It hums terribly. Considering that it was on a BMW car, in which German engineers put not the worst sound insulation. I almost started smoking to find a reason to stop periodically on the side of the road and my head could rest a bit from the hum. and brought it to a tire shop, while my wheels were getting rid of old tires, I sat and tried to understand the composition of the rubber. At first, he reminded me of some galoshes, but looking closer, I realized that it still looks more like rubber for a slingshot. very soft sides, but with all this, for 2 seasons I did not get a single hernia, which surprised me very much. In addition to the fact that it is made of rubber from which galoshes or slingshots are usually made, it weighs clearly more than in the same dimension, for example Continental, I also carried out this test in the same tire fitting. After I drove out satisfied on the new tires, I immediately suspected something was wrong, at first it seemed that the handbrake was raised, then it seemed that in addition to the rubber, they also installed a tow bar on the car to which the house was attached on wheels. As a result, having added the formulas in my mind, I realized that apparently its weight makes itself felt. But then there was also a feeling that they had thrown me in a tire shop and put R13 or R14 wheels, because the car became jelly-like. This is when you hit the jelly with your finger and it still fluctuates for a couple of seconds. These are the feelings that haunted me for all 2 seasons. But every time I approached the car, I realized that my wheels were still on it. It also did not pass the rain test. Therefore out of harm's way in the rain, I moved at a speed of 60 km. H, because careless pressing on the gas pedal turned my car into an alcoholic who wears all over the road and who is not able to control his movements, and sometimes even catches delirium tremens.
