Anyone seen or used these? Good, bad, ugly?

he has.

OK, here is the link to the review.

That's OK. I understand what they do. He sells them..... I want to hear from people who have used them hard.

- Any problems with leaks?
- Do they balance OK?

I see Ruff has some. Any problems?

[red90]

Hmmm, are they actually rebranded Tirelocs???

Tireloc lists them a distributors.....

[ausyota]

In that review it states that with the locks in you air down quicker.
But I think Ruff runs these and said they made airing down slower as the bag restricts the air flow coming out (dont quote me on that just thought I read it on here somewhere).

I've got no experience with the SecondAir ones but I do run a set of the TyreLock internal beadlocks which are basically the same premise.

Compared with the challenge of balancing a st of 38" Boggers there's no issues with balancing and you've also got the benfit of them being street legal (if you are running rated tyres that is).

My only real issue has been that I've found I need to run them with heaps more pressure than was originally recommended. I think the instructions say 25lb but I've found that if you are driving hard then stuff can still get wedged down the bead at that pressure so I've run mine at about 40lb and had no real problems since then.

Can and / or do the pop or leak? Yes - I have seen it happen but only under competition circumstances and it was only a matter of replacing or patching the rubber tube that sits inside the kevlar casing. That said, I've given mine heaps of punishment and never had a problem . . . and how many guys do you see out there beating the bejesus out of their steel beadlock rims trying to get them to reseal after they've given some rocks a big nudge?

We had two cars using them on a club trip on sunday - 1 Vitara and 1 Hummer...

The hummer had a bead leak on one of its tyres. But i don't think it was enough to cause any real problems (since tyre pressure could be controlled from inside the cab ).

We ran them in the outback challenge last year, they worked fine however we did destroy 2 inner tubes, also you need to be carefull if using a tyre repair kit as you can puncture them with the spike.

They can blow a tube every now and then, but they are all available as spare parts.

I'd fit secondairs without a question, the difference they make and the little impact they have on day to day driving makes them the perfect product.

[Area54]

What is the method for repairing an inner tube in the secondair?

On the track and roadbikes (bicycles) of the old skool set, the guys ran a tyre/tube assembly called a single. This was a tyre with a fully circular case that was stitched together along a seam on the inside of the tyre. Do the secondairs have a similar setup...might be time to buy the wife that new Janome...

i fitted the 15x10s and found that unless they're at around 40psi they wont work

We also found that running them at 40 psi gave the best results.

The Secondair Air instructions state "Inflate the Secondair to 2PSI Higher than normal Road pressure"

[bj on roids]

I run 35psi on the street.

So 37psi is gunna be about right!

so are you saying that when aired down for trail use they suck ass ??... & that they would work better with 40psi offroad ??

Why would you air them down for trail or any sort of use, this would be of no advantage.

[srowlandson]

Secondair has about 35-40 psi ALL THE TIME....


The Normal Value to the tyre, you can vary from 0 - what ever you run on the road ...

i think i was getting confused there for a second

[DiscoDino]

I thought since I am in Germany, I´d call up the dealer and get me a set for my 15x10 and 36"-38" SX...

THEY QUOTED ME A WHOPPING 750€...EUROS...That´s 1,222.24 Australian dollars...

Now I really do not care how they perform...but I´m willing to reseat a tire for the rest of my life and not pay that much for them!

[red90]

So buy them direct from the link at the top. $180 x 4 = $720 for a set. ABout the same price as a set of steel beedlock rims.

Does anyone know if these are rebranded Tirelocs or do they make their own/

[Bodge]

We ran them in our last challenge for the first time and they didn't fail at any stage.. The only PIA is the airing up and down. When the second air is at 40lb air is reluctant to come out the outer valve. so you have to do it in the right order... When you head back out on the road you have to let down the second air to 3 PSI or less and then pump your tyre up to street pressure - time consuming but worth it...

Here is a tip - we usually run our tyres at 8lbs so we would let them down to that then pump up the second air to 40lbs which would raise the overall tyre pressure to 10-12lbs. Then you can't get any further air to come out of the outer tyre! To get the right pressure we had to let the outers down to about 6lbs first....

Tip = Do all this experimenting before you get to the start line

[red90]

Hmmm, that's no good. The litlle bypass dohicky shold let the outers fill no matter what. They must not quite have the design right.

Do you have the dohickys in there correctly.

[Drafty]

Are you sure they are fitted correctly. We dont have these problems, what about other people.

[Area54]

Nobody has answered the question as to how to repair the inner tube if punctured or pinched during assembly or trail use.

You take the tube out and put a patch on it as you would a normal tube.

[Area54]

The tube is encased in a fabric outer, how is the tube removed from the fabric outer and then reinserted after repair?

[red90]

It isn't fully encased in the fabric, just the outside and sides. Rim/wheel side is open.

[Area54]

Ah...

As mentioned in an earlier post, I have the Tyrelock ones which I believe are essientally the same thing. I have never had any problems getting the tyres to reinflate or deflate. It took a bit of experimenting to work out what others seem to have settled on as well - that 40psi works reasonably well.

I had no idea what I was doing when I installed them but followed the instructions and had no dramas. It was no more fiddly to install or remove a tyre than with a mechanical beadlock and as one of the others have said, if you can use tyre pliers, glue and patches, fixing the inner tubes is a no brainer.
