Video Transcript for An In-Depth Look at the Wheel Masters Spare Tire Inflation Kit

Today we'll be reviewing the Wheel Masters Spare Tire Inflation Kit for the Trunk Mount with the Rubber Hose part number WM82286-R. The Wheel Masters Spare Tire Inflation Kit comes with a 36" rubber hose that let's you conveniently inflate and check the pressure on your spare tire without removing everything from the trunk of your vehicle. To accomplish this it allows you to connect the 36" hose to the original valve stem on your spare tire and 00:00:28 a remote location it allows you easy access for checking the pressure in your spare tire. The kit comes with an elbow that will be screwed onto the original valve stem on your spare tire. This will allow for the spare tire cover to be set back in place and not damage the hose or the valve stem. Next the end of the rubber hose threads onto the end of elbow and you will route the rubber hose to a convenient location in the trunk of your vehicle. On this particular application we found an area just behind the rear tail light that seems to work pretty well that's out of the way. A small L bracket also comes to mount the other end of the air hose. To do this you can either use a sheet metal screw or the bolt with the lock washer and nut.

Depending on your application, will depend on what sort of mounting style you will use. To mount the rubber hose to the bracket you will push the hose up through the hole in the bracket and put the nut down onto the threads, tightening it down to secure the hose to the bracket. The kit also comes with a new cap that you will install on top of the end of the rubber hose. When the need arises to use your spare tire you will just unthread the elbow off of the original valve stem on your tire and put the cap back on it. That will complete the review of the Wheel Masters Spare Tire Inflation Kit for the Trunk Mount with the Rubber Hose part number WM82286-R. .

ABSOLUTELY PERFECT PIECE TO RELOCATE AIR FITTING ON OUR 807711 CURT 807711, FLEX-AIR 5TH WHEEL PIN BOX. LONG ENOUGH TO MAKE IT TO THE REAR OF THE BRACKET FOR EASY ACCESS TO AIR UP.

by: Donald 05/07/2023 One Year Later

This spare tire inflator kit makes checking those hard to get at tires that hide under the vehicle very easy. Some spare tires now have TPMS on them so being able to check your pressures prevents that message of a low tire. The kit was very easy to install, and I just attached it to one of my license plate mounting screws.
This is the third one I have bought as they work really well on any vehicle. I have also spread the news to my friends who also have purchased them.

Great It’s so nice not having to the spare tire under the truck to check the tire pressure

by: Randy 02/26/2022

Just what I was looking for....and it’s made in the good old USA! Something of this nature needs to be a quality item that will not leak air. After reading the reviews, I felt confident that this was the one to buy. I’ve only had mine installed for a couple of days now, but so far, it appears to be air tight. It’s mounted on a GX460, with the bracket located on the right side of the trailer hitch utilizing an existing hole. Sure beats having to crawl underneath the beast to check (or add to) the spare tire’s air!

Update: After using this for a year now, I can say that it’s rock solid with no air leaks. I actually have one installed on two different vehicles. Very pleased would highly recommend.

As other Subaru owners have written, the spare in the back has the valve facing downward on my Subaru Forester. I have a lot of stuff in the back of my Subaru and it’s not easy and convenient to check the tire pressure in the spare. With this 36 inch hose and the elbow fitting that you attach to the spare tire valve, this makes it just as easy as when I check the other four tires on my Subaru.Love it.

This is awesome to hear. I am going to be honest I had no idea the Subaru's had that issue but it is cool to see this used as the work around. Great setup for easy access in the trunk it looks great. Of course you hope you never have to use it, but I bet it is nice to know it is ready to go if need be.

by: SM East TN 02/17/2024

I was wondering about something like this and when I Googled it this was one of the items that came up. Once I was able to determine how it worked, I decided to order.
I was able to install this in the trunk of my Honda CRV with no trouble. I just left the hose wrapped up in the wheel well under the back carpet as I don't carry a lot in there anyway. Now when my Low Tire emblem comes up on my screen, I won't have to haul out the tire to get to the tube where you put the air in.
The guy that mows for me was so impressed, he swore he was going to order one as well.
I also posted the pix below to my Facebook page.

@Raymond Small things can equal big convenience! Glad it's working well for you, Raymond. What vehicles are you using this with?

by: NM_Bob 03/14/2017

I'm using the Valve Stem Extender for its intended purpose, to be able to check the spare inflation without emptying the back of the hatch to reach the spare. What made this a must have is the fact that the hold down mounts the spare valve stem side down in the tire well. After finding a spare flat at one time (didn't need it but noticed it) I realized that having a flat spare is about as useless as it gets.

When installing the flex hose to the 90 degree adapter, I noticed that the "nut" portion of the hose seemed a little tight on the swivel, but a drop of lube and a little working back and forth and it spun on just fine.

I highly recommend this product if you have a spare that's really buried like mine.

The extender is still in place, making life just a little easier.

by: J. Perez 01/15/2024 One Year Later

The spare tire in my wife's Subaru sits with the valve facing down. Before getting this, we had to take everything out of the back and completely remove the tire to check the pressure and top it up. Now it's quick and hassle free. After a year we've had no issues with leaks. I couldn't recommend it more.

Still holding up over to regular use and no issues.

I used this extension on my Reese Gooseneck really helped or speed up the process of adding air to the unit, when it was needed.

by: James 01/02/2019

pricey, but high quality construction.
Subaru secures the spare with the tire valve stem facing the bottom, puts a tray with the jack on top of the spare, put another tray with tools etc. on top of the jack tray and finally puts the main cargo area deck over that. No wonder nobody checks the spare tire pressure. With the Wheel Master extension kit, I can check the spare tire inflation just by lifting a small hatch in the cargo area. 30 seconds versus 10 minutes to disassemble and reassemble everything - no brainer.

by: Les 12/08/2023 One Year Later

These tire valve extenders are great and the kits come equipped for a complete installation. I have installed them of all of my cars and my kids cars. They are so good that I actually now check the air is my spare tires more that twice a year. I check it every week of so when I check the rest of the tires. Installation include a Subaru, Matrix, Ford Expedition, Ford F-150 pick up, and the Toyota.

by: Ron 02/13/2024

I have struggled for years wrestling with difficult to access spare tires in trunk wells and underneath vehicles. It was easy to put off checking spare tire pressure because it was such a pain. The Tire Inflation Kit extension hoses make life so much easier and now I check the spare tires on my vehicles much more often. Thank you for a great product!

BECAUSE MOST CARS HAVE A SPARE TIRE MOUNTED IN THE TRUNK WITH THE VALVE STEM FACING INBOARD, SERVICING THE SPARE MUST BE DONE BY REMOVING IT.
THE TRUNK SPARE TIRE INFLATOR KIT MAKES IT EASY TO SERVICE SPARE TIRE PROPER PRESSURE.
NO MORE REMOVING THE TRUNK FLOOR AND SPARE TIRE. THE KIT MOUNTING HAREWARE ALLOWS YOU TO MOUNT A VALVE STEM IN THE INTERIOR OF THE TRUNK.

by: Richard M 10/29/2019 One Year Later

This was my third extension hose. The first two were cheeper but they both leaked air. Not what you want. This one does the job. Great product.

After a year still working great. Would not hesitate to buy another.

by: Ric B 05/12/2015

I've used this product on other cars in the past with good results. Specifically, a 2001 Audi A4, 1999 Audi A4, 2004 Subaru Impreza WRX, and 2007 Volvo S60R. This time I purchased it for the compact spare in my 2015 Audi A3. Unfortunately it doesn't work well with this car. The end of the valve on the spare is right up against the trunk floor with no room to fit the rubber hose or the 90º adapter. I would have to retrofit some other sort of valve to the wheel or build something padded to create a bit of space which would then make the carpeted floor uneven and not sit right. The design of the wheel securing mechanism doesn't allow the wheel to be flipped over to be valve side up. This is a good product but not compatible in my particular case this time. I will repurchase though for any future cars with compatible spare wheel configurations.

I ordered two of the spare tire hose kits for adding 3 ft to two tractor tire inner tubes to float a pontoon lift into a lake in northern Michigan. I called Etrailer and spoke with Noah, I told him what I needed and he placed my order and shipped them that same day. The hose kits arrived in time and they worked like a champ. Great job Etrailer!!!

by: Clyde K.K. 12/25/2018

Great product for checking hidden spare tire, and filling air into it without dropping the spare tire down from underneath my Highlander. The length of 3 feet is more than enough to mount the refill nipple on my trailer hitch. Really easy to install. Enough hardware supplied. I used a plier to make sure the connectors were secure enough so the air will not leak (just a couple of turns).

by: Tom T 08/06/2017

I have added this spare tire inflation kit to my 2017 Expedition to eliminate crawling under the car to check the pressure. The whole kit is first class. Doing business with etrailer.com has been a nice experience. They are first class too.

by: Pete G 01/13/2017

Exactly what I needed to keep a better eye on the tire pressure of the spare. Will save lots of time and grief without having to almost completely disassemble the trunk in order to get to the spare.
Easy quick and simple installation with the hardest part being to figure out how to best route the hose and mount the bracket.

by: Les 09/12/2024 One Year Later

It makes checking the air in spare tires buried beneath mounds of stuff in the back of my SUV so easy that I actually do it.

by: DAVE 12/18/2024

No more removing my spare tire to check the pressure!

by: Craig 09/03/2024 One Year Later

Hi, after 1 yr still working well and holding air just fine . Only minor gripe is the nut that holds this to my hitch is rusting…easy replacement.

by: Roy 07/01/2025

Received on time. Perfect fit. Holdds air with no leaks. Very well made.

by: Darrell 04/04/2025

I put this extension on my Reese goose box to air up the airbag from the side of my truck, worked perfect.

by: James 04/22/2023

Great product and easy installation. Works as proclaimed and would highly recommend.

Best Spare Tire Valve Extension for Jeep Wrangler JK Spare Tire with Cover
I have a solution for you, and the Slime Dually Valve Extender Kit # SLM20140 is definitely going to be flexible enough to use on a Jeep Wrangler's covered spare tire since it is a rubber hose. However, since it's only 8-1/2" long, I don't think it's going to be long enough to stick out behind the rear of the tire and allow you access to the extended valve stem very easily-especially if you have larger tires than the stock tires that normally come on the JK. For that reason, I recommend...
