Authorities don't like the weld around the circumference. Just the same as it is illegal to widen rims by cutting them and welding a ring in the middle.uninformed wrote:as the title says:
what makes them illegal on road?

http://www.4wdaction.com.au/forum/sitemap/t-43.htmlAahh, a subject close to my heart.
Technically any modification to the rim after manufacture is illegal. You have to be a member of the Wheel and Tyre assosiation to repair/modify rims with approval. It's basically a closed shop (trust me, I've been down this path)
The pressure cast alloy beadlocks with a bolt on ring is not legal ( tried that one too) as the Wheel and Tyre association don't recognise the design as maintain the bead with an approved JJ standard pattern.
"ericson" style internal runflats are only deemed legal if fitted by the original VEHICLE manufacturer. (So H1 Hummer runflats can only be fitted to a H1 Hummer) I have no idea what the reasoning behind this is...they wouldn't tell me as I'm not a member...you can by the standards info, but there's no obligation to tell you what the reasoning is
Screwing the beads to the rim is not legal ( and is only a marginal fix for drag racing uses, where theres no real side load)
Kevlar rally tyres are for rally cars...they dont last long are not designed to work at low presures. Those that do ( Stonewalls, baja FC's, Baja pro's) are not legal on the road , not speed or load rated and are actually stamped to reflect this. Offroad racers don't air down to 3 PSi and go crawling.
With the weld in beadlocks the inner ring needs to be welded in straight and without any pin holes in the weld. The inner ring is effectively laminating or strengthening the rim - anything you do to bend it would have rooted the original rim anyway. In all the years we've sold weld in kits, I've only seen a couple of the outer rings bent beyond repair, again the rim was rooted anyway. Using high tensile bolts ( we use HT cap heads and nylocks) and 24 bolts per wheel stops the breakage issue and any leaks between the bolts.
It's not uncommon to sikaflex or silastic the tyre to the rim on both sides ( your friendly tyre guy wont be so friendly anymore)
Internals are a good thing- minimal mods to the wheel, seals both sides and will recover from really big hits. There harder to fit on smaller tyres, but once fitted they're pretty well maintanence free. They'll actually make it EASIER to swap a tyre in the field than a normal tubeless setup. the beadlock makes it easy to set the the bead.
As far as balance goes, it's a big call- the tyres will need to be able to be balanced, the rims straight and true, the beadlock fitted properly and all assembled well. If you start with the thinest, nastiest malaysian rims you can get for $48 each, do everyone a favour and put them on a balancer without beadlocks or tyres- you'll be less likely to scream blue murder when those beadlocked bias ply swampers wont balance.
If you get an approved rim repairer to drill the hole, the rim is legal.
According to the Staun Internal Beadlock Disclaimer they are for "Off Highway Use Only!"

Not according to the quote above from Ryano. AFAIK, rim repairs and modifications are also legal if they conform to the standards AND are done by someone authorised by the tyre and rim association.nastytroll wrote:modified rims are illegal, hense internal beadlocks are technically illeagal if you have to drill the second valve stem hole.
Apparently there is a company selling rims with 2 valve stem holes now though.
They are illegal as they are not a recognised/approved design. EVEN INTERNAL beadlocks say "offroad use only" or similar on them!!! So they aren't legal either!skip-unstuck wrote:Because they are welded to the rim, I beleive you are only allowed one weld per rim,
Hence if the locking rim is cast into the rim and the one weld is only on the centre they would be technically legal, ie, Walker Evans rims.
Did you read what Ryano wrote:Chucky wrote:Surely a rim manufacturer reading this forum can see a need for a rim with two valve stem holes.
However I can see the extra hole would easily double the price of the rim
But that is all academic since the internal beadlocks are illegal...If you get an approved rim repairer to drill the hole, the rim is legal.
But how do the authorities prove they WEREN'T done by an approved repairer/modifier???nastytroll wrote:I'm not dissagreeing with the quote from ryan, but how do you proove to an authority that the holes have been drilled by and aprooved wheel repairer?
Carrying a stat dec from someone to say they did the mod would not be enough, I would say you would need to have a serial number on the rims?
Any one got a link to core ?bru21 wrote:the general problem is that the code does not allow for circumferential welding. This was to stop people adding width to rims by adding a strip of flat steel in the VW days - rim balance and weld failure were the problems. Split rims are very similar to locks and are legal.
as with anything - go through the correct channels and it will be sweet.
C.O.R.E. will get each rim crack tested x rayed and certified for road use for about $200 each from memory. They are stamped as meeting ADR's.
core rims are not typical beadlocks and have a locating lip made out of the parted off rim lip.

I've since had a chat to Staun about this. The disclaimer is for the US market only (Don't know why they didn't mention that in the disclaimerISUZUROVER wrote:Ryano wrote: If you get an approved rim repairer to drill the hole, the rim is legal.

).Staun have approached Performance wheels to have a selection of their range to suit internals. It's all going ahead and available now. This will mean that the rim is a factory manufactured and tested rim that will have the second valve hole in it for the internals. So there will be off the shelf options for internal beadlocks to be legal.ISUZUROVER wrote:nastytroll wrote: Apparently there is a company selling rims with 2 valve stem holes now though.

Apparently they are 100% legal and approved for use on Australian roads.

I know this was directed at ryano but I don't know of anyone either.ISUZUROVER wrote:

This really seems like the best system to me.
WHY??? Early land rovers had a 2-piece bolt together rim. If they are made without any circumferential welds then I can't see what would be wrong with them?Gwagensteve wrote:but just as illegal.

Ben, i was actually going to ask if a person used these rimes and welded on a bead lock ring them rim would only have 1 continuious weld.... if done correctly they could be argued as legal????

They would only be illegal if they were manufactured yourself regardess of how many welds they didn't have, and any newly manufactured rims still have to go through testing if they aren't approved elsewhere.ISUZUROVER wrote:WHY???

OK so a factory 2-piece bolted rim (e.g. land rover or hummer) with an internal double beadlock would likely be legal. As would the Hutchinson rims you mention.Gwagensteve wrote:They would only be illegal if they were manufactured yourself regardess of how many welds they didn't have, and any newly manufactured rims still have to go through testing if they aren't approved elsewhere.ISUZUROVER wrote:WHY???

It appears that any wheels sold in australia for road use require DOT approval or equivalent. Hutchinson will sell a double beadlock ( hummer/statzworx) style double beadlock that is DOT approved and therefore should also be legal in Australia, and the fact I have seen a Chrysler demo JK wrangler in australia with MOPAR performance beadlock rims (hutchinson) would indicate it is at least feasible - the hutchinson rims would have to meet the same standards as the stock rims.
There aren't any current DOT approved single bolted beadlock rims. One possible issue for the DOT approval process is that single mechanical beadlock rims actually seal and clamp the tyre on the inside surface of the tyre bead seat area, an area that isn't designed for load and isn't designed as a sealing sufrace. Despite several rim makers in the US trying for DOT approval for single beadlocks, I've never seen one achieve it, including for rims with no circ welds. a cast/forged rim with a single circ weld holding the beadlock flange on is not, in itself, a reason for illegality, but the design and construction of the rim would still require approval and testing.
Also, as far as I am aware, the welds connecting the centre to the rim are not considered as part of the one permissable circumferential weld.
A 2 piece double beadlock ( hummer style) still seals the tyre and retains the bead exactly as the tyre maker intended, but a rim made this way would still have to go through DOT approval, which apart from design verification etc would require explosive blowout testing etc.
As an aside, it's a shame that DOT approval seems to apply for rims sold new in australia but not tyres.... or swampers would be road legal in australia.
AFAIK, there is no requirement for manufacturers to go though the ADR approval process for rims if they are DOT approved for the US market, as an example. I'd also guess the Australian standards are almost exactly the same as DOT for rim approval.
