Bite the bullet, and get a dedicated set of snow tires. For a
performance automobile, such as an E55, there is no better solution.
Since I did for my C36, the only thing that concerns me is if the snow
is deep enough to be plowed by the front bumper.
Do NOT put the A/S tires on your car. It will handle completely
differently. ALL BAD. Made that mistake trying to get more life out of the
tires and some winter usage. Pulled them off after 50 miles. Costly
mistake. Do like the other say and get dedicated tires and wheels if you
need to drive in the snow.
I have two E320's, both with extra alloys and snow tires. One car has
Bridgestone Blizzaks and the other has Micheline X-Ice snow tires.
The Blizzaks are the gold standard for heavy snow and ice. They have
amazing traction however they are noisy and wear quickly. If you don't
plan on driving in extremely deep snow I'd suggest the X-Ice tires which
do an admirable job.
