Question

question 3 (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:

• Analyze each option:
• Option 1: A wear bar across tread width (when visible) means tire replacement is needed (true, as wear bars indicate tread is too low).
• Option 2: Properly - inflated tires help with vehicle control and fuel efficiency (true, under - inflated/over - inflated tires affect these, so proper inflation is critical).
• Option 3: Tire tread depth can be checked with a simple tool like a penny (not only by a trained tire expert), so this statement is false.
• Option 4: Under - inflated tires have uneven friction/heat buildup, leading to blowouts (true, as under - inflation causes improper contact with the road).

Answer:

The statement that is not true about proper tire care is: Tire tread depth can only be checked by a properly - trained tire expert. (The option with this statement)
