A tire pressure light that stays on after a tire change usually means a sensor was not reset, relearned, or has failed. Miami Tire Shop, at 3151 NW 17th Ave in Miami, FL, can look at TPMS sensors. Call with your make, model and year so sensor availability can be confirmed before you come in.
The amber tire-shaped light has two meanings. If it stays solid, one or more tires are low or a sensor is not reporting. If it blinks for about a minute at startup and then stays lit, the system itself has a fault, and that usually points at a sensor.
Check the pressure with a gauge first. In Miami heat, tire pressure rises through the day and drops overnight, so a light that shows up early and clears by afternoon is often just a low tire.
Does a tire change need new TPMS sensors?
Not always. A sensor mounts inside the wheel on the valve stem, so it comes off with the tire. A careful tech reuses a working sensor, but a damaged valve stem or a dead sensor means replacing it.
Ask the shop whether they will check each sensor before the tire goes back on, not after. Finding a dead one with the tire already mounted means doing the job twice.
What is a sensor relearn and why does my car need one?
The car's computer remembers which sensor sits at which corner. After a rotation or a sensor swap, it has to be told again. Some vehicles relearn by driving, others need a scan tool or a specific procedure.
That is why the light can stay on right after a perfectly good tire job. Ask whether the quote covers the relearn.
What should I have ready when I call?
Your make, model and year, and whether the light is solid or flashing. Sensors differ by vehicle, so availability is worth confirming by phone with Miami Tire Shop before you drive over.
Can I drive with the TPMS light on?
Yes, for a short trip once you have confirmed the tire is not flat, but do not ignore it. A real slow leak and a dead sensor look identical from the driver's seat until the pressure is checked.
Can one bad sensor be replaced alone?
Usually, yes. The catch is that the replacement has to be programmed to your vehicle, so ask whether that is included.
Does a spare tire have a sensor?
On many vehicles it does not, so the light may not warn you about it. Look at the pressure yourself every so often.
