I have a Kubota BX-2380 and it has liquid in the rear tires. I've had a flat and now have to take it off and darn it's heavy. I had to get help putting it in the back of my pickup to take it to the tire shop. I don't know what's in the tire but will find out. Hopefully they can fix the tire, it looks to be ok but we'll just wait. I'm wondering your thoughts on liquid in tractor tires vs tire wts. The back end of this tractor is pretty light.
