I have had the personal experience with using the Schwalbe marathon winter tyres and i couldn't recommend them enough to someone is commuting in the winter months when the weather is not great and their is lots of ice around
One thing you will have to bear in mind when you are using Schwalbe marathon winter tyres is that you will lose studs when you are cycling
it is part and parcel of it all
i would much prefer to replace some studs then to replace some parts on my bike which would cost a lot more then some studs
For example when i have cycled in ice on a 25 miles commute the highest amount of studs i have lost was seven
Studs are easy to get hold of you can get them off the internet

Not really bank account breaking news really £5 for 100 studs
Another thing you can do is buy the Schwalbe tool to help you put the stubs back in the tyre too which makes life more easier for yourself when you putting them in

if you spray some lubricant into the hole where the stub has come out it does help to get the new stub in the tyre and seated properly inside the tyre
it does take some practice but you will soon get the hang of it i am sure.
The only advice i can give you is make sure you run your tyres at about "65PSI" which is recommend from Schwalbe them selfs and check your
studs regular so that it would stop you slipping on the ice
i have rode on a lot of ice during the winter i am confident riding on it
when ever now because i know the studs will grip the road with no
problems it was defiantly worth the investment in buying stud tyres
for the winter
i was very lucky to have to set of wheels a summer set and winter set so i have one for the winter weather and one set for the summer weather to save me swapping tyres over all the time
just thought i would warn you sometimes the Schwalbe winter marathon
can be a bit of nightmare to get on the rim because they are tight but it
does depend on your rims too.
