PSI question

[MAMalody]

Hmm. I have 80# rims and they have worked great with the tires I have normally used which are E load range with max inflation at 80#. Last long trip I lost a tire and replace the tires on an axle with G load range rated at 110#, however, I only inflated to 80#. Setting other issues aside is there any safety issue here? I don't see one, however, I don't fully understand some of these issues.
