However, a severely damaged wheel bearing *could* indirectly lead to a low tire pressure light *if* the damage causes a slow leak. For example, if the bearing is severely damaged and the damage punctures or compromises the tire, air could leak out, eventually triggering the light. This would be a relatively rare and severe failure, though.
More likely, a failing wheel bearing will exhibit other symptoms first, such as:
* Noise: A grinding, humming, or rumbling sound, especially when turning or at higher speeds.
* Vibration: A noticeable vibration in the steering wheel or the vehicle itself.
* Wobble: A feeling of looseness or instability in the steering.
* Uneven tire wear: This is a later stage effect.
If your low tire pressure light is on, check your tire pressures first. If a wheel bearing is failing, you'll likely notice some of the symptoms listed above *before* your tire pressure gets low enough to trigger the warning light.
