You are right Paul, When the tire is dynamic or hooked up it is transferring torque it is flat on the bottom and not round, and operating in an in balanced condition smoothly. The minute that it spins free and goes round the imbalance will be magnified. If he could spin during the run he would know it like you would suspect. But if he removed the shocks and had a balanced set of slicks they will spin smooth. The bad shock or wasted spring will just allow it to be detected sooner like you suspected and bounce without control from the shock.
