What Tire Pressure Can Cause a Blowout?
2 Answers
Normal tire pressure is maintained between 2.2-2.5. When the tire pressure exceeds 30% above the recommended value, the likelihood of a blowout significantly increases. Sometimes, blowouts are not solely caused by high tire pressure; factors such as tire aging, puncture by hard objects, high summer temperatures, excessive road surface heat, or vehicle overload can also lead to blowouts. Below is a detailed introduction to the functions of car tires: 1. Support the entire weight of the vehicle and bear the load of the car. 2. Transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the vehicle's power, braking, and off-road performance. Together with the car suspension, they cushion the impact during driving and dampen the resulting vibrations. 3. Protect car components from severe vibrations and premature damage, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and fuel efficiency.
Incorrect tire pressure, whether too high or too low, can lead to a blowout—this is a common misconception! From my years of driving experience, the recommended tire pressure typically falls between 30 and 35 PSI, which can be found on the vehicle’s label or manual. If the pressure is too low, say below 25 PSI, the tire deforms excessively, generating intense friction heat, which over time damages the internal structure and causes a blowout. Conversely, if the pressure exceeds 40 PSI, the tire loses elasticity, and when encountering potholes or high-temperature road surfaces, the excessive tension can cause it to rupture directly. The key is to develop a habit of regular checks—measure the tire pressure once a month when the tires are cold using a simple tire pressure gauge. Weather changes also affect tire pressure: in summer, heat increases pressure, raising the risk, while in winter, cold reduces it, requiring inflation. Neglecting these small details can eventually lead to accidents! On the road, safety comes first—don’t skimp on time or cut corners.
