I also have a set of Goodyear LS2 run-flat in my garage right now. I am debating whether I should put snow tires on. Mine is 550i RWD and I live in NE Ohio where we do have lake effect snow.
My Audi quattro came with LS2 as stock tires although they had been used for 4 winters but I never liked it. Later on I switched to winter tires and they felt much better.
