You are not actually creating 'smoke' when you are doing a burnout

By Faiming_low on 29 Apr 2016 in Discussions

Attached Image According to CarThrottle, you aren't creating 'smoke' when you are doing a burnout or a long drift. So, what are you creating then? Before we reveal what the answer is, do you know that if you do set a tyre on fire, the smoke produced is black in colour actually. So, why is the 'smoke' created white then?

That's because the friction between the spinning tyre and the tarmac superheats the rubber to as much as 400 degrees (though this does depend on the length of the burnout) which in turn melts the rubber tread, vapourising the chemicals and oil within it, sending these molecules into the air. The vapourised molecules then cool quickly and condense in the air, becoming the visible white ‘smoke’ you see. Calling it 'steam' rather than 'smoke' might be a more accurate term actually.

So now you know, the white 'smoke' is actually a by product made up billions of vapourised molecules that come from a tyre’s rubber, oil and chemical makeup.

Therefore is it harmful to breathe in

This article is poorly researched. What is produced by either combustion or pyrolysis is by definition smoke, and that's exactly what's happening here. When you heat oil, you get smoke. Note that the smoke obtained from heating oils is not a combustion product (that only happens at and beyond the flash point).

 

Steam is water vapour obtained by boiling. It doesn't refer to anything else.

 

So what you get from a tyre burnout is smoke!

If burnout is smoke from hydrocarbon, then it is as bad as smoking when we watched car drifting in exhibitions.

 

So shouldn't the organisers put out a warning for their spectators.

You have a point there. But I guess it is hard to avoid breathing in zero bad air when any form of motorsports is involved.
