Question

question 15 (multiple choice worth 3 points) (lesson 8.3 lc) which of the following statements is not true about proper tire care? if you see a wear bar across the width of the tread while facing it, it’s time to replace the tire. properly - inflated tires are critical to vehicle control and good gas mileage. tire tread depth can only be checked by a properly - trained tire expert. under - inflated tires experience uneven friction and heat buildup, which can lead to blowouts.

Explanation:

• For the first option: Wear bars indicate when a tire's tread is too worn, so replacing is correct.
• Second option: Proper inflation affects vehicle control (e.g., handling) and gas mileage (less rolling resistance), so this is true.
• Third option: Tire tread depth can be checked by non - experts using simple tools like a penny (inserting it into the tread; if the top of Lincoln's head is visible, tread is too low), so this statement is false.
• Fourth option: Under - inflated tires have more contact with the road, leading to uneven friction, heat, and potential blowouts, so this is true.

Answer:

C. Tire tread depth can only be checked by a properly - trained tire expert.
