How to Put Air in Tires?

When you have an underinflated tire, you’ll need to add air to the recommended tire pressure.
(If you need to check your tire’s air pressure first, we’ll show you how to in the next section.)

You can pump your tires with an air compressor or a portable air pump that you can plug into your car’s 12V socket. You’ll also need an air pressure gauge to check the pressure.

If you don’t have these, go to your nearest gas station with a coin-operated air pump facility. Some gas stations also provide free air service. 

Here’s how you add air:

  1. Determine your car’s recommended tire pressure. You can find it on the driver’s side door jamb sticker or in the owner’s manual. The ideal tire pressure for most cars is around 30-35 PSI. For some, the recommended pressure in front and rear tires may differ.

    Important: Don’t mistake the pressure value printed on a tire’s sidewall as the recommended pressure. That’s the maximum cold pressure your car tire can withstand.
  1. Press the end of the air dispenser against the tire’s valve stem. You’ll hear a hissing sound as air enters the tire. Filling the underinflated tire can take from 10 seconds to a few minutes, depending on how much air it initially had.
  1. Detach the air hose from the tire valve if you’ve added enough air, and take a reading using the tire pressure gauge. Gas stations may have an air hose with a built-in pressure gauge, but it’s better to double-check using a dedicated air pressure gauge to be safe.
  1. Repeat this process until you’ve achieved the recommended air pressure. Follow it for other tires with low tire pressure.

Note: In the case of an emergency, you can use a bike tire pump if its air dispenser is compatible with a Schrader valve (a car tire generally uses a Schrader valve, whereas a bike tire may have a Presta valve). This approach, however, will understandably take a lot of time and effort!

  1. If the tire gauge pressure was too high or you overinflated tires while putting air in them, release the extra pressure using the valve. Press the pin at the center of the valve stem in short bursts using a suitable tool (like a blunt-head screwdriver). You’ll hear the hissing sound of the air jet coming from the tire valve.
  1. Check the pressure with an air pressure gauge to avoid deflating the tire too much after releasing some air.
  1. Put back the valve cap on each tire.

Adding air to your tires is pretty easy. 
But what if you just want to check the air pressure?

How To Check Your Tire’s Air Pressure

For this exercise, you’ll need an air pressure gauge (pencil-type or dial-type). You can find one at an auto parts store or a gas station.

Here’s what to do:

  1. Take off the tire’s valve cap and keep it in a safe place.
  1. Press the open end of the tire pressure gauge firmly against the tire’s valve stem for a few seconds to let the instrument read the pressure. Repeat this process for all tires of your vehicle. Check the spare tire pressure as well.

IMPORTANT: You should check the tires’ inflation pressure when they are “cold.” This is after parking your car for three hours or longer or driving it for less than a mile at a moderate speed.

A tire gauge pressure reading under other conditions will be less accurate as tires heat up while driving, increasing the inside temperature and pressure. Remember this, especially while driving to a gas station for air or using the free air service on a highway pit stop.

Now, let’s go over how frequently your tire pressure should be checked.

How Often Should You Check Your Tires’ Air Pressure?

Car maintenance and medical health checkups are alike; the more you delay them, the less they help. Maintaining proper pressure isn’t difficult; you just need to remain consistent.

Most modern cars also have a Tire Pressure Monitoring System (TPMS) that alerts drivers about low tire pressure through a dashboard warning light. However, you should still do a routine manual inspection to maintain proper tire pressure.

Next, we’ll cover how the correct pressure helps you drive smoothly and safely.

Why Is It Important to Have the Correct Tire Pressure?

Both low and high tire gauge pressures are detrimental to the tires’ health and overall driving experience.
Here’s why: 

A. Underinflated Tires

B. Overinflated Tires

Let’s address some questions about tires to help you make better car maintenance-related decisions.

3 FAQs About Tires

Here are answers to a few basic questions regarding car tire maintenance:

1. Should You Fill Your Car’s Tires with Nitrogen?

There are no clear benefits of filling nitrogen in your car’s tires against regular air. You may have heard claims of improved fuel efficiency, but there’s not enough proof. Nitrogen also costs you more than air.

Tires filled with pure nitrogen could ensure lesser pressure loss with time than those filled with regular air. However, the gas available for automobile use generally has lower purity.

That said, you should still routinely check the tire pressure.

2. How Long Do Tires Last?

A new tire will generally last 3-5 years or 50,000-75,000 miles, but you should get a tread depth inspection done by an auto repair or tire shop every 3000 miles. Replace tires with a tread depth of 2/32 inches or lower. Check if your tire brand has a warranty covering the mileage or tread depth.

Nevertheless, you should replace tires that are over 10 years old, even in case of low usage, as they’ll be more prone to tire failure. 

3. How Can You Extend the Life of Your Vehicle’s Tires?

You can extend tire life by:

Even a flat tire from a small puncture can be patched up to extend tire life to a certain point.

Wrapping Up

Having the correct pressure in your car’s tires safeguards their longevity and provides you with a better driving experience. Make sure that you don’t overlook this easy maintenance exercise and carry it out routinely.
