All rubber is expensive here, and UM has a point on economy. I would consider getting another set of summers fitted in the UK, but buy a set of winters to, if you have space to transport them over here. Drive over on the summers, have the winters put on when you get here, and ask the tyre place to store the summers for you. It only cost us 30 chf to get ours stored ready for swapping when the weather changes . The Continentals for my car are 20% more expensive here than the UK
