During hot weather driving, why do experienced drivers check tires at every stop without letting air out of a hot tire?
- A.Letting air out prevents the tire from gripping
- B.Pressure rises with heat by design; bleeding a hot tire leaves it underinflated once it cools, and the stop check catches damage and heat build-up early
- C.The check is only to admire the tread
- D.Hot tires must be cooled with water at each stop
Correct answer
B. Pressure rises with heat by design; bleeding a hot tire leaves it underinflated once it cools, and the stop check catches damage and heat build-up early
Why
The specified pressures are cold pressures, and the tire is built to run hotter and higher on the road. The value of the stop check is your hand and eye finding a hot hub, a cut, or a low dual before it fails, not adjusting the gauge reading.
