The Swedea and the Krauts use studded tires. No magic secrets there.

No one is saying anything about "magic secrets" other than you. You are
wrong about Germany studded tyres are banned there. The use of winter
tyres is mandatory in Germany, winter tyres are not (necessarily)
studded, although mine have holes for studs to be mounted if required.

Although studded tyres are sometimes used in Sweden, they are not the
norm and are only used in lattitudes that have permanent snow in winter.
Studded tyres drastically degrade performance on tarmac surfaces.

As usual Harry old boy, you're full of (sh)it.
