Proper tire inflation is crucial for safe and efficient driving. It affects your vehicle’s handling, braking performance, fuel economy, and tire lifespan. Knowing when and how to fill your tires with air can make a significant difference in your overall driving experience.

When to Fill Tires with Air
Regularly checking and maintaining your tire pressure is essential. Here’s a breakdown of when you should be filling your tires with air:
1. Before Long Trips
Before embarking on a long journey, it’s vital to ensure your tires are properly inflated. Underinflated tires can overheat and potentially blow out during extended driving, compromising safety.
2. Monthly Checks
Make it a habit to check your tire pressure at least once a month, even if you’re not planning a long trip. Tire pressure naturally fluctuates with temperature changes, and regular checks help you catch any gradual deflation.
3. After a Temperature Change
Significant temperature swings, both hot and cold, can impact tire pressure. If you’ve driven in extreme temperatures, check your tire pressure as soon as possible.
4. When You Notice Changes in Handling
If you experience any unusual handling, such as pulling to one side or a feeling of instability, it could be a sign of uneven tire pressure. Check your tires immediately and adjust as needed.
5. After Hitting a Pothole or Curb
A sudden impact can damage a tire and lead to air loss. Inspect your tires carefully after hitting a pothole or curb and inflate them if necessary.
When To Fill Tires With Air
Maintaining the correct tire pressure is crucial for safe and efficient driving. Under-inflated tires can lead to a number of problems, including reduced fuel efficiency, increased braking distance, and even tire blowouts. Over-inflated tires, on the other hand, can result in a harsh ride, reduced traction, and increased wear on the tire’s center tread. (See Also: Is It Safe To Remove Studs From Tires)
Understanding Tire Pressure
Tire pressure is measured in pounds per square inch (PSI). The recommended tire pressure for your vehicle can be found in the owner’s manual, on a sticker inside the driver’s side door jamb, or on a placard located on the vehicle itself. It’s important to note that the recommended pressure is usually specified for cold tires, meaning tires that have not been driven for at least three hours.
Factors Affecting Tire Pressure
Several factors can affect tire pressure, including:
- Temperature: As temperatures rise, tire pressure increases. Conversely, as temperatures drop, tire pressure decreases.
- Driving Conditions: Driving on rough roads or carrying heavy loads can also affect tire pressure.
- Age: Over time, tires naturally lose pressure due to air seeping through the rubber.
When to Check Tire Pressure
It’s a good idea to check your tire pressure at least once a month, and more frequently if you drive in extreme temperatures or conditions. You should also check your tire pressure before long trips and after hitting potholes or curbs.
Using a Tire Pressure Gauge
To check your tire pressure, you’ll need a tire pressure gauge. These are available at most gas stations and auto parts stores.
- Remove the valve stem cap from the tire.
- Press the tire pressure gauge firmly onto the valve stem.
- Read the pressure displayed on the gauge.
- Replace the valve stem cap.
When to Fill Tires With Air
You should fill your tires with air when the pressure is below the recommended level.
Signs of Under-Inflation
Here are some signs that your tires may be under-inflated:
- The tire appears to be bulging at the sides.
- The vehicle handles poorly, especially in corners.
- You hear a humming or roaring noise from the tires.
- The fuel economy is lower than usual.
- The tire pressure warning light on the dashboard is illuminated.
Adding Air to Tires
Most gas stations have air pumps that you can use to fill your tires. (See Also: How To Tell If You Need New Tires)
- Locate the air pump and insert your payment.
- Remove the valve stem cap from the tire.
- Connect the air hose to the valve stem.
- Set the desired pressure on the air pump.
- Depress the lever to release air into the tire.
- Monitor the pressure gauge on the air pump and stop adding air when the desired pressure is reached.
- Disconnect the air hose and replace the valve stem cap.
Important Considerations
Here are some important considerations when filling your tires with air:
Over-Inflation
Over-inflating your tires can be just as dangerous as under-inflating them. Over-inflated tires can lead to a harsher ride, reduced traction, and increased wear on the tire’s center tread.
Using Nitrogen
Nitrogen is a more stable gas than air, which means it doesn’t fluctuate as much with temperature changes. Using nitrogen in your tires can help to maintain consistent tire pressure and improve fuel economy. However, nitrogen is more expensive than air and may not be readily available at all gas stations.
Professional Tire Service
If you’re unsure about how to check or fill your tire pressure, it’s always best to consult a professional tire service technician. They can check your tire pressure, identify any potential problems, and provide you with expert advice on how to maintain your tires properly.
Recap
Maintaining the correct tire pressure is essential for safe and efficient driving. You should check your tire pressure at least once a month and fill them with air when the pressure is below the recommended level. Be aware of the signs of under-inflation and over-inflation, and consider using nitrogen if you want to improve tire pressure stability. If you have any questions or concerns, don’t hesitate to consult a professional tire service technician.

How often should I check my tire pressure?
It’s a good idea to check your tire pressure at least once a month, and before any long trips. You should also check your pressure when your tires are cold, meaning they haven’t been driven on for at least three hours. (See Also: Will Valvoline Put Air In Tires)
What happens if my tires are underinflated?
Underinflated tires can lead to decreased fuel efficiency, uneven tire wear, and a higher risk of blowouts. They can also affect your vehicle’s handling and braking performance.
What happens if my tires are overinflated?
Overinflated tires can make your ride feel harsh and bumpy. They can also increase the risk of a tire blowout, especially on rough roads. Overinflation also reduces the tire’s contact patch with the road, which can affect handling and braking.
What is the recommended tire pressure for my vehicle?
The recommended tire pressure for your vehicle can be found in your owner’s manual, on a sticker inside the driver’s side doorjamb, or on a placard on the tire itself.
How do I know if my tires need air?
A simple way to check if your tires need air is to look for a visual indication of low pressure, such as a tire that appears flattened or deflated. You can also use a tire pressure gauge to measure the pressure in each tire.
