Very robust design! This is going to stand up well.



by:

Worked perfectly for what I am using it for.



by:

Took me a long time to find a product like this but it was exactly what I was looking for.



by:

Heavy duty, well made.



by:

The only thing missing from the order was one nylock nut for one of the 4 attaching bolts. It fit exactly as I was expecting once the nut was replaced.

I'm glad this worked as expected for you Jeff. Let me see what I can do to help make up for the missing hardware, that's not a good experience.



by:

It’s solve my spare tire problem



by:

It mounted up as described with little difficulty and holds the spare tire solidly.



by:

Solid piece of gear. Works as advertised. Love etrailer!



by:

Great product. Very well constructed. Great communication with trailers during the purchasing and shipping. Will definitely use trailers again



by:

Just what I needed!



by:

Very well made.



by:

15 inch spare wheel and tire fits the front of my 5 x 8 v-nose trailer nicely with room to turn the hitch crank handle. Wish they had included a couple of 1/2 x 20 tpi trailer lug nuts. But I am otherwise very happy with the purchase. Very heavy duty.



by:

Will not work with 235-80 R16 wheels and tires. Not high enough.



by:

This tire carrier is very heavy duty. It is easy to install. I needed my tire to be mounted on the front of the trailer tongue. This solves that issue. The bolts that hold the tire are adjustable so it can take any tire you have. The only thing I think would help would be the lug nuts to be included or suggested to be purchased in addition to the carrier so that the right ones are used.

Still working as needed



by:

Easy to install and able to mount on the front of my trailer so I can still open my backdoor on my Toyota FJ.



by:

This has been an excellent accessory to my motorcycle trailer as it allows much more room to maneuver people, motorcycles and equipment around without constantly bumping into the spare. This is a quality built item that stays put once installed. Actually looks great and has enough adjustability to center itself so that it looks OEM once installed. I needed to order longer screws for my aluminum trailer frame but they were inexpensive and fit perfectly. I also ordered a locking hard-cover for the spare so it’s secure and looks great too.

Its been over a year in this mount still looks new. It has never moved or come loose and it really looks OEM especially with the locking cover I purchased for it.



by:

Price was fair with included shipping. It was delivered in 4 days!! It only fits up to 4in channel trailer tongue. My trailer has a 6" channel tongue so purchased (separately) 8" carriage bolts to work on the larger channel. Worked great! 225/75/15 tire fit perfectly.



by:

the Demco Spare Tire Carrier.....Great product, well made. Works as advertised...Only improvement would be if Demco furnished the two lug nuts.



by:

Good quality product. Doesn’t fit a 235/80/16 tire. Needs to be two inches taller.

You mentioned that it did not fit with your 235 80 16 tire and I wanted to ask a few follow up questions. Would you be able to send a picture to show how it is not fitting? What is the bolt pattern of your rim?

Here are three pictures of the tire and mount. I already have made a fix for it. So I’m good now. But l am trying to let you all know that for a 2358016 tire it’s to short. On the first picture the bolt in the center of the rim is the highest adjustment that it can go. So it doesn’t catch the top of the bolt pattern on the rim. So I got so flat stock and extended it. So it’s all good now. Thank you

I reached out to the manufacturer about your experience with the spare tire carrier. Since the carrier works with a wide range of bolt patters, the tire size can vary drastically and they do not have a specific max tire diameter that will or will not work. There are too many variables to take into account. The modifications that you did will work as long as the bottom side of the tire rests on the bottom plate of the tire carrier. There should be enough support on the bottom side of the mount to withstand that tire



by:

This tire carrier mount works great, super easy to install on our race car trailer and we no longer are tripping over the spare trailer tire inside the trailer at the race track. And if we ever get another trailer it will be easy to transfer over to that trailer.



by:

Strong rugged heavy duty



by:

I like the quality of this carrier but the description indicates that it fits a 4”x4” trailer tongue. The bolt pattern in one direction is 4 1/2” and the bolt pattern in the other direction is 3 1/2” (inside hole to inside hole) so it will not fit on my 4”x4” RV bumper without modification. I like the carrier enough that I will modify it to fit my RV and would recommend etrailer update the description. Also, there is already rust forming behind the upright support. If it weren’t for these two issues, I would have rated the product a 5..

Thank you for bringing that to our attention. Well have that info in our product description changed.



by:

I purchased this in April of 2023 for my side by side trailer. My trailer is in the AZ desert for half the year, not around road salt and is not used on any rough roads.

I just noticed the tire was loose and found the bottom weld of the spare tire bracket where it attaches to the upright had failed. A proper weld should not fail in 2.5 years without some unusual cause.

I have a ST175/80R13 spare mounted on it.

I've attached a picture. You can see where the weld failed. There is surface rust where it failed but it clearly didn't rust through.

I guess I'll get a chance to learn basic welding as an upside.



by:

The product was exactly as described. Very solid and well built. I wanted to use on top of a 4x4 rear bumper and it's not really designed for that. I knew that before I purchased but was able to modify to work by simply drilling out two holes near the vertical rear flange, securing the mount using the two provided bolts in the front and 2 J-Bolts in the back thru power coated pre drilled plates I found on Amazon with the correct hole spacing. Perfect!

  • Recommended Spare Tire Carrier for a Deck Over Trailer
    Hey Mark. I don't have a spare tire mount that's going to fit a 9" I-Beam but I've got a couple of other options I wanted to share with you. If your trailer has stake pockets one of these spare tire mounts would be what I recommend using. The Buyers Products Stake Pocket Spare Tire Mount item # 3375201012 fits stake pockets that are the standard 3-1/2" and 3-3/4" size. The Brophy item # SPTC is designed for 2" x 4" stake pockets. Both of these tire carriers fit all wheel sizes and lug...

  • Recommended Spare Tire Carrier for a Coachman Leprechaun
    Hey Ray. There's no bumper mount option for motorhome tires with an 8 lug pattern. All of our bumper mount spare tire carriers like item # UF15-954730 are for 8 lug trailer tires. The only solution I have for you is a hitch mounted spare tire carrier like the Roadmaster item # RM-195225. This spare tire carrier attaches to a 2" receiver and even works with dually spares. It has the ability to tilt out of the way and includes a 2" receiver built in that can be used for flat towing or other...

  • Are The Demco Spare Tire Carriers # DM15851-52 & # DM15851-76 The Same Except For Color?
    I was able to determine the information on the Black # DM15851-76 spare tire carrier was incorrect. It is the same carrier as the Silver # DM15851-52 with the only difference being the color. Both of these fit a trailer tongue up to 4" x 4". Thank you for pointing out the error on our site as I have had this corrected.

  • Spare Tire Mount for Trailer With 6" Tall Frame
    Hi Craig; all of our bolt on options like the # DL22145 with the offset max out at 5" tall frames. If you have room for it to sit on top the # DM15851-76 will work but you will need to get longer bolts locally for it to fit the taller frame. Outside of that, depending on the trailer and setup you can add a hitch and use the # e98ZR, or mount it underneath with the # LC159056, or if it is something like a utility trailer you can add a stake pocket and use the # 3375201012.

  • Spare Tire Mount And Hitch Mounted Cargo Carrier Options For A 1979 Airstream Motorhome
    Hi Eric, Airstreams typically have small tongues but if you have the space you could install the Demco Spare Tire Mount # DM15851-76. This clamps on to the trailer frame at the tongue giving you space for the hitch mounted carrier in the back. If not, you could also just get a weld-on receiver tube # 337RT25808B and weld it to the top of the bumper off to the side so that it doesn't interfere with the other carrier. If these won't work then send me some pictures of your motorhome and...

  • Spare Tire Carrier that Can Fit 4 inch Trailer Bumper
    We have spare carriers like the part # UF15-954730 which were designed specifically to attach to a 4 inch RV bumper which would be my first pick for your application but since the # DM15851-76 was also designed to attach to a 4 inch by 4 inch metal channel there's no reason it wouldn't fit either. The Ultra Fab would have better clearance to your RV wall like you mentioned since it attaches behind the bumper and not on top. I attached a review video for more info on this as well.
