+1 for winter tyres.
I got caught in some snow on boxing day in sheffield with Goodyear Assy2 and I expected the worst. But, they got me home. Passed 5 front wheel drive cars on a hill which were stationary and spinning but when it got steep (the hill to Manor Top from the Gleadless side) I needed a push. On the flat and a slight gradient it did the job although winter tyres would make all the difference and be safer.
