general problems of the 2006 Chrysler 300

Purchased 4 new tires . Have had 3 incidences of stem failure resulting in flat tires. Tire stems were replaced at tire kingdom, place of purchase.

Had tires inspected because of noises , was told that at least 3 tires are defective, or choppy, also bumpy and vibration, tires were checked at the new car dealership and at the local good year tire center.

I have a 2006 Chrysler 300 hemi. Every since I bought it, I've been having problems with my tires and recently noticed that they are wearing down unevenly and quickly. I only have 46,000 miles on the car. Soon after noticing it, I saw on the news that they were doing a recall on continental tires. Later on that same day, I talked with a friend who had the exact same car I have. He informed me that he had seen the recall on the news as well. He told me that he had called the number that was given for the company and that they had paid him for each of his tires and also replaced them. I've been trying to get in contact with the company, but I haven't been able to get a hold of anyone by phone nor email. I really need to find out more about the recall and how I can go about getting my tires replaced as soon as possible.

Acquired 2006 300c - 2/1/2006 - w/continental tires. Noticed cupping on left front tire at 3,00 miles. Dealer checked alignment, suspension, etc. And said: "everything is within specs" and rotated tires. Service advisor stated tires should be rotated every 3,000 miles (?????). Follow-up call w/service manager - stated that the continental tires are "very soft" and wear prematurely. Asked about the "cradle mod" - and he stated that the "cradle mod" and revised alignment specs would have been applied to this vehicle, since it is a 2006. Left front tire is now cupping again at 6,000 miles. Why are these tires performing so badly when goodyear tires (also shipped on this vehicle) are performing ok? why would Chrysler continue to ship these vehicles w/the continental tires?.
