Winter Tyres.

[Kev880]

Picked my daughter up the other evening, it was very foggy and frosty the roads were white with frost and they were very very slippery.
I have just looked on various websites at winter tyres and they are not cheap for the amount they would get used.
My queston is as my car is front wheel drive could you just put winter tyres on the front?
My thinking is that it is a no no but im no tyre expert!
