tire usage time - 1 season, i. e. 3 months, all the flaws appeared on the whole set, although they were bought in different stores and in different batches, the rumble appears so that the sensations speak of a rocket launch, or they removed all the mufflers on the car. I used it on a Matiz, according to my passport, the pressure was 2 atm. , It rows forward well, but with the slightest wind, or when cornering, or in a rut, there is no grip on the road, be it ice or snow. before that there was an experience of using "Pirelli", which drove 6 seasons - heaven and earth!
