Is a Tire Pressure of 2.3 Suitable in Summer?
3 Answers
Summer tire pressure of 2.3 is not suitable. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5 bar. A pressure of 2.3 bar is below the minimum standard value, making it abnormal. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and easy deviation, which are factors detrimental to driving safety; Increases the movement of various parts of the tire, leading to excessive rolling and abnormal heat generation; Reduces the functionality of the cords and rubber, causing delamination or cord breakage, excessive friction with the rim, resulting in damage to the bead area and abnormal wear; Multiplies the friction between the tire and the ground, sharply increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts; Increases tire body deformation, making the tire side prone to cracks, while generating flexing movements, leading to excessive heat, promoting rubber aging, fatigue of the cord layer, cord breakage, and increasing the tire's contact area with the ground, accelerating shoulder wear.
I've been driving for over 20 years, and a tire pressure of 2.3 in summer works perfectly fine. This value gives me peace of mind during hot weather, but it's best to first check the recommended value on the sticker inside your car door frame, as different vehicles may have different requirements. High summer temperatures can cause tire pressure to rise, so if you set it to 2.3 when the tires are cold, it might increase to around 2.5 while driving, which is still within the safe range. For example, with my own car, I tested it just two months ago: 2.3 in the morning with cold tires, and after an hour on the highway, it rose to 2.5, with the tires feeling only moderately warm. A special reminder for new drivers: don't inflate your tires too much. When the ground temperature reaches 50-60 degrees Celsius under the midday sun, excessively high tire pressure can easily lead to blowouts. Regular checks are also crucial—use a simple tire pressure gauge at least once a month to measure all four tires.
Special attention should be paid to tire pressure settings in summer for safety, and the cold tire pressure of 2.3 is generally reliable. The recommended tire pressure for many cars ranges between 2.2 and 2.5, with 2.3 being the median value. It's advisable to measure the pressure in the morning before heading out, as the tires have completely cooled after the car has been parked overnight. If measured at noon, the readings will be significantly higher. Tire pressure is crucial for driving safety, as significant deviations can affect braking distance and steering precision. I usually take advantage of free pressure checks at gas stations and keep track of the readings each time. Before long highway drives in summer, it's best to double-check the tire pressure, as prolonged driving heats up the tires and causes a noticeable increase in pressure. Don't forget to check the spare tire as well—finding it flat when suddenly needed would be a disaster.
