I consider myself an average Joe in this respect.
I have to concur with Notch.
We have been using Michelin Cross Climate + and Bridgestone Weather Control A005 for years.
Lately we moved to Michelin Cross Climate 2 and Bridgestone Weather Control A005 Evo.
They have both been excellent performers in the cold, with good braking and grip in the wet.
The times we have had snow, they have been much grippier than our previous Summer choices.
Well happy with them.
So what advantage do summer tyres give to summer driving?
Why should anyone in the UK change between seasonal tyres, when the technology is there for a single tyre to perform in all seasons and all weathers?
Summer tyre rubber compounds are geared to working best in warmer temperatures, just as Winter tyres work better at very cold temperatures. The best solution would be to have a spare set of rims with Winters and swap them as the seasons change.
All-season tyres have a mixture of characteristics that perform well in both seasons. They are not as good as swapping rims, but they are a good compromise.
And obviously you only need one set of wheels/ tyres.
And as time goes on, all-season tyres are getting better and better.
