I'm having a strange problem. I figured out how to use my tire deflators and have them set to air down to 19 for the front tires and 25 for the rear tires. Front tires are great, they air down to a perfect 19 each time. Something is funky with the rear. I get them set to 25 and it comes out perfect on the drivers side rear tire. Everytime I air down the passenger rear tire, the same deflators take them down to 20. I have repeated this several times, air both rear tires up, adjusting the deflators again, and the same thing keeps happening. The valves appear to all be the same. My tires are all cold, have not driven rover today at all. Any ideas???? Thanks, Jamie | ||

Hi Jamie, I'm guessing you got a set of four, so you have 2 @ 19psi and 2 @ 25psi? What happens if you switch the rear deflators around? Or if you use one deflator to do the rear driver's side then use the same one to do the rear passenger's side? | ||

Yeah, I would switch them around. On the topic of Stauns, does it take forever and a day for yours to air down as well? :-) | ||

No - I have found them to work well. | ||

I am not sure why one of your Stauns' is not delating correctly. Maybe you should ask the vendor for an exchange. Lowering the tire pressure is highly overrated in many circumstances. I see guys at the trailhead airing down well before they ever need the extra traction. With the exception of deep mud, sand, or snow, most people deflate thier tires well before the extra contact patch can be used. While traction can be gained by deflating, keep in mind that reducing pressure dramatically affetcs the lateral stability of the tire and may cause more problems than it will solve. I know this is a little off-topic, but it needs to be said. Air down only when you need it and only to the highest pressure that will get you over what you need to get over. Curtis | ||

Jamie, Pull the nipple!  Sometimes if there is not enough pressure coming out of that valve it will cause the deflator to stop early. A little lube helps with the problem too. I have gotten into the habit of pulling them every time, just to avoid them potentially getting stuck from drying out or dust. | ||

Good advice Ron, I find when I am about to enter a lonely section of beach down the slippery entry way I find that "pulling the nipple" helps get you there faster.. Cheers | ||

If the same thing happens again with the Stauns switched, then something is funky with the tires. If not, then the one Staun that stops at 20 psi is not adjusted correctly. Try cranking down the adjustment knob one full turn. | ||

Curtis - FWIW: having lost three tires in a year, arguably due to lowered pressure (although I never ran any of them lower than 20psi), I decided never to air down again. Guess what - after Rover Rendezvous, the slop in the steering box increased significantly. To the point of being similar in feel to 1/4" toe-out. Maybe it isn't prudent to air down in whale shit or something else, but running fully aired-up on washboard roads may rattle loose not only fake teeth but some other important hardware. | ||

Thanks for the input. The same thing happened with the Stauns swittched. I was wondering if it had something to do with the tires, that is why I looked at the valves to make sure they looked the same. I will try it again this week and see what happens. If something is funky with the tires, I'd much prefer to find that out in my driveway rather than off road!  I kind of thought purchasing these would be kind of a ridiculous unneccessary "extra" (low cost blingy?), but decided to give them a try. I was wrong, they are going to go to be great! When heading offroad in our state, we HAVE to air down for the mud and swampy conditions, and it is a PIA. There is always last minute prep to do - letting the tires take care of themselves is going to be a great help. They air down quickly and do not need to be monitored, just take them off when they finish. I was given a great tip for when I set them - put black permanent marker somewhere on the rear deflators. Black = Back. I would advise anyone setting them to do it in the vicinity of a REAL air compressor. I did not. I wondered how a Power Tank was able to be shipped via UPS safely? Well, guess what? They don't arrive with air in them - I found that out when setting Stauns. I'm surprised my $9 home dept plug in air compressor didn't burn itself up. That thing takes forever. I tried to get my tank filled today, called every welding shop, fire extinguisher supplier in my county. I drove to 2 of them that told me over the phone they could fill it. Then neither of them would, they had never seen one and did not believe me that CO2 goes in it -- even though I took the instructions. BTW, if anyone reading this has a power tank and uses the bracket to mount in truck, maybe you can answer another question. I soaked the boot as directed and put the tank in it. The instructions for the bracket say that if you use the boot, you must remove the bottom 2 rubber bumpers from the back of the bracket to allow room for the boot lip. The rubber bumpers appear to be welded on, how do you remove them? Thanks again, there seems to be no end for off road learning curve -- I appreciate the help. Jamie | ||

Jaime- Make sure when you are calling about getting your PowerTank filled you don't refer to it as a PowerTank, but a 5, 10, 15 Lb CO2 tank. I have had absolutely no problems having my tank filled twice at two different welding supply places because I asked about getting my "10 lb CO2" tank filled. Oh, and make sure you take the regulator off before handing your tank over. 1) This is so the guy who takes your tank back to get it filled doesn't drop your tank and screw up your expensive regulator. 2) It doesn't confuse the guys at the welding shop when they see this nice, painted CO2 tank with a different kind of regulator on it than they are used to. | ||

My bracket has a few rows of little black rubber bumpers on this inside. I just pulled off the two bumpers on the bottom row when using the boot. They just sort of pop out. Also, if you can't get a welding shop to refill the tank then try and find a place that deals in paintball supplies, they use CO2 as well in the guns I belive - but any reputable welding supply shop should do it. If all else fails, try and get a CO2 decal they use to mark the tank (they did mine that way on my first fillup) then they shouldn't give you any grief. | ||

Ditto that. As long as the regulator is off, there should be no problem, any welding supply store should be able to refill it. You will want to take the regulator off every time you refill the tank for another reason, as well. The tank needs to be completely empty before you refill it, so you will want to take the regulator off to let out any remainding CO2 before you bring it in. If you don't, the CO2 already in the tank will freeze and throw the weight off when they refill the tank. At least that's what the guy at my welding supply company told me. - Axel | ||

Peter, "Maybe it isn't prudent to air down in whale shit or something else, but running fully aired-up on washboard roads may rattle loose not only fake teeth but some other important hardware." LOL and very true. The D2 has something like 45psi reccomended for the rear tires. This is flat-out abusive offroad. Admittedly, I air down, but not beyond what I could also drive on the road with. I just see way too many folks airing down to 12-15psi before they are even on the trailhead. Further, most don't have a safe way to air back up once back on pavement. | ||

Good news! This evening I reset the rear stauns and they are working correctly. I can't switch the rear deflators around though. I'll just have to mark then so that I will know which one is for the passenger rear tire and which one is for the driver rear tire. Jay, you were right, the bumpers did just pop off! I found 2 welding supply stores that were willing to fill my tank when I called it a CO2 tank instead of a power tank (you were right!). I went to both of them today and they don't fill tanks there, they would only switch my tank for one of theirs (I declined). I finally got in touch with someone who knew what they were talking about and no one in my county "fills" tanks. Trucks bring filled tanks in and leave with the empty ones at every business. Disco owner in the county east of me has found a place willing to fill his tanks. When I find out where it is, I'll drive there to have my tank filled. I am beginning to understand the wisdom of having two tanks since it takes a long drive to fill tanks. Regarding air pressure, I have different tires than stock (mud radials) and I was instructed NEVER to deflate front tire to less than 18 and 22 on the rear tire. Thanks so much for all your help!
