general problems of the 2007 Infiniti M35

All four tires are disintegrating after 28k miles. They are warrantied for 45k. I do not drive on gravel nor do I drive in an unsafe manner.

2007 Infiniti M35 (preowned certified) at 30,000 miles, with stock tires, driving approximately 70 mph on the highway, I started experiencing rumbling in the car. When I started to slow down, it became overwhelming. I pulled over to the side of the road, and my tire had been ripped to shreds (rear - right). The tire appeared as if someone had cut around my rim and left a tubular piece of rubber. Currently I am seeking my insurance company for advice and repairs.

I purchased a new Infiniti 2007 M35x December of 2006 the car came equipped with good year rsa tires 245-45-18 after 15,000 the tires are totally worn to the wear bars front and rear these tires have been rotate at 6,500 miles and 13,000 miles. The car is unsafe to drive on the highway it follows the groves in the road, also in rain it is horrible and unsafe. Tire presser is at 33 lbs on all tires and all tires are evenly worn.
