May be possibly out of budget depending on size, but I used Conti WinterContact TS830P last year on her diesel Golf.
They were superb in the cold weather, not just when the snow fell.
Half way through winter I tried to get some for the Gti but couldn't get stock. So just floundered around as the Pilot Sport3 were very poor when compared to proper 'winter tyres'.
The Conti tyres were awesome in snow/ice, but also very good on cold wet tarmac too and hardly wore at all.
Her Golf has now morphed into a A4 Avant, so the 225/40/18's are going on mine and we ordered another set of TS830P last Friday for the Audi in the 245/40/18 flavour, 97V load/speed rating.
My tyre dealer tells me Continental are not putting these into production till 1st Oct, so guess that's when winter production starts for that company, as i'd asked for 2011 'stock'.
Never used Goodyear winters but would imagine they're equally as good as others mentioned.
Either way I'm converted and always plan to use them each year. I live in the North East of England.
As they say up here "it's a bit nippy like.."
