Running water in tires?

PORTER · Jan 24, 2007

I already have stickys, so no need to make wheeling any easier. Water/shot/etc is for comps.:flipoff:

If you use shot it is alot easier calculate. I use shot in my moon buggy and it is only for comps. I had shot in my trail buggy for awhile but as soon as I quit competing with it the shot was out. On roads you had to get the right speed or it would throw you off the road

You still have to move the weight..

5 gallons of water per tire is only 166 pounds.
5 gallons of calcium chloride and water per tire is 220 lbs.
Either way it doesn't seem to be a whole lot of weight to move, Would that little amount of weight add a lot of stress to a 44 or a 60 for that matter?

If I get your drift, you will be moving the can through the water and not moving the water.

Kinda---how much resistance in there? I think you get the same result with water in the tires--it will just roll with little resistance. Now granted depending on how much water you will have inertia due to the volumn of water...

well just put water in you're tires and see. I promise it slow's a vehicle down, and wait till you try to stop, it makes thing's happen a little slower. Scientifically it shouldn't matter, but you're not allowed to have an opinion till you try:flipoff:

Yes that weight is a huge difference. That's the point of putting it in there.

I'm not arguing that point, I ran a skidder for a couple of years, and believe me, it made a huge difference. I just don't see it causing a lot more stress on axle shafts.

It increasing rotating weight being loaded on the axle bearing and ultimately the shaft/U-joint.

How can it not be more stressful on the axle shaft?

Gravity weight is 41.5-55 pounds per tire @ 5 gallons, but the resistance would be like Crash's can in the water analogy. I agree that it would cause a bit more stress on the axle shaft, I just don't see it being a huge factor in choosing whether or not to use liquid in your tires.

OK then pick up a empty tire, now pick up a water filled tire... Was it harder on your back?

How so? The weight is on the ground and stays on the ground because its fluid ..

Thats dead weight there--thats not a fair comparison. Sure water is going to make it heavier. Roll both tires and see how heavy it is--I would bet it would be but not by much.

So if my spotter is 200lbs and riding shotgun then I should upgrade to Dana 60's?

Sorry Gibby, guess you need to get on a Treadmill. :kissmyass:

crash, your right in thinking the resistance of the water flowing through the inside of the tire is low, and at a steady speed over flat ground is almost negligible.

For this discussion, the thing to remember is newton's first law, a body in motion tends to stay in motion, same thing when starting from a stop. Add 150lbs to each tire and its similar to adding 600 lbs to the car so it effects acceleration and braking. Add the other condition of lifting extra mass going up hill and over obsticles and you better know why you want water in your tires. heavy tires and axles are bad for high speeds. Imagine a rock throwing a tire up in the air and the shock and sring trying to stop it and put it back down on the ground. It becomes obvious how much harder it is to restrain a heavier mass. Keep adding mass to the tire, or unsprung weight and pretty soon the weight of the vehicle and suspension cant control it. The tires and axles start throwing the vehicle around.

It's weight being loaded on the bearing and axle because it is in the tire. It makes zero difference that it is in the bottom of the tire or below the center line of the axle.
