Tire pyrolysis no doubt produces char (aka Carbon Black), oil (pyro oil) and gas (pyro gas), but what's the actual products produced during pyrolysis?
Is it char, oil and gas?
or
Char and gas, where the gas then condenses into oil?
When you pyrolyze tires, you will get three products:
1) Gases that contain CH4, H2, CO, CO2, H2S, SO2, and other hydrocarbons. This gaseous mixture could be used for heating purpose and, hence, is a gorgeous fuel product..
2) Char. This could be another solid product.
3) Tar oil which is a liquid product that could be used as a fuel, in pharmaceuticals, etc.
If all depends on the objects of this pyrolysis.
Hope this helps answer your question.

In addition to other answers you get a lot of carbon soot and black smoke.
According to Martinez and his colleagues, they stated
"In a strict sense, the pyrolysis process produces two different
fractions: a carbonaceous solid known as char and hydrocarbon
vapors known as volatiles (which involve condensable and
non-condensable gases).".
