I will most likely be purchasing a 2009 Acadia arriving at my local dealership within the next week or so. It has the factory upgraded 19 inch wheels and tires. I plan on purchasing a set of dealer installed 20 inch wheels and tires. I don't plan on keeping the 19s as a winter set and I don't plan on selling the car for 8-12 years so I can't really keep the 19s to put on when I sell it. What do you think I should do with the wheels and tires? Sell on Craiglist, Ebay, try for a dealer credit and have them keep them, or see if someone on this board would want them? Any opinions are greatly appreciated. Thanks.
