Question 5915
What can accelerate tire wear?
- Driving with the tire pressure recommended by the manufacturer.
- Driving with air pressure much lower than recommended by the manufacturer.
- Driving at a moderate speed.
Show answer and explanation
Correct answer: Driving with air pressure much lower than recommended by the manufacturer.
With very low pressure, the tire flattens, creates more friction against the ground, and heats up, so it wears faster, especially along the edges. At the manufacturer’s specified pressure and moderate speeds, it lasts longer. In the image, the front tire is underinflated.
