I Have been putting winter tyres on my IS250 Auto from new, Got a spare set of identical alloys from ebay and fitted them with mitchelin winter tyres the same sizes as the standard tyres.
I usually put them on in December and take them off in April. This will be the fifth winter for the tyres and they will need replacing next winter.
Got caught out this year with the early snow and could not even get turned in the street with the normal tyres on.
As it was the weekend decided to try a little experiment so I fitted the 2 back wheels, Drove into the road where there was hard packed snow, Applied the foot brake enough to lock the front wheels and tried to pull away.
Bit of wheelspin but the winters pushed me along the road with the front wheels locked.
