Why does my club bounce off the car tyre when I hit it?

What do I need to do differently?

Your club should bounce during the Tire Drill, but only once. If, after the first rebound, your club strikes the Tire a second time, then you're using Hand (or arm) Forces. Those forces can't dissipate as fast as the club can return to the Tire.

In a typical Swing, no hand forces are used to strike the ball nor are arm forces used during any part of the Downstroke. Only Pivot.

The Pivot does the work, the hands guide.
