A couple of years ago I needed to replace the front two tyres. Rear tyres were Avons - a hard compound tyre that would have outlasted the car and had already done four years. So I chose to replace them all with all weather tyres. I did my homework, read lots of reviews and picked out the tyres I wanted - Nokian Weatherproof . The reviews rated them highly, even beat many winter tyres in testing.
I have to say that they have been a great buy (248 quid for the set of 4, delivered and fitted - less than other premium summer tyres), grip very well in wet or dry, not much road noise, barely any difference in fuel economy and they've lasted 28months and 30,000 miles so far and still have about 5mm of tread left.
While we don't get much snow in Ormskirk, I do travel in hilly regions regularly and the entrance to our street is on a hill. The difference these tyres have made in the wet, snow or ice is remarkable. I would never go back to just summer tyres.
