Touchdown of an airliner almost always results in a big cloud of smoke as the rubber burns off the tires when they spin up to speed after first contacting the runway.  Lots of tires can mean even more smoke and the 20 main tires on an A380 should mean a lot of smoke.  Less often noticed is that the same thing happens when the nose gear touches down.  As I shot this A380 landing at LAX, I happened to catch the smoke from the nose gear as it hit the ground.
