Tire Sidewall problems of the 2006 Volkswagen Jetta

I purchased a 2006 vw Jetta in late 2008, early 2009. The car was brand new and sat in the showroom for two years. After of driving for 1 1/2 years, the tire sidewalls began to separate. Continental made the adjustment and I replaced the tires thinking that sitting in a showroom for that much time, they probably dry rotted. Today, I am having to replace all four tires again after 13 months for the same reason, sidewall separation. Reading the complaints on this site and others, it appears there is a serious issue here for sidewalls on continental tires. The size is 225/45r 17. The tires are contipro contact.

I noticed that the side walls of my continental tires on my 2006 vw Jetta were cracked(there were 25k miles on the tires). I reported this to continental -mr. Carl walker. I replaced the tires with bridgestones. I still have the originals. I was told to take the tires to merchant's tire on woodfied road in gaithersburg, MD and have them inspected and the tread depth measured. I did this immediately after speaking to mr. Walker. The sales rep. At merchant's called mr. Walker after inspection while I was present and told him that the sidewalls were indeed dangerously cracked on all 4 tires and that the tread depth was almostlike new. I was promised 60% compensation for the continental tires by continental's rep. Carl walker ( claim # 244382) - phone #7045834819 -in October but have received nothing. These tires are unsafe and it is only luck that prevented a serious accident due to their failure. Vw says they have no jurisdiction over continental even though they supply tires to thousands of vw vehicles. It seem that vw and continental want to ignore the problem for me and I assume all other owners of these tires.

Contipro tires. Three of the tires on my new car have had sidewalls bulges. The first I feel was my fault. I drove on the tire that had low tire pressure. But the two other tires have not had any compromising situations. Each tire had less than 5,000 miles on it. Continental tire warranty is a joke, they have been no assistance. I have never had tires fail me, I have always just worn them out.
