Flashcard 6 - Driving Test Flashcard Set for the CDL


The correct answer is:

All sections of the tread should be touching the road.


An underinflated tire lacks contact in the middle of the tread, causing irregular wear and heat buildup, while an overinflated tire touches in the middle but not the sides and causes irregular wear and runs the risk of bursting.
