That would be the same at higher altitudes as well correct? Where atmospheric pressure is lower, so it would take longer to air up at lets say 14,000ft compared to Denver at 5,400ft

 

It's the opposite because the air pressure we measure with our gauges & TPMS are measuring relative. Since the atmospheric pressure is less at 14k, you'll need less air to get to a higher pressure.

Atmospheric pressure at 14k is less than Denver is less than sea level.

So if everything were constant in the Pv=nRT equation (Pressure * Volume = constant * another_constant * Temperature), the measured PSI (or bars if you're a weirdo) will be increased at higher elevations.

Keep in mind that temperature is the likely variable when you measure air pressure, which is why you should be consistent about it. Don't compare your pressure you measure in the morning, parked in the shade after the truck has been sitting all night to the pressure after a highway burn to Moab at the gas station when you arrive.

 

Hey guys,

I have reached out for extra hands before so I would like to take the time to offer my set. I am planning to be home in the springs this weekend and doing some smaller things on my truck so if anyone else is planning on working on their truck and could use some help, let me know and we can make a day of it.

Happy wrenching!

 

My arb gauge and tpms are like right on. I’ll have to check against another gauge.

Would be nice if they auto zeroed when they read negative numbers for a period of time. Or if you could actually program 5 sensors.

 

If you want to split hairs you could say it would take longer to air up at altitude. The air pump is pulling less outside air with every revolution, so performance would be reduced. However the volume of compressed air to reach a desired PSI would be less, due to the lower atmospheric pressure outside of the tire.

Does that mean anything about anything....no. Just trying to stir the pot

 

You forgot to toss in a Rapidly Falling or Rising Barometric pressure

 

What, when the Moon is full and Jupiter is regressing, you'll DIE!

 

What is this “Air it down” that you speak of?












I could not resist.

 

single digits or bust

 

FTFY

 

Been going down to 8 psi for years and not broken a bead yet


Guess I don't wheel hard enough

 

My other truck I would go down to 3 or 4. Truthfully I never even used a gauge. As long as the rim wasnt sitting on the ground I was good. I measured it by if there were 4-5 lugs touching the ground, then I was good. Never lost a bead either and I wheeled plenty hard.

 

You don't wheel hard enough until you bend a spindle like @bot102

 

I mean it's possible I have bent spindle and don't know it


haven't had the truck aligned in years but it still drive straightt ish

 

@bot102 how is my alignment

 

Please hurry

the FB market flakes are driving me nuts about this one.

 

All the talk of air pressure reminds me I have a question about air returns for my basement remodel. I'm splitting a large basement area into 2 rooms and wondering if they can share an air return. It's a shared wall and would be the perfect spot for both rooms to have an air return. There is also another spot where I could also tie into an air return for a room right above the new room.

Can I share a cut into the main trunk line or do I need to add a new one?

 

Here's your single digits

 

I was going to go ahead and have my 30k maintenance (diff/transfer case fluids) done at the dealership. Price doesn't seem outrageous-$265.
But then they came to tell me that, because the skids are aftermarket (RCI), it would be an additional $150.

Is that a thing?
