Question The Ups and Downs of Air Inflation

I had so much fun on my first trail ride recently that I wanted to start getting my own gear. First on the list are Tire Deflators and an Air Compressor, but with all the options out there I wanted some of your expert opinions before I go out and buy junk or break the bank unnecessarily. What do you guys have and like?

Tire Deflators:
Seems like the Staun's ($73) are the best around based on reviews, but don't the Smittybuilt ($40) or Rugged Ridge ($35) versions accomplish the same thing with a reasonable level of accuracy? I also saw one post that said a dude with the ARB E-Z Tire Deflator ($38) aired down faster than anyone on a recent trip. It seems counter-intuitive to me that he'd be done first plugging away at a single tire at a time with the ARB version, but maybe not.

I was hoping to spend closer to $40, but if those models fail to get the job done well, then I'm not opposed to spending more money on the Stauns. What do you guys think?

Air Compressors:
I don't have 31" BFGs yet, but may in the future, and want to get something that could handle the load. I was hoping to spend < $100, and not have to spend more than about 10 minutes to refill the pressure at the end of the trail. I'm sure there are good ones I haven't found yet, but I was looking at the following compressors:

Smittybuilt ($75)
SuperFlow MV50 ($70)
VIAIR 85P ($50)

What do you guys think? Also, do I need one with alligator clips to the battery, or do the cigarette lighter varieties work just as well?

Thanks for the words.

I have the superflow MV50 and I love it. I paid 49.99 on amazon 1 day sale. And for deflators I got the cheap ones off ebay and they work great also, just put them all on then take a tire gauge and check them each then unscrew at desired pressure easy as pie, I think they were like 15 bucks on a key chain thing even

Thumbs up

That's two votes I've heard for the MV 50 now. Do you guys find that the pressure gauge on top of the compressor is accurate when filling up?

$50 Sounds like a good deal to me - I'll just look for it on sale.

I have found that the gauge on my air compressor is close but I pull out an actual tire pressure gauge to make sure. The extra 2 minutes it takes to check all 4 tires with something you know is accurate is worth it.

I use these to pull the valve core and use an electronic tire gauge. Takes just a few minutes to air down all 4.

Dextreme, those are different deflators valves than I've seen before. What are they and where'd you pick them up?

I use the Smittybilt deflaters and they work fine. I also have the MV50 and it works great. While the gage isn't accurate, it is consistent. I fill to a couple pounds over where I want then adjust it with an electronic pressure gage.

store mine in the center console, every time I try to use core remover caps someone walks off with em.

haven't had any reason to air down since getting MTR's though. the only time I lose traction is when it's sitting hard on the frame.

I really like my Currie EZ deflator (same thing as the ARB). It's really fast and simple. I also have the Master Flow 1050 which is pretty much the same thing as the MV50 and it works pretty well. The gauge isn't too accurate but it's easy just to check with a stand alone gauge. I think I got my compressor for $50 but everyone has since hiked up the price as they have become more popular.

Not sure if I would recommend a cigarette lighter powered one, just seems like too much current going through there or it would be really weak.

Another vote for the currie/arb deflator. I wouldnt say that it is the fastest...but its sure close to the top.

Another vote for the MV50 as well. I dont know whats up with my compressor gauge...you guys say its only a couple pounds off...mine is a consistent 15-20 pounds off haha. Doesnt change the fact that its a great compressor for the money.

I think mine is about 10psi off and bounces around when the compressor is on lol. Apparently there are some pretty cool mods you can do to this thing such as installing an accurate gauge, switching to a standard air hose, permanently mounting them places, etc.

Im not too worried about the gauge since I just double check with a handheld...but I can vouch for the air hose. I swapped mine out with 20 feet (I think) of the small diameter PVC hose.

On my MV-50, I removed the gauge that came with the compressor and replaced it with a slime gauge. I also removed the fittings and hoses and replaced them with standard 1/4" NPT fittings.

I use Stauns but I can't say if they are faster or better than others because I have never used anything else. I also have a MV50 which I will be hard mounting in the next week of two when my air tank shows up.

Thanks fellas!

Just ordered the MV50 for $60 from lowrangeoffroad.com and found the Staun Tyre Deflators on eBay for $50. I'll post how I like them when they come in.

I was planning to mount the compressor on the second battery tray but because I have cruse control the room is rather tight. I have to re-think the compressor location. The tank will be a viair 2.5 gal mounted just rear of the T-case.
