Tire losing air no leak found will be a nightmare for drivers. Most people have experienced a tire going flat unexpectedly, usually due to a nail hole.
However, some other users are upset by the tire that gradually goes flat for virtually no reason.
Tires lose air for various reasons, including loose valve stems, nails puncturing the tire or a sharp item, rocks creating a bead leak, a corroded wheel, or even inadequate repair of tire damage.
Slow tire leaks can sometimes happen, so you should know all possible causes.
Why Is My Tire Losing Air No Leak Found?
If your car’s tire keeps losing air but no hole, it might be because of a loose valve stem, missing valve cap, broken or bent wheel, damaged tire bead, or a nail/sharp object stuck in the tire.
Loose Or Poor Valve Stems
The first reason for a tire losing pressure but no leak is poor valve stems. Due to age or dirt, the valve stem and the interior may slowly start leaking.
The rubber stem might decay and split, causing air to leak slowly. Valve cores may not fit correctly in the valve stem because tiny dust particles make air escape.
Visibly Damaged Or Bent Wheel
Hitting a deep pothole or a curb too hard can damage the wheel rim, causing the tire rim to match the steel rim inaccurately.
Furthermore, the contact may have destroyed the tire-to-rim seal, allowing air to gradually drain away. The sidewall of the tire might also be harmed.
Tires Bead Damage
The tire bead is the tire’s side that sits on the rim.
As an inadequate rim sealer is installed, the tire bead is broken, or the rim is distorted, air will leak from the place of the tire bead seat. A bead leak is known as a low tire leak.
Hole In The Tire Sidewall
A hole in the tire’s sidewall may occur. It is frequently caused by contact with a foreign item, such as a stone or curb.
Check for abrasions on the tire’s sidewall, especially after impacting a curb, and use soapy water to check for air leaks.
Sharp Object Or Nail In The Tire
Sharp things like screws, nails and pointed stones can pierce a tire and then seal it. A very slow leak is a possible result.
Although the tire does not go flat right away, the leak is frequently considerable, leading the tire to be flat overnight or after some hours.
Tire Damage Caused By a Road Hazard
Uneven roads, road debris, and potholes may all result in significant harm to the tires and the car’s structure, including alignment, tire balance, and axles.
A pothole, for example, might break the rim and create a gradual leak.
Hole In The Thread
Another possible cause of tire leaking air no hole is overinflation. It can leave a pinhole leak in a tire tread or thread. Tires, on the other hand, heat up when driven at fast speeds.
The pressure in the tire rises as the temperature increases. As a result, air may go out via pinholes, or the tire may explode.
Corroded Wheel Causing a Bead Leak
Steel tire rims rust over time, particularly when exposed to salt during the winter.
Rust on the rim can result in a weak seal, causing air to leak and tire pressure to gradually drop. To fix the problem, drivers will need to purchase new rims.
Bad Repair Job Or Poor Seal
When a tire is replaced, the tire technician scrapes the rim with a brush to clean rust and debris. In addition, the rim is covered in tire sealant to aid in sealing the tire bead to the rim.
Plugs are used to fill holes left by nails. If one of these duties is not carried out properly, air might gradually escape, resulting in a flat tire or low air pressure.
Missing Valve Cap
Tire losing air no leak found can also stem from a missing valve cap. The valve caps shield the tire valves and stem from dirt and other particles.
Dust may get into the valve stem, leading to a poor fit between the stem and the tire valve and making air go outside. A valve cap can help protect the valve.
How To Fix the Tire Pressure Leak Issues?
Repairing a Tire
A puncture can be repaired in a technician’s tire shop or at home. Use tire sealants or a specific plug kit if you wish to do it yourself. A sealant, an air pump, and a pressure gauge are required.
Insert the sealant’s nose into the puncture where the tire slowly loses air or into the valve. Pour it gently until you’ve used up the entire regular spray bottle.
It will act as a protective barrier within the tire, allowing the pressure to drive the mixture into the hole when you pump it up. So, it will create a plug and fix your tire, even tire leaking air but no hole.
Besides, there is another way to patch a tire that you might need to do more work. It is using a plug kit. You can read the attached manual to learn how to use the plug kit.
Repairing The Bad Valve Stem
A valve removal tool and a replacement tire valve core are what you need. If you want to do it more simply, you may need a lug wrench and a vehicle jack to get the wheel out.
Put the removal tool tip into the stem and rotate it to detach the tire valve core where there is tire deflating slowly.
If you notice rust, wipe the stem before inserting a new core. Install a new core and inflate the tire.
Repairing And Restoring The Rim
When you get a damaged wheel, you should take it to a mechanic who provides hydraulic help. It is the most current and effective method of straightening a wheel.
You may help prevent it by cleaning the wheels yourself. Rust is one main reason for slow air leaks.
You will have to take the wheel and tire out of the car. You will also need aluminum metallic polish, sanding tools, and wax.
Maintaining Proper Inflation
Regularly Inspect
Inspect the pressure of your tires every week to see if any tire is losing air faster than others.
When It Is Cold, Check
Examine the tires while they are cold. It is unnecessary to wait too long for the tires to chill down – 2 hours is enough.
Before you inspect the pressure, ensure the automobile has been in the shade.
Remove 2 psi if the car was in the sun or you’ve driven for more than 15 minutes to check the actual rate of inflation.
Use a Pressure Gauge That Has Been Calibrated
Because a tire keeps leaking air gradually, every psi loss is significant. Even a new gauge may display +/- 3 psi, which is a considerable difference for passenger vehicles.
Conclusion
Tire losing air no leak found is troublesome. In some cases, you will need to change the rim or even the whole wheel system.
If you don’t want to spend much time and money on a tire technician, you can read the possible reasons above. You can try fixing it yourself, but be careful with the pressure.
After all your efforts and the problem remains, you should take it to a mechanic for a thorough inspection.
