Portable tire inflators?

This is the way I went after the cheap truck stop ones break. Go to truck pro and get a universal glad hand if your red line has the little knob towards the end. Buy a good quality rubber hose. I’ve been using the same one for 6 years.

 

Portable tire inflators are adequate for small car tires... They don't have the duty cycle to inflate anything more. They start getting hot and will start taking internal damage after 10minutes or less, at best. Anyone that has one? It's should be in the owners owner's manual.

It takes close to 5 minutes to pump 10psi I to a truck tire (pickup truck), by then it's time to let it cool down. Ouch.

Don't do it, it's a trap!

 

Every now and then, I pay 5 bucks (10 if I decide to do the trailer too) for a cold tire inflation after I overnight at a Loves with a Tirepass.

They have 18 air lines at a Tirepass lane. Far easier and faster than topping them off myself one at a time.

 

The tractor trailer has a compressor already. Just unwind about 60 feet of hose, attach a auto cut off set to a poundage and stick it.

Now I use a small 120 volt air compressor to get my tahoe tires up to 40 PSI, they generally have nitrogen inside of them which is very good (N2 is about 70% of the atmosphere we live in anyway, 20% oxygen etc)

Ive not had to feed my tires often and don't expect to until summer.

 

I use the glad hand tire inflators they sell at the truck stops. I set my truck to idle at 900 RPM, and it takes 45-60 seconds to inflate 10 PSI. I’ve done this many, many times. Use a stopwatch on your phone to find out how long it takes to inflate 10 PSI, and then use a timer to know when to stop. It also helps to pump/push the valve core once or twice to clean the valve and have a good air connection. Otherwise, it will take longer to inflate the tires as the valves won’t be fully opened.

I’ve tried using truck stop tire inflators at the pumps, but I got sick and tired of them. It’s very common for them to not work or have the wrong inflator adaptor, so you wouldn’t be able to inflate all your tires. My glad hand inflator, on the other hand, always works. It never fails. I’ll take slow and reliable every time.

 

I plumb quick couplers directly to an air tank on my trucks. I do this so I can air them up with shop air, so I don't have to let them build up air inside the shop, but it works great for airing up tires or running an impact. More volume and pressure than off the glad hand.
