If tire pressure rises above the recommended cold inflation level after continuous highway operation, a commercial vehicle driver should bleed air from the tire until it returns to the cold inflation specification.
Cevap: Cevap
Cevap
False. Air pressure must never be bled from hot or warm tires because internal pressure normally increases with operating heat, and releasing air will cause severe underinflation when the tire cools.
Air pressure naturally increases as tires warm up from highway driving. Commercial drivers must never bleed air from warm or hot tires, as doing so leaves the tires severely underinflated when they cool, creating a severe blowout hazard.
Adım Adım Çözüm
Anahtar Kavram
Operating temperature increases tire pressure naturally, and air must never be bled from hot tires.
