Tire pressure is generally considered normal between 2.2 and 2.5 kilopascals. In spring, when the temperature is around 20 degrees Celsius, the tire pressure should typically be maintained between 2.3 and 2.5 kilopascals. However, as the temperature and road surface temperature gradually rise, especially during high-speed or long-distance driving, the tire pressure can easily increase, which may lead to tire blowouts. In summer, road surface temperatures can reach 60-70 degrees Celsius. If the tire pressure is too high while driving, even slight contact with weak spots on the tire can easily cause a blowout. Here is some information about tire pressure: 1. Tire pressure, strictly speaking, refers to the air pressure inside the tire. In terms of car , the engine is the heart of the car, and its damage can lead to the end of the car's life. Similarly, tire pressure is like the blood pressure of the car. The level of tire pressure plays a crucial role in the car's performance and power. 2. Air pressure is the lifeline of a tire. Both too high and too low pressure can shorten the tire's lifespan. Low pressure increases the deformation of the tire body, making it prone to cracks on the sidewalls. It also causes flexing movements, leading to excessive heat, rubber aging, fatigue of the cord layers, and cord breakage. Additionally, it increases the tire's contact area with the ground, accelerating wear on the tire shoulders. High pressure, on the other hand, causes excessive stretching and deformation of the tire cords, reducing the tire body's elasticity. This increases the load on the car while driving, and impacts can lead to internal cracks and blowouts. High pressure also accelerates wear on the tire tread and reduces its resistance to rolling.

When I drive my sedan, I always pay attention to the tire pressure. The maximum pressure a sedan tire can withstand is usually between 35 to 44 psi, which is approximately 2.4 to 3.0 bar. The exact value can be found on the sidewall of the tire, like on my car where it says 'max press 44 psi'. However, this is not the pressure you should use daily; it's just the upper limit. If the pressure is too high and exceeds this number, the tire is more likely to burst or lose control at high speeds. Underinflation also causes problems. Last time I neglected it, the pressure was only 25 psi, resulting in faster wear on both sides of the tire and increased fuel consumption. I recommend maintaining the manufacturer's recommended pressure, usually between 30 to 35 psi, which can be found on the door frame or in the user manual. Temperature changes affect tire pressure; it rises in the summer heat and drops in the winter cold. Checking it every two weeks with an inexpensive pressure gauge takes just a few minutes and ensures safe driving.

I think tire pressure is particularly important for driving safety, especially when traveling with family. The maximum pressure that car tires can withstand is mostly between 240 to 300 kPa, approximately equal to 35 to 44 psi. Although this number seems high, you should never inflate them to the upper limit when actually driving. I personally experienced this once when the pressure was overinflated to 38 psi, resulting in strong bumps on the highway and poor handling. The recommended pressure values are usually found on the door label or in the owner's manual, generally between 30 to 35 psi. If the pressure is too low, the tires heat up quickly, increasing the risk of a blowout and also raising fuel consumption. I check it every month using a digital pressure gauge bought from the supermarket—simple and accurate. After rain, when the road is slippery, extra attention is needed as unstable tire pressure can affect braking distance.

From my experience, tire pressure directly affects fuel consumption and tire lifespan. Passenger car tires can withstand a maximum pressure of around 44 psi, but that's just the safety limit. For normal driving, maintaining pressure around 32 psi is most appropriate. Overinflation causes excessive wear in the center of the tire, while underinflation leads to uneven wear on both sides. I pay attention to this regularly and check the pressure whenever I refuel. Tire pressure drops when temperatures decrease, so regular adjustments are necessary. Simply put, maintaining proper pressure saves fuel and ensures safety.

When discussing car tire pressure, I always remind everyone not to focus solely on the maximum load capacity. It usually ranges between 35 to 44 psi and is marked on the tire sidewall. However, you should actually use the manufacturer-recommended 30 to 35 psi. I make it a habit to check every two months, as pressure fluctuates significantly with temperature changes. Avoid overinflating in hot weather and add a bit in cold conditions to ensure stable handling. Underinflation increases rolling resistance, leading to unnecessary wear and higher fuel consumption.

The maximum pressure for car tires, as I've checked, can withstand around 35 to 44 psi. For daily driving, I consistently maintain them within the recommended range of 32 to 36 psi. This is crucial for both comfort and handling—low pressure makes the ride bumpy, while high pressure makes the steering wheel heavier. I use a mobile app to remind myself to check monthly, and keeping a portable tire pressure gauge in the car is sufficient. I always check before driving in rain, snow, or long trips to prevent unexpected risks.
