How can I fix a slow leak in my car tire?

A slow leak in your tire can be difficult to detect at first, especially if the tire’s rubber is undamaged or if there is no nail protruding through the hole you have made. While this may eventually result in a flat tire, it does so more gradually than a sudden explosion.

This type of issue can arise even with a new tire or car, but it is also a typical repair that can be done at home sometimes. However, home repairs are not always viable, particularly when the rims are damaged.

  • How can I fix a slow tire leak in my car tire?

So, let’s dive in!

What are the common causes of slow tire leaks?

A gradual tire leak isn’t only an issue. Low tire pressure can be caused by a leak. Not to mention that driving on a tire with insufficient air pressure for an extended period of time might result in increased tire damage or even a dangerous burst. The following are the causes of slow tire leaks:

  • Sharp object
  • Wheel damage
  • Valve stem damage

Sharp object

It’s a common misperception that a flat tire means a flat tire immediately. However, in many circumstances, the object that caused the flat tire becomes trapped in the tire, preventing the air from quickly leaving. A flat tire, like any other type of tire leak, should not be ignored. The object either wears out or works its way out of the tire at some time.

Wheel damage

Damage to the area where the tire bead meets the rim is another typical cause of slow tire leaks. The motorist frequently causes this form of damage by hitting the curb, experiencing a bump at a fast speed, or hitting those dreadful potholes! The impact bends the wheel’s metal surface, which might cause the tire to separate from the mounting surface.

Valve stem damage

Worn or damaged valve stems are the third most prevalent cause of slow tire leakage. Your valve stems might wear out and leak as a result of time, use, and exposure to the environment.

How can I identify a tire leak?

Because a leak will cause the PSI to drop, a built-in tire pressure monitoring system, or TPMS, may warn you to lower pressure in one of your car’s tires. If your car lacks such technology, you may sense a difference in the ride quality when driving. When stopped, a visual inspection can reveal that the tire is losing air (or gas in the case of nitrogen-filled tires) and is beginning to flatten. However, the source of the slow leak must be identified before a repair can be carried out.

A pinhole in the tread or sidewall may be the reason for a gradual leak if a complete investigation of a leaky tire, which will most likely necessitate removal from the vehicle, does not reveal a nail or hole. However, the tire should not be the issue.

It’s possible that the air valve stem is leaking and needs to be changed, or that the tire bead (where it joins the wheel) isn’t correctly sealed to the rim (a common problem in areas where road salt is used which can attack the metal surface of the rim). Before repairing a slow leak, use soap and water, or just water, to find the cause. In a spray bottle, combine liquid soap and water and spray all sections of the tire tread, sidewalls, valve stem, and opening (with the cap removed) as well as along the rim on both sides with the soapy water until bubbles begin to form.

Another way to identify a tire leak

Remove the tire and wheel from the car and soak them in a tub of water to locate a leak. At the leak, bubbles form. Ride parts one at a time if the tub isn’t big enough to submerge the full tire.

Pinholes and minor holes in the tread can be plugged or repaired to prevent leaks. Large punctures are impossible to repair, and slight damage to the sidewalls or shoulders (the point where the tread and sidewall meet) usually necessitates a new tire purchase. Leaky valve stems and inserts (the tiny valve itself in the hose) can be replaced as well.

If the slow leak is caused by the wheel not being well seated on the tire, the leak can occasionally be stopped by removing the tire and applying a bead sealant.

How to fix a slow leak in your car tire?

It is vital that you have your tire diagnosed as soon as possible by a professionally qualified tire store or mobile tire repair service. In the event of a flat tire, a tire repair kit may be used to maintain the tire correctly inflated until it can be fixed. After that, the leak should be properly repaired with a tire repair kit that includes a hardened rubber shaft and a repair unit.

A professional tire technician can usually replace a damaged valve at a low cost if the leak is caused by a damaged valve. In some circumstances, though, the tire may need to be replaced. A tire technician may be able to reapply and reseal the tire using a bead sealer if the leak is caused by a damaged wheel. If the wheel is significantly broken, though, you may need to replace it yourself.
