You find a tire with a bulge in the sidewall during a hot-weather stop. What is the correct action?
- A.Monitor it for the rest of the trip
- B.Reduce its pressure to relieve the bulge
- C.Do not continue on it; a bulge means internal cord damage and the tire can blow out without further warning, especially when hot
- D.Bulges disappear as the tire cools
Correct answer
C. Do not continue on it; a bulge means internal cord damage and the tire can blow out without further warning, especially when hot
Why
A sidewall bulge is structural failure already in progress, with only rubber holding pressure where cords have broken. Heat and highway speed complete the failure, so the tire comes out of service at that stop.
