You top up the tyres at an ENOC station on Sheikh Zayed Road, but the yellow tyre symbol is still glowing the next morning. A TPMS warning light that stays on means either a tyre is still low or the monitoring system itself has a fault.
The tyre pressure monitoring system watches all four tyres and warns you before a soft tyre overheats or fails. Find out which kind of warning you have first. A proper tyre service can test both the tyres and the sensors.
TPMS Warning Light: Quick Answer
A TPMS warning light usually stays on because a tyre is still low or a slow puncture is letting air out. A dead sensor battery, a damaged sensor or a missed reset after inflation or rotation can also keep it lit.
Continental Tire explains that a solid light means a tyre is about 25 percent below its recommended pressure. A light that flashes for 60 to 90 seconds and then stays on points to a system fault, such as dead sensor batteries. Set all tyres to the door sticker pressure when cold, then reset the system.

Solid Light or Flashing Light
A solid light means low pressure. Continental Tire gives the example of a tyre rated at 35 psi, where the light usually comes on at about 26 psi or lower.
A flashing light is different. Continental explains that a light which flashes for 60 to 90 seconds at start up, then stays solid, signals a system fault. A trusted car mechanic near you can read the TPMS codes to see which sensor is at fault.
Temperature Swings and Pressure Readings
Tyre pressure changes with temperature. Continental notes that pressure drops by roughly 1 psi for every 10°F fall, which is about 5.5°C.
Dubai’s daily swings make this common. Tyres filled on a 45°C summer afternoon, or right after a long drive, read high when hot and low the next morning. Winter mornings in December and January can trip the light on a tyre that was borderline. Set pressures with the tyres cold, ideally first thing in the morning or during a regular car service in Dubai.
A Slow Puncture or Leaking Valve
If the light comes back a few days after you fill the tyres, one is losing air. Nails and screws from construction sites around Dubai South and Al Quoz are common causes.
Other leaks come from a corroded valve stem, a damaged sensor seal or a leaking bead where the tyre meets a kerbed rim. A dunk test or soapy water finds the leak. If a tyre goes soft quickly on the road, slow down, pull over safely and call roadside assistance.
Dead Sensor Batteries and Damaged Sensors
Most cars use direct TPMS, with a battery powered sensor inside each wheel. Continental notes that these batteries cannot be replaced and last about 5 to 10 years. When one dies, the whole sensor is replaced.
Sensors can also be damaged during tyre fitting or by puncture sealant from a can. A faulty receiver or wiring fault can also cause a flashing light, which falls under auto electrical repair. A TPMS tool reads each sensor’s signal, battery status and pressure.
The System Needs a Reset or Relearn
Some cars need a manual reset after you add air. Continental lists three methods. One is a reset button pressed with the ignition on and engine off. Others use a menu option and a short drive, or relearn on their own after 10 to 15 minutes above about 80 km/h.
After a tyre rotation, some systems must relearn which sensor sits on which corner. Cars with indirect TPMS, which uses the ABS wheel speed sensors instead of pressure sensors, almost always need a reset after inflation. A good car garage near you can run the relearn with a TPMS tool.
The Spare Tyre and Aftermarket Wheels
Some cars monitor the spare. Continental notes that an underinflated spare can keep the light on even when the four road tyres are fine.
Aftermarket wheels fitted without sensors will also trigger the light. When alloy wheels are refinished through paint and wheel repair, the sensors must be removed and refitted with care. A mobile mechanic can check pressures, including the spare, at home.
Why Choose Rapid Rev Garage for TPMS Faults
Rapid Rev Garage in Al Quoz is a sensible choice when the tyre light will not go out. Tyres, sensors and electrical faults are handled together.
Sensors Tested, Not Guessed
Each sensor’s signal and battery are read before any part is replaced, so only the failed sensor is changed.
Close to Sheikh Zayed Road
The workshop at Al Khail Gate, Al Quoz Industrial Area 2, is a short drive from Business Bay, Al Barsha and Downtown.
FAQ
Here are the questions Dubai drivers most often ask about the tyre pressure light.
Why is my TPMS light flashing?
A light that flashes for 60 to 90 seconds and then stays on means a system fault, such as a dead sensor battery.
Can I drive with the TPMS light on?
Check the pressures as soon as possible. A soft tyre overheats and can fail, especially in summer.
How long do TPMS sensors last?
Continental Tire puts sensor battery life at about 5 to 10 years. The battery cannot be replaced separately.
Does cold weather trigger the TPMS light?
It can. Pressure drops about 1 psi for every 10°F, roughly 5.5°C, so cool mornings can trip a borderline tyre.
What resets the tyre pressure light?
Inflate all tyres to the door sticker pressure when cold, then use the reset button, menu or a short drive.
Conclusion
A tyre light that stays on means low pressure, a slow leak, a dead or damaged sensor or a missed reset. Check pressures cold, look for leaks and have the sensors read if the light flashes.
