The F-101B had enough engine power that if you held the brakes and ran
up and plugged the burners in it rotated the tires on the rim(s) and
blew them.You could see smoke as they skidded down the R/W.

Hardly relevant to the question of what happens at the *very start* of a
takeoff roll of a transport category airplane. Even in the case of the much
higher power-to-weight ratio of the F-101B (or other fighters, for that
matter), the smoke doesn't occur immediately upon power-up.
