Outer Limits 4x4 Board

Hi all, I've seen this set up at the dragstrip before, basically big self tapping screws through the rim (alloy and steel) into the bead...



Has anyone tried bead locking their tyres this way? I know it's a 'cheap' way of doing it but seems to achieve the same thing, in a way. I haven't seen any other 4WDers do this off road. I'm thinking of doing it to my set of play rims/tyres so I can let them right down. I've read in other threads that the weld on bead lock systems are no good to drive over 60 KMH and don't balance real well and as I often travel on the highway to get to where I play, this could be a problem.

Your thoughts please, pros/cons. Be honest!!!

Would think the screw's would tear out on Lateral Force

mud and water will rust the bead

Drag cars are trying to stop the tyre spinning on the rim , four wheel driving need to stop the tyre pushing off the bead . different type of load I would think it will just rip the screws out after a while and stuff the bead wire bands.

Just buy some weld on kits you strengthen the rim no mud in the bead and stop fearing driving on them.

Doesn´t work at offroad use.
For good balance and lighter weight use Staun inner beadlocks, not the cheapest way, ehh...

Larie sternbek (sp) had done this to his hilux in the earlly days from memory he used sigafex and roofing screwes, but like i said this was in the earlly days. I even think when 4x4 montly did a feture on his truck thay said something about it.

U.S wheelers have been using these for long time, the screw barely goes through the bead, the screw then holds the tyre bead against the rims outer edge.

This mob sells screws for beadlocks
http://www.inchwormgear.com

Mock (LJEXTREEM) tried it on a Zook, from memory it kind of worked but stuffed a good set of rims and can damage the tyre.

Maybe just run some tubes or save some pennies and buy some beadlocks.

I wouldn't advise beadlocks down the highway either.

Some alloys with inchworms

Yeah i saw Laurie's come off in a winch challenge years ago and it kind of wrecked the tyre when it broke the bead.

Are beadlocks really required? I have done a fair few things in my old MQ and never had either internal or external beadlocks. I did have problems with mud getting in the beads so i bought standard tubes and problem solved!

Why are the hummer style beadlocks not replicated aftermarket ?

I would have thaught the dual bead lock design of the hummer split wheel would be far superior to a single bead lock?

They are. You can buy DOT approved wheels with this style from the USA, just $$$.

I probably saved some info and will edit this post if I find it.

Edit: Here is one manufacturer http://www.high-impact.net/wheels/dot_a ... dlocks.htm

However, DOT approval in the US does not, automatically, mean ADR approval here, or Swampers would be road legal in Australia.

I have no idea what was required to certify the Hummer double beadlocks sold on new hummers here in 1996.

Likewise I've seen Mopar/Hutchinson double beadlocks here on JK's but have no idea if they are actually ADR approved.

Bead screws can (and do) work. VPW sell Moroso bead screws. they are hardened, and use a coarser thread than common self tapping screws.

It's quite time consuming to fit them (properly) as you need to start with a bare rim and drill it, then mount the tyre, seat it, then install the screws. Of course, enough screws will prevent the tyre EVER coming off, but there's no guarantee you won't still have bead leaks and obviously the tyre and wheel are damaged. If you're not worried about trashing a set of wheels and tyres, it's an option, but really, weld on beadlock kits are $100 a wheel now.

I have no idea why you wouldn't run beadlocks on the road. (obviously they're not road legal.... but is everything on your car?) but if they are mounted properly they run true and you'd never know they are there.

I've been running mechanical beadlocks on steel rims for 10 years. they rock.
