Why the Correct Tire Pressure Matters

You probably hear about car tire pressure every time you visit an auto shop. But what is it, and why does it matter?

Tire pressure is a crucial factor in the roadworthiness of your car. Failure to meet tire pressure requirements will increase your risk of accidents and injuries.

Here are the main reasons why correct tire pressure matters:


Tires with incorrect air pressure will expose both the driver and passengers to road risks.

When a tire is underinflated, it becomes prone to punctures. And since the tire isn’t stiff enough, your brakes won’t bite well.

On the other hand, overinflated tires are also dangerous due to the risk of blowing out. High-speed blow-outs are the most dangerous as it will be impossible to control your car.

Ideal fuel economy

Underinflated tires mean that the rubber will have more footprint. This increased road contact translates to higher friction.

And since there’s higher friction, the car’s engine will have to work harder. The result is higher fuel consumption and more engine wear and tear.

It’s like riding a bicycle with a flat tire. Your legs would have to compensate, and you’ll exert more energy in the process.

Longer tire lifespan

The correct pressure prevents unnecessary wear and tear on your car’s tires. This will prevent premature thinning of the treads and other friction-related damages.

Similar to the first point, increased contact with the ground will cause more damage to the tires. You’ll soon need a new set of tires faster than normal.

Inspecting your tires

By checking your tire’s pressure, you also get the chance to inspect for damages. This will let you notice issues like thin treads, cracks, uneven thinning, and so on.

Identifying these problems early will spare you from accidents later on. Also, it will let you mitigate the problem before it damages your tires for good.

How to know if your tires have the right pressure

Each car has a recommended tire pressure. On newer models, there would be a sticker by the driver’s door where the ideal tire pressure is indicated.

Generally, most passenger car tires would be rated for 32 to 35 psi in a cold environment. However, adjustments will be necessary during summer as the heat can cause tire material to expand. Nevertheless, an increased reading by 2 to 6 psi is considered normal on a hot day.

If you’re going to tow or transport a heavy load, you may need to increase your tire pressure. This is to compensate for the added weight.

To check if your tires have the right pressure, you should purchase a digital tire gauge. You have to press the gauge slot into the tire’s air valve for quick reading.

Depending on the reading, you may need to add or reduce air. If it’s within the recommended pressure, your car is safe and ready for driving.


Keeping the correct tire pressure is a matter of road safety. It will also prevent unnecessary wear and tear on your vehicle.

The good news is that car tire pressure is very easy to check. You only need a digital pressure gauge to see if your wheels are over or under inflated.
