What Causes Sudden Tire Pressure Drop in Summer?
2 Answers
Sudden tire pressure drop in summer may be caused by temperature effects or potential tire performance issues. The exact cause requires professional inspection and troubleshooting. Below are specific details about car tire pressure: 1. Effects of abnormal tire pressure: When tire pressure is too high, it increases the risk of tire blowouts and reduces driving stability at high speeds. When tire pressure is too low, it increases fuel consumption and accelerates tire wear. In such cases, the spare tire should be promptly replaced, and the tire should be inflated at an auto repair shop to prevent safety hazards while driving. 2. Normal tire pressure range: Generally, normal car tire pressure ranges between 2.3bar-2.8bar. Both excessively high or low tire pressure will adversely affect vehicle operation.
This week I experienced a sudden drop in summer tire pressure and clearly felt the steering wheel become heavier while driving. The main reason is that hot weather causes tire rubber to soften, making it more susceptible to punctures from nails or debris on the road. Especially in summer, high road temperatures can cause uneven tire expansion, potentially forming tiny cracks that allow air to slowly leak out. Another common factor is poor valve core sealing, as high temperatures can deform and weaken the sealing rings. I recommend stopping immediately to check, using a portable tire pressure gauge to measure and locate any leaks. If not repaired promptly, it not only affects driving stability but also increases the risk of a blowout, which is especially dangerous during summer long-distance trips. It's best to develop a habit of checking tire pressure every two weeks, parking in shaded areas to reduce sun damage and avoid unnecessary trouble.
