One of the reasons it’s crucial to understand how and when to check your tire pressure is that underinflated tires may wear out prematurely. Tires having the wrong pressure can reduce gas mileage and have a negative effect on how your car handles. On a label inside the driver’s door, you can normally find the appropriate tire pressure for your car.
The owner’s manual will typically also list it. Psi, or pounds per square inch, is a unit of tire pressure measurement. You should also note that the tire pressure is listed on the sidewall. The recommended tire pressure for your car can be found on the door sticker or owner’s handbook, so stick with their recommendations.
Well, in this article, I’ll be walking you through how you can check the tire pressure in your car. Nevertheless, the answers to the following questions will be discussed:
- Why is it important to maintain proper tire pressure?
- How often should I check my tire pressure?
- Can I check my tire pressure without a gauge?
So, let’s dive in!

Why is it important to maintain proper tire pressure?
Maintaining proper tire pressure ensures that your tires will last longer. It is quite easy to maintain correct tire inflation, which is crucial for your car’s tires to function well overall. In comparison to a poorly inflated tire, a properly inflated tire offers a longer life, quicker steering response, improved fuel efficiency, and a smoother ride.
Both under and over-inflation can result in problems such as early tread deterioration and potential tire failure. Checking your tire pressure once a month is the best method to make sure you’re getting the most out of your tires.
How often should I check my tire pressure?
Check all four of your tires, including your spare, at least once a month and during significant temperature changes because your tires lose one to two PSI per month after you fill them. This rule of thumb holds true whether you have nitrogen-inflated tires, a tire pressure monitoring system (TPMS) on your car, or none of the above. Although cars can alert you when your tires need air, you shouldn’t solely rely on that technology. Proactive tire repair and upkeep is the recommended course of action.
Can I check my tire pressure without a gauge?
Yes, you can check your tire pressure without a gauge. To check the pressure in your tire, use your thumb. The pressure can easily be felt by pressing your hand down on the tire. Tires with low pressure will be flexible. Your tires will feel very stiff if they are over-inflated. If your tire is neither too soft nor too stiff as described above, your tire pressure is appropriate.
How to check tire pressure?
You will require a tire pressure gauge, which is available at the majority of gas stations and auto parts retailers. Also, you should check the tire pressure when it is cold since as you drive, friction heats up the tires and impacts the pressure. If you’ve already driven the car, it’s advised to wait at least three hours for the tires to cool down before checking them. Otherwise, check them first thing in the morning.
Here’s how to check tire pressure with a gauge:
- Begin with cold tires.
- Consult the manufacturer for the correct psi.
- Note the psi for each tire.
- Check tire pressure with the gauge on hand.
- Fill up to the recommended psi if needed.
- Carry out the process monthly for maintenance purposes.

Begin with cold tires:
Manufacturers of automobiles define PSI, or “pounds per square inch,” of tire pressure, with the assumption that the tires are cold. After three hours or more of parking or after less than a mile (1.6 km) of moderately rapid driving, tires are deemed to be cold. Your pressure gauge measures in PSI and gives readings in that unit.
Consult the manufacturer for the correct psi:
To get the suggested cold tire PSI for your front and rear tires, check the driver’s side door jamb or your owner’s handbook. Consult your car’s dealer, the manufacturer, or a certified tire expert if you can’t find it.
Note the psi for each tire:
To minimize confusion as you travel around your car monitoring tire pressure, write down the proper PSI for each if your front and rear tires need different pressure levels.
Check tire pressure with the gauge on hand:
Take off one of your tires’ valve caps. After that, set the pressure gauge on the valve stem and apply sufficient pressure so that the hissing sound stops and your gauge gives a reading. With a typical gauge, air pressure will cause a little bar to emerge from the gauge’s base. The bar has measurement units carved into it. You can view the reading on a screen with a digital gauge. Repeat this step for each of the four tires, writing down the readings.
Fill up to the recommended psi if needed:
Refill any low-pressure tires using an air compressor. Since many air compressors differ from one another, attentively reading the instructions can help you use them properly. To ensure that the hose can reach all four tires while using an air compressor at a petrol station, park carefully.
Till you hear the motor going, put change into the machine. By positioning the hose end over the valve stem and pulling the lever, you may fill each tire. Your tires may be “hot” if you use an air compressor from a gas station. When tires need to have their inflation pressure adjusted while they are “hot,” increase it by 4 psi (14 kPa) from the suggested cold inflation value.
When the tires are cool, check the inflation pressure once more. Utilize the gauge to recheck tire pressure after filling them. You can always let some air back out if you overinflated the tires at this stage. Never drive with tires that are too inflated. Increased pressure can lead to less traction, premature wear, and reduced impact absorption.
Carry out the process monthly for maintenance purposes:
Make the previous process a recurring monthly ritual. The easiest approach to make sure your tires never fall significantly below the ideal PSI is to regularly check your tire pressure.
Here’s how to check tire pressure without a gauge:
Psi Check
Your tire’s air pressure is measured in pound-forces-per-square-inch. It informs you of the maximum inflation pressure your tire can handle. This information is typically found in the driver’s manual. It might also be seen on the doors on the driver’s side. The number typically denotes the minimum pound-force per square inch that the tire should be filled to.
However, you are free to change it as you see fit. For proper operation, greater pressure is required the more the vehicle can transport. The recommended PSI for small vehicles like sedans and minivans ranges from 27 to 32. But if necessary, the tires can travel 40 miles.
Because their tires require more inflation pressure to support the vehicle’s weight effectively, SUVs and trucks typically have a PSI of 45 or higher. You should be aware that some pickup truck models have differing PSI ratings for the front and rear tires. To be certain, consult your handbook.
Mass Over Wheels
This approach is based on measuring the tire deformity after adding weight to the tires. You should put weight on the tires to determine the degree of tire deformation. Low tire pressure causes a 10% to 15% change in tire deformation. You need a little bit more air in your tires if you see that much of a change. Check the tires gently as you apply pressure to make sure they don’t get incredibly rigid.
Trail Comparison
You need a flat surfaced road or pavement for this procedure. You must label your tires with ink or another marking material. After that, drive the car a little to leave a mark on the road. Watch the path your tires left behind after the drive. There are some variations that can be seen by comparing the trail. When compared to other tires, low-pressure tires frequently leave a streak. Repeat the test while adding a bit more air to the underinflated tires until moderate pressure is obtained.
Cargo
The cargo test is functional. Consider packing the car with cargo to see if the tires might become bogged down. Logically, any low-pressure tire on your car will be weighed down by cargo. You have low-pressure tires that require extra air pressure if you observe that one side of the automobile carries the cargo load more heavily than the other.
To level out the weight distribution, locate the tires that are underinflated and apply more air to them. But make sure that when you remove the load, you check and restore the tires’ Pound-force Per Square Inch (PSI) to normal by adding sufficient air pressure.
Hand Pressure
Push your palm against the tire to feel the pressure in order to check the tire pressure with your hand. While overinflated tires are extremely stiff, low-pressure tires are often soft and cushiony. Add more air to the tire if it seems squishy. As you progressively add air, gradually check the pressure with your hand. If your tire’s air pressure is too high, squeeze the air nozzle’s stem until you can push the tire just a little bit.
Eye Observation
You must first park your automobile on a level surface in order to use this technique to check your tire pressure. Check the tires of your car from both sides after you’ve parked it. What you’re searching for is a bulge, which is a spherical swelling coming from one of the tire’s sides. Your tire pressure is low if there is a bulge of more than ten millimeters on either side. Before driving, you might need to pump the tires. Tires should be inflated until they are firm but not painfully so.

FAQs
How do I know if my tires need pressure?
To feel the pressure, simply press your thumb down on the tire. Tires with low pressure will be pliable. If your tires are overinflated, you will notice that they are quite stiff. If your tire is neither too soft nor too stiff as described above, your tire pressure is appropriate.
How do you check tire pressure at a petrol station?
What is the normal tire pressure?
Around 30 to 35 psi
The psi requirement for the majority of passenger cars will be between 30 and 35 psi, however, a number of vehicles fall outside of that range and each vehicle will have unique requirements. A smooth ride, evenly distributed tire wear, and improved fuel economy are all benefits of proper tire inflation.
How much air do I put in my tires?
30-35 PSI
The recommended tire pressure for the majority of passenger cars is between 30-35 PSI. To make sure that your car’s tires are inflated to the correct pressure, check their pressure frequently. If not, it will negatively impact tire life, vehicle performance, and how frequently you need to replace them.
What will happen if tire pressure is high?
Over-inflated tires can make the ride rougher, raise the possibility of a blowout, and increase the possibility of sliding. The center of over-inflated tires usually wears out first. This may result in A smaller portion of the tire’s surface area making contact with the road.
What happens if you put too much pressure on the tires?
The sidewalls and tread of overinflated tires grow tougher than usual, and the tire’s contact surface with the ground gets smaller. This shift in the footprint may result in decreased traction and performance, a bumpy ride, and altered vehicle control.
What happens if too much air in the tires?
Premature tire wear is inevitable. The core of the tread area wears down substantially more quickly than the outer borders of the tire when it is overinflated. They might only last half as long as they usually would because of this. Loss of traction may result from overinflation.
Does tire pressure affect braking?
Low tire pressure increases braking distances and makes steering and handling less sensitive. When a sudden evasive movement or emergency stop is required to escape a collision, this can be very risky. Low pressures also enable excessive tire sidewall flexing, which produces heat.
Should I put more air in the front tires?
In order to account for the greater weight of the engine and transmission, particularly on front-wheel-drive cars, the tire pressure is typically higher in the front than the rear.
How long should you let the air out of your tires?
Replace the cap by tightening it a few turns until air begins to hiss out. It doesn’t matter if it only hisses a little; as long as it does, the balloon will gradually deflate. It should just take ten seconds to complete the operation.
That concludes this article, where we looked at how to check tire pressure. Nonetheless, the answers to the following questions have been discussed:
- Why is it important to maintain proper tire pressure?
- How often should I check my tire pressure?
