Driving to work today in the Peak District and the outside temperature was -18. Had a few twitchy moments with the icy roads and thought about whether it would be worth buying a set of winter tyres. The cheapest price I can find is over £150 a tyre from mytyres. Can anyone on hear recommend somewhere to consider getting them? Make, price etc? Mine are 225/40/18's.

I live near a Kwik Fit and HiQ but cant find anything useful on their websites. Ta.
