Tire Pressure Recommendations
I have a 2019 F250 with the Michelin tires. What do you guys run air pressure at in these tires when not towing? Also - when towing a 10,000lb Travel Trailer?
Just looking for some wisdom on this!

When not towing, you can drop pressure some, but if you go too much it will trip the TPMS light and warnings.

I tow my 10000 lb 5th wheel and use the sticker ratings, 80 for the rear and 60 for the front. The trailer tires also run at 80.
When I'm not towing i drop the rear to 70 if I get around to it, but I tow often so it's not a big deal to me to run at 70, keep the front at 60.

I run 60 front and 55 rear when just driving. If I tow, I will bump up the rear depending upon what it is. I adjusted my TPMS on the dash accordingly so I won't have a low pressure light until 50 front and 45 rear. You will also note that when you change the thresholds for a low pressure warning, those figures are now listed as recommended cold pressures on your FordPass App.

Tell us more about your truck, especially Diesel or gas. What size tires are on the truck, and what tire size and inflation specs are stated on the load label on the driver side B pillar?

Google "285/70/18 tire inflation table", using your tire size. The table will show you how much weight you can carry for your psi level.

My 250 sticker suggests 60 front, 65 rear, I run 55f/55r empty. There shouldn't be any reason to go higher than the sticker pressure unless exceeding the F-250's rear gawr.

my door jamb states 60 up front and 65 out back
i run 65 up front and 60 out back when empty
towing i adjust PSI based on load transferred to rear and front axle,
tire inflation tables at the tire company websites are your friend

Uh, that is why you see some have posted they run lower than the sticker unloaded.

55psi all around, even when towing. Trailer has 1200lb tongue weight. Even with that, and some items in the bed, I'm within load spec at 50psi. Added 5 psi on top of that got good measure. 7.3L gas. Rides much better.

i will add
the best PSI setting should be a few things
a flat or even contact patch across the tread, EMPTY or normally loaded
easy to check on a flat slick surface where you can visually lay on floor and look at contact patch or its transfer to the pavement.
or you can get a IR temp gun and read temps across the tread once tire is up to temp. measure at both edges and center. if they are the same then your probably pressurized correctly for the current load
and use tire manufacturers recommended PSI for set load on the tire
but most will set a pressure and never adjust. its all about what makes you feel good or happy,
i use 65 up front becasue 60 felt entirely to squishy so i adjusted up incrementally and found 65 worked best for my current conditions for my truck
same out back 65 was way to hard and i adjusted until i found a good balance which was 60
the fact folks are actually checking the PSI is the right thing to do to be safe and get good wear

My 250 ccsb 6.2 I ran at 60psi all around and that seemed to work well in terms of ride comfort and carrying capacity. That was on 275/65/20’s.
My 250 ccsb 6.7 I’m running 70psi all around. The 21 rides better than the 16 to begin with so it’s tough to compare apples to apples but I think 65psi all around will work too for a good balance between comfort and carrying capacity.
