Lexus GS300h Tyres

I purchased a set of tires in 2021, all manufactured in the same year and made in Germany. Unfortunately, I can't speak highly of these tires. I reside in Riga, Latvia, where the road conditions are arguably among the worst in Europe. However, at this point, I've been using these tires for the second season, and they have deteriorated significantly. Recently, I had them balanced, and on the testing stand, it became evident just how "out of shape" they were. Consequently, when driving at speed and during braking, the entire vehicle experiences noticeable jerking. To be fair, I initially suspected issues with the brakes and replaced the brakes on the entire car, but the problem persisted. It was only then that I realized the root cause was the tires. I never expected such poor quality, and essentially, the tires became unusable halfway through their second season of use.
