Load control problem for axisymmetric analyis of tires

Hello,

        I am doing axisymmetric analysis of tires. First I formulated the model in displacement control method and I got the model to work and got the convergence. Then I am trying to formulate a Load control but I am not getting it to work. Now, I am really confused why this is not working. I have formulated the problem in three steps - 1. mounting, 2. Pressurizing and 3. Loading (Displacement or Load control). I have also attached the input file for the problem. It looks like I am doing it correct but I really don't know. Need help seriously. Any kind of help will be appreciated.
