Does anybody use a portable tire inflator?

Apologies for the poor photo quality. This is my set up. It locks on, so when I set the pressure I can walk away.

Remember heat, altitude, and barometric pressure can affect air pressure. Tires filled with “air” will slowly pressure over time due to the size of the molecules. Nitrogen is the go to, slightly bigger molecule and with the absence of air you won’t get the increase in pressure as the casing heats up. I’ve never seen nitrogen offered as a service for trucks. Depending on the cost I’d probably do that.

 

I don't know what the altitude difference is. But I know my superwides vary 15 between running hot and resting cold.

 

Tires can lose one pound of air for every 10 degree temp drop.

 

I have Milwaukee m18 that I carry in tool box, m takes a few minutes to go from 85 to 110. However doesn’t take longer than the hose.

 

I had a day off today and decided to try this tool. Took 15 minutes to go up 10psi.

 

Not to be rude but that's a long time.

Someone needs to try a dual cylinder pump.

 

Lol not taking any offense, it was interesting to try it out. This thing has long 12v power cord, I might just keep it in my car to pump up a ball when I go to play soccer or for a roadside emergency

 

I have one on all my vehicles. Including the motorcycle which also has a 12v socket. I also carry plugs. And tools for pulling whatever out of the tire.

The only drawback..as you've pointed out. It's time consuming. Even car tires. But it's better then nothing when you're miles away from a gas station.

 

Especially if the chicken coop is closed,,,for now

 

Maybe someone will come up with a tire inflator app and we can just hook our smart phones to the valve stem.
