Why do tires on cars when doing a burnout give white smoke, but a pile of tires burns black?

Just woke up to this post blown up. Thanks everyone!

You're not actually setting the tire on fire when you do a burnout. You're superheating the rubber and it's vaporizing, then condensing in the cooler air, but not combusting.

It would be more technically accurate, though less cool, to call it a steamout. ;)
