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.
You are WAYYYYYYY overinflated. You have less stoping ability and a **** rough ride.
60# ? what wheel are you using? I run the 17.5" Alcoa aluminum wheels and they only weigh 30# each along with the Continental "J" HTL2 Eco Plus 235/75 17.5 @ 65# each. My two axles have 18k on them and 105psi gives me lots of extra capacity.
EDIT: I see it's a gooseneck we are talking about. Still stand by you are wayyyy overinflated.
