A flat tire is an unpleasant experience that some of us have experienced a couple of times. While it is an unnerving situation, it is not the worst thing that’ll happen to your vehicle because all you may need is to inflate the tires. But what if it requires tracing and patching the leaking areas or replacing the tires? How long can a car sit on a flat tire?
The wheels are meant to carry the entire weight of the car. But to do this, the tires must be well inflated because the rims can damage the tires and tubes if the vehicle sits on deflated tires for more than twenty-four hours. We’ll throw more light on this in the following sections. But let’s start with why do tires go flat when a car sits?
What causes tires to flat while parked?
Tires, whether new or old, can go flat overnight. While this is not normal, it’s worth noting that it can happen to anyone. Here are probable reasons your car tire deflated overnight.
Proper tire sealing is important to retain the air or nitrogen for a long time. If the service technician does not seal the tires properly, it’ll cause them to leak air overnight, resulting in a flat tire the next morning. This happens to both new and old tires.
Faulty valve stem
The tire valve stems are used to inflate and deflate the tires. If the valve goes bad, it can cause air leaks. This is common with old tires. However, it can happen on new tires. New tires come with new valve stems, but there may be a manufacturing defect on the valve stem. A faulty valve stem will cause slow and steady air leaks, which could cause flat tires overnight.
Heat, especially during summer, causes the air pressure in your tires to rise. When this happens, it could lead to air leaks, potentially resulting in flat tires.
If the rim surface is corroded or defective, it’ll not ensure proper sealing between the tires and rims. If this is the case, the air pressure will leak slowly, invariably causing flat tires overnight.
The common cause of flat tires is a puncture. This is the most obvious cause, and it can happen anywhere – while driving or parking the vehicle in a parking slot. This usually happens when the tires run over nails, industrial staples, screws, or any sharp object.
If you’re wondering, how long does it take for a car to go flat with a nail in it? There’s no straightforward answer to this. It can take a few hours or months for your tire to go flat with a nail in it.
How to avoid tires to flat while parked
Fortunately, you can prevent or reduce the chances of having flat tires while parked. Here are the common ways to avoid flat tires overnight.
Maintain proper air pressure
Ensure your tires are properly inflated at all times. Do not over or underinflate your car tires. Keeping the tires below the recommended PSI can cause gradual air leaks.
On the other hand, running with overinflated tires in hot weather during the day will increase the air pressure. If this occurs, the tire can start leaking air slowly, even under normal temperatures. At first, you’ll not notice the leak, but it’ll become obvious the next morning.
Ensure there’s no valve stem leakage
When inflating your tires or going for tire rotation, wheel balancing, or alignment, ask the service technician to inspect the valve stem for leaks. If the stem is too old or dirty, have them replace it.
Ensure the tires are mounted properly
When installing new tires or working on old ones, ensure the service technician clean the rims properly. As explained above, a corroded or defective rim will disrupt the sealing between the rim and tires. Therefore, cleaning the rim and ensuring proper sealing will help prevent tires from getting flat overnight.
Watch your surroundings before parking.
By watching your surrounding before parking, you’ll see if there’s any sharp object on the way. If you run over a sharp object like nails, the tires will not blow out, but the air will escape slowly, leaving you with a flat tire the next morning.
Inspect for wear and tear
Some tire wear and tears are normal, but you can minimize the wear by avoiding automatic braking, skidding, and fast take-offs. In addition, inspecting the tires, and going for scheduled tire rotations, wheel balancing, and alignments will reduce tire wear.
The point of inspecting and minimizing tire wear is to extend the tire lifespan and prevent unnecessary air leaks, especially when parked overnight.
How Long can a car sit on a Flat Tire?
A car can sit on a flat tire as long as you let it. However, if you’re asking how long can a vehicle safely sit on a flat tire or can I leave my car parked with a flat tire? Do not leave your car to sit on a flat tire for more than twenty-four hours. If you let the vehicle sit longer, you stand the chance of damaging your rim, tube, and tires.
If you want the car to continue sitting for an extended period without causing any damage, lift the vehicle and support it with jack stands. If the flat tires sit any longer, it’ll cause tire bubbles, weak spots, deterioration, and it’ll cause erosion in that area.

Frequently Asked Questions (FAQs)
Q: Is it okay for a car to sit on a flat tire?
It’s okay to let a car sit on a flat tire for a while. In any case, do not let the car sit on a flat tire for more than twenty-four hours. Anything more than that increases the chances of tire, rim, and tube damage. Aside from sitting, do not drive with a flat tire. Driving with a flat tire will drastically decrease the wheel handling capacity and cause structural damage to the wheels, alignments, brakes system components, and other suspension system components.
Q: Can I drive 1 mile on a flat tire?
Do not drive with a flat tire because it will affect vehicle handling, increase the risk of damaging the tires, and cause structural damage. However, there are times it may be necessary to drive 1 mile or more with a flat tire. For instance, if the deflation is not much and there’s a gas station within the next one or two kilometers, you may have to drive to the gas station and add air to the tires.
Q: How do you move a car with a flat tire?
We do not recommend driving on a flat tire because it can cause structural damage and condemn the tires. However, sometimes you have no option but to move with it, at least for a short distance.
To drive a car with flat tires, you have to;
- Drive slowly – between 15 to 20 miles per hour
- Get out of the speed lane
- Drive on flat, smooth ground. Avoid broken patches of asphalts, portholes, and steep inclines.
- Drive as straight as possible
- Don’t go far. Find a nearby gas station or auto service center and fix the deflated tire.
Sometimes, having flat tires overnight is inevitable. However, you can minimize the chances of experiencing this annoying experience by watching your surroundings for sharp objects before parking and going for regular tire maintenance.
We’ve answered the question, how long can a car sit on a flat tire to help you take preventive measures and avoid causing damage to the tires, tubes, and rims. Do not let your car sit on a flat tire for more than a day.
