The tire went flat overnight but now holds air, this is a common problem faced by vehicles. Every vehicle owner must have faced this type of problem at one time or another.
Sometimes when we drive the vehicle, the air pressure in the tire remains constant, but when the vehicle is parked for a long time at night, you see this type of situation where the tire flat overnight but now holds air.
In this post, you will learn in detail about the problem of a tIre that went flat overnight but now holds air. Why does this problem happen? What to do when this happens?
Causes of A Tire Went Flat Overnight
In most cases, a damaged or worn tire valve can cause the tire to go flat overnight. Because of a faulty tire valve, there is a slow air leak. Other causes of a flat tire overnight include a faulty tire valve, a sharp nail or glass in the tire, or a bent rim of the tire.
1. Change in Temperature
Changes in weather and temperature can also cause fluctuations in the air pressure in a vehicle’s tyres.
If your vehicle is parked in cold weather and the weather temperature drops significantly overnight, this can cause the vehicle’s tire pressure to drop and cause a vehicle tire flat.
2. Puncture or Leak
Often, a puncture or leak in a vehicle’s tire can also result in a flat tire overnight. If there is a small puncture in the tyre, then gradually the tire will become flat. So if the puncture or leak is small, the tire may hold air for a while before it goes flat again.
If your vehicle’s tire is repeatedly going flat even after filling it with air, then the tire should be inspected by a professional and repaired if necessary.
3. Faulty Tire Valve Stem
In most cases, a bad tire valve stem can be the cause of a vehicle’s tire deflation overnight. The tire valve allows air to enter the tire and prevents the air pressure in the tire from leaking.
But sometimes the tire valve is loose or damaged, and then there is a slow leak of air from the tire, due to which the tire slowly starts deflating and the tire becomes flat.
4. Improperly Installed Tire Bead
In vehicles, the tire bead is the side of the tyre. The tire bead fits over the wheel rim. If the tire is not properly installed over the rim, the bead of the tire may not be seated properly, allowing air to escape and the tyre to slowly lose air pressure. However, if the tire bead is only slightly off, the tire may hold air for a short time before losing pressure again.
5. Bent Tire Rim
In many cases, the tire rim of a vehicle gets bent for one reason or another. Often during high speed of the vehicle, the tire rim gets bent due to a sudden fall of the tire in the pit or hitting something.
Due to this, air starts leaking slowly between the tire and the rim of the vehicle, and the tire becomes flat when the vehicle is parked overnight.
Is it Normal For Tires To Lose Air Overnight?
The rate at which vehicle tires lose air overnight depends on a number of different factors. Losing air from a worn vehicle tire can be a normal process.
Flattening of a vehicle’s tire depends on the age of the tyre, temperature changes, driving habits, and road conditions. But if your vehicle’s tires are new and still your vehicle’s tire is getting flat at night, then it can become a matter of concern.
Because the reason for the new tire being flat overnight could be a tire puncture, a big cut in the tire or the tire rim being bent, etc. In many cases, roads with sharp edges and strewn debris can damage even well-maintained tyres. So for this, one should investigate the reasons for the vehicle tire losing air.
What Can You Do To Prevent Tires Went Flat Overnight?
- You should regularly check the air pressure in all tires to prevent a flat tire.
- Check the tire rim; if the tire rim is warped in any way or has fine cracking, it should be repaired or replaced.
- Make sure that there are no pieces of glass or nails in the tire of the vehicle. Because it can cause the air to slowly leak out of the tyre.
- Avoid using excessively worn or weak tires
- Drive carefully on a road with stones and scattered debris.
- Take care of the rotation of the tires from time to time, as without rotation for a long time, air may leak out.
- The tire valve stem should be checked regularly, as a loose or worn tire valve stem can also cause air to leak out of the tire.
What Happens If You Drive With A Flat Tire?
If you drive your vehicle with worn or bad tires, it can be dangerous for your safety. Especially when you are driving the vehicle at high speed. Because a bad tire on your vehicle can get flat anytime during high speed.
Second, there is always the problem of air leakage from bad tires in your vehicle. Because fine cracks appear in overworn tires. Bad tires also hinder the control of the vehicle.
FAQ’s
Q. If a tire bursts, is it ruined?
If the tire is not inflated to support the weight of your vehicle or does not have enough air, it can lead to ‘tire damage’ and render the tire beyond repair.
Q. Can I drive 10 minutes on a flat tire?
If your vehicle’s tire is flat or punctured in an emergency, you can take the vehicle slowly to the tire puncture repair shop. But it is never recommended by the tire manufacturer to drive a vehicle with a flat tire. Doing so may cause additional damage to the tires and rims of your vehicle.
