I had a similar problem last winter on my Chrysler. Hit a pothole on the interstate at about 75mph. That wheel looked D shaped when I got out of the car to look at it. Miraculously, it still held air. That wheel was ONLY $400, but I knew when I bought the new MKX with the 20's that this could possibly be trouble. As we were signing the paper for the car, the finance manager asked about wheel coverage? Any damage, any problems with the wheels, they are covered, no questions asked. Like road hazard for your wheels and even covers the tires. $499.00 for as long as you own the car. Sounds a little pricey, but I took it. I had a heck of a time finding the $400 Chrysler wheel, I didn't even want to try to find a replacement 20" Lincoln wheel. If I ever have problems, just take it to the dealer and they handle everything. Both of my Lincolns have this coverage. When you live in Illinois, the roads are SO bad that this is just a little extra piece of mind.
