Both Sweden and Finland had tyre manufacturing, but for Sweden that production was moved to Portugal a very long time ago after it was sold to a German company. Nowadays you only have production in Finland and they also have a test center referred to as white hell, which is the northernmost test center in the world and home of some of the harshest winter conditions. This allows for some of the best testing conditions that allow you to develop the best tyres for arctic winter conditions. The Finnish manufacturer Nokian Tyres was actually the inventor of winter tyres back in 1935.
