Firestone tires bouncing

[Pete Masterson]

I'm not sure if 78 mph is legal in any state -- and most heavy duty
tires are rated to 70 or 75 mph maximum anyway.

The "dust type material" used to balance tires is very sensitive to
excess moisture -- it will clump if there's too much moisture in the
tire (and the moisture comes in with the compressed air).
