How to Check Tire Pressure: A Step-by-Step Guide

Tire pressure plays a key role in both vehicle safety and performance. Overall, proper tire pressure helps your car’s handling, improves fuel efficiency, and extends the life of your tires. With changes in temperature, your tire pressure can fluctuate, which is why it’s important to check it regularly.

In this guide, we’ll walk you through why tire pressure matters, how to check it, and what steps you can take to make sure your tires are always properly inflated.

Why Tire Pressure Matters

Driving with the right tire pressure isn’t just about comfort. It’s about safety. Underinflated tires can cause poor handling, increased tire wear, and reduced fuel economy. In contrast, overinflated tires can create a harsh ride and uneven tread wear. Both conditions increase your risk of a blowout.

Since tire pressure can change with the temperature, regular checks are essential, especially during seasonal changes. For example, tire pressure drops about 1 PSI for every 5–6°C change in outside temperature.

Where to Find Your Recommended Tire Pressure

Before you start checking your tire pressure, you need to know what the correct number should be for your vehicle. You can find your recommended tire pressure in two places:

• The driver’s side door sticker – Open your driver’s side door and look for a sticker on the door frame. This will list the manufacturer’s recommended tire pressure (measured in PSI).
• Your owner’s manual – If you can’t find the sticker, the owner’s manual will have the tire pressure information you need.

How to Check Tire Pressure: Step-by-Step

Checking your tire pressure is quick and easy. Here’s how:

• Get a tire pressure gauge – You can find inexpensive gauges at auto parts stores, gas stations, or even online. In fact, you can even get digital ones that are very easy to read.
• Check when tires are cold – Tire pressure readings are most accurate when the tires haven’t been driven for at least three hours. Heat from driving can temporarily raise pressure.
• Locate the valve stem – This is the small cap on the side of your tire. Remove the cap and keep it somewhere safe.
• Press the gauge onto the valve – Firmly press the gauge onto the valve stem. You’ll hear a quick hiss of air, then the gauge will give you a reading in PSI.
• Compare with recommended pressure – Check the number against the recommended PSI from your door sticker or owner’s manual.
• Adjust if necessary – If the tire pressure is too low, add air at a gas station or with a home air compressor. If it’s too high, release some air by pressing the small pin inside the valve.
• Replace the valve cap – Don’t forget to screw the cap back on when you’re done.
• Repeat these steps for all four tires.

How Often Should You Check Tire Pressure?

We recommend checking your tire pressure at least once a month and before any long road trip. During extreme weather changes, such as the transition from summer to winter, you may want to check even more often. You can bring your vehicle into your local Trail Tire, and we’ll be happy to do a tire pressure check.

Final Thoughts

Maintaining proper tire pressure is a simple habit that can save you money, improve your driving experience, and keep you safe on the road. Therefore, by checking your tire pressure regularly and adjusting it as needed, you’ll extend the life of your tires and reduce your risk of accidents caused by underinflated or overinflated tires.
