No, no, no...just no.:S

So if one tire on my dual axle trailer is flat, I should inflate the other tire on the same side to 160, right? The two of them average to 80, which is the recommended. I would be good to go without changing the flat!

Not really sure what your comment has to do with my comment, nor have I seen anyone saying to "average" tire pressures. However I will clarify that my "no, no, no..." comment refers to motorhomes (which is what the OP was asking about), not trailers.

A tire is not specific to any particular vehicle, and the tire manufacturer has no control over what vehicle it is installed on. The pressure on the sidewall applies to the max load the TIRE is capable of carrying, NOT the specific vehicle it is installed on, which is why load tables are published, and which is why ALL vehicles, including RVs, have a Federally mandated tire pressure label on/near the driver door. Simply inflating the tires to that max pressure on the sidewall will almost always result in a hard ride, uneven (centered) tread wear, and diminished handling/braking.

It was a joke.

Grit dog...

" check tire age on a 2021 unit to see if they’re over 5 years old."
You got me, my bad for not catching that the OP was talking about a 2021.

My old boss used to tell me:

"If you are going to read at all, read it all"

:S

Let me count the funny’s in this thread and it’s only on p2.
-Towing a mho with a ford ranger.
- check tire age on a 2021 unit to see if they’re over 5 years old. (And even more ridiculous is assuming heavy truck tires are aged out by then)
-use the tire pressure on the tire
- worry about individual corner weights. (This is the least silly of the Silly’s but unless there is a gross difference, it’s a non issue. But Icbw here. Are mohos often loaded real lopsided?)

when loaded We will be towing a Ford ranger.

Have not a clue and anyone who does.. Except as described below. Do not listen to them.

How to get a clue.

First start with the manufacturer's recommended pressure if you can find it or anything close to (But below) the MAX pressure stamped on the tire... IE 100 PSI if the tires say Max 110.

Now find a scale.. You need a FLAT segmented scale

Loaded for travel Full fresh tank, empty waste tanks. Park so eachaxle is on a segment and get the axle weights. now pull around agains so JUST one side is on the scale and get the "That side" weight.

Now subtract the "Side" from the Axle to get the other side.

You should now have 4 weights Right and Left Front Right and left Rear.

Go to the tire maker's web site and find the weight chart for your tires.. I like to go 5 PSI over recommendation from the chart.

NOW Some folks say "All tires on an axle same pressure"

I DO NOT agree with that .. Each corner may be different.

And Duals the Inner and outer are the same.. NOTE however they have a DIFFERENT part of the maker's pressure chart.


Option to the above: go to https://rvsafety.com/

And to to the obvious link (Weighing your RV) at the top.
Small fee is worth it. They contact you (Have make, model and size of tires handy for when they call) and do all the "legwork" they come out with protable scales (Like the "diesel smokies have"and do a bunch of other stuff as well...Really nice folks.

Once again, I am reminding people that those load/inflation pressure charts are MINIMUMS, NOT recommendations.

I use the pressure noted on the tire, not the pressure printed on the vechile.

"To really set it right you need to weight the RV fully loaded and get axle weights. Then, look up your tires on the manufacturer's load inflation table and inflate to the pressure for that weight. "

Yep, using the sticker and blindly inflating to the max on the sidewall is a very bad idea. Also, how old are the tires? Check the DOT codes and if they are 5 years old or more plan on replacing them soon.

Good luck.
