What is the suitable tire pressure for cars in summer?
2 Answers
In summer, the normal tire pressure for cars is generally suitable between 2.2-2.4 bar. As the temperature and road surface temperature rise, the tire pressure can easily increase during high-speed or long-distance driving. Excessive tire pressure can lead to loss of braking control and may cause tire bursts when encountering road protrusions or depressions. Hazards of excessive tire pressure: Reduced tire friction and adhesion, 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; Overstretches the tire cords, reducing tire elasticity and increasing the load on the car during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, leading to internal cracks, bursts, and blowouts.
I remember paying special attention to tire pressure in summer while driving, as high temperatures can easily cause issues. Generally, the recommended values in the owner's manual or on the door frame are the most reliable, usually between 30 to 35 PSI. In summer, as temperatures rise, the air expands, causing tire pressure to be 2-4 PSI higher than when the car is cold. I recommend measuring it in the early morning when temperatures are lower, maintaining the recommended value but possibly keeping it slightly lower by 1-2 PSI to avoid the risk of a blowout. Never arbitrarily increase the pressure, as this can lead to faster wear in the center of the tire and make the car harder to control while driving. I regularly check with a tire pressure gauge to ensure the front and rear tires are consistent, which enhances both safety and fuel efficiency. Experience has taught me that improper tire pressure can lead to accidents, big or small, so I always handle it with care—better safe than sorry.
