What to Do When Tire Pressure is Too High?

Tire pressure can become too high due to over-inflation, inaccurate four-wheel alignment, or excessive tire deflection. Below is a detailed explanation of the causes of high tire pressure: Over-inflation: Over-inflation leads to excessively high tire pressure. To address this, release some air. If you have a dial-type tire pressure gauge, unscrew the cap of the tire valve, locate the center of the valve stem, and press lightly. While referencing the tire pressure gauge, press the air release valve to let out air. Monitor the gauge until the tire pressure returns to normal. Inaccurate four-wheel alignment: Incorrect four-wheel alignment can cause uneven tire wear, leading to increased temperature and higher tire pressure. It is recommended to visit a 4S shop for repairs. Excessive tire deflection: Excessive tire deflection results in increased tire wear and higher temperatures, thereby raising tire pressure. The deflected tire can be repositioned and secured properly.

Don't panic if you find your tire pressure is too high, stopping to check it immediately is the best approach. Last week when I measured my tire pressure, I found the front tires had reached 3.1 bar, significantly exceeding the recommended standard of 2.3 bar listed on the door label. I quickly connected the emergency air pump from the trunk to the deflation valve, releasing air while measuring with a mechanical tire pressure gauge, slowly adjusting it down to 2.4 bar before stopping. When deflating, avoid hot road surfaces—it's best to operate in a shaded area. Excessive tire pressure can lead to accelerated wear in the center of the tire, reduced grip, and even skidding during turns in rainy conditions. Extra caution is needed when driving at high speeds, as overly high pressure increases the risk of a tire blowout. It's advisable to carry a tire pressure gauge in your car and check monthly, especially during seasonal transitions when temperature changes cause noticeable fluctuations in tire pressure.

Overinflated tires can cause serious harm, as my personal experience has shown—it's no trivial matter. Excessive tire pressure reduces the tire's contact area with the road, increasing braking distance by about 20%. I once nearly rear-ended another car in the rain because of this. It also worsens shock absorption, making the ride uncomfortably bumpy, and can halve the tire's lifespan. The solution is simple: when the car is cold (like before your morning commute), gently press the valve core with a key to slowly release air while monitoring the tire pressure display. Remember, the standard tire pressure is usually listed on the door frame or inside the fuel cap, varying by vehicle model. It's advisable to check every two weeks, especially during seasonal transitions between winter and summer.

Dealing with overinflated tires is actually quite simple. Last month, my car was riding particularly rough, and the tire pressure monitoring app on my phone showed the right front tire at 280kpa, significantly higher than the standard 230kpa. I simply bought a metal valve wrench at a convenience store, unscrewed the valve cap, and gently pressed the wrench core to start releasing air. I stopped when it dropped to around 240kpa—this trick works well for slight overinflation. Remember to release the air in stages, checking the pressure after each release to ensure it's even. Overinflated tires not only make the ride uncomfortable but can also cause tire bulging over time. Beginners are advised to keep an electronic tire pressure gauge handy for more accurate readings. Don't forget, the tire pressure label is usually located on the driver's side door frame; if you can't find it, check the vehicle's manual.
