On ice you will always be best off with premium studded tyres. The metal studs can dig into the ice and create the grip on ice that you need for braking and acceleration. If they are allowed to be used, which they are in most countries, they are the best winter tyres that you can have. The modern friction tyres, also known as non-studded tyres, are today almost as good at creating grip on ice and they are more flexible as they don’t come with any restrictions. Studded tyres will have date restrictions for when they can be used and they are not allowed in Germany and Poland, which can cause problems if you plan to visit or drive through either of them on a trip.
