Ford 4000SU with ford loader

[swattley]

my question is about the front tires and what would be a suggestion of a tire to handle the weight on the tires. they seem to be Firestone tires all around, the rear tires are loaded with water and they are about 80 percent fun of salty water, even wit the valve at 11 oclock position i got soaked replace the water air valve stem, i also wonder how much air pressure should be in the rear tires with that much water?

Same pressure whether they have fluid or
are dry. 14.9x28's? I'd run them at 16
lbs.
Ply rating is more indicative of weight
capacity than size. Guessing you have
6.50x16, or maybe 7.50x16. Run what you
have until they fail, then get the same
size (so they fit the rims you already
have, and don't rub the spindles) in 8-
ply or heavier.

4000SU should have 7.5L-15's but agree with getting the heaviest ply tire you can find.

What about the fact that the rear tires are so full of water is this normal? I thought the water was on to be half way filled

Doesn't hurt, just adds more weight, we always filled them about 80% or just to the top of the rim.
Sometimes if the tire was a little low it would squirt fluid out when you checked them with the valve at the top.

You said salty water, my money says the tires are fluided with calcium.
