L3400---proper tire pressure?

[dogdoc]

I guess I let my pressure get too low and popped a rear tire off the rim. My dad and I got the wheel/tire off and we were able to get it resealed on the rim. We aired it up and put it in a water trough and found no leak. My question is what is the proper tire pressure for the tires. I have Ag tires on the tractor. I filled them up to 30 pounds but I don't know if that is correct or not. I can't find the proper pressure on the Kubota Website. I'm thinking that tractor tires don't use as much pressure as vehicles.

thanks
