L4400 4x4 New Tires W Water

[Gord Baker]

I took my Kubota in for new shoes after 12 years. My tire dealer died of C-19 his son took over. This tractor always rode great, it now rides like it has square wheels.
Son replaced the 4 ply with 6 ply, just for info.
The new industrial tires are water filled, not 2/3 or 3/4, 100% filled. Rolled to the top, the valves squirt water. That seems odd.
The Rears are at 32 pounds, I mostly mow and pick up limbs, trees, etc.

The fronts are at 45 pounds
I get it that the fronts with a grapple and root rake need to be at a higher air pressure due to the FEL weight plus loads.

Seems like my prior wheels were about 2/3 full of water and the rear tires were at about 20 pounds air pressure.

If I remember the original info, 12 years ago, you must have space with a water fill to allow the tire to still flex, otherwise it rides like the tires are all solid.

I doubt your tires are 100% filled. If they are, roll valve stem to top and loosen til air begins to come out. I believe that tire pressure is too high but try it lower unless you do a lot of paved road driving.

Number one - with the tire air valve to the top, filling with the liquid is supposed to be stopped when the fluid spits out when releasing the pressure buildup during the fill process - my guess is that the fill was continued after this point and stopped when pump could not overcome the pressure build-up. IF it is just water, then (with the weight off the wheels), rotate a valve to the top and remove the core, when the fluid stops spurting out, top up the pressure to 20 PSI (or to specs). Presto - all taken care of
