Because of the UK's weather, I would have preferred all season tyres for the winter but couldn't find any in my size. I needed to be able to cope with winter weather should it do its worst so I bought the Wintracs to see me through to the summer. They were much better than expected in all respects, coped well with the 320bhp of a Tiguan R and never gave me any concerns. I traded in the Tiguan before I needed to swap back to summer tyres.
