Correct answer
- AQue el neumático se agarre más al pavimentoTo make the tyre grip the road surface better
Explanation
The tread pattern improves grip on the road surface, especially by clearing water away when the road is wet and preventing aquaplaning. That is why its legal minimum depth is 1.6 mm. A worn tread reduces grip.
