Having had my share of trailer blowouts years ago because I wanted smooth ride in the truck and trailer I did a lot of investigating and talked to Goodyear, Michelin and others - dealers and factories - and also on here. Blowouts came from under inflated / overheated tires.

Consensus among the tire people and most people on here was run at max on the tire. If there go over that when warmed up, they are built for it. And we run in some very warm temps.

So, mine are checked regularly (not every day) at ambient temp before I take off. Carry my own 120v / 140 max psi compressor (need 110psi for the trailer tires).

I also have air hitch and air ride on axles on the trailer; not on the truck. Check all that as well.

Knock on wood, no blowouts for 6-7 years.

BTW, you will most likely get all kinds of answers on here. I did before I went to the source.

So in your mind a tire rated at 3,415# at 80 psi, is not overinflated when carrying only 1,450#? :h

Which profile will that tire at 80 psi, with only 1,450# on it look like??
