Should You Release Air from Tires with High Pressure in Summer?
3 Answers
If the tire pressure is indeed high in summer, exceeding the recommended value by more than 0.3 bar, it is advisable to slightly release some air from the tires. However, when doing so, ensure that the air is released evenly. Make sure the air pressure is balanced between the two front wheels and the two rear wheels. Avoid releasing air from only one side, as a significant difference in tire pressure between the two tires can cause the vehicle to pull to one side. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and pulling, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the 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 lead to internal cracks or blowouts, resulting in a flat tire.
High tire pressure in summer doesn't necessarily require immediate deflation. The expansion of air inside tires due to rising temperatures causes pressure increase, which is a physical phenomenon. I recommend first locating your vehicle's recommended tire pressure value, usually marked on the driver's door frame or in the manual, typically between 30-35 psi. Checking tire pressure during cool summer mornings gives the most accurate reading. If it's only slightly high by about 5 psi (e.g., reaching 38 psi on hot days), it might be fine; but if it exceeds by 10 psi or more, some air should be released. Excessive pressure accelerates center tread wear and increases blowout risks. I always remind friends to carry a tire pressure gauge for self-checks, saving trips to repair shops. When deflating, do it gradually - maintaining proper pressure enhances both safety and fuel efficiency. Develop a monthly checking habit, don't slack in winter either, to ensure tire longevity.
As someone who frequently drives long distances, I pay special attention to tire pressure changes in summer. Hot weather causes tires to expand significantly. Once while driving on the highway in high temperatures, the tire pressure warning light suddenly came on. After measuring, it had reached 40 psi, far exceeding the recommended value. I quickly released some air to bring it down to 35 psi before feeling at ease. Excessive tire pressure not only wears tires faster but also reduces grip, making them more prone to slipping on wet roads. Now, I've developed the habit of using a portable pressure gauge to check before heading out in the morning. If it's above the recommended value, I slowly release some air. But be careful not to over-deflate, as that can cause faster wear on the tire edges. Maintaining proper tire pressure in summer reduces the risk of blowouts and ensures more stable driving. Regularly checking this small detail gives peace of mind—don't wait until there's a problem to regret it.
