Are you aiming to identify the cause of why your tire won’t remain inflated? Your tire may have a slow leak in tire caused by persistent tire deflation. A tire with a slow leak loses air pressure over time, which can reduce fuel efficiency and increase the risk of a blowout. Additionally, it impairs your car’s handling, making it more difficult to react to emergencies or navigate adverse weather.

In this article, we will show you how to detect a slow leak in a tire and how to fix it. Keep reading to learn more!

Common Causes Why There Is A Slow Leak In Tires

A tire can start losing air over time for different reasons. Let’s discuss some of the most common reasons for a slow air leak from your tire.

A Puncture in the Tire

You could anticipate that if your tire is punctured while driving, it will go flat right away. However, most tire-puncturing objects stay buried in the tire’s grooves, which causes air to escape very slowly. That is true especially for minor punctures. As a result, many consumers are unaware that their tire is losing air. In order to prevent further, more expensive tire damage down the road, tire punctures must be repaired as soon as they happen or are seen.

Damages on the Wheel

Wheel damage is another factor that might cause slow tire leakage. This deterioration often occurs where the tire bed meets the tire rim. Frequently, driving over potholes, speed bumps, or even curbs will result in it. Your tire pushing away from the surface of the wheel during these impacts on your tires might distort the metal surface of the wheel.

Worn Out Valve Stem

The part of your tire that permits it to inflate and deflate is called the valve stem. Valve stems are susceptible to wear or damage from environmental factors including weather or debris. As a result, your tire may start to leak since it can no longer hold air.


Apply water

You may easily conduct a test using water and liquid soap if you can’t read your TPMS sensor. Spray the entire tire with a mixture of water and liquid soap after mixing them in a spray bottle. While you’re doing this, keep an eye out for an area where the soapy water starts to create bubbles. You can use this method to locate the tire puncture.

Examine the TPMS sensor

Your tires’ air pressure is measured by the tire pressure monitoring system (TPMS). One of your tires may be underinflated if your TPMS is illuminated. Refill your tires with air, then check the TPMS sensor for the following week. If the light comes back on, you most likely have a slow leak.

Use manual pressure readings

Weekly manual tire pressure checks are still crucial even if your car has a TPMS sensor. You most certainly have a slow leak if you frequently notice that one of your tires is always under-inflated.


How To Effectively Fix A Tire Leak 

It’s time to figure out how to fix the air leak in your tire now that you have located it. You have three options for fixing something: the tire, the rim, or the valve stem. It’s important for you to understand, however, that not all tire and wheel damage can be fixed.


If the leak was brought on by a damaged valve stem, certain cars could also need a valve replacement. Patches or plugs may be used to fix a puncture if it is reasonably minor and discovered quickly. Patches are frequently used for minor holes, whereas plugs must be inserted into larger holes. Plugs and patches, when applied by an expert, can be long-lasting fixes.


There are various repair methods available that can provide you a short-term solution. This will give you enough time to find the closest automotive shop, where a team of experts will be able to precisely identify an air leak and fix it.
