How To Inflate The Dually Tires And More…

“Dually tires are a pain in the ass!” Not my words but the words of a friend who recently visited me wanting to know how to inflate dually tires. To be fair to him, inflating dually tires is virtually impossible and requires you to twist, turn, crawl, and even pray just to achieve the right position. Unlike the single tires, most dually tires stem comes facing backward which leaves you with limited options while inflating them. And when they happen to be facing forward, they come with a seriously awkward angle.

Now, if your vehicle is fitted with dually tires, you may be lucky enough to find that the rims are correctly aligned for easy access the inflating valve. Unfortunately, many dually vehicles will agree this is not normally the case.

One of the most widely used methods which I personally use is using an inflator with extended metal valve stems. On top of inflating, they are great for deflating and checking tire balance issues. I would personally vouch for the ones with a 45 degrees chuck and 90 degrees twisting chuck which allows you to easily access the hard to reach inner stem.

To avoid backlash from rubber valve extension owners, we must say they aren’t bad. However, most users have complained that they tend to come loose due to the vibration and the centrifugal force.

If you don’t feel comfortable using the above-stated formula, you can also install the valve extension. They will certainly reduce the TAT for inflating and deflating your tires. However, I always advise people to consult their service provider before trying out something new. This is because valve extensions may certainly provide convenience in terms of monitoring and maintaining the tire pressure but special attention need to be taken when installing them to ensure they are safely done and displays accurate information.

As a footnote, you also need to carefully mount your dually tires. The outer wheel valve should never be lined up with that of the inner tire. Instead, they should be opposite to each other to avoid running into each other way. After all, prevention is better than cure.

Recommended Pressure for Dually Tires

How proper you maintain your tires generally dictate how safe your vehicle is. One of the cardinal aspects of dually tire maintenance is proper spacing between the rear tires and the sidewalls. It’s important to note that dual tires tend to deflect outwards when under load. If they happen to excessively deflect, they may come into contact with the sidewalls which may lead to serious damage.

Ensure that your tire pressure is properly maintained to prevent them from getting damaged. Ideally, it should be 60psi for the front tires and 55psi for the rear.

Dual Wheel Tire Sizing and Tread Depth 

Another important factor to consider is the size and the tread depth. These two factors affect how evenly weight is distributed on all the four tires. The difference in tire height leaves one tire shouldering majority of the load leading to uneven wear and tear.
