I have always (and will continue to) rotate, and balance, my tires every 5-7k miles. Every new tire comes with a manufacturer's mileage rating. If you purchase a 60k mile tire and it wears out at 30k miles, you should be prorated 1/2 of what you paid for that tire to replace it. If that is not what is happening, you need to shop for tires someplace else. Now, with that being said, if you never rotated or balanced those tires during the 30k miles you had them on your car, not sure how you can claim it was the manufacturer's fault they wore out at 1/2 of their mileage rating.
