Because they are generating too much friction and burning.
No. Get new tires before they blow out and you get hurt.
Not on a public street or road.
yes they do
In many arenas and car shows, oil in small quantities is added to the surface of the tire to decrease traction and provide more spin and smoke. Keep in mind that if you do this for show, it will greatly diminish your ability to stop, if the car is then driven under normal conditions. Use this information at your own risk as it can cause vehicular damage and bodily harm if not done properly.
Burning rubber, or screeching the tires, and then accelerating.
It is just a form of celebration.
Could be lube/oily substance on the pads.
Friction increases temperature to near burning point.
If you mean to the tires spin at the starting line then the answer is yes. while its not enough to smoke the tires they do spin some.
Yes. If the tires were not exposed to temperatures in excess of 140 degrees, consider spraying them with toluene as a temporary repair. Otherwise, or if you don't want to die: replace the tires.
is a peeling mole a problem
that means that you have power to both tires in the back. this is really important if one tire get stuck in lets say mud and one tire isnt. both tires will spin out independently so you will get more traction and get yourself out instead of just one tire peeling out in the mud
