What is the appropriate tire pressure for the new Focus?

According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. Tire pressure, strictly speaking, refers to the air pressure inside the tire. What is the normal tire pressure in winter? In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2bar. What is the normal tire pressure in summer? Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures.
For the tire pressure of the new Ford Focus, as a frequent driver, I recommend maintaining it between 32-35 psi under normal conditions. The exact value should be checked in your vehicle's manual or the label on the door frame, as those provide the most accurate specifications. Too low tire pressure can easily wear out the tire sidewalls and may cause instability when cornering; too high pressure, while fuel-efficient, increases bumpiness and affects comfort. Adjustments are necessary with weather changes: in summer, tire pressure rises quickly due to heat, so you can slightly release air to around 32 psi; in winter, cold temperatures reduce tire pressure, requiring inflation to about 35 psi. I make it a habit to check with a portable tire pressure gauge monthly and before long trips, which can extend tire life to 4-5 years and save about 10% on fuel costs. Never estimate by kicking the tires—it's highly unreliable. Investing in a tire pressure gauge that costs just a few dollars and keeping it in the glove box for easy access is both safe and economical.
