Firestone tires bouncing

[Pete Amerson Jr]

We generally drive the the RV about 70 on the interstate.
I suppose my questions are these.
Should these tires bounce at any speed if they are balanced?
Is most likely the problem with the type of balancing used or them
being Firestone tires?
Is one type of tire balancing better suited to RV's than another?

Thanks for all of your help and comments.

The roads in West Texas are good and the Black & White's hang out in
the weeds, with radar, and backup.
