I tried to get to work this am and a few tasty snow drifts on the back roads, tyres kept me moving no issues at all, even snow a foot deep nearly that had drifted. My other half couldn't even get her A1 off the drive !
I had to turn round 3 times with people stuck and even when turning on small roads I had pretty high confidence I would be fine.
Continental winter contacts on my BMW and highly recommend. They will do at least one more winter, maybe 2.
