Why is My Tire Pressure Light On After Getting New Tires

For every car, there’s required tire pressure and when the pressure of a car’s tire goes too low and makes driving unsafe, the TPMS relays this information by sending a message to the car’s computer which turns on the pressure light

The TPMS means tire pressure monitoring system and it monitors the tire pressure for all the tires and notifies the driver, that’s when the pressure light comes on.

However, why is my tire pressure light on after getting new tires?

The pressure light comes on only when there is a problem with the car’s tire pressure so if the light comes on after replacing your tire with a new one, it could be as a result of overinflation or under-inflation by the shop where you got it.

Can Tire Pressure Light Still Be On After Getting New Tires?

Yes, the tire pressure light can still be on even after the former tires have been replaced with new ones.

Most times when the tire pressure light comes on, it’s because the tire pressure monitoring system has detected an abnormality in the tire system.

Although there are times when there can be malfunctions from various parts of the system but this is not the cause in most cases.

The Tire pressure monitoring system makes the pressure light come on and this happens when it notices any irregularity in the pressure of the tires.

New tires sometimes may not have the right pressure that your car needs so when the tire pressure light comes on after a new replacement, you can just check the tire pressure of all the tires of your car, you might find that they’re not all equal.

If even after checking the tire pressure, the light doesn’t come off you should get your car to a repair shop so they can check if all the sensors are in a good condition.

Why is My Tire Pressure Light On After Getting New Tires?

The tire pressure light staying on even after the old tires have been replaced with new ones can be caused by a number of reasons.

As reiterated earlier, it could be as a result of the new tires being under or over-inflated which would definitely cause the tire pressure monitoring system to send a message to the main system so the light can come on.

Sometimes, after replacing a tire, you might need to reset the tire pressure monitoring system and the problem might just be fixed.

Every tire has a sensor that communicates irregularities directly to the car’s main computer system.

When a sensor gets faulty, it will start getting wrong readings for the tire’s air value and it will in turn send a message to the main computer system which puts the light on.

There are situations where the cause might just be that the last replacement that was gotten for the tire sensors was not compatible with your car, so it’ll keep sending wrong messages to the computer.

Then you might just need to get a replacement for such sensors so that everything goes back to normal.

This rarely happens but it could be as a result of the change in temperature of the tire, where the tires are stored are mostly cool so when the tire is brought out and fixed into the car, after moving, the air in the tires starts getting warm.

The warm air would cause the tires to expand and increase the pressure of the tire and when it’s more than the required pressure, the tire pressure light will come on.

How Do You Reset the Tire Pressure Light After Fixing New Tires?

Resetting the tire pressure light is not difficult at all and can be done in a few easy steps.

Normally, it is recommended that when you replace a tire, you should reset your tire pressure light so that the tire pressure monitoring system can acknowledge the new tire as one of its own and function properly.

Now, to reset your tire pressure light;

You need to drive your car at a speed of 50mph for about 10 minutes. This is done to reset the tire sensors when all the tires are moving at high speed the tire sensor if it’s not faulty would start reading normally again.

This should make the tire pressure light go off.

  • If doing it didn’t work? Not to worry, you can also try to reset the tire pressure light by switching off your vehicle first, then turning the key to “on”, do not start the engine.
  • Now hold the tire pressure monitoring system button and wait until the tire pressure light blinks three times, then release it.
  • Wait for about 20 minutes before you start your vehicle and allow it to run for about 30 minutes.

The last method by which you can reset your tire pressure light is over-inflating the tires, then deflating the tires, and finally, inflating them back to the recommended pressure.

If after trying all of these your tire pressure light doesn’t go off, you should get your car to a repair shop and get the entire tire pressure monitoring system checked so that any fault can be rectified.

Is it Ok to Drive with Tire Pressure Light On?

The tire pressure light is the least rated light of all the warning lights but this doesn’t make it okay to drive with the light on.

It is not safe to drive with the tire pressure light on for several reasons;

First, the tire pressure light is on as a result of an irregularity that has been detected in the tire pressure monitoring system.

It could be a low-pressure tire, and driving with a low-pressure tire is dangerous because it can cause your tires to wear out prematurely, and when a tire gets worn out while driving can cause you to lose control of the steering wheel.

Driving with your tire pressure light on also puts you at risk of getting a tire blowout and this can damage the tread of your vehicle.

Will Tire Pressure Light Go Off On Its Own?

The tire pressure sometimes experiences a malfunction, maybe when the battery gets low and this can cause it to send signals to the main computer for the tire pressure light to come on.

If this is the cause, the lights will go off after a few minutes, you should already know that you need to replace the battery but if you keep driving and the light doesn’t go off after driving for about 10 minutes.

You should immediately park your car and do a quick check for leaking tires or get your car to a repair shop as soon as you can.

Final thoughts

The tire pressure light mostly comes on when the tire pressure is not consistent with the normal pressure levels so you should not ignore it when it comes on. As reiterated earlier, it is the least rated but this doesn’t mean it should be ignored.
