We are running 8" pneumatic tires in a 6 wheel configuration and used a 1/4" center drop. We have not had much time to test with different pressures, but with all 6 wheels at ~30psi (its high, but we will be playing around with lower pressures later) we have no issues turning. There is also no issue with the robot rocking violently back and forth. You can always deflate the center or outer tires to effectively change the drop distance if you are not happy with 1/4".
