OK, My Dad has a 2005 CPO 745Li and this will be his first winter with it. He traded in his 740iL and was told the OE 16" basket weaves with the Nokian WR snow tires would not fit the 2005. He therefore let them go with the car, along with the set of 18" staggard M parallel's from the sport package. My question is, it has been a few years since he has bought snow tires and I am looking for input as to what works well on these cars. We are in the Midwest so we get everything from deep snow to ice covered roads for a few weeks at a stretch. He is keeping going to mount them on the stock 18" wheels. Thanks in advance....
