The tire ratings are actually something I have a little knowledge on from when i had my truck, and Richie is right, the rating does affect the stiffness of the sidewalls and the amount of weight it will hold. When i got tires on my truck I had to get a higher rated tire because I was using it to tow heavy. I could feel in the ride that they were a stiffer, less forgiving tire over bumps.
So a heavy car on too low-rated tires may cause problems like he described.
