What is the normal tire pressure for a Fit?
2 Answers
The normal tire pressure for a Fit is 2.4-2.5 bar. According to the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: Should not exceed 3.5 bar. Hazards of over-inflated tires: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Causes excessive stretching deformation of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, and impacts can cause internal cracks and blowouts, leading to tire bursts.
After driving the Fit for so many years, I usually keep the tire pressure around 2.3-2.5 kg. Measuring when the car is cold gives the most accurate reading, and checking before heading out in the morning is the most reliable. Don't forget the spare tire—it's best to inflate it to 2.8 for peace of mind. The sidewall of the tire shows the maximum limit, but don't inflate to that level—it's the limit for full load. In summer, tire pressure can rise by 0.2 on the highway, which is normal, and in winter, it may drop by 0.3 when temperatures fall. Last week, I used a mechanical gauge to check my friend's Fit—if the deviation across the four tires exceeds 0.3, it's dangerous as the steering may feel unstable. Checking for abnormal wear in the center tread can also help determine if the tire pressure is correct.
