case 590 sl tires?

any one know if the 21L-24 tires on this hoe are calcium/liquid filled?
thinking about taking them down for new rubber but i need to know if i'll need help with them if filled due to weight
thanks in advance

Quickest way to tell is park the tractor with the valve stem at the bottom, press on the core if their is liquid it's fluid filled. If it is calcium chloride solution, wash it off right away as it is not good for the paint / finish.

thanks for the response mb but i think liquid filled tires use a two part tube with one part for water and the other for air
regardless, let me ask this another way

is it normal to have liquid filled rear tires on a backhoe of the 580-590, 310-410 size? or are they typically just filled with air?

All the tire come with air from factory, unless someone has gotten them filled at a tire shop. Typically most people just leave them air filled. Although your tire are probally not liquid filled they are still fairly heavey.

Kieth,
If they have a liquid form of calcium in them I would advise you to get rid of the calcium . If that stuff comes in contact with the interior of your rims (like from a puncture or a leaking valve stem) you will end up with badly corroded rims. It can get so severe it will cause the rims to fail. Especially at the beads. I have seen it happen more than once in agricultural tractor tires. If your tires have it them , install new tubes and do whatever you have to , to clean up the rims , then prime and then paint them.
