In hot weather, which action helps prevent tire failure?

• A. Replace tires daily
• B. Check mounting and air pressure before driving
• C. Ignore tire pressure
• D. Cool tires with water

Answer: (B)

In hot weather, heat increases tire pressure and the demand on the tire as it carries more load, so making sure the tire is properly mounted and inflated to the correct pressure before you drive is key to preventing failure. Proper mounting keeps the bead seated on the rim and the wheel balanced, reducing stress and vibration that can lead to bead or sidewall damage under heat. Correct air pressure prevents underinflation, which causes excessive flexing and extra heat buildup, a common path to overheating and blowouts when temperatures rise. The other options don’t address the real risks: daily tire replacement isn’t practical or necessary, ignoring pressure lets dangerous under- or overinflation go unchecked, and cooling tires with water doesn’t solve pressure or mounting problems.
