I live in Indiana and the same thing has happened to my wheels. Bottom line is if you live where there is salt on the road, don't buy chrome wheels. Regardless of what anyone says, they will pit. Typically chrome wheels first start pitting where the tire bead is (which is probably why you are losing air). I've been there too and the only thing I can recommend is to use alloy wheels, unless you plan on not driving the car in the winter or running through the car wash after every snow. But even then that doesn't always work. If you really like chrome there is a company in Detriot that has a new method of chroming wheels. They have a 5 yr/100,000 mile warranty against pitting and peeling. The website is www.uswheelexchange.com. Check it out, it may be the way to go.
