Order them online and have a local shop install them, perhaps?

Try www.PointS.fr

At for example:

have to second richard here. nobody can beat their prices. they have a swiss website too (you can access it from the french one) i've ordered tires from them on three occasions and i've always been satisfied. they can deliver to your door or to your mechanic. the only downside is that you'll have to find a place to store your summer tires if you're mechanic doesn't have any space. whereas if you go to a big garage they will store your old tires, sell you new tires, and mount them onto your car - easier BUT usually much more expensive (20-50% depending on garage and type of tire)

hey who can change from summer tyres to winter tyres is there some shops that do this?

Hi, 

Last year spent quite a lot of time getting best option (including hopping over to france) came out cheapest way to do it is to order them on line and get them delivered to a garage. They ll change your tires for approx 120Chf extra in general.
