What do you use on the trail to inflate your tires when you are ready to hit pavement again? I bought a 12v canadian tire special I am going to try out today and see how that works but I notice a lot of people use inverters and small air compressors and I am now considering that. I need to be able to inflate a 32/33" LT tire to 44 psi for the road from what ever I deflate the tires to for the trail probably 25-35 psi.

That small compresser is going to take a long time to fill your tires back up. I have a small air bag compresser for air ride suspension with a 4 gallon tank and its pretty slow. I just turn it on and leave it on so the tank is always filled up so you have that burst of air incase you blow a bead

I use a firestone compressor for air bags,alot better than your 12$ one that plugs in your lighter socket and will last alot longer.
Like youngun said hookup a storage tank[cheers]

I bought 1 many many years ago, and it still works for me! I lengthened the
power cord as i was useing it to inflate the tires on our Dodge MAXI Van that we used for offroad camping in the states,in the late 80/90s!l:) :)

i bought a battery boosterr with a air compressor built in and a extra air compressor from canadian tire so i can fill 2 tires at a time but still takes forever.

I found NSOR has a good selection will probably get a viaair. http://www.zoneoffroad.ca/default.cfm?fa=products&ProdCategoryID=157

Your truck must ride like a brick at 44 PSI for the street is a bit much don't ha think have u looked at your max PSI ?????

and 35 for the trails ain't doing you any good with either

I got a similar one like viair but from kms tools.
Works good on my 35.s but slow and gets hot after 4 tires....

Don't cheep out..... go for a quality one..... not cheepo that plugs into lighter. Get one that hooks up to battery.

tat is what i was thinking 25on road10off also the viaair is a great kit well worth the coin as long as u Get the one with a tank because no matter wat compresure u get with out a tank it will take a while to inflate a set of tires

lots of manufacturer specs call for higher pressures on the doorpost. doesn't necessarily mean they should be run that high all the time, but that's where tire pressure should be gauged from... not the tire sidewall. seen some as high as 80 psi on HD3/4 tons and 1 tons

but ya airing down to 25 would be better but not gonna make a huge difference.....

anyone made a pump out of an AC unit?

It doesn't and I run 44 because it grabs all the worn "ruts" from trucks on the highway otherwise and pulls all over. I ran 35 on my old truck but it was a smaller suv that would be a brick at 44 psi. As for trail I am new to airing down so I will probably play around with psi overtime and go as low as 15 but time will tell. Thanks for the information I am going to figure out the best compressor for my budget now. $200 or less is the target.

You should be able to find something decent for 200 no problem

As low as 15? That's highway pressure.

I use a stock ac pump in my jeep. Piped to a 2.5 gal tank under the body.
Use a good filter on the intake with an auto oiler. Outlet runs to a manifold with pressure switch , gauge and air chucks.
It will fill 4 35inch tires from 6psi to 30 in 10 min. I can even use the air impact and keep 100 psi in the tank.

This is one of my favorite topics.


IMO, A power tank is the way to go, sure you have to fill it up once in a while, but when you have 2000 psi, it takes a long time to use it. in Fact you can install a lift in a truck using air tools for a weekend and still not use it up.


The question that you need to ask yourself is, CFM or Volume (tanks).

Pressure is not really a problem as long as you have a minium of 120 psi.

Ok, so you want to convert an a/c pump, great....you should have a at least a small tank to act as an accumulator, Iif you are running air lockers its a must). A/C compressors have good FLOW (CFM), about 12- 22 on average.
Not so great for pressure, engine must be running, and require service and oils in most cases. need to be mounted.

Electric compressors.

They can run higher pressures, the flow is lower. A good one is only 5cfm at 100 psi...
You also need to look at the DUTY CYCLE.. There are cheap electric ones with low duty cycle. Need to have tanks !!! the bigger the better. They can be mounted anywhere, and run any time (as ling as you have a good power supply).

This is what I have in my 82'..


I have a firestone military spec %100 duty cycle .75cfm @ 100psi (I have run this compressor for over an hour in the summer before it actually shut down, then it only needed 5 min to start up again then ran for another 45minutes)

I have 3 tractor trailer tanks onder the bed of the truck.
I set my pressure at 175 psi, with a 200psi saftey valve.
Lots of pressure, lots if volume.

I am able to air up my Goodyear MTR's (37's) from 7- 20 psi, I have a beer, let the compressor catch up and air up to 25-30.

I also have an ARB so I regulate that to the required 80psi.

I would like to install a power tank system in my 97' 4runner.
