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.

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..

I bought these hoses to replace an old set of the same on my RV. Ive had two of the old ones start leaking, one at the crimp, and one at the oring seal to the valve stem. The old ones were put on when the coach was built in 2002, so Im not complaining about the slow leaks. These hoses make checking and adding air easy. The new hoses look like they have improved the ends and the connector to the valve stem. Checking pressure should be done often, and these hoses make it easy. Only thing better, is to have a monitoring system for pressure and temperature so you can watch from the dashboard. Im thinking about that one........ 269273

Hoses are still working fine. I did add a tire presure monitoring system, and the sensors hood up easily to the hoses. I did use stainless screws and nuts to mount the brackets because the rivets had worked loose on the original install back in 2002 Screws and locknuts hold much better.

I used these on my 2007 Chevrolet 3500 dump truck, they are very easy to install, and on a chrome or stainless wheel simulator blend in pretty well. the only thing i didn't like about them is that the extnesions themselves ride right against the 4 decorative ovals in the wheel covers, which made me worry about them eventually rubbing through, so I positioned the mounts on the center cap where they would have the least tension or stress and wrapped a piece of EPDM rubber roofing around the braided stainless line, applied clear silicone to it and put a pipe clamp on it to ensure it wouldnt move to protect if from any friction. I figure I can suffer a little bit of looks to not lose air out of a tire while loaded. lol All in all they do work as they should and make it 100 times easier to check air pressures and add air if needed, if the ovals in my simulators were a little bigger I think they would probably fit better, they do fit great on my 2009 Delta dual tandem gooseneck equipment trailer no complaints on there at all :) 604140

Just got these in the mail yesterday, installed them today on a 2017 Forest River Forester (E450 Chassis). Just had to pry the wheel simulators off on the duallies and then needed to drill some holes for the brackets then pop-rivet them to the wheel simulator. Airing the rears is MUCH easier now. Next I'll be adding the EEZtire TPMS for monitoring tire pressures/temps while going down the road. 317728

Of all the parts I bought, this was bad. One of my tires went flat, had it not been for a passerby at the gas pump I would have ruined a tire. Then, you people wouldn't make my purchase right. This happened the second day on the road. Poor quality and poor guarantee. 485260

Easy to install, shipment was on time, accomplished in record time, and worked as advertised. 724798

This product makes it so very easy to check tire pressures on dual wheels. The struggle to check and fill the inner tire is eliminated. This is the second motor home I have installed them on. It’s really a time saver. 630844

Needed to upgrade for using TPMS sensors. Work great.. 616892

- WM8001

" Easy to install, with no special tools" This is a under statement. 1. Right angle drill will be needed. 2. pop-rivet tool will be needed. 3.Decor wheel liners made of stainless steel require very sharp drill bits. These were installed on a class A motor home with 19.5 dual wheels. The outside dual had to be removed and rotated 180 degree, because both valve stems were in the same rim opening. 576450

I off road on the beach in a Dually pickup and these are absolutely needed, however they leak all the time. Installing them although not hard, getting them to actuate the truck valves is a royal pain. I wish there was another option 350821

- WM8001

I had these on and older truck and they worked very good. Did not fit my 2016 3500 Ram according to directions. Installed them on an angle. 304710

thanks for the fast turn around, my husband will put them on the back tires on our motorhome so he will be able to put air in without taking the tires off. thanks again for the wheel masters 4-hose inflation kit dually-hub mount-wm8001 296899

The 4 hose inflation kit worked out great for the rear dual tires on my motorhome. The tire shop did have to put shorter valve stems on the outer tires to get the extensions on. But I was replacing the tires and needed new stems anyway. The kit was delivered very promptly as promised. This kit will make checking tire pressures and adding air much more convenient. 266333

Great company, good pricing honest people fast delivery. What else can I say very happy with this company . Would recommend them 256547

- WM8001

etrailer shipping was fast. My gripe is with the manufacturer. They should print on the packaging that this WM8001 requires a small 90 degree angle drill to drill the necessary 8 holes in your chrome hub cover. Shame on them! Luckly, one of my friends has one of these angle drills. 252107

Item was received in short order. Instructions were detailed for installation. I pop-riveted the extension to the hub cap. This completely stabilized the extensions from any movement. After installation we have completed several trips totaling about 1000 miles and have had no loss of air from the rear dual tires on our class C motorhome. My tire pressure monitoring sensors connect without any issues. Just recently checked the air after being in storage for three months and tires have not loss any air. Very satisfied with the the 4 hose inflation kit. 238567

This was just what I had been looking for and about half the price they charge at the RV stores 178530

Good products! 127286

Product is as described. I purchased this item because one of my rear dual tires was missing the kit. As of this review, I haven't physically installed this item but it looks identical to the existing kit installed on my motorhome. All parts present and build quality looks excellent. 82261
