| Moderately out of round (3-5mm) | Tire turning + dynamic balancing | 150-300 yuan | 1-2 years |
| Severe deformation (>5mm) | Replace tires/wheels | 500-2000 yuan | More than 3 years |
3. Recent hotly discussed cases
1.New energy vehicle tire problems highlighted: A user on an electric vehicle forum reported that due to the large instantaneous torque and uneven wear of the rear wheels, the out-of-round condition is 30% higher than that of fuel vehicles.
2.DIY repair tutorial controversy: The "jack correction method" popular on the short video platform was pointed out by professional technicians that it may aggravate the deformation of the wheel hub. The relevant video has been played more than 2 million times.
4. Suggestions on preventive measures
1.Regular inspection: It is recommended to check tire wear every 5,000 kilometers, using the coin test method (insert a coin into the tire tread, if the entire coin surface is visible, replace it).
2.Scientific driving: Avoid sharp acceleration/sudden braking. Data shows that gentle driving can extend tire life by 40%.
3.Professional maintenance: Four-wheel alignment every 10,000 kilometers can reduce the risk of abnormal wear by 80%.
5. Industry trends
According to the latest statistics, tire complaints in the third quarter of 2023 increased by 15% year-on-year, of which "out-of-round vibration" problems accounted for 23% of the total complaints.
