Is a tire pressure of 220 normal for a small car?
1 Answers
A tire pressure of 220 is normal and not too low, but to save fuel consumption, it is recommended to inflate the tire pressure to 230. Excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear on the central tread pattern of the tire, shortening its lifespan; increased body vibration indirectly affects the lifespan of other components; when encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks and blowouts due to impact, leading to a tire burst. Insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; it can cause heavy steering and deviation, posing safety risks; it increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; the friction between the tire and the ground multiplies, rapidly raising tire temperature, softening the tire, and drastically reducing its strength, which can lead to a tire burst during high-speed driving; insufficient tire pressure increases tire body deformation, making the tire side prone to cracks and causing flexing movements, leading to excessive heat, rubber aging, fatigue in the cord layer, and cord breakage, while also increasing the tire's contact area with the ground, accelerating shoulder wear.
