Tire pressure when hot.

Pressures seem to indicate that the truck was heaviest on the drivers side, front, that's what you get for driving with a fat chick in your lap.

Barely enough room in a Mav to drive with a chihuahua on my lap!

They didn't teach you Boyle's Law in school up north, eh?

34 cold on all four of my factory Michelins gives me a hot psi of about 38 when It’s 95 degrees.
the side that’s in the afternoon sun will run 2 psi hotter than the side running in the shade.
On cool 68 degree mornings 34 gives me 35-36 psi once warmed up but still show a one degree difference on the sun side.

Set your cold psi and forget about it.

FWIW my on board tire pressure monitor tells me I got 35 front 34 rear when I set all 4 to 34 with a digital gage.

Having a new-to-me Maverick, I am playing with all the gadgets, tricks & doo-dads, and it seems that given the temps here in Birmingham, AL, the tire pressure only goes up by about a pound when the tires warm up--even on mid-to-high 90s days.
According to the sensors, that is.
Before I aired my tires up to recommended pressure, my app said high 20s psi was normal...what's considered low?

Personally myself I would have mine @ 32-35 cold. It all depends on peoples usage. The hotter the temp gets outside the higher the psi goes up, specially when driving for a while. P.S., Welcome, see you joined Aug 11/25!

Expect to jump 2PSI itself, 35PSI cold jumped to 37PSI when hot
I like to running at 35PSI cold

Yep; I aired my tires to 35

That looks so cool in Spanish!

Since you say it's in the app - please take a screen shot to post.

I'm very curious what exactly was saying high 20s psi was normal.

Sorry, but that was before I aired up the tires. :/

I know!

I was reading somewhere that all TPMS are the same and they won't actually give you a danger warning until it's under 24 or 26 PSI or something.... basically low enough to derim the tire.

My 2013 Taco TPMS was way better than our Mav’s
It was user set-able .. I’d set my tires at 34 and Hit the TPMS reset it would go off if a tire dropped four psi.
If I set the tires at 38 psi and reset the TPMS the system would alert me at 34 psi.

BUT ! It wouldn’t tell me which tire. Back then we had to be capable people. And check all five.
Btw guys would forget the spare. The system fired up the complainers

The pre-compulsory system in my Chrysler was a huge pain in the ass, theoretically you could set it but it kept reverting to default. Default was like 1 psi down and not many psi high. Add to this that the batteries used in the sensors had no voltage below -5C and it yelled at me all winter one way or the other.

I kept going in circles trying to find replacements, places will promise "universal" TPMS, Chrysler, yes, minivan, yes, alloy wheel, yes, 2002, ummmm... no, of course not it's a unique friggin' system. Also there were a set that COULD be programmed for it, but it needed the $5000 machine so the places that had one were trying to amortise it over like 10 customers.

Ah the old days when all we had was a gauge, and not even digital at that. Air pressure pushed that stupid slider out, so accurate!
