jimnlin is misinformed about steel wheels not being able to take 80 psi.
side bearing loads and the strength of the wheel being able to support a load are exponentially greater than tire pressure within a wheel .
further , when these rv or light truck wheels fail they do not do so catastophically .
rather they develop a crack at a "shoulder" and they fail because they can no longer maintain a constant pressure.
I never said a steel wheel wasn't rated at 80 psi. See my above post on different wheel pressure ratings.
I base my opinion on facts from the wheel makers and my personal and other operators experience of busted out or cracked steel wheel centers and split bead seat flanges from using the wrong capacity/pressure rated wheels and from and wheel dealers recommendations.
All steel wheels are stamped from different material thicknesses so one size don't fit all.
when these rv or light truck wheels fail they do not do so catastophically .
Busted/cracked wheel centers and busted valleys are not uncommon on LDTs out here in the real world. Now granted the vast majority of RV folks/persons don't carry max axle/wheel or tire loads so its possible that some could come to the erroneous conclusion that wheels don't fail or especially don't fail catastrophically. Wheels can and have failed from using the wrong capacity(s).
