Outer Limits 4x4 Board

Has anyone used these or had much experiance with them. Do they hold the bead at low pressures 2-10psi? Or what is the lowest you can go with them.
Has anyone heard of any failures with them? Lick getting holes in the tube?

Try the Heep section as I think a few of them run them, I know that Jumbo does on his TJ. I know of 1 that blew the inner tube but that was because his navi over inflated it Haven`t heard of anyone having trouble with them.

Going off second hand knowledge here: I've heard 2 people bag the shit out of them (Tim Hood & Bill Larman). Apparently they are flawed because they do not have a way to centre themselves between the tyre sidewalls. They get pinched between the tyre and rim and subsequently pop. You have no way of seeing if they are in place and holding the bead on. I quote "They are expensive and don't work."

I know you want FIRST hand experience ruff, but i remember reading about Trent Leen (i think it was Trent, it was a while ago) and they said that he PUNCTURED a tyre and he kept competing.

When he finished the stage the tyre was still ok and the beads had not let go and the Inner bead lock was also undamaged!

That was a winch challenge and there wasn't much ROCK to hurt the rim, tyre or tyreloc but its still pretty impresive!

Ruff we run internal tyre locks on the Patrol we raced in the OBC. The only problem we had with themwas that we put a hole in 1 when doing a quick repair with a plug, put the spike through the tube. We ran them at 40 psi and didnt run a tyre off the rim when we dropped pressures to 8 in the tyre. A Jeep with us ran his tyres down to 4 psi on the sand wall but that was a straight 100m run with no corners.

We didn't experience any of the above problems at the OBC, and we had atleast 20 tryes off the rim (repairing punctures), you just need to be carefull.

They cost around $180 per tyre l think.

Have any of you guys using external bead locks nocked the internal bead off the rim?

nope

Nope but I have seen it happen on a US rock crawling video.

This is more of an issue with guys running 16.5 in rims cause they dont have the small safety lip that the bead must sit over, but when the guys ask about problems with loosing their inner bead with the 16.5s (on pirate BB) then the answer is very rarely.

In my eyes the main advantage of internal locks was that it protects both beads, but it doesn't sound like the inside bead is a major problem.

I dont know which ones l would buy for my car if i had to, both have advantages and disadvantage.

Tire locs are now called second airs. Roger Smith gets them made here in aust which has brought the price down heaps instead of importing them from swistizerland. I have use them and fitted them and never had a problem even with the tyres down to 0psi. I have also seen guys get flat tyres and keep on going at full thottle and the tyre stay on the rim. Saw a guy at last years OBC pop the inside bead on a mechanical bead lockwhile running really low pressures.

for my money i think they are the better choice

i think that ballsac uses them?

I have seen an inner beadlock go on a suzuki that was running about 3psi

I've not managed to pop an inner bead on my external beadlocks & overall I'm more than happy with them....
One big benefit of the internals is they are road legal......but my logic is my swampers aren't either so who cares

I can think of 5 guys in the SJC running internal bead locks and they all love 'em - but aside on onroad legality thing I see no benefit for the extra cost.....although if I was starting from scratch I might consider the internals....

A guy goes by the tag FireTruck on here has them on his Jeep. I'm not sure if he's run them offroad yet but he said they were an absolute PIG to install.

ZZZZ (Zach) and I think Cheezy knows him and may be able to offer a bit more insight than me.

Cheers.

Give my brother a call for a price on Tyre Locks. Drew 9331 6536.

I hope that was for a set of four!!

Ok i know how these things work but how does the air in the tyre get in past the tyre lock once it is inflated to 40psi? And how do you air down?



If there is anyone on here that can supply these cheaper than $180 each please PM me because there is a few of us up here in QLD that are about to buy 12 this week. Maybe a couple more if the price is right.

I was running external (mechanical) beadlocks and never had a problem with them... usually running at around 5psi.

Now running 16.5 rims and tyreloks, but haven't had a chance to give them a good thrashing offroad yet.

They are a pain to mount (IMHO). You have to take some care - mostly to avoid pinching tubes on the install. Use plenty of powder and it is much easier. I bought a couple of spare tubes too just in case...

There are 2 valves - one for the tube that goes inside the tyrelok carcase, and one that airs up and down the tyre. The one for the tyre has a big rubber flap that runs around the outside of the inner tyrelok (between the tyrelok and the tyre) and lets air in and out through there.

Oh - the other install tip was don't follow the instructions too closely when drilling the holes! For the first one I drilled the holes in-line as per the instructions and it was a DOG to install... for all the other I offset them about 2" and they were much better.

Still like birthing a cow through a pinhole though.

So the tube is replacable without having to buy a complete unit is this right?

do you have to order them by rim width/dia or will a 15" tyreloc fit an 8" and 10" wide rim.
[in case i want to use them on different rims]

They are a pain to install.

I had trouble getting the o-rings to seal where the valve on the flap fits through the rim - the normal valve position. My rims have a shallow drop and the valve hole is too close to the bottom of the drop - had to cut the bottom of the flap away to get it in.

Maybe there could be an outerlimits bulk buy or special, im keen is can get em at a good price.

correct... and it's just a tube - nothing special. Cheap to replace, and easy to carry spares.

I am pretty sure that they are for a specific rim size - otherwise the carcase won't extend all the way to the 2 tyre beads.

And yea - the o-ring thing is a pain... you have to really squeeze those suckers together to get the threads started.

I had a leak in my first one (that I drilled too close) so ended up sealing it with sikaflex.

Spoke to my brother, if you guys are seriuos we can organise a bulk purchase, the cost is as per the previous page $188 inc GST each tyre. We need proper numbers, not l think l might like some.

For the above price there will need to be atleast 5 people min.

PM me if you are serious.

Joe.

Yes they are width specific and no u cant swap them from 8'' to 9'' to 10'' as the width is the determining factor as to how they work.
RUFF think of em as just like a normal tube within the tyre therefore the air comes out of the valve like any normal tubeless and the same for the beadlock as there is two indepedent valves. 8)

P.S go through your local ARB stockist and see if u can buy in a bulk deal other wize try going straight through Roger Smith in Victoria at Beadlock Aust 03 9876 1511.

If you get a bette price from the above let me know.

Thanks. Joe.

i can get them for $180 each thats all, but i am trying to get a better deal yet. So we will see.

not really interested in doing a bulk buy though, so sorry to anyone else. Its too much hassle.

had a chat to roger smith today and the 10" wide x 15 secondairs should be available in around 2 months.
they had 7-8x15 and 7-8x16 in stock at the 4wd show for $180.
the tirelock is just a sleeve that surrounds a low profile tube with a special valve so spare tubes are available but i didn't ask price.

I went into the show and spoke to Roger about this product and i am pretty impressed. They are slightly different in designe to the Tyreloc and i beleive are a better set up. The rubber flap that you air the tyre up with is not on these they use a different designe which IMO looks like it would be a lot less hassel to work with. The valve stem for the tyre its self is also an easy swap over with no modifications.
The carcas of the inner lock is made from Polyester and has not had any failures as yet.
They can also be aird down to 0psi if wanted without risk of failure to the Second Air system.
I have a good price on these as i am perchasing 12 with some spare tubes so if anyone else is also interested i need to know by Tuesday 7am at the latest. Pm me for the price.
And just to let people know i am not perchasing them through Roger. I am perchasing them through a distributor.

Spare tubes are aprox $20 each. And the only sizes currently available are as Shane described above.
