What to Do When Car Tires Show Excessive Tire Pressure?
3 Answers
Here are the solutions for when a car displays excessive tire pressure: 1. Generally, the tire pressure on the dashboard updates after driving a short distance. Try driving for a while to see if the data updates. If it doesn't, there may be an issue. 2. If the tire pressure is normal but still shows as high, it indicates a problem with the sensor, wiring, or the tire pressure monitoring module. 3. It is recommended to visit a 4S shop or repair shop for professional diagnosis using specialized equipment to read fault information before proceeding with analysis and repair. The impacts of excessive tire pressure are as follows: 1. Reduced tire friction and adhesion, affecting braking performance. 2. Causes steering wheel vibration and deviation, reducing driving comfort. 3. Accelerates wear on the central tread pattern, shortening tire lifespan. 4. Increases body vibration, indirectly affecting the lifespan of other components. 5. Overextends the tire cords, reducing tire elasticity and increasing the load on the car while driving. 6. Decreases wear resistance, making the tires more susceptible to punctures from sharp objects like nails or glass, leading to internal cracks, blowouts, and potential tire bursts.
Just the other day I encountered an issue with overinflated tires—right after coming off the highway, the tire pressure warning light came on. First, find a shaded spot to park and let the tires cool down, as hot weather naturally causes tire pressure to rise. Then, use a tire pressure gauge to check the actual reading—many cars have the recommended pressure values labeled on the door frame. If the pressure is indeed too high, use a small screwdriver or a dedicated deflation tool to slowly release the excess air. Remember, never rush and pull out the valve core directly, or you might end up launching the whole thing. Release a little air and check the pressure each time until it drops to the manufacturer’s recommended range. Make it a habit to check tire pressure when refueling or washing your car—it saves fuel and extends tire life.
After driving for over a decade, I've noticed that tire pressure tends to get too high during the spring-summer transition. Last month when my tire warning light came on and I didn't have a pressure gauge handy, I used a makeshift method: pressing hard on the tire sidewall with my fingers - if it felt rock hard and wouldn't budge, it definitely meant overinflation. I drove to the repair shop at the neighborhood entrance to have them release some air. Important note: never release air immediately after a long drive - wait until the tires cool completely before adjusting, as heat causes false high pressure readings. Those with modified wider tires need extra caution, as their pressure requirements may differ from factory specs. The scariest scenario is hitting bumpy roads with overinflated tires - the risk of blowouts skyrockets.
