The air pressure is 2.5. What's wrong with running the expressway tomorrow? What's everyone's air pressure?

Normal tire pressure When the weather is cold, the tire pressure should be adjusted appropriately. Long-term low tire pressure driving will aggravate tire wear. Tire pressure is generally slightly lower under the guidance of the manufacturer. The overall comfort of the vehicle has taken into account 2.3 in summer and 2.5 in winter, and tire wear is also within the normal range. I suggest you try this tire pressure standard. Please adopt it.
