What are the reasons for high tire pressure?
2 Answers
The reasons for high tire pressure are: 1. Over-inflation of the tire leads to high tire pressure readings; 2. Tire dynamic imbalance with excessive deflection causes high tire wear temperature and increased tire pressure; 3. Inaccurate four-wheel alignment of a particular wheel. Hazards of high tire pressure: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Causes steering wheel vibration and deviation, reducing driving comfort; 3. Accelerates localized wear of the tread center pattern, shortening tire lifespan; 4. Increases vehicle vibration, indirectly affecting the lifespan of other components. Factors affecting tire pressure: 1. Seasonal factors: In winter, adjust tire pressure based on the standard tire pressure, increasing it by 0.2 bar; in summer, if the car is parked outdoors, the pressure can be 0.1 bar lower than the standard to prevent high-temperature blowouts; 2. Tire pressure measurement environment: Cold tires and hot tires have different pressures, with a typical difference of 0.3 bar to note during measurement.
As someone who frequently commutes by car, I once encountered the issue of overinflated tires. During a gas station visit, the attendant accidentally overinflated them, resulting in a noticeably bumpy ride where even speed bumps felt jarring. Later, I learned that aside from inflation errors, rising summer temperatures can also cause the air inside tires to expand, increasing tire pressure. Excessive tire pressure leads to rapid wear at the center of the tire, shortening its lifespan, while also reducing handling performance and increasing the risk of skidding during turns. I recommend checking tire pressure during car washes using a standard tire gauge, referring to the values on the door sticker. If overinflation is detected, promptly release some air with a small tool—this can save significant money on tire replacements. Since adopting this habit, my car drives more smoothly, and tire longevity has improved.
