Video Transcript for Demco Spare Tire Carrier Review

AJ: What's up everybody It's AJ with Today we're going to be taking a look at this Spare Tire Carrier from Demco. As you can see, we've got two of them installed on the trailer. You're not going to want to two of them in at the same time, but just want to show you your options. You've got the silver one over there, or the black powder coat one over here, either way, whatever fits your trailer or whatever you want to put on there. It gets the tire out of the trailer, up here saving you space there to load up with more stuff.

Taking a closer look at the different finishes here. You see the silver one is actually smoother than the black powder coat one. It doesn't have the dimples and stuff like that in it as this one, the black powder court one does, which actually this one matches the trailer more, so we'll probably stick with this one because it blends right in.We decided we we're going to mount it here on the side, our carrier mounts on four-by-four tongues. And this one clearly isn't four-by-four, but it's still.. The brackets here sandwich the frame.

And it's strong enough to where I'm going to shake the whole thing. It's not going anywhere. This carrier is not moving. It's going to keep the tire on here nice and secure. Now this spare tire carrier is made to fit the bolt patterns of four on four and five on five and a half.

Now how it accommodates all the different bolt patterns is, you just loosen this bolt here in the middle, which moves this backs plate off, which gives the bolts room to move around. They sit in the screw from the back, and as the plate tightens up, it keeps them in place.You loosen it. You can move them freely to fit the bolt pattern of your tire. And once you find that right, spacing for it on your tire, you tie this middle bolt back down, and it'll be stuck in place. Now it's kind of hard to do in its upright position like it is right now.

But in the install, we'll show you an easier way to do it with your tire. Now, whether you pick the silver finish, or the black powder coat finish, they both have a 500 hour salt spray rating, which means it's going to hold up the rust and corrosion overall. Although I think the spare tire carrier from Demco is a great option, keeps your tire up and out of the back of your trailer, giving you more room for the stuff you want to haul. Keeps up here on the side. I can still work my jack, get a tool box here, you can still get to that.Because the other ways you can smell the spare tire is the U-bolts. Well, those usually lay right here on the A-frame of the trailer. And it's just not a lot of room for that. It would be in the way of this handle or whatever I need to get to. Or you can put it on the trailer, it can stick out more. It's not what I want, I want it up and all the way like this. And it just provides the benefits of being able to do that. Another thing is it's really easy to install. So let me show you how we did that.Okay so, the first thing you want to do before you get it installed, is let's go ahead and line up our bolts to the bolt pattern on our tire. It's way easier to do it now, than when it's sitting up, and you loosen this and the bolts move all over, and you have to try and do that several times. You should do it here. Trust me. So I'm going to loosen this little bit. We already had it set earlier, but I just want to show you how to do it. So now these are loose, when you get it, you'll want to put your tire on top.There we go. So now we know it fits this bolt pattern. We can tighten this back down, and it's good to go when we put it on trailer. Now we'll want to go ahead and put our carrier on the frame, in the position we want it. Think we'll put it right about here. Make sure you give the tire enough space from the trailer here. That way it doesn't hit. We might move out here just a little bit more, give it plenty of room. inaudible 00:03:30 this on top, go ahead and drop the bolts now. There are four of these, dropping into place, and to put the plate on here, and just do this hand tighten, put the nuts on hand tighten them to the bolts and then I'll double-check and make sure that the frame is in the middle, because if you don't line up like that, then the plate's going to. As you tighten down, it might go that like that slightly, or twist like that. We want it nice and in the middle, that way the pressure holds it evenly. All right, now we'll go ahead and tighten down our nuts.Now I'm going to kind of go around and try to get them on evenly. Look at that, it's on there nice. I'm still going to give a couple more turns with this, just to be sure. Now it's time to put the tire up there. Now this is what I was trying to say earlier. We had it laid on the floor, and we got these bolts spaced out to the bolt pattern here. It's way easier to do that when it's on the ground, and tighten and loosen, than trying to loosen this and have these falling up and down, fumbling with the tire up there.We got it all in place. So it should just go right in there. It's just fine. Now we'll put on the lug nuts, the lug nuts aren't included in with the spare tire carrier. You'll need to make sure you get the right ones depending on the rim of your tire. If you have steel aluminum, make sure you get the appropriate lug nuts. So you're going to put these on hand tight now, then I'll tighten them down. And once you get the lug nuts tightened down, you're good to go. And that does it for our look at the Demco spare tire carrier.

Trailer tongue tire carrier mounts your spare tire up and out of the way. Base attaches around trailer tongues up to 4" x 4". Accepts wheel bolt pattern from 4 on 4" to 8 on 6-1/2". Silver powder coat finish resists corrosion.


It was easy to install and fit on my trailer tongue just fine. Appears to be solid and well built. I also got the spare tire and wheel from etrailer. It's one of those be sure to take it, but don't want to use it items.


I have a 20 ft. Cargo trailer V nose with an extended tongue. This is a robust tire carrier that works great in this application. One star down because I had to buy longer bolts for my 6 inch frame.


This is a great Spare Tire holder, very well built, very sturdy. Not flimsy like other spare carriers .

I added it to my motorcycle trailer, spare tire is mounted out of the way too.


This is a well built tire carrier. Just what I was looking for. Excellent service and fast shipping from etrailer, well done,


So sturdy and solid. Works great on my trailer with 2x4 aluminum rails.


It was a good heavy tire mount, the only problem was it did not fit over 4" rv square bumper, it was only 31/2" between bolt holes. I had to re-drill outside bolt holes to mount, it was a little trouble but works fine.


Works as advertised. Seems very strong.


The service and delivery was exactly as you said it would be. I was thrilled. Thank you so much.


Very well made spare tire mount made of quality steel. Great workmanship!


Great quality!


The spare tire carrier was exactly what I expected. Installed it on an Aluma Trailer. Easy to install and very good structural quality. The ease of adjustability is a huge plus for a range of tire/wheel sizes.


Perfect transaction. Item was priced fair and arrived in time for my trip! Will deal with again.


Didn't fit the back bumper of my camper.
had to modify it. My bumper/ tube is 4" square i assumed they all were 4".
