Why is a tire with tread separation (a section of tread lifting or missing) especially dangerous at highway speed?
- A.Separation only makes extra road noise
- B.Separation improves water drainage
- C.The separated section can tear off suddenly, destroying the tire and often causing a violent loss of control or debris strike
- D.The tire will reseal itself when hot
Correct answer
C. The separated section can tear off suddenly, destroying the tire and often causing a violent loss of control or debris strike
Why
Tread separation is the structure of the tire coming apart in layers, and speed multiplies both the heat and the tearing force. A tire showing a lifted section, a wobble, or a thumping rhythm is announcing its failure in advance.
