Outer Limits 4x4 Board

I can doubt very much you will hear them antt. Anything will work.

I use conventional house bricks in my 42s, more of a dull thud as they hit the ground..


No, but seriously, the golf balls.... ball bearins etc work well!!

how many golf balls are needed? Is it only a couple and why does it work as the out of round area obviously moves aound the tyre yet the golf balls would be at the bottom?

I don't think the ball bearings will work.

I have a theory that the items that you put in the tyre have to have a volume that exceeds the density by a certain factor to be effective. Golf balls, not being dense yet have a reasonable mass and volume, seem to be the go, also the equal powder that is mentioned elsewhere seems to have similar properties.

I think it might be time for a serious scientific experiment, I'm going to buy some rims (second hand) for some tyres I have here and will do this experiment...now where are my goggles, I hope the water trap down at the golf club isn't too murky...

Centrifugal force, this is where I think the theory of mass/density/volume comes into play. There must be a fine line between the items rotating with the assembly in the heavily weighted side and them finding their place on the off weighted side. At highway speeds, the average tyre is doing around 600 RPM (2500 motor revs, 4.1 diff gears), so the golf balls prolly won't stay at the bottom, they will fall into line with the out of balance section of the assembly.

OK - here is the precise method I used to calculate the exact number of golf balls required per corner...

I searched on Pirates. Found a few people who used 4 golf balls for 36's, and a few that used 8 golf balls for 40/42's. Since I was running 38.5's, I took the average balls per inch and multiplied by 38.5. In other words I just went half way.

Oh, and the equal stuff works well, but because it is a powder is not really suitable for 4x4's... if you air up and down alot you lose powder and the moisture you continually pump in clumps the powder and makes it stick to the inner walls of the tyre.

Have also seem people using stainless steel ball bearings.

Oh, and there is a product available (which I can't for the life of remember the name) which they use alot on trucks. It is a disk that has an outer (sealed) chanel which contains lead weights and oil. Might be centramatics or something. THey are drilled to your bolt pattern, so you just bolt them on between your wheels and mounting surface. Same deal - centrifugal force distributes the weights where they are needed.

Damn'd if I wasn't right...

that is incorrect.....this is from their website...

" The Equal granules will never reach the valve core because of the fitment of the AirX Filtered Valve Core that comes with every bag of Equal. The AirX Filtered Valve Core is part of every proper Equal installation, no matter who tells you otherwise. If you purchased the Equal granules but were not provided AirX Filtered Valve Cores, you were not dealing with an authorized or trustworthy Equal stockist.

However, installing Equal in your tires will increase the time it takes you air down. The Equal granules will attach to the screen mesh in the AirX Filtered Valve Cores and will restrict the flow of air through your valve stems. Unless you first push air through the valves before airing down in order to push away the Equal granules from the protective screen, you will find your airdown time will increase due to the restricted airflow. This restricted flow is easy to eliminate by injecting some air into the tires to clean the screen mesh on the AirX Filtered Valve Cores prior to airing down. If you do not flush your tires' valves prior to airing down, then air will merely trickle out of the valve stems because of the restricted airflow. "

nice one, I stand corrected... my info was from folks who have used it before... I guess they didn't go through "authorized or trustworthy" suppliers.

And who would have ever thought that there was anyone out there willing to rip us off so blatently...

I have Equal in stock if anyone wants to give it a go

yes, but does it come with the new valve

wow golf ball inside tyres I never would have though.....

might try it someday....

I have heard good reports from users of equal, but it has a problem with getting wet/moist. Okay on a truck that spends it's life on the road, but with constant deflation/inflation cycles, there may be a chance to infuse moisture into the case due to saturated air.

Beltek is another balancing product, it's a liquid though. Looks a lot like bear spooge, and semi sets in the case, but will remain gel/liquid to retain the balance, and will move around. Like most internal balancing products the wheels need to be stored properly, flat in a stack not standing up.

Ofcourse have the proper valves and applicating stuff.
