I was watching truck trail last nigt and some of the trucks had water in the tires to lower the center of gravety. Does the competition guys use water in the tires to lower the center of gravety?

I heard that guy who won proto class Euro Trial this year at Norway (Per Larsson???) has his tires in half of salt water. Sure it will lower your center of cravity and probably water will keep tires better on the rims

Dude down the street from my parents uses water in his tractor tires (john deere) and he says it is loads more stable. I have wondered about using it in big meats also.

Holy unsprung weight Batman, might be a good test of CTM's and alloy shafts, fill some 44's up with chloride. I guess if you ever wanted to make your V8 run like a 4cyl.

A few years back I bought a '77 Chevy 3/4 ton beater truck, when I pulled the 9.75 16.5 tires and stock wheels off I could barely pick them up, they weight almost twice as much as my 38" Monster Mudders on 16.5x12 steel wheels, turns out they were full of cholride, no wonder the truck was such a slug, 10 ply tire on thick facotry 16.5 wheel full of cholride makes for a damn heavy combo, that's a lot of rotating mass for your drivetrain and brakes to deal with.

that's a lot of rotating mass for your drivetrain and brakes to deal with.

I suppose that water or cloride is not necessary spinning inside the tire if the speed is low enough :confused:
It shoud stay at bottom of tire and so it shouldn't stress drivetrain more than "friction" (don't know better word for that :( ) between tire and water

and the salt water does not completely corrode your rims?

Yah.. why salt water as opposed to fresh?

i know in our old ford 9n bucket loader the rear wheels are 1/2 full of some sort of liquid just for balast. you drain the water out and you cant pick up sh*t w/o that weight.

calcium chloride will completely destroy your wheels, its meant for use with tubes but once a small pinhole leak starts you might as well throw the whole wheel/tire assembly away...It will ruin both typically as the rust buildup is so great the beads are damaged upon removal.

You want more unsprung weight start strapping weights to your axles......

salt water is heavier, but it will ruin everything it contacts.

Gee lets see , water is 8.4lbs per gallon and you take 4lbs of salt and it dissolves into the water and makes it................................................ ....heavier!

You want it heavy , just use Mercury!:rolleyes: It's 112 lbs per gallon!

salt water will not freeze as easy as fresh. but a antifreeze mix is the typical for tractors around here. mike

I lost a bead once and got water inside. Reseated the tire and went on my merry way. Next season, I got new tires and when I pulled that one off, the inside of that rim was rusted all to hell. The other three were still perfect. That was fairly clear, fresh water too. I can only imagine what salt water would do... :eek:

haha i can imagine the look on the greenies' faces when everytime we blow a bead 10 gallons of mercury gets spread everywhere :rolleyes: :eek:

If Dana 60's and 40"+ swampers are not enough to bring your COG down and your still wanting more unsprung weight you've got bigger issues, maybe Rockwells will cure your urge to crush rocks out of your way rather than drive over them. Maybe I'm way off base, but I don't see this becoming the next big thing in rockcrawling.

By the way, you think water in the tire is bad for the tire and rim, try oil, a buddy filled a low tire from some hilrod's home made compressor and broke it down about a month later to find it was covered in oil on the inside, the rim was fine but the tire was about to rot through, I can't believe it didn't leak. It burned real good on the bonfire though.

Back when I was in High School I filled a kids tires half full of water in the winter.. :D the kid quit talking shit

How exaclty do you do this?

yea, our tractor's tires are filled with salt water for stability and whatnot. Why salt water? A. it doesn't freeze B. it doesn't grow algae. I don't exactly know how it's done, but I believe there's a tube bladder inside that actually holds it.

not that you would do it, but if you were to fill your tires all the way with water they wouldn't flex. Water is not compressible like air is.

Also unless you never stop or start with you truck you are going to get some interesting sloshing going on on a partially filled tire.

?? super soaker/no valve core. fire extinguisher water gun/no valve core? hose that slips over the valve with funnel attatched to fill??? come on man.. how else would you do it??

Tractor Supply store sell a tire chuck that threads onto a garden hose.

good to know... good to know...

yep, thats how. :D I just kinda swapped him watter for air :D


thump, thump, thump. hehe:p

(he was booting some 1400-24's on a cat fork lift and says "heyman whys this water burning my hands" as hes diping out the rest of the CC with a 32oz cup

what a dumb ass!(true story)

We use calcium chloride to fill all our equipment tires. We fill the tires 1/2 full... We do it to, add weight to the equipment for better COG and because it is much easier to spot small leaks before you have big leak's.

A good example is that our skid steer (bobcat ) our's is a ford .....never mind,,,,,, anyway we increase our lifting capacity by about 600 pounds, we do this by adding approximatley 350 pounds of water to our tires.

Not sure about a crawler... can't see and advantage...Now a mud monster might do well with an extra 4 to 6 pounds of water in the tires.... Momentum....

Hmmmm, interesting thought. :grinpimp:
