Performance summer tires lose traction when the weather gets cold. You can get a set of wheels with winter or snow tires. This is what I did with my E90 and E92. Got the winter setup from tire rack. Took me about 45mins to swap them out each season change. Fall -> winter. Winter -> spring. BMW now offers all seasons instead of just performance summers when checking the ZHP.Is it that bad to drive around during winter with default tires on the MYP?
