ 2017. The winter tires on the car (Fulda crystal control hp2) have just over 4mm profile. But DOT3414==>7.5 years old. My question is, is it worth buying new winter tires now? The winter tires are currently very cheap. For 4 Michelin or Bridgestone winter tires I pay about 100 EUR less compared to October. I plan to go to Austria and Poland next week, where there is a lot of snow. What would you do in my place? Buy new tyres now, or wait until October? Thank you in advance. Greetings from Stuttgart
