had pirelli scorpion road tyre's front contie's rear on a set of 20" in the snow and ice; it was ok but I had my doubts, bit like a space hopper great until you come off, the car slide about a bit on tight corners at about 15mph

changed them for my spare set of 19" scorpions road tyre's once again slid round corners with a camber run off, having to drive the car in then out trying to miss parked cars,

changed the road tyre's for pirelli scorpion snow and ice true 4x4 brilliance, so much better, but the downside was the price but all i could get at the time 'someone did me a favor' I always fall for that one!!. a womans rule of thumb:if it has tyres or testicles your going to have trouble with it

Had a set of AT2 from AJS on mine for a couple of months. Stunning in the mud but even better on snow.

Not slid once. Only when trying to see limits of grip

Went up St Steven hill and left a trail of abandoned cars in my wake. It was if on tarmac not 120mm of snow



This a better shot of the tread 19" btw. My 20" are in the garage and will probably never go back on
