"Proper" PSI??

[JJEH]

What is labeled on the tire is the MAXIMUM allowed air pressure for when the tire is carrying is MAXIMUM recommended load.

Indeed.

Likely, since this is a 5th gen (2019+) forum...

Well scuse me mate lol I just click on new posts and this just showed 'general discussions'
Regardless my advice stands, lower your rears unless hauling or towing.

Never go by the door sticker, always go by what the tire says!

With that being said, current vehicles are 50 PSI (car) and 70 PSI w/o trailer and 80 PSI w/ trailer respectively for the RAM (unless I'm stuck in the sand), all with Nitto tires.

Always measure cold if you can.

Problem is the max psi on the tire is at max load, my tires recommend 51 psi but that would be ridiculously high for running empty. Your tires will let you know, watch the tread wear over time.

OP asked about everyone's feelings about proper PSI. This is how I do it and I never had an issue. I've got stuff in the vehicles and I don't have to worry about having passengers or towing. I check once a month and car usually goes down to 40 and truck to 60, no issues here.

Tires on our Durango lasted over 50K miles, RAM has currently 45K with them tires, our car around 30K.

I kept the tire pressure on my 2011 Bighorn with factory 20" wheels at 40 psi. I havent even looked to see what my 2021 bighorn shows yet but I will more than likely keep those at 40 psi as well

Maybe hijacking a bit - Remember to check the pressure in your spare, at least once a year. If that thing is flat, or nearly flat when you need it, it will add more frustration to a crappy situation.

when i'm offroading i drop 10 psi all around.when i'm carrying/towing i add a couple psi.otherwise i add till it's comfortable.that's the great thing about tires,they're adjustable for the applications.anyone with a sidexside/atv gets it.

That's the pressure I run on my 2003 Dodge Quadcab.

No, No, NO!!!

The number on the tire is the maximum amount it can sustain. The tire has NO idea, whatsoever, what vehicle it's going on.

You MUST start with the door jamb number unless you are desiring to die a fiery death.

OTOH, as long as the tire number is higher than the door jamb number, you will probably be "safe" but most likely wear out the tires before their time and have a much rougher ride than is necessary.

haHaHAhaHAAAA

Good practice? NO DOUBT! But unless I'm traveling the AlCan, I will defer to AAA rather than that...

Yeah, okay...

I agree there. As a former mechanic I grew sick and tired of people telling me I had under inflated their tyres after service as they were setting pressures from undo on the sidewall.
stick to the reccomended and you can go wrong

Look guys... 1st of all I posted in the wrong section, I don't have a 2019+ RAM

Second, tire pressure question is a very personal thing and it comes down to "what works for you" really. Ever participated in discussions about "best" motor oil, "best" firearms cartridge, "best" tire, "best" whatever? Yeah, it's like that.

It's great that people defend the door sticker, saying go with factory recommendations because the tire doesn't know what vehicle it's on.
Great. Neither does your sticker know what tire is on the vehicle.

I don't even have 70 in my RAM tires... that's how I started out. It's between 60 and 65 in all reality. The car is the same... it usually is between 43 and 45. And you know what? It works for me. And if it doesn't work anymore, for whatever reason, I'll change it.

No one knows other peoples load conditions, terrain, driving style, etc., so it's really hard to give an ultimate answer because you just have to figure it out for yourself.

But I agree, the door sticker (if the tire size is the same) is a good start, then just go from there.

It’s a very personal thing. What you do with your tires is up to you .

AlCan...Hahaha, wait times for AAA where I live can be a number of hours. There's no way I'm waiting for any length of time just because of a flat tire. 10 minutes and I'm back on the road, versus a 3 hour wait for them to get to me, then another 30 minutes once they arrive. No thanks LOL.
