During a pre-drive tire inspection, besides confirming proper inflation, which of the following should you check?

• A. The direction in which your tires are pointed
• B. The tread depth of the tires
• C. To ensure all tire stem covers are firmly attached
• D. The condition of the wheel lug nuts

Answer: (C)

During a pre-drive tire check, you want to protect the tire’s inflation system as you verify pressure. The tire valve stem cap plays a key role in that protection. It seals the valve stem to keep dirt, moisture, and corrosion out, which helps prevent slow leaks and valve damage. If the cap is missing or not snug, contaminants can enter and air can slowly escape, undermining the inflation you’ve just confirmed. Tread depth and lug nuts are important parts of a thorough inspection, and the general direction of the tires isn’t something you adjust during a quick pre-drive check. But the cap on the valve stem directly supports maintaining the correct pressure, making it the best match for this question.
