I bought a car on these tires with a mileage of 45,000 km. and 4 years old (the car was equipped with them from the factory). I immediately noticed that the rest of the tread was "fat", but the appearance left much to be desired (tread peeling, cracks are visible in places) on all four tires. How the car was operated and at what pressure they drove is unknown. (The car was purchased in the south, so the representative can not raise the issue of improper storage (tires "from birth" were on the car). For the sake of interest, I went to aliexpress to read reviews - I saw a familiar picture with a collapsing tread. As a result, I did not wait until tires will fly apart on the trip and bought a set of tires from another manufacturer.
I've added some photos to help enhance the overall impression of my review.
