Spare Tire Inflation Hose Kit Under Chassis Mount

It's important to make sure that your spare tire is properly inflated in the event that you need to use it, but it can be a real pain to access the spare when it's stored underneath your vehicle. The Wheel Masters spare tire inflation kit takes the hassle out of checking air pressure and inflating your under-chassis-mounted spare tire.


A 36" long hose lets you move the valve stem location of the spare tire to an easy-to-access spot on your vehicle's rear bumper. This means no more crawling on the ground or blindly reaching for the valve stem on your spare. And the stainless steel wrapping on the hose helps prevent it from cracking or leaking.


Installation

  1. Attach the 90-degree valve extender to spare tire's valve stem.
  2. Connect the hose to the valve extender.
  3. Run the hose to the desired mounting location on your rear bumper.
  4. Install the mounting bracket and attach the hose to it.
  5. Screw on the valve cap.

Video Transcript for Wheel Masters Spare Tire Inflation Kit Review

Today we will be doing a review of the Wheel Master spare tire inflation kit under chassis mount with stainless steel hose, part number WM82286-S. The spare tire inflation kit comes with a 36" stainless steel wrapped hose that allows you to move your spare tire's valve stem to your bumper. This spare tire inflation kit eliminates the hassle of crawling under your vehicle and checking the tire pressure in your spare tire. By moving the valve stem to the rear bumper it allows easy access to make sure that your spare tire has proper inflation. The kit comes with a ninety degree valve extender which attaches to your original valve stem on your spare tire. From the ninety degree extender you'll attach the braided hose and run it out to the rear of your bumper. The mounting attachment is also included with the kit with a couple different options for mounting. There's a screw that can be used or there is a bolt, a lock washer and a nut. Depending on your vehicle will depend on what style mounting you will choose.

We also found it helpful to use a couple zip ties to help secure any excess hose to keep them from flopping around or being damaged while driving down the road. A standard air chuck is used to inflate your spare tire using the tire inflation kit. The spare tire inflation kit also comes with a one year warranty. The spare tire inflation kit for the under chassis mount has double wrapping on the hose which helps prevent the hose from cracking or leaking. That will do it for our review for the Wheel Master spare tire inflation kit under chassis mount with a stainless steel hose, part number WM82286-S. .

I installed one of these filler hoses on the spare tire of my 2015 Ram 1500 about 1-1/2 years/ 20K miles ago. It worked flawlessly until I had a flat, and after removing the spare, I failed to secure the hose properly, and it dragged on the ground, damaging it beyond repair. I immediately ordered a replacement from etrailer, which was delivered promptly. I recommend without reservation both the product and etrailer.com to anyone needing a similar item. 439752

Valve stem 90 will not go on a valve extension and they only send you one 5/16-32 nut, so if you don't want to use the light weight bracket that they send and prefer to mount it through the bumper you will need to find some nuts. Other than that it is fairly nice part. I had some old metal valve stems and was able to utilize the washer and nut from them. 213289

This has made checking the air in my spare so much easier for me and installation was not hard at all. 248526

Perfectly when I get my oil changed I always ask them to check my spare.

I've has this product for 1/2 year and it works well. I have an SUV and mounted the hose under the rear of the SUV. The reason I subtracted 2 stars is because the nut holding the air fill connection is NOT stainless steel and is rusting. All other parts are SS. Its a shame that the mfg cheeped out on such a small part. 506572

This product appears to do the job intended; however, it may not hold air due to the two extra connections. The jury is out on that. On my Lexus, the spare tire inflation valve is on top. A true PITA. 612972


Comments
Great. Make sure the connections are tight. Had to air up the spare twice to keep dash warning light off. Slick.

Attached the tube to a spare tire in an internal wheel well, and drilled a 3/8 inch hole in the trunk 'floor' to provide access to measure the tire pressure without moving anything. The attached photo shows the end of the tube attached to the inside trunk floor, held in place with the provided bracket. After setting the tire pressure to 60 psi, this pressure has been maintained for 24 hours, so it appears the tube and fittings are air tight. 805869

This was easy to install. I'm very impressed with the quality. It makes checking the spare tire pressure easy. 803620

So far so good. Easy installation on my van's "Continental" style spare. Saves having to take off the wheelcover disc and chrome retainer rim. (neither shown in pictures). I can now drive with peace of mind about the status of the spare tire. 633648


Comments
My only complaint is that the nut retaining the valve on the bracket is carbon steel and of course rusts. Could not find a SS nut to fit so I made one from a piece of nylon. That will never rust! Otherwise an excellent product.

Good quality stainless steel hose and end fittings. Installed on my 2017 Subaru Outback to check the spare tire pressure regularly. Without this extension hose, it would have required me to empty out the entire trunk to access the spare tire. 470545

Product is good, but the seal at the tire valve is cheap and hard to keep from bleeding air 465963


Comments
The product is working out fine except that you have to be very cautious when you install it on the valve stem. To tight will create leaks...

This hose is just right to make checking that undermount spare tire a breeze. Installed in about 20 minutes. Make sure to use zip ties to secure the hose to the frame. I threw a few spare zip ties in the truck just in case. 458570


Comments
Hose is still working perfectly. No leaks and I am now confidant that the spare is properly inflated should I have to use it.

I purchased this item to replace an old cloth covered rubber extension hose to check my spare tire pressure . As my spare tire was over 6 yrs. old I purchased a new spare tire . After having my spare tire replaced with a new spare tire I checked the tire pressure pressure and it was ZERO LBS. the next day ! After checking the new spare tire and re-inflating the new tire it held pressure for a full week without the extension hose , it appears the old extension hose was cracked and leaking ? I installed this new unit and the tire and the new hose extension have held correct pressure for at least a week . This new unit is well made and has a braided stainless steel sheath . It cost about three times as much as a cloth covered rubber hose extension , but I think it will last much longer than the " cheapo " extensions? I used this on a Toyota Tundra 4 WD PU and go into some pretty out of the way places and always want a good spare tire available . Mounting for the new unit is very easy and you may be able to use zip ties and not need to drill any holes to mount it ? 438557

The kit was very simple to install and use. (Installed on 2015 Ram 1500 Pick-up) The unit does not leak air even after several months. A very high quality product, that I would buy again, and highly recommend to other motorists needing such an accessory. 346527

After a year, my evaluation remains the same. I highly recommend this product.

Top shelf product. Hated having to lower spare tire to turn off low pressure sensor. Now able to fill spare right at rear bumper. Fast shipping 330713

Kudos to etrailer! The product was received as described and at a better price than others offered. It was well packaged and arrived in a reasonable timeframe with the cheapest shipping. Although I haven't installed it yet, I've opened the package and inspected the contents. The materials all appear to be high quality and well made. Once installed, I will appreciate not having to drop my spare tire to check pressure or inflate it. It must be one of Murphy's Laws that it'll be the spare that causes the TPMS light to illuminate! 308904

I have two spare tires on my motorcycle trailer that are mounted stacked and covered, making them very unhandy for simple air pressure checks. I bought two of these air extension hoses and ran them through the flooring up to each tire, allowing me to do a quick air pressure check right from the front of the trailer! I was so impressed with the quality of these hoses that I bought a third and installed it to the spare tire on my truck! Thanks ETrailer for a GREAT, HIGH QUALITY PROBLEM SOLVER!! 295847

Works as expected. Makes it easy to keep spare tire at correct tire pressure. It was working fine after 8 years of use, replaced only to have a new look due to rebuild of back bumper and trailer hitch. 277570

length was a little longer than I expected but not too long. Mounting bracket is very convenient. Now I just have to watch to see if it holds air. 266539



- WM82286-S
by:

I could not get it to work properly, threw it in the trash. Either it would not let air in the tire fast enough or it would leak and leave me with a flat spare. 250599

Pretty easy to install as long as you have a hole for the mounting screw or bolt to go into. I did not have one so I had to make one and the frame was a hard steel so it was not easy to drill and I broke my tap and had to make a different hole. The mounting bracket is prettt light weight, but its not holding much and should not be under stress. However so far the product does what it was made for so I'm happy. I can easily check and adjust the spare tire without lowering it. 243250
