I believe you should have a load inflation table from your tire manufacturer, properly weigh your rig and then inflate your tires to the appropriate pressure based upon the manufacturer's recommendation.

This is a simple truth. Tire manufacturers do not set recommended (correct) tire pressures. Vehicle manufacturers do. So the correct recommend tire pressure for your tires is found on the vehicle's federal certification label for all original equipment tires and any replacements that are the same size and design as the OE tires.

That is a CYA number and you know it!

Weigh your RV fully loaded, all 4 tires if you want. Use the tire weight/inflation guide and add 5psi. Per GY tech support if you have changed tire sizes or load range. They could not say to change what is on the RV for pressure "CYA" again. But let's use some common sense here!

They usually put tires on RV's that in reality add up to Max tire weight rating.

If you are one to add very little weight to your RV or have changed tire sizes then please weigh your RV and use the charts.

Same goes with your TV.

At this point of time in this particular forum all I can do is point out industry standards. My posts have been disparaged so often that anything I say must be “BS”.

Here is a reference from a well known tire manufacturer. Read it carefully. They will not use any tire pressures lower than the vehicle manufacturers recommendations. This is just a single reference. I can post others from other tire manufacturers just as popular as this one and from what many consider the top of the line manufacturers.

Tire inflation charts are a tool for experienced tire technicians and others that know how and when to apply them to the trade.
