heavier trailer tires and fuel economy
I know heavier tires on your truck decrease fuel economy but what about on a trailer? Looks like once you get it up to highway speed it wouldn't matter? why I asked was I got tired of the blowouts ...

I run 17.5 MT tires rated for 6005 pounds per tire and wheel combination on my fifth wheel, wheels weigh 60 pounds each, with tires weighing 65+ pounds. I run them at max psi of 125. Actually get better mileage than the 16" tires they replaced.
