What Causes Low Tire Pressure Warning?

[KimberlyAnn]

Low tire pressure warning may be caused by: insufficient air pressure, tire damage leading to air leakage, or low ambient temperature. Tire pressure refers to the air pressure inside the tires. In automotive maintenance terms, while the engine is considered the heart of a car (whose failure would mean the end of vehicle's life), tire pressure acts as the blood pressure of a vehicle. The level of tire pressure plays a crucial role in a car's performance and power output. Air pressure is the lifeline of tires - both excessive and insufficient pressure will shorten tire lifespan. Insufficient pressure increases tire body deformation, makes sidewalls prone to cracking, generates excessive flexing movement leading to overheating, accelerates rubber aging, causes fatigue in cord layers and breakage of ply cords. It also enlarges the tire's contact area with the ground, accelerating shoulder wear.
