mot large aircraft have some type of spin up system, as does the one in that picture. It is not an exact match airspeed to ground speed, so you still smoke. That looks like pretty excessive smoke, the photographer may have caught a lower time pilot flat spotting the tires by having some brake applied at touch down, that happens all the time.
I've worked on these for 35 years - there is no "spin up system". The tires are not rotating until they are forced to do so at touchdown. Probably a dragging brake.
