Outlaw hasn't been here in a long time.
Blast from the past!
The front tire will smoke on touch down because it's spinning at a slower speed than if it were in contact with the road.
Friction and heat.
They eventually stop smoking, just like alot of tires quit smoking after so many burn outs.
The front tire begins losing speed as soon as it leaves the road. If you hold the wheelie long enough, it'll stop turning, or just barely turn from the wind.
