Checking and maintaining proper tire pressure is important for ensuring a safe, smooth ride and maximizing fuel economy, but it can be a real pain with dually tires. The Wheel Masters inflation kit takes the hassle out of checking air pressure and inflating your dual tires.

Two hoses extend the valve stem location of the inner tires to the outer wheels. This means no more crawling around on the ground or blindly reaching for the valve stem on the inner tire. Two 90-degree hoses are also included to make it easier to access the valve stems of the outer tires. And the stainless steel wrapping on the hoses helps prevent them from cracking or leaking.

Hub-Mount Installation

Video Transcript for Wheel Masters 4-Hose Inflation Kit Review

Hi there, dually owners. Today, we're going to be taking a look at Wheel Masters tire inflation kit.These would be great for you RVs and even your larger trucks 'cause when you have dual tires, typically, your valve stems are in difficult to access locations, and, sometimes, you even have to remove the wheels just to check the pressure and inflate it.But with this kit, our valve stems are extended and brought out onto the side of our hub, making them easy to access, so we can ensure that our tires are inflated properly at all times.This way, you can ensure you and your passengers are going to be safe on your long travels without having to get out, crawl on the ground, or take the wheels off just to make a check.The hoses themselves have a stainless steel braiding, which is going to ensure they're very durable, so they'll stand up to any debris that might bounce up on them on the road. The stainless steel means that they're going to be rust-free, so you're going to have corrosion resistance. It's going to last a long time.The hub-mount design is going to be more permanent and more stable than your wheel-mounted designs. They just clip on and spring load into place. The bracket's securely mounted to the hub using rivets.

This is going to keep it nice and solid, much more than your wheel-mounted ones would be. This can be a real benefit when going to inflate your tires because the bracket's going to hold it nice in place, but you have to push kind of hard with your air chuck to get air to go in it.The kit comes with four hose extensions. You'll receive two straight and two bent, with either your 90 or 135 degrees. This combination will allow you to adapt to various wheel shapes and valve stem locations that are on your wheel. Some wheels have the outer rim, like we have here, with a valve stem that's pointed in towards one of the holes, where one of these would really be necessary in order to inflate it.Your inner tire is always going to be difficult to access on a dual rim, just because the stem is on the other side, and often you can't reach between the two tires to inflate them, so that extra length is really going to help.That completes our look at Wheel Masters 4-hose inflation kit..

The wheel master WM8110a valve stem extensions for hub mounting on my 22.5 dually's worked great. I was able to to install the valve stem brackets on huds with the supplied parts (pop rivets and SS brackets) without removing the wheel hub cap by using an offset electric drill. Complete kit and easy to install

- WM8110A

Great product from etrailer as usual

- WM8110A

I was looking for stainless Steele’s braided valve extenders for our motorhome with a 3” 90 degree turned me find the perfect kit. The kit arrived after only a few days and each piece was a perfect match. Easy to install and now no more worries about tires losing air. Thankyou Phyllis and etrailer!

Still working great!

One of the extenders with the 90-degree angle connector acted like it wasn't depressing the tire stem which made it hard to either add air to the tire or to obtain an accurate reading. I removed it for that reason. The other one seems fine

- WM8110A

Needed some vehicle specific valve extensions, wanted two day shipping . . . reasonable price, excellent packaging, shipping and even a call to let me know when they were shipping. As a 20 year veteran I find this to be one of the best companies I have ever dealt with. Highly recommend and I will be back, thank you . . .

Ask the Experts about this Wheel Masters Tire Inflator

  • Availability of Valve Extenders for Inner Dual Wheels
    Most of the valve stem extenders we offer, such as the # WM8110A that you referenced, are 4-piece kits. But we do offer inner-wheel-only extender sets such as the Wheel Masters # WM80092. This kit features two 8-inch stainless extenders that mount on hand-hole brackets which are included. This kit fits inner dually wheels from 16 to 19-1/2-inches.

  • Difference Between Wheelmasters Valve Stem Extenders # WM8110A and # WM8004
    The difference between the two kits is the type of wheel they are designed to fit. So since you have aluminum wheels without wheel liners you need the part # WM8110A which were designed for attaching to that specific wheel style. The part # WM8004 is for wheels with wheel liners and attach to them instead so the clips would not work for you.

  • Will 90 Degree Hose Work on Valve Stem Pointing to Inner Tire
    You will not need any type of special tool to install the Wheel Masters 4-Hose Inflation Kit # WM8110A and you will be able to use the 90 degree hose on the outer tire whose valve stem points to the inner tire. The reason for this is the flexibility of the the hoses; they are designed so that you can flex them if needed so you won't have an issue with the angle. I have added a link to a video of a similar inflation kit being installed which should help give you a good idea of the installation...

  • Wheelmasters Inflation Kit that Fits 22 inch Diameter Wheels
    Wheelmaster does offer an inflation kit that was designed to fit 22 through 24 inch dually wheels with the part # WM8110A but the kit you mentioned would not fit as it is designed for smaller wheels.

  • Actual Dimensions of Wheel Masters 4-Hose Dually Inflation Kits WM8001 and WM8110A
    The Wheel Masters 4-Hose Inflation Kit # WM8001 fits dually wheels from 16- to 19-1/2-inches. I went to our warehouse and pulled a kit to measure the actual length of the hoses. I also measured the similar kit # WM8110A which fits 22-inch aluminum duallys. In both kits the straight hose (without the right angle bend) measures 13-inches tip to tip. In kit # WM8001 the right-angle hose measures 10-inches from bend to tip; in kit # WM8110A the right-angle hose measures 14-inches from...
