Many car owners no longer find it necessary to do car maintenance at home. They can learn how to drive and buy any car they want without bothering to learn car maintenance basics.
If the car needs cleaning, they drive into a car wash. If the car needs some tuning, they drive into an auto repair shop.
Even the mere task of putting air in car tires is no longer common sense among modern drivers. All you have to do is drive to the nearest gas station and have the service crew fill your car tires for you.
However, despite the advantages of these modern services, learning some essential car maintenance will better benefit you and your car. One of the basics you should be able to do on your own is how to put air in car tires at home.
First, before you can fill a car tire with air, you need to know how to determine how much air each tire needs. You can do this by obtaining a tire pressure gauge.
A tire pressure gauge is a handheld device that is used to measure how much air pressure is present within a tire. There are three common types of tire pressure gauge:
The pencil type and dial gauges are more common, but you need to be able to read or interpret their measurements.
Digital gauges, on the other hand, display the exact measurement reading and don’t need to be interpreted.
All three types of gauges are commonly used the same way, using the following steps:
Air pressure is usually expressed in psi. A tire will need more air if the pressure gauge shows a reading that is 3 psi below the recommended measurement or level.
For example, if the tire’s recommended pressure level is 30 psi, you’ll need to add more air if the actual reading falls below 28 psi. Also, under-inflated tires can lower your car’s gas mileage by 0.2 percent per 1 psi drop.
Sometimes, the rear wheels’ recommended air pressure may vary from the front wheels’ recommended level. That’s why you need to closely check each of the tire’s maximum tire pressure before proceeding to add air into them.
To put air in car tires at home, you’ll need an air compressor that you can hook to your car’s power socket, cigarette lighter, or battery terminals. A portable air compressor is most recommended as you can store it in the car’s trunk and use it whenever and wherever needed.
To add or put more air in car tires using a portable air compressor, follow these steps:
Some air compressors have advanced features like auto shut-off, where you can set the maximum pressure and the compressor will automatically shut off once that level is reached. This kind of feature protects your tires from being over-inflated.
Learning how to inflate car tires on your own has several benefits, such as:
By checking your car tires’ air pressure and inflating them as needed before leaving home, you can skip waiting in line at gas stations or service stops to have your tires checked and filled up.
You can inflate tires on your own whenever and wherever necessary. This is especially helpful during tire emergencies when you're stuck somewhere, and no service station is in sight.
You can save around 0.6 to 3 percent on gas mileage when your car runs on properly inflated tires. By being able to maintain your tires’ recommended pressure level, you can up your savings and improve gas mileage.
Proper inflation gives your tires better traction and handling on the road. This makes driving safer and prevents road accidents due to tire problems.
In conclusion to this guide, here are some helpful tips that you should know when checking tire pressure and adding air:
Now you’ve learned how to put air in car tires at home.
