High tire pressure can easily cause a blowout, so in hot summer weather, tire pressure should be deflated frequently to reduce it.

ANSWER · B

Both insufficient and excessive tire pressure are bad - they cause tire wear and serious cases pose a danger. Frequently lowering tire pressure can leave it low or insufficient, which reduces tire durability and increases rolling resistance, hurting fuel economy. Excessive tire pressure reduces grip, causing irregular wear and blowouts.
