Tire Pressure 101: How to Check, Inflate, and Maintain Proper Tire Pressure

According to a survey, only 42.2 percent of motorists express confidence in their ability to change a flat tire, while a startling 20 percent admit they wouldn’t know where to begin when faced with this roadside emergency. Proper tire pressure is crucial for avoiding flats and ensuring your safety on the road. In this comprehensive guide, we’ll walk you through the essentials of tire pressure maintenance. If you ever have a flat tire in the Raleigh area, remember that Straight-Away Towing Service is just a call away at (919) 234-5400.

Understanding Tire Pressure

Tire pressure is the amount of air inside your tires, measured in pounds per square inch (PSI). Every vehicle has a recommended tire pressure, which you can find in your owner’s manual or on a sticker inside the driver’s side door jamb.

Factors like load and speed can affect the recommended tire pressure. Driving with underinflated tires can lead to poor handling, decreased fuel efficiency, and increased wear. Overinflated tires can make your ride less comfortable and more susceptible to damage from potholes and other road hazards.

The Dangers of Improper Tire Pressure

Neglecting your tire pressure can have serious consequences. Underinflated tires can cause:

• Decreased fuel efficiency (up to 3% reduction)
• Increased tire wear, especially on the edges
• Reduced handling and stability
• Increased risk of tire failure or blowouts

On the other hand, overinflated tires can lead to:

• A harsher, less comfortable ride
• Reduced traction, especially in wet conditions
• Increased wear on the center of the tire tread
• Higher risk of damage from potholes and road debris

Checking Tire Pressure

Check your tire pressure at least once a month, before long trips, and when the seasons change. You’ll need a reliable tire pressure gauge, which comes in digital or analog styles.

To check your tire pressure:

1. Make sure your tires are cold (haven’t been driven on for at least 3 hours).
2. Remove the valve cap and press the gauge firmly onto the valve stem.
3. Read the pressure and compare it to the recommended PSI.
4. Replace the valve cap and record the pressure for each tire.

Tips for Accurate Tire Pressure Readings

• Always check your tire pressure when the tires are cold. Driving heats up the air inside the tires, which can give you an inaccurate reading.
• Check your tire pressure at least once a month, even if your vehicle has a tire pressure monitoring system (TPMS). These systems are designed to alert you when your tire pressure is significantly low, but it’s still important to catch any issues early.
• Invest in a high-quality tire pressure gauge. Cheap or poorly-maintained gauges can give inconsistent or inaccurate readings.

Inflating Tires

If your tires are underinflated, you’ll need an air compressor or a tire inflator to add air. Many gas stations have coin-operated air compressors, or you can purchase a portable one for home use.

To inflate your tires:

1. Set the desired PSI on the inflator or compressor.
2. Attach the hose to the valve stem and add air in short bursts.
3. Recheck the pressure with your gauge and adjust as needed.

Inflation Tips and Tricks

• If you’re using a coin-operated air compressor at a gas station, bring plenty of change. Some machines can be finicky, and you don’t want to run out of time before your tires are properly inflated.
• Don’t rely on the gauge built into the air compressor. These gauges can be inaccurate due to wear and tear. Always double-check the pressure with your own gauge.
• If you’re inflating your tires at home, consider investing in a high-quality air compressor. Look for one with a built-in pressure gauge and an automatic shut-off feature to prevent overinflation.

Maintaining Proper Tire Pressure

Keeping your tires properly inflated offers several benefits:

• Improved safety and handling
• Better fuel efficiency (up to 3% savings)
• Longer tire life

To maintain proper tire pressure:

• Check and adjust pressure regularly
• Monitor tires for uneven wear or damage
• Rotate tires every 5,000-7,500 miles
• Don’t forget to keep your spare tire inflated

Speaking of spare tires, car buyers might be surprised to learn that only about 10 percent of new vehicles rolling off the assembly line include a full-size spare tire. Approximately 60 percent are equipped with a space-saving temporary spare, and the remaining models feature sealant kits, run-flat tire technology, or no dedicated flat tire solution whatsoever.

The Importance of Tire Rotation

Rotating your tires regularly helps ensure even wear and prolongs the life of your tires. Front and rear tires wear differently due to factors like weight distribution, steering, and acceleration. By rotating your tires every 5,000-7,500 miles, you can help all four tires wear at a similar rate.

There are several tire rotation patterns, depending on your vehicle’s drivetrain (front-wheel, rear-wheel, or all-wheel drive) and the type of tires you have (directional or non-directional). Consult your owner’s manual or a trusted mechanic to determine the best rotation pattern for your vehicle.

When to Seek Professional Help

If you notice any signs of tire damage, like bulges, blisters, or cuts, it’s time to have a professional take a look. If you’re unsure about your ability to properly check or inflate your tires, don’t hesitate to visit a professional. Many tire shops and service centers offer free tire pressure checks and inflation. They can also help you determine if your tires need to be replaced or repaired.

Conclusion

Proper tire pressure is essential for your safety and the longevity of your tires. By regularly checking and maintaining your tire pressure, you can avoid flats and other tire-related issues. Remember to keep an eye out for signs of wear or damage, and don’t forget to rotate your tires regularly.
