I learned, some time ago, that if what I want to post does not contribute positively to the conversation, or does not impart knowledge, then perhaps it’s better off not posting.

Example of non-contributing post above .
If you are referring to Pvt’s down-puttings, you are correct.
I use one of these. Seriously
It has two nozzles, one that fits schrader valves and one that fits presta valve stems. I needed it to inflate the tires on my road bike to 100-120 psi but it works quite well on car and motorcycle tires. Completely inflating a flat car tire is a bit of work but doable, but just topping off the pressure every other week or so, is not that much work.
I kept it in my car.

Manual tire pumps do work great.
OTOH in this day and age how many people do you think would even consider this a viable option. I mean, from what I see there are just too many people that consider using a keyboard daily exercise, climbing 1 flight of steps excessive, and manually changing TV channels over exertion. Manually pumping up tires……Fugetaboutit.

I know what you mean. I’d go for a long bicycle ride more often if it wasn’t for the bother of having to pump up the tires. I’ll just drive to the gym and circle the parking lot for 15 minutes to get a parking spot right in front of the gym.

Ditto here on the standing pump!
I work in second hand, and consider myself quite lucky to have scored one just like yours - they are snatched up as quickly as I bring them out to the sales floor.
Saves the aggravation of having to haul out my Slime digital inflator, plug in into the 12V outlet, just to add 1-2psi, vs helping my IT friend, who oft lets his tires lose 10-15psi between adjutstments…!
I use a pump like that yellow one, but only for inflating bicycle tires. I’ve always used my shop- compressor for inflating car tires. I’ll give the bicycle pump idea a try next time I need to top off one of my car tires.
I expect @Bing’s comment above wondering why more car-owners don’t own a compressor isn’t so much about inflating tires as just the general usefulness of having a shop compressor at hand; e.g. for running an air tool, for blowing debris out of passages and blind holes, etc. Last time I used mine was to blow cobwebs out of the innards of a antique typewriter I’m in the process of restoring.
Not everyone has the luxury - or space or provisions - for a shop compressor.
I applaud everyone, like myself, who has the foresight to keep a small 12v tire pump, and/or a bicycle pump, in their trunks or cargo areas. No longer must they rely on finding a garage or gas station with an air pump.
If I was in the position of someone with a full service shop compressor, I would still respect, and not look down, on others who all they had was a pump of some sort in their trunk. It demonstrates their ability to think for themselves and take care of their vehicles.
Actually I have three, bought at different times for different reasons. The pancake I bought for using a roofing nailer off site. I have a little one that is easy to carry around that I use to blow out the smoke detectors once a year. The main one doesn’t get moved much and connected to my pipes. I understand no room.
I also have “Three” but not the same as Bing’s…
The Big Sears Compressor comes out once a month to balance the 5-vehicle’s tires: the Ram Truck, three cars, and a motorcycle (a total of 22- tires…. (includes the spares…). The hand pump and the foot pump come out as needed for 2-bicycles, the hand-truck, and the wheel barrel.
I always drain the compressor’s tank after use so it’s empty for the occasional bike tire or whatever…
It was not until I was writing this that I remembered that we have a battery operated Stanley Power Station with Air Compressor and Battery Jumper that is in the Travel Bag.
Our Travel Bag is really a sport bag that we toss in the car whenever we travel outside of town and it contains the Stanley, spare flashlight, solar blankets, water bottles, matches, snap light sticks, flares etc… in case we have a breakdown and the we just happen to be in a cellphone dead zone…
As for folks who do not have a garage or shed to store a compressor, I highly recommend the Stanley, it’s powerful enough to inflate the Ram 2500 Light Truck Tires (rated a max of 80-PSI) that I normally run at 65 PSI… And I even jumped the Ram once, it has a Diesel and it uses two 750-Amp Batteries for normal use…
Just out of curiosity, what cold tire pressures does Ram itself specify for that 2500 truck?
The 80psi is a maximum specified by the tiremaker.
What’s the recommended tire pressure for a Ram 2500?
For the 2019 to 2022 model years, the recommended tire pressure can range between 60–75 psi for the front tires and 60–80 psi for the back tires . One of the selling points of the Ram 2500 is that you can configure it in many different ways, so the recommended tire pressure will vary depending on the year, trim level, and the tires your truck came with .
The best way to determine the recommended psi for your original tires is to check the decal that’s located in the door jamb on the driver’s side of your truck.
But keep in mind that this is for the factory tires, and if you’ve changed yours out for something like off-road or snow tires, the recommended psi might be different. Make sure you know what the proper specs are for your tires, and be aware that the number you see on the tire isn’t the recommended psi , it’s the maximum one.
Here are some ranges for the recommended Ram 2500 psi ranges for the past decade:
| Model years | Front tire pressure | Rear tire pressure |
|---|---|---|
| 2019-2022 | 60-75 psi | 60-80 psi |
| 2016-2018 | 60-75 psi | 65-80 psi |
| 2014-2015 | 55-75 psi | 65-80 psi |
| 2012-2013 | 60-75 psi | 60-80 psi |

I have a 3.5 horse cast iron cylinder compressor I have owned since about 1985. I replaced the air tank about 20 years ago with a huge industrial tank from a industrial second hand store. That tank is rated to 160 psi working but never sees more than 120 psi.
Air tools were so incredibly useful and being able to fill tires is a bit overkill for it. It is big enough to run my spray gun, too. Battery tools have gotten so good over the last few years they can take the place of many tasks. My jump packs have had compressors that top up tires very easily. Still can’t paint with them, though. 
So ranges are provided, given that the loads carried may vary widely.
And they’re not just for the ‘factory’ tires - they’re for any tire that matches the sizes on the truck’s tire and load placard The common misperception is that once you change the brand of tire, the info on that sticker goes out the window. Nope. It’s still valid.
My trailer tires need 60 psi.
Yes, 80 PSI is the Max recommended by the tire manufacturer and I run front and rear at 65 PSI. Dodge may recommend 80 PSI but at that pressure, the hyper-stiff suspension makes for a very jolty (rough) ride. Here a a photo of the trucks recommendation label. It is a 2001 Dodge Ram 2500, Diesel, 4x4, Short-Bed with every “Bell and Whistle” option, except the Snow Plow Package I bought it in Tucson, AZ…)

The manufactures certification label only shows tire pressure for maximum load.
Dodge trucks came with a supplemental chart showing light load and maximum load pressures. This was included with the owners manual, which everyone lost.
I kept a copy in my toolbox, below is page 2 for the 2000 model year.
I’d probably run 15psi below what’s on LoudThunder’s build sticker, front and rear, and call it a day, taking into consideration the wide range of pressures listed on the page shared by Nevada_545.
Front: 50psi, Rears 65.
That would be a fair compromise for the couple of days per year I carried a full load, or even close to full, if I owned one of these Rams.
