Thee's a little incorrect information floating around here right now. On any New or Used car, the dealership has nothing in the tires. That's why there are Continental and Michelin paperwork inside every owners manual in our cars. Even on a brand new car, the tires have their own warranty. It's not covered through Chrysler. If it was purchased through a 5-Star Chrysler deale as a Certified car, Yes, you have a gripe. There are minimum tread readings that the tires must pass before it can be Certified through Chrysler. I would got to the Tire Store that has the brand of tires that are on your car if you are trying to get someone to pay for them. And Belt seperation would be something that would be covered from the tire manufacturer, as long as something wasn't hit.
