Outer Limits 4x4 Board

Just seen an ad in the latest CCDA newsletter for a Tyre balancing compound called Magnum from Autobalance.

Anyone had any experience with this product?
What about inside tubed tyres?

(The website states it can be used in tubes.)

I Have some sitting in my laundry ready to go in my road tyres (35 BFG Muds) tomorrow after I get new valves fitted to my new rims. I'll let you know how it goes.

i remember reading somewhere thet it eats away the rubber from the inside from it rubbing against it constantly..
might be different stuff though

Im using it in my simex s with external beadlocks and it works very well. Check out the web site or contact them . The guys there are very helpfull. cheers shane........

thats when lazy americans use bb ammo or ball bearings to balance them

Check out the post found at http://www.outerlimits4x4.com/viewtopic.php?t=90013 which asks the same question.

As previously posted, there are lots of people using MAGNUM to balance their tyres. Customers have it in all sorts of tyres ranging from 265 MTRs to 38 inch TSL Swampers and all seem happy with the results. As far as the tubed tyre question goes we are still looking into this. It can be done using an special applicator, but as yet we have had very few enquiries about it and as such will look at this as the demand requires. Do you have tubed tyres? as we are finding fewer people running them these days with all the issues associated with running low pressure and tubes.

Chops has already answered this concern. There is nothing tyre damaging in MAGNUM that will effect the tyre. It is a smooth, free flowing compound that is specifically designed to be inserted into tyres allowing it to move contantly around balancing the tyre as it spins.

Jonesy thanks for the link. Bagsy thanks for your comment. Always good to get the opinions of people that have actually used a product, the link gives plenty of comment.

Just out of curiosity i popped into my local tyre shop to see what the biggest tyre they could balance was.

While they can only do up to 33's, the girl rang around their truck places and asked them..I was asking about 35 &36's onto 15"rims.

The truck place told here, No they are a pain in the ass and break our machines. lol

Funny thing is though, the manager there turned around to me and said..'theres this new tyre balancing compund out..autobalance or something..thats the stuff..best thing you can. Get that and we can putit in for you if you like.'

I am very tempted to get this to give it a go in my 33's

Autobalanceman..can i make a quick question..you sell this in a 2 pack and a 4 pack..can you do a 5 pack?

We comfortably balance upto 40" tyres on our machine and have done 44's in the past. The biggest drawback to the larger tyres is the larger weight and time required. We've used (especially on Siggi) balance patches and reduced the required weight that way.

You can buy as many as you like! 5 will cost you $130. At the moment the web page doen't give you the option to do so, but we are working on that. To get around this hit on the "CLICK TO ORDER OFF-LINE" link and we'll sort it out that way.

How does this work for non-beadlocked tyres?

blkmav wrote:How does this work for non-beadlocked tyres?

It works in the same way as it does in bead-locked tyres. MAGNUM is inserted into the tyre and the centrifigual force along with the free flowingness of the compound allow it to automatically adjust it's position, giving a smoother, balanced ride. It doesn't matter what type of rim the tyres are mounted on and will do the same thing in non-beadlocked rims. We highlight how it works with beadlocked rims to dispel the "beadlock rims can't be balanced" myth.
The main reason it is being used with non bead-locked rims is to alleviate the need for lead weights, removing the possibility of them falling off whilst 4wheeling, providing an un-balanced drive home and in turn the expence of a re-balance at the tyre shop.

Ok so what happens if you bust a bead?

If a bead was busted allowing muddy water and dirt to enter the inside of the tyre, the MAGNUM in there would end up mixing with all the foreign matter making it less affective as there would now be too much material in the tyre. If however the bead was popped and only the air escaped, it would be a simple case of just re-inflating and all would be good.
We can provide single bags of MAGNUM to your door for about the cost of a wheel balance that you be up for if a bead was popped, water and mud entered the tyre and the weights were dislodged.

I am quite tempted to try this compound. My understanding is that wheels with the compound balance well at a constant speed. How well does the stuff work when you have to accelerate and stop a lot (i.e. city driving between 20 and 80k’s)?

The freeflowingness of MAGNUM allows it to quickly adjust it's position depending on the situation. Speed, tyre pressure, load and terrain all affect the way the tyre spins. As any of these situations change the MAGNUM moves to the required position which can be noticed slightly in the steering wheel but after a few seconds the MAGNUM is back in the required position providing a wobble free ride.

How did it go with you 35BFGs????
All good???

All good now, I have 3 tyres done. The rain stopped me from getting the last tyre done.

I fitted the two front tyres to the rims with on Thursday night. Bolted them back on the Mav and went for a spin along Maroondah Hwy (2 streets away from me, 80km/h zone). All good up to about 75km/h then copped a big dose of the speed wobbles, which I have never had before with the Mav. Tried a couple of more runs with the same result, bugger. Went to bed pretty disappointed.

Drove the Mav to work the next morning, but stayed to 70km/h max (only 10min drive to work). Rang Jason at Autobalance at lunchtime, he was very helpful but surprised by my problem and suggested I try the tyre/rim combo on another vehicle to eliminate the Mav as the problem.

Rang Dad to borrow his Patrol as a test mule over the weekend. Drove home that arvo and thought I'd give Maroondah Hwy one more run to satisfy me. Took it right up to 80km/h, no death wobbles. Tried a couple more passes with the same result, surprised but happy.

After thinking about it I came up with the theory that the bags need a bit of run time to burst and disperse their contents. And because I only travelled 500 odd metres before giving them a high speed run, I ended up with a 300gram bag in the tyre rather than loose granules.

I spoke to Jason again and told him my findings and theory, which he agreed was probably the most likely cause.

Overall I am now happy with the outcome. I have a very slight steering wheel shake as I pass through 70km/h (Still smoother than previously with the standard wheel weights) but it is smooth when travelling at 70km/h.

Sorry for the long post, but I thought you would all like to know what I found.

What would be the difference to just adding 500 ml of water. Water flows very well, it would spread itself out and work the same?

Or am I wrong?

In theory, as 500ml = aprox 500grams it would be probably too much weight. But that's not the question.......
It would gradually flow around the tyre and probably do the same job after a longer period of time. Other things that have been added to tyres are sand, ball bearings ect.... but all of these substances will be damaging to the inside of the tyre. Water will also speed up the time it takes the rim to rust.
MAGNUM is specifically designed to be added to the inside if the tyre to make it run smoother and therefore is made up of substances that are smooth, free-flowing, non- tyre damaging and quick to respond to change in the tyre conditions ie speed, surface, ect.
Hope this answers your question!

I'm am going to try it I will use some corrosion inhibitor and water. Surely water will flow as quickly as beads. I'll let you know of my progress. I will start with 200ml in each tyre

The Magnum isn't beads, it is a really smooth feeling powder.

I think the big advantage of the autobalance magnum particles is that the tiny nature of the compound allows it to be dispersed around the tyre where needed but water would tend to clump together and then just drop to the bottom when the spinning stops rather than dispersing where required.
I did once drive home from Gembrook with water in my tyres after popping a bead (be it muddy water) but it was like driving with a lump in the tyre with a thump every rotation.Are looking forward to fitting the autobalance to both sets of tyres

Not exactly correct as when the wheel stops spinning, the MAGNUM will gather at the bottom of the tyre, but due to MAGNUM being a good dry balancing compound having superior flowability – this allows the balancing compound to move instantly in response to the imbalance conditions of the tyre, and to re-adjust to any changes that may occur during use.
MAGNUM is different to other products on the market - balancing is facilitated by thousands of tiny microbeads, each no larger than the tip of a ball-point pen, specially coated to reduce their friction level to a minimum. A combination of other materials covers the inside of the tyre, keeping it smooth, dry and free from static electricity that might hinder the free movement of the microbeads..
Also, the coated microbeads give MAGNUM unmatched durability, so that MAGNUM does not lose its ‘balancing power’ allowing it to be used again & again.
Hope this clears it up a bit.

Can this counterbalance mud on tyres? as like driving home from wheelin

That would surely depend on how much mud and the weight of the mud compared to the weight of the autobalance stuff.

without sounding harsh - i can't see why would it work?

all tyres are hand made and hence have heavy and light spots. now the heavy and light spots may not be associated with the thin or outer most areas of the tyre.

for eg

A DAMAGED TYRE:

like say you get a bubble in the tyre. the bubble will stick out towards the centre of the tyre thus be the last place the beads will sit as the beads ewill move to the distance furthest away from the centre.

The bubble is the lightest part of the tyre (as far as balance is concerned as the material is now closer to the centre thus reducing the "weight" acting at the specific outer radius. how does the bubble attract the beads.

A PERFECT TYRE:

a perfectly balanced tyre may not have even thickness or distance from the centre (due to different SG's of the steel belts, nylon plys, rubber and the overlaps of each) would the tyre beads not flow to the section away from the centre thus upsetting what would have been good balance?

Also

how do you reuse it? hoover it out the tyre than collect it and reuse it - you can't tip stuff out of tyres??

why not / or are they used commercially by vehicle manufactures? (understandably the aftermarket makes a quid balancing tyres)

tyre weights would cost far more to make than any beaded material. we buy beaded waxes etc for the same dollars as solid, chipped etc. most small beads are made by dropping the molten material from a chosen height into/onto various media depending on the material and the bead size. this is cheaper than stamping weights and pressing steel clips onto the lead and then balancing and installing the weights at the car factory / tyre supplier.

I am as interested as anyone in such products and would like to hear what you think. I remember callibah engineering used to sell centramatic wheel weights - I often wondered how they worked on big tyres as the weight would have to be pretty big to affect the outer edges of a 38".


Lastly just a quick plug for Ryano - Fourbys does a brilliant balance job - I've had many sets done there. The 37 beadlocked bias claws he tickled drive like street tyre smooth! I'm sure a week in the obc will change that though!
