Does Uneven Tire Pressure Affect the Car?
2 Answers
The effects of uneven tire pressure are as follows: 1. Braking: It can cause differences in braking effectiveness, loss of control, difficulty or heaviness in steering, increased risk of tire blowouts, and higher fuel consumption. 2. Wear: Both excessively low or high tire pressure increase the likelihood of blowouts. Low tire pressure increases rolling resistance and fuel consumption, while causing severe wear on the inner and outer edges of the tire. 3. Lifespan: Pressure is critical to tire longevity; both over- and under-inflation shorten tire life. Under-inflation increases tire deformation, leading to cracks on the sidewalls, excessive heat buildup, accelerated rubber aging, and enlarged contact area that hastens shoulder wear. Over-inflation overstretches the tire cords, reduces elasticity, and increases the load on the tire during driving.
Last time I was driving, I noticed the steering wheel kept pulling to the left. After stopping to check, I found one front tire had too high pressure while the other was too low - it nearly caused an accident on the highway. Uneven tire pressure makes the car unstable and causes directional drift, especially feeling wobbly during turns. Not only that, but it causes uneven tire wear - the underinflated side wears out tread faster, reducing tire lifespan by more than half. What's worse, braking distance increases, making it impossible to stop in emergencies, plus it raises the risk of blowouts. For safety, I bought a portable tire pressure gauge and now check every two weeks to maintain equal pressure in all four tires (you can usually find the recommended values on a label in your car). Regular checks save money and give peace of mind - don't wait until problems arise to regret it.
