轮胎只看花纹深浅还不够：怎样记录偏磨，决定是否需要进一步检查

Uneven wear is evidence to investigate, not a diagnosis by itself. Label photographs by wheel position and record fitment, installation mileage, rotation and alignment history. Have inaccessible inner surfaces checked safely. Consistent inner, center and outer tread measurements can help track change, but do not replace professional assessment or applicable limits. Mention pulling, impacts and speed-related vibration so the workshop can select relevant tests. Tire rotation depends on the actual staggered or directional setup. Bulges, exposed structural material, rapid pressure loss and severe abnormal wear require prompt attention rather than waiting for a routine service.
