Tires, what are you using? Trailer? Truck?

I also disagree that all steel tires rated for 110 psi aren't stronger than E rated tires. At 80 PSI, they're technically rated for the same weight, but that doesn't tell the whole story. All steel tires are tougher in every way.

With a little experience you soon learn the cons out weigh the pos of derating a very heavy all steel carcass load G tire on a trailer to 80 psi.

I also haven't heard anything bad about the Goodyear G614 all steel tires, but they're $320 each and there are no discounts to be found anywhere.

JFI......the Goodyear G614 have been around for years and had a very bad service record till '09-'10 era . Goodyear re engineered the tire and its enjoying a much better reputation but complaints still come up time to time on rv and non rv websites.....but nowhere near the volume pore'10 era.
Anywayz...keep those new tires pumped to the max sidewall pressures for best long term performance and max reliability.

Was this in response to me? What do you mean by "derating"? A G rated tire at 80 psi will support my trailer loaded at its complete GVWR. At its unloaded weight, an E rated tire would support the trailer at something like 60 psi.

Although I would never deliberately operate something outside of its operating parameters, I am kinda skeptical of wheel PSI ratings. What's the difference in a wheel rated for 80 psi and one rated for 120 psi? I don't know what my wheels are rated for anyway since I haven't pulled them off yet, but color me skeptical that there'd be any harm in airing up one's tires beyond the wheel's pressure rating. I'm confident that a steel wheel is way stronger in every direction than the rubber tire it holds. I wouldn't be confident that the same would be true for loading it with more weight than it was rated for, though.

I went and checked mine, and I also can't find a PSI rating anywhere!
