There are RV steel wheels that are stamped with a weight rating .
Some aluminum wheels are stamped with a psi limit .
Aluminum wheels , when they fail they do not do so catastrophically .
Aluminum wheels can develop a small hairline crack at the shoulder and these aluminum wheels simply will no longer hold air pressure .
Those failures occur do to usage and weight loading and are not caused by too much psi .
The myth that certain steel RV wheels are psi limited has been perpetuated on this forum by folks who simply don't know .
The strength of a steel wheel designed to support an 1820 # load rating is more than adequate to hold 80 psi and is not a design consideration in practical applications .
You know all this because?
Here is a picture of a Tredit T03 (I believe) wheel that came on Cardinals. These are 80 lb rated and were replaced with wheels rated to 110 lbs. Left unattended this would lead to rim and hub parting company.
