How To Put Air In Dually Tires

How To Put Air In Dually Tires

Are you looking for strong and reliable tires? The good news is that these qualities can be found in dually air tires which can be purchased from most local car shops. 

The even better news is that caring for these tires is not that different from maintaining regular tires. You just need to fill them with air consistently to make sure they’re in top condition.

Here is a guide of simple step-by-step instructions on how to put air in your dually tires.

Short Answer

Fill the outer rim of the tire the way you would normal tires. To fill the interior of the tire, you simply remove the hubcap and fill the air into the inner part of the tire via the valve.

What Do You Need to Put Air in Dually Tires?

Before beginning to place air in the tires, you must be sure to have the right tools for the job. 

Luckily, this project doesn’t require much – all you really need is a flathead screwdriver to pry off the center cap and hubcap. However, you will still need the following essentials:

  • Flathead screwdriver
  • Tire valve extender
  • Air pump or access to a gas station

You can choose to buy your own pump, or you can put air in tires at the local gas station. Most of them have pumps, and many even offer free air with the purchase of gas. Once you have access to a pump, most of them will also tell you what your tire pressure is currently at. 

You can also invest in a hammer to put extra pressure on the screwdriver. If your tire has smaller holes underneath the hubcap, then you will need to invest in a tire air valve extender to get the air pump to reach into the holes.

Steps For How to Put Air in Dually Tires

Ready for the fastest, most efficient way to keep your dually tires full? Here are step-by-step instructions on how to put air in dually tires.

Step 1: Find an Air Pump

Filling the outside layer of the dually tire with air is almost exactly like filling up a regular car tire. You simply find an air pump (invest in one or go to your local gas station. WAWA has free pumps for use). 

Step 2: Find the Valve

Pull your car up next to the air pump and find the valve on your tire, set the air pressure on the machine, and unscrew the valve. Place the pump nozzle into the car tire and leave it there until the machine beeps, signaling that your tire is filled.

Step 3: Repeat the Process

After the machine beeps, screw the valve back closed and move onto the rest of your tires.

Step 4: Remove Hubcap

To begin filling the inside of your tire with air, use the screwdriver to gently pry off the center cap and hubcap. Begin by inserting the flathead screwdriver into the space and then apply pressure to force it off.

If you feel as though the hubcap or center cap is going to break, then remove your screwdriver and attempt to pry off the cap in a different location.

Step 5: Fill It Up

After removing both the center cap and hubcap, you can then begin filling. You should see holes beneath the hubcap (the size of these holes differs). For most vehicles, the holes are large enough that you can simply reach your hand in and unscrew the valve. 

Take the air pump and insert it into the tire valve. The pump will beep when it reaches the tire pressure set. At this point, take out the air pump and screw the valve back shut.

If the holes are too small for your hand to fit in, then utilize the air valve extender and use it to remove the caps of the valves. Proceed by attaching the air pump to one end of the extender and inserting the other end into the valve. Proceed as normal.


It is important to keep your vehicle in top condition to avoid accidents, especially your dually tires. These are powerful tires that need plenty of pressure to help you avoid getting stuck in the mud or tow your boat to the lake. They won’t perform at their best if they’re a little flat. 

Keep this step-by-step guide in mind when you realize that your dually tires have low pressure. Fill them up right away and experience the power that these wheels are capable of.
