What does it mean when the TPMS warning light is on?

[JuliannaDella]

The TPMS light is a tire pressure fault warning light, indicating that the pressure in one of the tires may be too low. Below is a relevant introduction to common faults encountered while driving: 1. Abnormal tire wear: Uneven wear occurs on a single side or specific area of the tire surface. Possible causes include insufficient or excessive tire pressure, excessive or insufficient toe-in or camber angle, unbalanced wheels, prolonged lack of tire rotation, loose wheel hub bearings, excessive wear of steering column pins or ball joints, improper driving habits, etc. 2. Noises from the front and rear axles or suspension: Possible causes include excessive wear or damage to moving parts of the front and rear axles or suspension, excessive bearing clearance or damaged bearings, loose fastening bolts, lack of oil or damage to shock absorbers. 3. Vehicle pulling to one side: The vehicle drifts away from the direction controlled by the steering wheel while driving. Possible causes include deformation of connecting parts of the front and rear suspension or frame, changes in the connection positions of the front and rear axles and suspension, misalignment of front wheel alignment, significant differences in tire pressure or wear between the two sides, etc.
