They were installed tonight on 4/5/2022. For now, I have to say that they are very quiet. I installed them at a price of 375 euros including installation. I will come back for any updates.

I installed these specific tires at the end of July. Until today, 11/11/2021, I have covered approximately 6,000 km. It is the most amazing tire I have ever worn on my car, an OPEL ASTRA 1600cc TURBO with 180 horsepower. I drove most of the kilometers on a long European trip. Truly, the ASTRA's driving behavior has changed. It has become a completely different car, safer, more secure, and more stable in its handling. So far, I have not noticed anything negative. As for its durability, we will see over time, once I cover more kilometers. I forgot to mention that they heat up very quickly, so they perform instantly and effectively over short distances.
