Here is an old thread I found on Pirate4x4 from JeepRecoveryTeam.
What’s the consensus on water in tires for crawlers??
“We've been running ballast - mostly water - in the front tires for a couple of years now. I'm pretty confident that we have enough data to figure what 'too' much is.
Keep in mind that my data is based on a linked 3000 lb rig on 37" stickies with a 5 speed dual ultimate setup. ARB's front and rear.
Bigger tires, heavier rig will make it worse. Automatics, DOT tires, and leaf springs tend to 'give' a little before the parts realize 100% of the torque.
When we ran the toy front, we ran 'bottom of the wheel' to start and never broke anything. We stepped up to 'half wheel' late in the season last year and in the women's comp we were hurrying through a course and wedged the front right under a rock at speed. I thought we broke the housing in half, but only grenaded a 30 Spliner, the only one I broke in 3 years of competing on them.
This year we switched to the Diamond 609's with Bobby's 60 CV's. We stayed at half a wheel with no problems. Around mid season we switched to 'top of the wheel' and immediately broke a front output. (Binding slightly on a down hill crackline). We chalked it up to 2 years of abuse and wheeled two more comps like that.
A couple weeks ago, we broke the front output again in similar 'lightly bound' situation. This info combined from what I've seen in the FToy comps... specifically Matt Messer's breakage of birfs and front outputs when running top of the wheel.... leads me to believe venturing past mid wheel with water is when you can expect to start seeing problems.
An ancillary side effect, the more water you put in, the faster your birfs start clicking. And of course if you run water AND have a spool or welded front, you will almost certainly break something, possibly the mythical 'driveway' break.””

yea those dudes are on another level. We saw a few of those chaps out in Sand hollow and it's a pretty much just drive where ever you want situation.
