SUBJECT 4 · EMERGENCY AVOIDANCE

Tire pressure that is too high or too low can easily cause a blowout.

A
True
B
False
ANSWER · A
Both high and low tire pressure can easily cause blowouts. Too-high pressure reduces the contact area between tire and ground, dramatically increasing pressure and wear per unit area, which can cause brake failure. Too-low pressure increases the contact area, abnormally raises the temperature inside the tire while driving, and severe sidewall deformation accelerates the aging of the internal steel wires and ply layers, creating blowout risks, increasing fuel consumption, and shortening tire life.
