Not having the right tyres on, eh ???
My selection for the winter....
Mazda 2 - Hankok Winter (something)
VW Golf I Cab - GoodYear UltraGrip Performance
Audi S4 Avant - Conti TS 830P
Audi Quattro - Nokian Hakkapeliitta 7 (sitting and waiting to go on)
Jonsered garden tractor - snowchains & dozerblade
Not quite so extreme as this guy Arne from Sweden...
