Why does the Delorean have flame trails when it hits 88 mph?

As I understand it, the sonic-boom type effect is the temporal barrier being broken, but what about the flame trails?

Relevant points to consider when answering:

* The flame trails exist **after** the DeLorean has disappeared through time, not before.

* The flame trails even occur when flying through the air.

* The flame trails persist on the ground, i.e. something has literally set the asphalt on fire (or something flammable has been spread across the ground). The trails also seem to have at least some persistence in the air, i.e. they don't immediately waft away like most gases would.
