2004 Nissan Maxima tires problems

While driving on the nj turn pike at 70 MPH, my husband felt what seemed like a tire going flat. He proceeded to try to get to the shoulder. Suddenly, the left rear tire blew and he totally lost control of the vehicle. He was hit head-on and in the rear. Both he and the driver of the other vehicle were injured and transported to the hospital. Two days later we went to see the car at the towing garage and we saw the rear passenger tire was split on the sidewall.

I purchased a 2004 nissan maxima se with goodyear eagle rsa 245/45/18 size, in sept. 2003. In april 2005 I had all 4 tires replaced because of the sidewall cracking. My car only had 22,000 miles on it. In oct 2006 I had a blowout on the expressway and goodyear couldn't determine if it was from the cracking and I bought a new tire. In june 2007, with only 46000 miles I suffered 3 flat tires due to the cracking (the new tire I just bought was fine).
