I saw the brief chat yesterday about winter tyres and MPG. It reminded me of this site that I came across when I was a Volvo man. http://www.tyrereviews.co.uk
Worth a look to see other peoples opinions and findings.
I did notice a slight reduction in fuel economy on my V50 with GoodYear UltraGrip 8's fitted
They also fell "squishy" when compared to the summer tyres that came off.
However any comparison on the Berlingo is not really possible till I switch to a matched set of summer tyres.
As the tyres that came off were a mix and match of Chinese brands and one know brand, can't remember which brand to be honest, it was a decent one though.
