I bought tires in the fall of 17, the production date was autumn 16, after two years of use, the wheel began to deflate, I drove to a tire fitting, the inspection did not reveal holes or screws in the wheel, lowering the wheel into the bath, they found very small bubbles that came from many places on the tread, without any or visible damage, that is, the rubber stupidly began to exfoliate. For this money and the production of Germany, I do not advise anyone, before that I used Japanese, washed to zero and no problems. In general, money wasted.
