Tire Presures ... Hot and Cold
I know tires have recommended pressures listed on the sidewall and always assumed it is the hot number. Is there an average rule of thumb as to the temperature swings between hot and cold. 5, 10 or 15...

All tires that states max PSI cold is 95 PSI then the maker of that tire/wheel knows the operating temps may be has high as 115 PSI.
Tire PSI is not rocket science.
If the MH placard states 90 PSI and the tire states 110 anywhere up to 110 PSI cold is technically fine. We now run closer to max sidewall marked PSI in the MH and all other vehicles.
IF you are running tires different than shipped on the MH be careful.
Our MH states 65 PSI but our current metric size tires MIN PSI is 70 and MAX is 95 PSI. When we park for the winter we air to 100 PSI and hope they are not below 70 PSI if we had to move fast. :) Airing to 120% of max is fine per most tire makers if parked since that is the normal PSI when traveling.
