Yes, hitting a pothole can absolutely cause a tire to lose air, ranging from a slow leak to a rapid deflation, by damaging the tire's sidewall, puncturing the tread, or breaking the seal between the tire and the wheel rim, potentially damaging the rim itself. This can happen immediately or develop into a slow leak, sometimes too slow for the Tire Pressure Monitoring System (TPMS) to catch, requiring a physical inspection.
But the damage may not stop there; the rim, or more commonly known as the wheel, is also at risk. In severe impacts with a pothole, the rim can get bent or the metal can crack, leading to air loss and sometimes even a hazardous tire blowout.
Bent or damaged rims can cause air to escape, especially if they no longer allow the tire to sit flush. This can happen from hitting a pothole, curb, or speed bump too hard.
One of the most common reasons why a tire keeps losing air with no hole is temperature fluctuations. As temperatures drop, the air inside your tires contracts, which causes a drop in pressure. For every 10-degree Fahrenheit drop in temperature, you can expect a loss of about 1-2 psi in your tires.
Potholes have caused many flat tires, tire damage, weakened belts and cords, and uneven tire wear.
Large potholes can damage your car's undercarriage. Exhaust pipes are among the components most likely to be damaged by potholes. Deep potholes can scrape or puncture pipes, causing leaks and increased emissions. In an impact, your vehicle's bumper absorbs the shock.
The "3% tire rule" is a guideline for replacing tires, stating that the new tire's overall diameter should not vary more than ±3% from the original to maintain speedometer accuracy, proper handling, and function of safety systems like ABS and traction control. Going outside this range can cause speedometer errors, clearance issues, and strain on the engine and transmission, while a separate (and false) "3-tire rule" rumor suggests insurance won't cover vandalism if only three tires are damaged.
Yes, tires can deflate without a puncture due to factors like temperature changes, valve problems, rim damage, or slow leaks in the tire itself. These issues may not always be visible on the tire's surface but can lead to gradual pressure loss.
If you find that your tire pressure is consistently low, it may be due to a faulty valve stem. Check the valve area for signs of hissing or bubbles when you apply soapy water to the valve. Rubber valve stems are prone to cracking and dry rot, especially if your vehicle is exposed to the elements regularly.
Remove the valve core on the wheel where the tire loses air slowly by inserting the removal tool tip into the stem and rotating it counterclockwise. If you see signs of corrosion, make sure to clean the stem before installing a new core. Screw a new core in place and pump the tire up.
It could be dangerous to drive when a tire has a slow leak, but sometimes it can't be helped. If you must go in such a situation, keep the speed down as much as possible and stay off highways. If the tire pressure gets too low, you could have a blowout.
As the air inside your tires heats up or cools down, it expands and contracts. This is especially noticeable during seasonal shifts or when you park your car outside overnight. For every 10-degree drop in temperature, tire pressure can decrease by about 1-2 psi.
After hitting a pothole, if it's safe to do so, pull over and inspect your vehicle. Look for obvious signs of damage, such as a flat tire or leaking fluids. If your vehicle is still drivable, proceed with caution, but if you notice any serious issues, it's best to stop driving and call for assistance.
When a car hits a pothole, you risk damaging your car's tyres, suspension, subframe or even throwing off your car's wheel alignment. This is why, it's important to report a pothole to the local council, so that they can fix the pothole and avoid damage to any other cars.
Signs of pothole damage
Pulling to one side and uneven tire wear – signs of alignment problems. Blisters or bulges on tire sidewalls or dents in the wheel rim – symptoms of tire damage. You risk a potentially disastrous tire blowout if don't have this taken care of.
Replacing a standard tyre valve is quick, easy, and affordable. In the UK: Garage/installation cost: around £10 per tyre – usually included in the price of a tyre replacement.
Signs & Symptoms of Bad Tires – When to Replace Them
A tire valve stem replacement can cost around $10 and is generally considered an easy task. But if you're thinking about bringing your vehicle to an auto repair shop to get the job done, you might need to shell out a couple more bucks.
The "3% tire rule" is a guideline for replacing tires, stating that the new tire's overall diameter should not vary more than ±3% from the original to maintain speedometer accuracy, proper handling, and function of safety systems like ABS and traction control.

Most materials are porous to some degree, and rubber certainly is. In other words, air slowly escapes directly through the tyre itself - no puncture is required. The rate of osmosis depends upon the construction of the tyre (especially its inner liner) but can be as high as 3 psi per month.
You don't know the depth of your tyre tread? Use the 25 cent trick! Insert a 25 cent piece into the tire's grooves with the nose of the caribou facing downward. If the caribou's nose isn't visible, it means the depth is superior to 6/32 of an inch.
There's a popular rumor known as the “three-tire rule”—that if only three of your four tires are slashed, insurance won't cover it. This is just not true— vandalism is vandalism.
The Rule of 105 states that the rim must be at least 105% the width of the tire if you have any chance of re-capturing airflow from the tire and controlling it or smoothing it. One of the most interesting aspects of the Rule of 105 is that before 2001, nobody was tunnel testing with 21 or 23mm tires.
