I have a referral award for the 21" arachnids, so when they come in to the Charlotte Service Center I'm wanting to sell my current wheels/tires so that I don't have to truck them back down to Charleston. I currently have the 19" grey wheels and the original tires have ~6K miles on them. I do have one small spot of 'curb rash' on one of the wheels, but otherwise they're great. Anyone had any experience trying to coordinate a sale at a SC like this? Any thoughts/suggestions? Thanks.
