Tires TIGAR or GOODRIDGE

I got a set of winter tires from them, at first they were perfect but 3 of them lost the shape (they were not perfectly round) just after 1 year and 30k KM and car started shaking progressively. They were on the car all the time and actively driven on. So it wasn't user error, the car did not sit in the same place more than 4-5 days in a row. It was just poor build quality.

The Goodrides on the cheap M3 I bought gripped like greased plastic in the snow.
