Tire pressure is one of the most critical aspects of vehicle maintenance, and it’s often overlooked by many car owners. Proper tire pressure can significantly impact the safety, fuel efficiency, and overall performance of your vehicle. In fact, underinflated tires can lead to reduced traction, increased stopping distance, and even tire failure, which can result in accidents or costly repairs. On the other hand, properly inflated tires can improve fuel efficiency, reduce tire wear, and provide a smoother ride. With the importance of tire pressure in mind, it’s essential to know how to check tire pressure at a gas station.
Why Check Tire Pressure at a Gas Station?
Gas stations are convenient locations to check tire pressure, especially if you’re on the go or don’t have access to a tire pressure gauge at home. Many gas stations have air compressors and tire pressure gauges available for public use. Additionally, checking tire pressure at a gas station can help you identify any issues with your tires, such as leaks or uneven wear, which can be addressed promptly.
What You’ll Need
To check tire pressure at a gas station, you’ll need a few basic tools:
- A tire pressure gauge (if you don’t have one, you can purchase one at the gas station or online)
- A penny (for the penny test)
- A tire pressure chart or the owner’s manual for your vehicle (to determine the recommended tire pressure)
The Penny Test
The penny test is a simple way to check tire tread depth and identify any signs of uneven wear. To perform the test, place a penny in the tire groove with Lincoln’s head facing down. If you can see the top of Lincoln’s head, your tire tread is worn out and needs to be replaced. This test can help you identify any issues with your tires before they become a safety concern.

- Find the tire pressure gauge at the gas station and make sure it’s set to the correct unit of measurement (PSI or BAR)
- Remove the valve cap from the tire stem and press the tire pressure gauge onto the valve stem
- Hold the gauge firmly in place and take a reading of the current tire pressure
- Compare the reading to the recommended tire pressure, which can be found in the owner’s manual or on the tire information placard on the driver’s side doorjamb
- If the pressure is too low, add air to the tire using the air compressor at the gas station
- Recheck the tire pressure with the gauge to ensure it’s at the recommended level
Tire Pressure Chart
Here is a general tire pressure chart to help you determine the recommended tire pressure for your vehicle:
| Tire Size | Recommended Pressure (PSI) |
|---|---|
| 225/50R17 | 35-40 PSI |
| 235/50R18 | 35-40 PSI |
| 245/45R19 | 35-40 PSI |
| 255/40R20 | 35-40 PSI |
Common Tire Pressure Mistakes
Here are some common tire pressure mistakes to avoid:
- Not checking tire pressure regularly
- Using the wrong tire pressure gauge
- Not adjusting tire pressure for load changes (e.g., carrying heavy loads or towing a trailer)
- Not checking tire pressure when tires are cold (i.e., not driven recently)
Recap
Checking tire pressure at a gas station is a simple and essential part of vehicle maintenance. By following the steps outlined in this article, you can ensure your tires are properly inflated and ready for the road. Remember to check your tire pressure regularly, use the correct gauge, and adjust for load changes. With proper tire pressure, you can improve fuel efficiency, reduce tire wear, and enhance overall vehicle performance.
