Is a tire pressure of 2.0 normal? Should it be refilled?
2 Answers
A car tire pressure of 2.0 bar is not normal and requires refilling. The normal tire pressure for a vehicle's tires is between 2.3 bar and 2.5 bar. Low tire pressure can lead to increased fuel consumption, reduced driving stability, and in severe cases, may cause tire blowouts. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and potential misalignment, which are factors detrimental to driving safety; Increases movement in various parts of the tire, leading to excessive rolling and abnormal heat generation; Reduces the functionality of the cords and rubber, leading to delamination or cord breakage, excessive friction with the rim, causing damage to the bead area and abnormal wear; The friction between the tire and the ground multiplies, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout; Increases tire body deformation, making the tire side prone to cracks, while generating flexing motion, leading to excessive heat, accelerating rubber aging, fatigue of the cord layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear. Methods for addressing insufficient tire pressure: If no damage is visible, simply inflate the tire to normal pressure and reset the tire pressure system; If a puncture is found during inspection, drive to a tire shop promptly for repair and reinflation; If the tire pressure warning reappears some time after inflation without any punctures, it may be due to air leakage caused by a deformed rim. It is recommended to check and replace the rim.
As a frequent driver who's still relatively new to this, I'm quite concerned about tire pressure. A reading of 2.0 is somewhat low - the normal range is usually between 2.2 and 2.5, as indicated on the sticker inside your car door frame. If it's only at 2.0, the tires will deform more while driving, leading to faster wear on highways and potentially higher fuel consumption. Just think about it - spending a few extra dollars on gas every 100 kilometers can be quite frustrating. It's best to quickly check with a tire pressure gauge or take advantage of free air refills at gas stations to reach the standard value. Remember that tire pressure tends to be higher in summer, and the most accurate readings are taken when the car is cold in winter. Make sure to check it every season - don't be careless, as small tire issues can accumulate over time. Keeping a portable air pump in your car is also quite practical for emergencies. In short, 2.0 isn't quite right - it's better to top it up for peace of mind, otherwise damaged tires will cost you more to replace.
