For starters, you will not have a problem mixing those 2 winter sports with 2 more if they only have 4000 miles on them. As for wheels, the most popular thing we have been using this winter for E39 528's in 17 inch has been the ATP Type 5's. they are a M3 (m Kontour) replica that use a BMW center cap. There are also many other wheel options depending on you tastes. If you get a moment, give me a call and we can get you set up. thanks Aaron 800.428.8355 x395
