Quick answer
Salazar Roadside Assistance provides mobile air service and TPMS diagnosis across DFW. We set every tire to the pressure on your door placard, look for the leak causing the light, and identify failed or dead TPMS sensors so you know whether it is a leak or a sensor.
Why the light comes on in Texas
Air pressure moves roughly 1 PSI for every 10 degrees of temperature change. The first cold snap after a Texas summer sets off pressure lights across the whole Metroplex on the same morning — often with no leak at all.
A light that will not go out is telling you something
If the light stays on after the tires are correctly inflated, either something is still leaking or a sensor has failed. TPMS sensor batteries are sealed and typically last five to ten years, so on an older vehicle a dead sensor is common.

Answers
TPMS & Air Service questions, answered
Why is my tire pressure light on when the tires look fine?
Tires can be 8-10 PSI low and still look normal. A cold morning after a hot week is the single most common cause in DFW.
What does a flashing TPMS light mean?
A flashing light for a minute at start-up usually means a sensor fault, not a pressure problem. A solid light means at least one tire is under pressure.
Can you replace a dead TPMS sensor?
We diagnose the sensor and tell you which one has failed. Replacement requires dismounting the tire, which we handle on site where the wheel allows.
What pressure should my tires be?
Use the placard in the driver's door jamb, not the number on the tire sidewall — that one is a maximum, not a recommendation.
Do you fill tires with nitrogen?
We use compressed air. Topping a nitrogen-filled tire with air is safe and does not damage anything.
