At a carpool spot near Naarden you feel a slight vibration in the steering and notice the left front tyre is worn at an angle. What is the most likely defect here?
- A nitrogen tyre losing pressure, recognisable by the green valve cap
- ✓ Suspension — tracking is disturbed, for example after hitting a kerb
- Just low tyre pressure, nothing else going on
Correct answer: Suspension — tracking is disturbed, for example after hitting a kerb
Explanation
Steering vibration + uneven wear is attributed by the book to the suspension (tracking), not primarily to pressure
Why learners get this wrong
- Wrong — the green cap only says something about the filling (nitrogen), not about this wear pattern. Vibration + uneven wear = suspension
- Steering vibration + uneven wear is attributed by the book to the suspension (tracking), not primarily to pressure
