Urgency:Service soon
Is it safe to keep driving?
Yes, briefly, unless a tire is visibly flat. Check the pressures at the next stop; an under-inflated tire overheats and can fail at highway speed.
Likely causes
- Cold weather dropping pressure (about 1 psi per 10°F)
- A slow puncture
- A sensor battery that has run down (flashing light)
- Pressures not reset after a tire change
Typical repair cost (US)
$0 – $250
Free air at the low end; a puncture repair or a new TPMS sensor at the high end.
A typical range, not a quote. Actual cost depends on the car, the shop and the fault.
What to do now
- Check all four tires against the pressure on the door-jamb sticker — not the number on the tire sidewall.
- If one tire keeps losing pressure, have it checked for a puncture.
- A light that flashes for a minute then stays on means a sensor fault, not low pressure.
