I’ve been on winter tyres for the last five winters. My 1.5DCI Renault Modus is happily clocking 65mpg on my 90mile daily commute across the southern Yorkshire Dales on Kleber Krisalp tyres. I leave them on year round because in this area and climate they are much the safer bet when coping with high rainfall, variable temperatures, cow pats and mud on the road. The only downside is having to replace a damaged tyre in the summer months when the Krisalps aren't available. Luckily Mytyres.co.uk have come up trumps once again this year with delivery direct to my front door.
