Re: questionable tires...
I'm not sure the weight of your vehicle matters...those tires are heavy duty! If you're getting the same mileage, there really isn't an issue. New tires don't = better economy. Proper inflation and less agressive tread = better economy. If the tire is heavier that could have an adverse affect too, obviously. But what's the cost? A few nickels at the pump could mean 10k more miles on those heavier duty tires.
