With the camera mounted on the wheelie bar you loose all frame of reference. It's not bouncing the tire, it's the camera moving.
After spending MANY MANY hours recording and looking at launch videos, I would recommend you focus on getting shots from the side of the car. I've found that to be much more useful.
If you're using a gopro, their software is really good for reviewing in slow motion. You can zoom up to watch tire hit too.
Check this out. I just threw this together for someone to show what you can do. This was one run, one camera, just edited 3 ways.
