Staun Internal BeadLocks

[mrblaine]

We spent Saturday, about 5 hours of it installing a set of these in Brian's 16" rims.

I had been warned that they were "fiddly" to install and therefore Time consuming, problematic, and generally the reason they were shunned in their native country.

Well, I guess that I've spent enough time playing with fiddly stuff that these just weren't a problem, as we installed 5 and a half of them in 5 and a half hours and that includes busting the tires down by hand and yanking them off the rig.

A few things that helped, Harry brought his TyrePlier tire irons with him and after using them, I convinced him that I needed them more than he did. Literally, you can bust down a tire and have it off the rim in about 10 minutes or less.

I did rig up a very simple little sling to hold the tire up that was adjustable and although crude, was very effective in providing the needed clearance to get everything placed correctly inside the tire on the rim.

The only downside to Brian's install is the placement of his stock valve stems and their likelyhood to get ripped off on the rocks. As luck would have it, I was given an external valve stem installer that I tested and it works flawlessly. I can pop in a new valve stem without breaking down the tire in less than 1 second after the gun is loaded.

We also are testing these with a regular beadlocks, my two rears to be specific in an attempt to stop burping air. Anyone that was on the OL run knows how problematical that became after awhile.

Lest I forget, the time also includes drilling for the second valvestem. All in all, I'd install another set, no problem.

Look for some test results in the very near future.

It is kinda cool to have double internal beadlocks and very factory appearing rims at the same time.

I've been using these for years. Nothing easier on I've ever found for tire swapping duty

post up some pics of the product.

blaine, you were losing air on the inside bead with your beadlocks?

[blkTJ]

I look forward to testing these things out. Thanks for the opportunity.

Not only losing air, but rolling the inside bead off when it was being used as an anchor point.

No pics yet, Harry (Staun Rep) has them all.

(congrats on your new beadlocks Brian!)

Are these the ones that were developed by the Swedish Army?

No, but very similar and are made in Australia. Currently marketed down there under the name SecondAire, but will be changed to the Staun Internal BeadLock for the stateside sales.

[Anders Karlsson]

Do they look like these? http://www.tyron.com/beadlock/bmainframe.htm

I wonder what happened to the Swedish company Tireloc, they used to have a website but it's not there anymore. They had a product that was like an inner tube made of Kevlar, they looked like this

They look very similar to the Tirelocs. Instead of Kevlar, they use a quality polyester webbing with nylon sidewalls in what looks to be about 500 denier weight yarn.

All this talk of removing tyres has me wondering -- Do you have vehicles with split rims in the US? I mean SUVs not tractors etc. People who do a lot of outback driving love them as it makes tyre repairs very quick and easy, just deflate the tube (if it isn't already), break the bead, remove the ring and slide the tyre striaght off the wheel.

After removing the the wheel from his vehicle, a friend of mine can have the tyre off his rim in under 2 minutes if he makes a race of it.

I know we have split rims. Hummers have two piece rims with an o-ring between the halves.

There are also some for civilian use I have seen a pic of floating around.

That 2 minutes is pretty fast. I can't even find the tyrepliers in that amount of time.

Split rims used to be popular (still might be to some extent) on semi-trucks years ago. Don't care for them myself. I've seen a few where the ring wasn't seated properly and let go when airing up. Since most folks lean over a tire when airing up, you can imagine what happens when the ring lets go. Not nice.

Then again, it does make swapping tires quick!

To do that time he has the tools prepared, by his side.
There was a split-rim tyre changing competioin at one of our local 4x4 shows. Dave beat everybody else by minutes.

[Scott Hill]

Plus C-dot has made split rims illegal. that is why the _-net rumor of bead locks are illegal.

[blkTJ]

hopefully this will be a useful item for folks who have mounted the second valve stem inside the rim and happen to have big drum brakes...



(made for BMW motorcycles BTW)

[Paradiddle]

Brian - where did you get those? How much? Bring me 4 please.

[blkTJ]

They are here

but you only want one. they are meant for checking pressure and filling only, not for leaving on.

order your own.

[LeadFoot]

Without reading into too many links, isn't it those bags that go inside the tire and aired up to around 20-25psi? A friend has them on her CJ with 36x13.50 irok's. They work awesome! Still allow the tire to flex good too. If you look closely, you can see both valve stems.


This is their latest Paragon pics, the rest are here.

Oh - I thought those were angeled valve stems (permanent).

I have the angeled screw on ones - got them at the RV store for $3.00

do they swivel, meaning do you just turn the cap, or do you turn the whole thing on??? I won't have room to turn the entire stem.

[Scott Hill]

I would like to try a set but are they really 200 (aprox bucks) each??

if that is the case what do Champions bead lock runs??

Comparatively, about 62.5 percent of the Stauns.

They swivel - they work the same except mine are chromed.

RV stores carry them in different lengths and with different bends as well.

I'd like to know how well these will balance compared to conventional beadlocks.

for the record... they balanced great. I did have some fun explaining the second valve stem to the guys at America's Tire though.

A friend of mine has these on his jeep.
38.5x14.5x16.5 SX's
They are the secondair brand I believe.

Has had no end of troubles.
They will not hold air for long at all as mud and things get into the bead when aired down.

Then the other day they were all flat and each of them had blown or split somewhere.
Not sure how this happened, but it sure did suck right before a big jeep trip.
Maybe was to do with running them under 10 psi for a half an hour on the bitumen but we were taking it slooooow

Would possibly be fine in the desert though

So the jury is out for us.
Mechanicals just seem to work.

Seems sort of like and ARB v's Detroit thing
Did I just say that....

Sounds to me like some installation issues. Having played with them, if they are installed correctly, it'd would be pretty hard to get mud in the bead.

As a way of ascertaining that, we actually used the Staun Internal BeadLock to seat the two outer beads at the same time.

If they do that with no air, how is it that mud will get in there? That seems to be the purpose of the lock. To force the two beads against the rim.

I will venture a guess that maybe the wrong size or a tweener size was used. I ran into that trying to fit a set of 17" rims. They skipped the size I needed.

I will agree that the mechanicals work perfectly on the one side. My problem was I kept losing the inner bead or continually burping air out. What then?
