I've heard about it before but untill today have never talked with someone who personally has done it.

I would think that due to the weight of the water it should stay at the bottom of the tire even while moving. It may slosh around a little bit, but for a trail-only rig your usually not going faster than 10MPH anways.

The ONLY downfall I can see with doing it is I run steel rims and even though they are painted I'm afraid of them rusting faster with water in the tires.

I've done a bit of research on it and it seems like it's a VERY common thing to be done among the rock crawler competitors. Everyone who has done it says that it has helped out a ton.

I found a 12+ page long thread on Pirate about it. Some say they are using RV antifreeze becuase it's not corrosive to the metal and won't freeze.

Gonna ask a stupid question, but can't help it...

How do you get the water back out? You would have to unmount the tire, right?

i'll ask a stupider question...

How do you get the water IN  the tire?

See I've never heard of useing water but have heard of Rock Crawlers using Sand in there tires for weight. I cann't see the water hurting, but I would put some anti-freeze in to make it less likely to freeze or rust..

Morning. Reading and learning. When I first seen the post, I throught WOW! Never have heard of such a thing, tricks of the sport or competition, that little edge. Than I throught, my lawn tractor has steel wheels and loaded tires and chains for snow blowing at home. Have had for 10yrs plus. When my son was 5 we put it in a lawn tractor pull at the flee market by us and took first place, second year 3 place. The weight in the tires really helped. Of course it has the special value stems. And the farmers around here must all have weighted tires on there tractors. I think it would work and give the person who's into competition that little edge. ---- Now for Gars throughts-- Maybe this should be in off topic. ---Or Gar where do you come from!! --- If I was going to do it or try it, I think I would put bubble soap in the water.
That way I could tell if I had a leak, rim, nail, etc by the BUBBLES which would save time looking. I would use the water at home, because its what we call in Michigan hard water, has alot of IRON in it. Which ares does. In fact I seen a blonde come into my house and take a shower and turn into a red head, married her. You can wash a white tshirt and turn it pink. We have hard water. By using my water at home I would get more weight, the iron in water, and stiffer ride and would't cost anything,its free. But at my age. I would use Soft water. I feel that I would get a softer ride and more flex. And I need both!! Thank You for putting up with me, have a great day. Coffees on here.

I would say to remove a liquid, put the valve stem at the bottom, pull the core, and stand back. For solids (bbs, powders), stem at the top and let the air out. Then remove the tire and remove any remaining weight.

Gar, i work on a farm and my boss told me that no one really uses cal. chloride or any other liquid in tires anymore. Its all cast iron weights now. I think the reason for that is the front-wheel assist. Or 4wd tractors.

We also have a tractor i like to call "tracks" - Deere 9520T :D
