Tire pressure is a crucial aspect of vehicle maintenance, and it’s often overlooked by many drivers. However, 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 distances, and even tire failure, which can result in accidents or costly repairs.
Why is Correct Tire Pressure Important?
Tire pressure affects the overall performance and safety of your vehicle in several ways:
Tire pressure affects the tire’s contact patch with the road, which in turn affects traction, braking, and cornering.
Underinflated tires can lead to reduced fuel efficiency, as the tire has to work harder to maintain speed.
Tire pressure affects the tire’s lifespan, as underinflated tires are more prone to wear and tear.
Proper tire pressure can also affect the vehicle’s handling and stability.
How to Check Your Tire Pressure?
Checking your tire pressure is a relatively simple process that can be done at home or at a tire shop:
To check your tire pressure, you’ll need a tire pressure gauge and your vehicle’s recommended tire pressure, which can be found:
In your vehicle’s owner’s manual.
On the tire information placard, which is usually located on the driver’s side doorjamb or inside the fuel filler door.
On the manufacturer’s website. (See Also: Who Sells Dextero Tires? Top Retailers Revealed)
Using a Tire Pressure Gauge
To use a tire pressure gauge, follow these steps:
Make sure the tire is cold, meaning the vehicle has been parked for at least three hours and has not been driven recently.
Remove the valve cap and press the tire pressure gauge onto the valve stem.
Take a reading of the pressure and compare it to the recommended pressure.
If the pressure is too low, add air as needed. If the pressure is too high, release air as needed.
How to Determine the Correct Tire Pressure?
The correct tire pressure is the pressure recommended by the vehicle manufacturer, which can be found as mentioned earlier. However, there are some general guidelines to follow:
For passenger vehicles, the recommended tire pressure is usually between 30-40 psi (pounds per square inch). For light trucks and SUVs, the recommended pressure is usually between 35-50 psi. For heavy-duty trucks and commercial vehicles, the recommended pressure is usually between 40-80 psi.
Factors That Affect Tire Pressure
There are several factors that can affect the correct tire pressure:
| Factor | Effect on Tire Pressure |
|---|---|
| Temperature | Tire pressure increases as temperature rises. |
| Altitude | Tire pressure decreases as altitude increases. |
| Tire Size | Tire pressure may vary depending on tire size. |
| Loading Conditions | Tire pressure may vary depending on the load being carried. |

It’s recommended to check your tire pressure at least once a month, and before long trips. You should also check your tire pressure after driving in extreme temperatures or at high altitudes.
Tips for Maintaining Proper Tire Pressure
Use a tire pressure gauge that is accurate and easy to read.
Check your tire pressure when the tires are cold, as driving can heat up the tires and affect the reading.
Use the same tire pressure gauge to check all four tires, to ensure consistency.
Keep a record of your tire pressure readings, to track any changes over time.
