Just read about using golf balls to balance a tyre

Is this for real ? The theory sounds OK

i think i speak for the masses with

PLEASE EXPLAIN

I believe the balls are placed in the wheel (ya know.......the bit where the air goes ) and this is where centrifugal force takes over.

I understand that this is for "large" tyres (44s or so)

Just asking :wink:

never herd of that you wouldn't be going fast enough to get the forces going most of the time

On a completely different note, has anyone tried filling their tyres with water (rather then air) to lower the CoG - like they do with tractors that have to operate on steep slopes?

I imagine it wouldn't be very good/unsafe at speed with all that extra weight, but might be OK offroad???

That's teh first I've heard of it with water....

Maybe we need a test vehicle??? I reckon if you were crawling it'd work great - but when you were getting there... a bumpy it would be....

My uncle owns a farm horth of Brisbane - extremely hilly - he and everyone he knows fill their tyres with water - you end up with about 99% water in them and just a tiny bit of air to get them up to the desired pressure. If you don't fill them with water you roll on sideslopes - he has seen it happen.

What's the cubic capacity of a 44" swamper

Me thinks that'd be some mighty unsprung weight to turn

I had water in my fronts at XRCC round 0. And have done b4 on day trips, but dont go to fast as the tyres lurch every rotation of the tyre.

all the tractors dad and i have owned we have filled the tires with water,,,as said before,,its for stability,,,but we mainly did it for traction,,you really notice a difference when towing gear with the tires filled...

p.s...there was a big discusion on pirate quite a while ago about golf balls in tyres,,,,used to help balance swampers......

How would you get the golf ball through the valve stem?

whats the point in balancing a 44?

We use to always fill the tractor tyres with water!

It was quite amazing the amount of extra traction it would achieve!

I have thought of this and the only problem i can see is sometimes when driving a tractor and you either Accelerated or Braked quickly it would really lurch and jump about!

You dont need to fill them full, a touch over 1/2 is all we us to use on the tractors!

The Golf ball thing has been about for a while but why the Fark would you want to run anything bigger than a 35 on the road anyway!

P.S RUFF: I don't know thats a really good Question

u push really really hard they should go in.

is that like using lube?

yeah that might work

As the tyre turns the water does not necessarily follow the tyre. That is, it is not spinning at the same speed as the tyre.

If the water were say frozen, that would be a different story and would support your theory.

I don't see that it would exert that much more rotational force on the axles.

My ramblings........ :wink:

Ok in saying what i just said about water in the tyres, i was flicking threw Pirate when i saw "Lance" saying he was about the only guy in the Top Ten at UROC that wasn't running water in their tyres!

The water thing has it's merits...............if your rig is trailered everywhere. Offroad, lower CoG, more stable, etc, etc

I think the idea of streeting your rig with 1/2 full tyres would be interesting to say the least

Might be some "mall" factor involved though 8)

Let me ask mum.

so wat did she say tonka

i think i heard her say go t o thailand they can shoot them in!

Aparently the golf balls work sort of well (from the discussions on pirate). Not as good as proper balancing but they definately help. Although they are noisy at slow speeds.

It does look like most of the guys run the water in the front tyres for the really steep type of obstacles. Stops them falling over backwards as much. I think that the biggest downside to the water is that the extra unsprung weight will cause you to break more stuff and on wheel sized obstacles (like steps and small ledges etc) its going to be harder to control a much heaver tyre.

I didnt see or feel any problems with steering or anything else except when I got over 40k's, but I only ran 20 to 30L in each tyre.

Hmmm new 4 new long range tanks

the problem is as sam said the unsprung weight, it would kill most axles we are using. These guys are running small radial tyres on super light rigs, and it makes a lot of difference. They also have a lot of axle beef, those yanks are switched on, the toyota axles would probably hate you if you did it. they would hate you a lot! :o

The golf balls thing? man in my 42s it is recommended like 18 golf balls I just stuck in one single house brick and it seems to balance out okay. Same theory, except not as fast of a moving mass. The heavy object (house brick in my case) due to the centrifugal forces, moves to the lowest spot in the tyre, effectively balancing it out, pings at low speed, but good on road manners (handles smooth as glass)!

Once again, I have just spat coffee all over my screen due to outrageous laughter...

hey bj pop the tire off the rim id love to see how thrashed the inside or your swampers are

ROFL too funny

Noise, every time you pull up at a set of lights, you would have to yell "four"
