What is the general tire pressure in kPa?

Tire pressure is between 240 to 250 kPa. Here is an introduction about tire pressure: 1. Tire pressure is the blood pressure of a car. The level of tire pressure plays a crucial role in the performance and power of the vehicle. Both too high and too low pressure will shorten the service life of the tire. 2. The tire pressure is an indicator of the vehicle's load capacity. The load capacity of the vehicle depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity.
Tire pressure typically ranges between 200 to 250 kPa. Based on my experience, maintaining around 240 kPa is suitable for regular sedans, while SUVs might require slightly higher pressure at 250 kPa. The most crucial point is to check the pressure when the tires are cold, meaning after the car has been parked for several hours, as heat from driving can increase pressure and lead to misleading readings. If the pressure is too low, say below 200 kPa, the tire contact area increases, rolling resistance rises, naturally leading to higher fuel consumption, and faster wear on the tire edges. Conversely, if the pressure is too high, exceeding 250 kPa, the ride becomes noticeably bumpier with reduced grip. It's also important to consider the vehicle type. My compact car's manual recommends 230 kPa, and there's a small label on the door frame indicating this. I advise new car owners to check there first rather than guessing. For routine maintenance, checking once a month is sufficient, which can be done at gas stations or with a personal tire pressure gauge. Safety comes first, as incorrect tire pressure can affect braking distance and handling.
