Always wanted one. Got a cheapo, plastic 12 volt one (gift) years ago that I never even bothered to try.....doesn't go high enough, looks like it will just make me lose tire pressure!
Prefer to stay under $200.
For bumping my truck tires up 20 lbs for towing, and for maintaining trailer tire pressure, as well as household cars.
Doesn't have to have 12 volt, but that would be nice.
Whatcha ya'll using?
thx

Make sure you're using it right. Mine works fine up to 40psi. They screw onto the valve stem to secure it. If you don't it'll just deflate the tire

Victor, does your go up to 80lbs?
Most of what I've seen on Amazon looks like pretty much junk.
And too many will take too long to get to 80lbs, as in, you have to stop to give the compressor a "rest".
meh....
In some instances, I'll have to go from 50 to 80lbs for a truck tire.......don;t feel like waiting 20 minutes per tire.

Pretty happy with mine. The most expensive one from Harbor Freight. (Still cheap, plus wait for sale and throw a 20% coupon on it and good to go)

http://www.harborfreight.com/12volt-150-psi-compact-air-compressor-69285.html?utm_referrer=direct%2Fnot%20provided 

But, it's got a flaw. The thermal overload switch is unreliable. I bypassed it. Wouldn't try to fill 4 tires all at once, but it'll top off my rears and the trailer tires before I leave the racetrack or campground.


Edit: it's too slow for what you want. Not gonna get much better in the 12v range though.

Before I bought this, I kept a small pancake style 110v compressor with me for camping or racing. Already carried a generator where I wouldn't have 110vac.

Thanks Dan. Been looking at a dozen or so similar ones on Amazon, many from ViAir and the like.
Just too many choices.
Don't have a generator yet.........but a Honda 2000i is in my near future.
If I had the generator now, it would completely change my choices......

I have been using this kit for years now and have repaired quite a few tires with it. It also has enough power to pump up the big tires on my truck and is still a small size.

Even the off brand inverter generators are good these days. Unless you need the tethering for a 30a, can go cheap on em no need for the gold standard.

I've tried 3 different 12v pumps, 2 before the one I posted above. Used them when I was a mechanic for on board air in my cramped service truck. Had bag helpers in the rear, so I used em for those and any other tire filling on machines n stuff. The cheaper pumps didn't like filling the 70psi truck tires but did fine for utility tires n stuff. Took ages for anything over 50.

Well, I ended up getting this one.

Should be here in a week or so..........Ill report as to how good, or bad it is.
Generator is next..........still leaning toward the Honda 2000i......they are quiet compared to anything else I've seen in action........and I've seen lots.
Too bad they're so spendy, but ya get what ya pay for.

True, depends on your need. The 2000 is quieter than a dang toaster. But for the 1k÷ price difference I'll take a cheapo that sounds like a desk fan.

Try and find the PUMA 12V air compressor. Comes with a tanks attached. The thing is a powerhouse. I have one installed in my Jeep for OBA. It's a standalone unit and comes with bare wire ends so you can hard wire it or attach cables with battery clamps with a quick disco. Thing inflates my 35" tires from 12psi to 30psi in about 2 minutes per tire. I believe it's actually a 1HP compressor. It's the closest thing to having a York OBA system installed in tandem with the engine. 1.5 gallon tank attached. 100% constant duty, which means you don't have to stop and wait for it to cool down as often. It's rated at 3.4 cfm at 90psi. It's a total workhorse. I'm extremely happy with it. Hope you check it out. They also make a 115AC version.

As promised - a quick review


Viair 00088 88P Portable Air Compressor

https://www.amazon.com/Viair-00088-88P-Portable-Compressor/dp/B005ASY23I/ref=sr_1_1?s=automotive&ie=UTF8&qid=1472751027&sr=1-1&keywords=Viair+00088+88P 

From Amazon - $65.95, free delivery

Looks well made, (see specs in the link)

The Good
-Price
-Threaded connector for tires, and accessory adaptors
-Very compact and light
-Fairly quiet.....but then my truck is idling...so, the truck is much louder than the compressor.
-Decent power. Inflated my truck tire (245/75R-16) from 55lbs to 75lbs in 2 minutes and 30 seconds.
-45% duty cycle (run for 4.5 minutes, rest for 5.5 minutes)......that's good for these types of units actually
-Nice little add-ons for balls, rafts, floaty toys, etc.

The Could-be-Better
-Fairly hefty vibration from unit, causing it to "wander slightly" when on concrete, despite the fact that it has rubber feet. (Put it on a towel and the wandering stopped)
-Unit takes a good while to cool down after use
-No 110 option......that would be convenient....but probably drive the cost way up.

The Unknown
-Life expectancy......I'll be using this fairly regularly.....if it lasts 5 years.....I'll be happy.

Came back to look for this thread because the discussion came up on my racing forum and the VIAIR pump was the winner there. Looks like you already found that out.

Um... I have 265/65/17 on my truck. The rated pressure for my tires is 33psi. Why would you be going from 55 to 75 psi?

Just curious... my trailer tires call for 55, but that seems excessive for a truck with 16" tires.

It's about towing.
My trailer is 5000lbs plus, my tongue weight with my WDH installed 600lbs plus.
I'm 11,000+lbs total.
My max pressure rating is 80lbs. Using the traditional tire pressure tow formula as a guide, I've decided to run 75lb+ on the rear and 70lb on the front when towing, and 55/50 when not towing.
The truck does NOT like towing the trailer with 55lbs in the rears.

Thanks for the lesson. I usually keep my truck tires at 35 psi. Can you post a link to the tire pressure tow formula? I'm interested to know if I should be bumping it up. My trailer weighs about 3600. I have no idea what the tongue weight is, TBH, and I am just guess-timating at the total trailer weight based on what I was told... never weighed it.

I know my truck doesn't like steep hills, but that's likely because it's a 4.0L V6.
