Any dealer in the US can order you a winter set up as well. Call around as the price can vary.
I would imagine Tirerack probably needs a car to measure to see what would fit - happens a lot with a new model.
And stand the best chance of not being damaged when they encounter winter weather driving conditions (potholes). Light wheels are great but that comes at a price.While it is true that they are heavy, here in Calgary the Volvo OEM setup was actually cheaper than doing it at a local tire shop.
I am not talking ultralight wheels but rims that are at least three pound lighter and flow flowed.True, lesser unsprung weight is a good thing to an extent. All I'm saying is that a $200 light weight wheel will most likely be as strong as an OEM one. In some cases you get what you pay for this is one of those cases. Get a spare because in a year or two when you need a replacement they may not be available. Ask me how I know this, lol.
