I run mine at 85 cold. But that is per the manufacturer's chart after loading my rig and weighing it. There is no "blanket" PSI, it can be different on every MH.
Mine also rise 10-15 depending on the ambient temp. If it creeps up to 90-100 outside they get closer to 100 PSI or even more when driving. Temps in the 70's pretty much go to 95 and stay there. Front may be a little more than the rears but not much. Temps on the tires are usually about 10 degrees higher than the ambient outside temp. Exception is left rear outside which sits next to the exhaust, it usually runs a few degrees hotter than the rest - curiously no higher PSI so my TPMS could be reading too much exhaust temp and not exact tire temp.
