"LT" tire pressures on Expedition
I moved up from "Heavy Load" tires on my Expedition to real "LT" tires. Max air pressure on the new tires is 80#, max pressure on the heavy load tires was 50#. I always ran my other tires at max press...

Also, not scientific, but general industry liability assumption....Yes ALL mfgs look to shave costs to increase margins, AND recognize liability as a big part of the risk matrix when designing a component or an entire product.
Tires and wheels get abused to no end, by EVERYONE, intentionally or not. And they're one of a few major components of a vehicle, that if they fail, at speed, have a high likelyhood of the literal fiery crash. Add axles, springs, brakes and steering components into this. No one dies if the AC quits working at 80mph. Someone does if the tire quits working at 80 mph.
Based on this and my previous post, there is a large factor of safety built into tires and rims.
Something to think about.
