You’re heading across Panama City Beach when that small yellow tire-shaped light appears on the dashboard. Should you pull over immediately, or can you keep driving?

The tire pressure warning light should not be ignored. It usually means one or more tires has lost enough air to affect handling, braking, tire life, or fuel efficiency. In many cases, the fix is simple. But a low tire can also point to a puncture, valve problem, or damaged tire that needs professional attention.

Here’s what the TPMS light means, what you can safely check yourself, and when to look for tire repair near me.

What does the tire pressure warning light mean?

TPMS stands for Tire Pressure Monitoring System. Your vehicle uses this system to monitor tire pressure and alert you when pressure drops below a safe range.

The warning symbol usually looks like a flat tire with an exclamation point in the center. Depending on your vehicle, the system may use:

• Direct TPMS: Sensors inside the wheels measure actual tire pressure.
• Indirect TPMS: The vehicle uses wheel-speed sensors to detect when one tire rotates differently from the others.

The light generally comes on when a tire is significantly below the pressure listed on your vehicle’s door-jamb placard. That number: not the maximum pressure printed on the tire sidewall: is the correct inflation target for your vehicle.

TPMS is a helpful backup, but it does not replace checking your tires with a gauge. A tire can be losing air before the dashboard warning appears.

Is it safe to drive with the TPMS light on?

That depends on what your tires look and feel like.

If the light comes on and the vehicle feels normal, drive slowly and smoothly to a safe location. Avoid unnecessary highway driving until you check the tires. A short trip to a nearby service shop may be reasonable if the tire is not visibly low or damaged.

Stop driving as soon as it is safe if:

• A tire looks flat or noticeably low.
• The steering feels unstable.
• The vehicle pulls strongly to one side.
• You feel vibration, thumping, or wobbling.
• A tire has a bulge, sidewall cut, or exposed cord.
• The warning light appears with other handling or brake warnings.

Driving on a severely underinflated tire can create heat buildup and damage the sidewall. It can also reduce traction and increase stopping distance. If the tire is flat or badly damaged, use roadside assistance rather than continuing to drive.

How can you check your tire pressure?

Checking tire pressure takes only a few minutes. For the most accurate reading, check the tires when they are cold, preferably before driving or after the vehicle has been parked for several hours.

Follow these steps

1. Find the recommended PSI.
   Look for the tire-pressure label inside the driver’s doorjamb or check your owner’s manual.

2. Remove the valve cap.
   Press a reliable tire gauge firmly onto the valve stem.

3. Check all four tires.
   Do not inspect only the tire closest to the warning light. The system may not identify the exact tire, and more than one tire may be low.

4. Check the spare if your vehicle has a monitored spare.
   Some vehicles include a TPMS sensor in the spare tire.

5. Add air in small amounts.
   Recheck the pressure until it matches the vehicle manufacturer’s recommendation.

6. Replace the valve caps.
   Missing caps can allow dirt and moisture into the valve core.

After correcting the pressure, drive for several minutes. Many systems turn the light off automatically. Others require a reset or recalibration through the vehicle’s controls.

If the light stays on after the pressures are correct, schedule a tire and TPMS inspection. You may have a slow leak or a sensor issue.

Why did the TPMS light come on?

Could Florida weather cause low tire pressure?

Yes. Tire pressure changes with temperature. A cooler morning can lower pressure enough to trigger the light, even if the tire did not suffer a puncture.

Panama City Beach weather can also change quickly between hot pavement, cooler overnight temperatures, and long periods of air conditioning. That does not mean the warning is harmless. It means you should check the pressure rather than guessing at the cause.

Florida heat creates another concern: underinflated tires flex more than they should, which generates additional heat during driving. Keeping your tires at the recommended PSI helps support safer handling and more even wear.

Could a nail or screw be causing the warning?

Absolutely. Road debris can create a slow leak that is difficult to see from outside. A tire may look fine in the driveway but lose several PSI overnight.

If you recently drove through a construction area, parking lot, or shoulder, inspect the tread for a nail or screw. Do not pull the object out, because removing it can make the leak worse. Bring the vehicle to a qualified tire professional for an inspection.

Our tire repair and alignment service includes checking tires for punctures, uneven wear, alignment concerns, and other problems that may cause repeated air loss.

Could a recent tire rotation cause the light?

It is possible. Some vehicles need the TPMS sensors relearned or reset after a tire rotation, tire replacement, wheel change, or battery service.

A proper tire rotation also helps promote even tread wear. If you are searching for tire rotation near me, Express Tire & Auto Service welcomes walk-ins and can check the tires, adjust pressure, and verify the system as part of the visit.

What does a flashing TPMS light mean?

A steady TPMS light usually indicates that one or more tires is underinflated.

A flashing light, especially when it flashes for about a minute and then stays on, often indicates a TPMS system fault. Possible causes include:

• A weak or dead sensor battery.
• A damaged sensor.
• A sensor that was not programmed after tire service.
• A communication problem between the sensor and vehicle computer.
• A wheel-speed sensor or related system issue.
• A temporary spare without a compatible sensor.

You can still check the tire pressures manually, but do not rely on the warning system until the fault is diagnosed. TPMS sensors can be damaged during tire mounting or removal, so sensor service should be performed with the correct equipment and procedures.

What are common mistakes to avoid?

Don’t use the tire sidewall number as your target PSI

The number on the sidewall is usually the tire’s maximum allowable pressure, not the pressure recommended for your vehicle. Use the door-jamb placard or owner’s manual instead.

Don’t check only the visibly low tire

A tire can be several PSI below specification without looking flat. Check all four tires and the spare when applicable.

Don’t let air out of a hot tire

Driving heats the air inside the tire and can temporarily increase the pressure reading. Wait until the tires cool before making accurate adjustments.

Don’t keep resetting the light without finding the cause

A reset may temporarily turn off the warning, but it will not repair a puncture, leaking valve stem, damaged tire, or failed sensor. The light is a message: not the problem itself.

Don’t replace a tire before checking whether it can be safely repaired

Some tread punctures can be repaired, while sidewall damage and punctures near the shoulder may require replacement. We inspect the tire first and explain why a repair or replacement is recommended.

When should you bring your vehicle to a tire shop?

Bring your vehicle in promptly if the light returns after adding air, if the tire loses pressure repeatedly, or if you notice vibration, pulling, uneven wear, or unusual noise.

You should also have the system checked after:

• Installing new tires.
• Rotating the tires.
• Repairing a flat.
• Replacing a wheel or valve stem.
• Replacing the vehicle battery.
• Driving over a pothole or curb.
