Dangerous assumption simply because you haven't seen this issue which is actually pretty common out here in the real working world. "MOST" RV folks understand the danger over pressuring and over capacity numbers so it not as big of a problem on a RV web.
Trailer wheels come in pressure and capacity ratings.
JJ gave part of Dexstar trailer wheel capacities/pressure rating. Here are some more .

Notice the last trailer wheels. Two different wheels with the same 1820 lb capacity but one has a 50 psi and the other has a 75 psi. There are reasons for the difference and its to everyones benefit for them to find out why.
