What is Cold Tire Pressure?
2 Answers
Cold tire pressure refers to the air pressure inside tires at normal temperature (room temperature), typically between 18~24 degrees Celsius. Related information: 1. Tire pressure: Strictly speaking, tire pressure means the air pressure inside tires. In terms of car maintenance, the engine is the heart of a car - engine failure would lead to the end of a car's life, while tire pressure is like the blood pressure of a car. The level of tire pressure plays a crucial role in a car's performance and power. 2. Methods of tire pressure monitoring: Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure, then transmit the pressure information from inside the tire to a central receiver module via wireless transmitters, finally displaying the tire pressure data for each tire.
I've been driving for twenty years and fully understand the importance of cold tire pressure. It refers to the air pressure measured when the tires have cooled down after the car has been parked overnight or for several hours without moving. This value is the most accurate because when tires heat up from driving, the internal gas expands, leading to misleadingly high readings. You can find the recommended value on the door frame or in the user manual—just set it accordingly. I learned the hard way when I was younger; incorrect tire pressure made high-speed handling unstable, and I once almost had a blowout. Now, I make it a routine to check every month in the morning, using a tire pressure gauge to see if everything's normal. Properly set tire pressure can also save about 5% on fuel and extend tire life—it's such a relief. Never wait until the car is warm to measure, as the error margin is large. Safety comes first.
