At what tire pressure does the Civic trigger an alarm?
2 Answers
The Honda Civic's tire pressure is around 2.2-2.5 bar. The 10th-generation Civic is equipped with a tire pressure monitoring system. Unlike directly measuring the tire pressure of each tire, this system monitors the vehicle and compares the rolling radius and rotational characteristics of each wheel and tire. If the tire pressure falls outside this range, an alarm will be triggered. Civic parameters: Fuel consumption: 5.0-6.4L, Body structure: 4-door 5-seat sedan, Engine: 1.0T/1.5T, Transmission: 6-speed manual/CVT, Drive type: Front-wheel drive, Fuel type: Gasoline. Hazards of too high or too low tire pressure: For tires, the pressure should neither be too high nor too low. Excessive tire pressure reduces the contact area between the tire and the ground, leading to poor grip, which affects the car's handling and driving stability. Insufficient tire pressure can cause wave-like deformation during high-speed driving, shortening the tire's lifespan and increasing the risk of a blowout. Introduction to standard tire pressure: According to the international GBT2978-2008 standard, the recommended tire pressures for different tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: Should not exceed 3.5 bar.
I've had an old Civic for five years and often need to take care of tire pressure issues. I remember that time on the highway when the tire pressure light suddenly came on, and the dashboard alarm went off. I checked and saw the pressure had dropped to 25 PSI, while the recommended level is 35! The alarm triggers when the pressure is 20-30% below the normal value. The Honda manual states that the alarm threshold is fixed, around 25 PSI, but it varies by model year. Low tire pressure not only wastes fuel but is also dangerous, increasing the risk of a blowout, so it's important to go to a repair shop for inflation promptly. It's recommended to check the pressure monthly, as it's more sensitive during hot summers—don't wait for the alarm to act. Safety comes first. After that lesson, I developed a habit of self-checking with a tire pressure gauge, which has made things much easier. Driving is no small matter; paying attention to tire pressure can make your car run smoother and go farther.
