Tires rated for 95 psi sidewall - ok to run 80psi?

[Jhurk]

I purchased a 2009 Cardinal had them change tires as 8 yrs old. ST 235-80-16 were stock tires recommend 80psi for max load for rim of 3100 lbs. they changed tire and put on ST 235-85-16 max on sidewall of 95 psi and for load 3800 lbs. I went to,tire dealer to see if I could run them at 95 psi on the rims. They said run them at 80 psi and that would be fine good for 3200 lbs per tire. I had them put in steal valve stems and balance tires. Question is,would I,be ok with 80 psi. That is more tan enough for the weight so I,believe it would be ok?

Probably but the safe answer is to weigh it fully loaded and look up the mfrs recommendation for that weight then add 5 PSI.

Many tire makers publish load vs inflation charts. Lower weight on tires corresponds to lower required pressure. As long as those numbers correspond to their chart there would be no problem.

Yes.
