The hot sun beamed unrelentingly onto my face as I lay on gravel at a sketchy impound lot in Fontana, California, wrestling a crappy contraption made of tube steel off the back of a dilapidated Jeep Grand Cherokee. How the hell did I get here? The answer to that question is simple: The Jeep gods sent me to pick up the Holiest of all Jeep Grand Cherokee parts: the coveted spare tire carrier. It was offered as a dealer-installed option in the 1990s, but few Grand Cherokee owners opted for it. Now it’s so rare that only a handful of images of it exist on the internet, and you can forget about hoping to see one in-person. Somehow, though, I just bought one, and I’m now going to give you an exclusive, up-close look at the rarest, most highly-sought-after part ever available for the first-generation Jeep Grand Cherokee. Prepare your souls.
Why The Spare Tire Carrier Is So Useful For A Jeep Grand Cherokee ZJ
This information you’re about to read is nowhere else on the web, because by the time the internet hit its stride in the early 2000s, there were probably only a dozen or so of these MOPAR spare tire carriers left in existence. The spare tire carrier is the ultimate optional accessory for a Jeep Grand Cherokee, in large part because of what 1990s auto journalists considered the “ZJ” Jeep’s greatest flaw: Lack of cargo space. When New Car Test Drive reviewed the 1996 model, it wrote:
The spare tire, stowed on the side of the rear storage compartment, cuts into the cargo space. The Grand Cherokee’s key competitors have moved spare tire stowage underneath, operating on the theory that tire changes will be extremely rare since so few 4-door sport-utilities ever venture into off-road regions filled with sharp rocks and the like.
Car and Driver’s review of the first model-year Jeep Grand Cherokee (1993) even mentioned the coveted tire carrier that is the subject of this article, writing:
If station-wagon capability is important to you, make sure you get the outside spare-tire mount. The inside mount stands the spare up on the left, just behind the second seat, where it hogs too much of the load floor.
Watch this Motorweek review and you’ll hear John Davis decry the ZJ’s upright spare tire sitting in the cargo area, saying:
The somewhat narrow Grand Cherokee has about 2.5 cubic feet less total cargo space than an Explorer, and the spare tire mounted back there takes up a lot of room. Jeep says they kept width down and the spare inside for better offroad maneuverability.
It’s one of three “misses” that Motorweek mentions in its conclusion, along with less-than-optimal braking stability and engine NVH issues:
The reasoning that Jeep gave Motorweek for packaging the spare in the cargo area makes sense. By mounting the spare there, as shown above, the floor remains relatively high, which is important since the fuel tank sits below.
In 1999, when Jeep replaced the ZJ with the “WJ” Grand Cherokee, the company changed its tune, appeasing car journalists by moving the spare under the floor. The result? The fuel tank dropped; look at how low it sits in this picture from aftermarket-bumper manufacturer Paramount Automotive:
The fuel tank is so low that a number of off-road enthusiasts have actually cut out the spare tire well integrated into the Jeep’s rear floor just so they could move the gas tank up and away from off-road obstacles.
But neither the ZJ’s upright spare nor the WJ’s tire well in the cargo area is the proper solution to Jeep’s spare tire packaging conundrum, because as I wrote in a headline a few years back, “The Proper Spot For A Spare Tire Is On The Rear Door.” Let’s quote that article’s main point:
Packaging the tire on the back door is simply the best solution. It doesn’t eat into cargo space, it doesn’t compromise ground clearance or departure angle, it doesn’t limit how big the spare can be (though it may require some reinforcement of the door if you put 40s on it), it doesn’t get too filthy during off-roading, it’s easily accessible and, most importantly, it’s downright sexy.
Seriously, show me one SUV that doesn’t look better with a spare tire on the back? Hell, even the tiny Ford EcoSport looks better with a big cylinder hanging off its tail.
Plus, you can customize these tire carriers with political opinions or funny off-road-y text, so that’s always fun.
I do mention that there are a few downsides to a rear tire carrier such as reduced visibility, fewer rear door options (hatch and tailgate are out), more difficulty opening that door (which has to be fairly stiff to handle all that weight), and a few more. But regardless, the rear spare tire carrier is the best spare tire carrier, especially for an off-road vehicle. There’s no question about it.
Picking Up The Rare Part From An Impound Lot In Fontana, California
The photo you see above popped up on my screen as I scrolled through my daily (okay, hourly) Jeep search on Facebook Marketplace. “Holy crap, it’s a factory spare tire carrier!” I exclaimed before jamming my phalanges hard against my keyboard until the seller and I had set up a time for me to snag the rare contraption the following day.
[Editor’s Note: Look, I am no one to judge anyone’s automotive fetishes, but damn, this contraption is so half-assed. Look how the re-located license plate covers half of the Jeep badge:
Someone saw this and said “ah, good enough.” Do people really covet these things? Really? There’s plenty of aftermarket options. I’m a little baffled. That said I’m not here to yuck David’s or anyone’s yum. – JT]
Unfortunately, the seller only had the following night after 8 P.M. available, but — realizing that this was a once in a lifetime opportunity — I jumped on it, and wrenched on that Jeep in the dark that Tuesday night.
I only managed to snag the hatch that evening, but I returned back on Sunday to snag the main swing-out carrier:
I thought I was paying $250 for this thing, which was already absurdly high, but after yanking the hatch, bumper cover, bumper, and the main tire carrier (which is part of the hitch), the seller began thinking I was ripping him off. “Why do you need all of those part just for a tire carrier?” he asked as he jacked the price up another $100. I wasn’t thrilled with this, telling him the tire carrier doesn’t work without the hatch, and that bumper isn’t going to be much use to anyone with a hole in it.
Anyway, I threw him another $40, because I kind of understood where he was coming from. The way Jeep mounted this tire-carrier required modifications to quite a few parts, and it was clearly an afterthought. Let’s have a look at the engineering behind this crude contraption.
An Exclusive Close Look At The Jeep ZJ Spare Tire Carrier
Okay, get ready for some hyper-exclusive content. Here’s how this super-rare tire carrier works. It all starts with a regular, run-of-the-mill Reese hitch [Editor’s Note: Who else just learned the official name of this thing right now? PS I read the comments and realized it’s a brand name, so okay, I get it no need to yell at me more. – JT], which is held to the bottom of the Jeep via six nuts that thread onto studs sticking straight down from the Jeep’s main structural rails:
Here are two of the three studs on one side of the Jeep (in the image, I’m actually removing the studs by jamming two nuts against one another, then putting a socket over top of them and twisting. The tension in the threads between the two nuts locks them into place, allowing for the stud, and not the nuts, to rotate, thus releasing the stud from the Jeep):
The Reese hitch that forms the basis for the tire carrier has been modified in three main ways. First, this bracket, which includes a wedge to slow down and pinch the swing-carrier when it closes, has been bolted on:
Then, on the passenger’s side of the hitch, the flat face perpendicular to the outside of the Jeep has had one hole drilled into it to hold the end of the pipe that the spare tire carrier rotates about:
Also supporting that same pipe is a bracket made up of a piece of square tube that slides right into the hitch’s lateral square tube. You can see that the internal square tube that clamps the tubular tire carrier is fastened to the hitch’s square tube via two bolts:
Okay so now that we know how the main tube (about which the swinging carrier rotates) is mounted to the vehicle (via the hitch), let’s look at the swinging carrier itself, which is shaped like a figure eight.
You can see in the photo above that the aforementioned stationary post that’s fastened to the hitch (and that bends into a vertical orientation as shown above) has some nylon bushings around it; those are there to reduce the friction as the main swinging tire assembly (which is shaped like a “figure 8”) spins about the post. If you look carefully at the photo above, you can see a bolt on the bottom flange near that lower white bushing; that’s there to act as a “stop” to prevent the tire carrier from opening too far.
The swinging assembly’s lower tube (the bottom of the “figure eight”) contains a little bracket that slots into the wedge I showed before, slowing the tire carrier down as it closes, and holding it in place so that when it unlatches there’s still a bit of friction.
The top “O” of the figure eight includes the cube(ish)-shaped bracket that holds the wheel and tire; there’s also a handle, latch, and rubber bump stop:
Here you can see the handle, which, when pulled, yanks on a little nub (via a cable) under a horizontally-oriented face of the tire carrier, actuating the latch directly above, on the other side of that horizontally-oriented face (this little metal cable needs repair):
Here is a top angle showing how that handle just pivots on a horizontally-oriented bar that’s welded to the two sides of the figure eight’s top “O.” You can also see the back side of the main bracket that the wheel and tire assembly bolts to (see the three lug studs, which here are just bolts). Also, there in silver (with a little bit of rust on top) is the latch, and on the left is the rubber bump stop:
If you look at the image below, you might have some concerns about this spare tire carrier’s structural integrity. Specifically, you might wonder how that single tube mounted to the hitch is going to hold up the whole figure-eight-shaped swinging tire carrier, especially with a heavy wheel and tire mounted up.
Well, where the hitch-mounted tube becomes vertical — I’m talking about the upright post with the nylon bushings about which the carrier swings — is actually reenforced by a steel bracket that ties into the rear bumper. Here’s a look at the bracket, which is simply bolted to the top of the bumper:
And here’s where it grabs that vertical tube (you can see a little marking where the bracket has held on for 30 years):
Here’s a look at the whole bumper, with the bracket mounted on the passenger’s side. The bumper is made of cheap, cheap sheetmetal:
In fact, because the bumper is made of such flimsy sheetmetal shaped into, essentially, a “C,” Jeep’s procedure for installing the tire carrier at a dealership involved fastening a metal strip between the bumper and the bumper bracket that holds it to the vehicle. Here’s a look at that stiffener meant to reinforce this side of the bumper, which is going to see loads from that bracket on the right that’s helping hold up the tire carrier via that vertical post:
I also found a reinforcement on the body of the Jeep itself, where the weight of the tire carrier and spare might push the bumper bracket down on a thin flange:
Here’s the steel bracket, which mounts via those two bolts you see on the flange above. It’s not exactly clear how effective this strip of steel would be at reinforcing this thin flange, but it’s there:
You really don’t want to get rear-ended in a ZJ, because the gas tank is just a few inches behind the cheap rear bumper, and the plastic bumper cover isn’t going to help you, either. That cover, by the way, features a rectangular hole to accommodate the bracket mounted to the bumper on the other side:
For context, here’s where that hole is located when the spare tire carrier is mounted up:
Okay, so now that we’ve discussed the hitch and the bumper-mounted bracket, let’s talk about the third location where this hyper-rare tire carrier is held down: The hatch.
I mention in the embedded Instagram video near the top of this post that this whole thing feels very much like an afterthought — it’s hardly an elegant bit of engineering — and nowhere is this more apparent than the hatch:
The hatch is where the swinging tire carrier latches when closed. You can see the latch in the image above just below that wiper arm; it’s part of a steel bracket that’s simply bolted to the sheetmetal hatch, crudely. Look at those allen screws just exposed! To the right and a bit below the wiper you can see the rubber bump stop where the carrier hits when you slam it.
Because this carrier covers the ZJ’s license plate location at the center of the hatch, opting for this now-rare bit of packaging brilliance required dealers to relocate the plate. They did this by drilling four holes into the left side of the hatch — two to receive rubber plugs and two to receive threaded inserts to fasten the plate. Oddly, it seems those rubber plugs are there to elevate the plate above the Jeep emblem; was Jeep okay with obscuring its badge? That seems a bit odd to me.
Just above you can see a small light. Mine appears to be missing some kind of cover/lens. I’ve been trying to find a photo of what this should look like so I can track down the parts (since I strongly doubt Chrysler developed a custom license plate light, this should be something I can find off the shelf), but so far to no avail.
Luckily, I thought to look at where the spare tire normally mounts on a Jeep Grand Cherokee. You can see that space above; there are two rubber bumpers on the driver’s side of the cargo area; the spare is squeezed against these bumpers via a J-bolt that hooks to the wall via the bracket shown above. You thread a big nut against the wheel, and it pulls the tire tightly against the wall, where the tire rests against the rubber mounts.
Vehicles equipped with the coveted-but-janky spare tire carrier don’t need that J-bolt mount, so dealers installed the black rubber cover you see above. Now that’s a random and absurdly rare part!
This Spare Tire Carrier Will Soon Adorn The Ultimate Jeep Grand Cherokee
Anyway, that was an exclusive the Jeep Grand Cherokee’s absurdly rare MOPAR external tire carrier is built. It’s not exactly a marvel of engineering (and I could just buy an aftermarket one that doesn’t hang so low and ruin my departure angle, though those tend to require a whole new rear bumper, and that changes the Jeep’s entire look), but it solves one of the ZJ’s biggest problems, and I’ve been drooling over it since I was just a kid; I can’t believe I actually found one only 90 minutes from me.
The tubular contraption will be a key ingredient in my quest to build the Ultimate Jeep Grand Cherokee, which will be based on a rare, base-trim (with crank windows and manual locks!) manual transmission model. The plan is to use OEM parts to build the ultimate overlanding Grand Cherokee, and given how important cargo space is for overlanding, this spare tire carrier is coming in clutch.
What a find.

This is without question, the Most David Tracy article yet.
I do love the way this thing is constructed. It’s both incredibly janky and elegant at the same time. Wonderful!
I’m with you on the Janky part. This looks like a kludge straight out of early 1960s British Leyland
It’s the Get ‘er Done quality with apparently negative zero concern for form that I deeply appreciate and do consider elegant in a fashion. Function yes, form, eh.
I don’t give a fuck about this tire carrier, but damn it David YOU do, and you wrote a most description article about this piece….how could I not read every word of it? You bunch of nerds here are automotive treasures.
I respect your dedication to creating a factory obscure build but this carrier is definitely janky and you could fab up a good one for about the same price.
There’s a guy who sells a kitty for the 80 series for the factory bumper for 520. It wouldn’t be too hard to modify or replicate

I can still recall opening and closing the one on a friends Jeep when I was a teenager. There was a huge mass about it when swingning, and a large thunk when latching. Was satisfying.
That thing is horrible. I used to have a 95 Isuzu Rodeo with an external spare. The mount was so much better engineered than that thing it makes me wonder why Isuzu left the market.
I also had a rodeo with that swing. It wasn’t made super well, but better than this keep one for sure.
This should provide added insurance against the ZJ’s affinity for self-immolation when rear-ended.
I’m surprised the license plate was relocated to the side and not onto the spare tire itself.
I guess they wanted to make sure there was a blank canvas for a “ɹǝʌo ǝɯ dᴉlɟ ‘sᴉɥʇ pɐǝɹ uɐɔ noʎ ɟI” spare tire cover.
Probably because then they would need to route wires to light up the license plate there.
David. The light on this bracket is probably pretty close to the OEM one (it is LED rather than incandescent).

And why wasn’t it standard?
Small crossovers of the time had exterior-mounted spare tires, fucking *FWD crossovers* not even real off-road cars like a Jeep LOL

I loved having the spare on the rear in my rav4 the cargo area was so deep because there was no gas tank or sub floor
Rav4s with a rear-mounted spare are one of my weird automotive fetishes.
skid plates not standard, spare tire not standard. A lot of the off road stuff on jeeps were optional back then because money and most were family hauling minivan replacements. Back in the early to mid 90s there was almost no aftermarket for Cherokees and Grand Cherokees for off road parts. I know I looked at the time.
I love how David’s version of something Ultimate is different then other people’s Ultimate. Diversity in car nerding is a beautiful thing.
Nerds gonna nerd and geeks gonna geek.For a long period, I was a Volvo 240 nerd/geek for a long time, and Volvo had a really deep Accessories catalog for them, and the geeks and nerds would go absolutely apesh!t over the rarest ones. So I get it. It doesn’t matter that this seems janky and there are very likely better solutions from the aftermarket, people will go nuts for this stuff.
Embrace your logical engineering self!
Don’t ruin your ZJ with this piece of gimcrack poorly engineered Mopar garbage. If you need floor space you have a truck. Put the harvested crap in storage and see how the “investment” appreciates with time.
But … but the ZJ itself is a piece of gimcrack poorly engineered Mopar garbage. Why not go all in?
Has someone told you Reese is a brand name yet?
They make peanut butter cups, right?
Oh Jason…
I recall reading in Car And Driver that when the Grand Cherokee was introduced, a team ran a nearly stock one in the Paris-Moscow-Beijing Rally. It did quite well, if I remember correctly.
I wonder what sort of spare tire carrier it had?
After the explanation, that tire carrier is more robust than I initially thought. As a comparison, what does the aftermarket offer?
Too bad DT is all about ‘stock’ stuff…. if you are going to use the tire carrier, why not remove that bezel that is recessed for the original license plate location, then fab up a door that is somewhat flush with the exterior of the hatch in the old license plate location…. then you can gain some storage space in the interior of the hatch…. probably only lightweight things, otherwise the gas struts won’t hold the hatch open (maybe upgrade to higher force struts….)
Oh yea, remove the ‘JEEP’ lettering of the hatch.
Reese is a brand name. Receiver hitch is the type.
Pedant says, hitch receiver.
I just remember that when I worked installing hitches at the turn of the millennium our showroom sign and the title of the parts book said reciever hitches.
But Reese is a brand name, one of the many manufacturers of aftermarket receiver hitches, surely can’t be an official part name.
Note for JT – Reese is a brand name (https://www.reese-hitches.com/). Other hitch companies exist (like Curt, Draw-tite, B&W, etc.), and they would happily remind you that Reese is not the official name for this category of hitch.
Reese is a brand name (a company that is an OEM and aftermarket supplier), not an official name of a trailer hitch
Looks like you took the words right out of my mouth!
I just cannot understand the fixation with this tire carrier. I try to be a “to each their own” kinda guy but these carriers are objectivly bad. I cannot imagine paying 300 bucks for one.
They often broke and had sagging issues with the stick size tire on it. ZJs are old enough at this point you can find a good aftermarket from a rusted out one or that somebody is parting out. Even one that mounts into the reciever hitch is going to be a better bet…
Same reason meh cars from the 80s and 90s are priced so high now. He wanted it when he was young and now it’s rare and he can buy it.
At least a lot of those cars are decent automobiles.
That tire carrier fails at its basic function.
It’s like the Yugo of tire carriers
IF you think this looks like it was designed in a back yard of Metro Detroit, that’s because it WAS. This was outsourced by Chrysler to a father and son duo that were friends with my Grandfather. It was originally mounted to a metal bumper, not a hitch, and the plate was mounted to said bumper not the hatch.
I got to play with the prototype, and yeah it wasn’t changed much…
This makes so much sense! The entire time while reading it I was like how did a manufacturer make this?! I mean it is Chrysler so there’s that but this is even beneath their usual standards.
Can you tell me more please? david@autopian.com
That is wild (and yet, totally believable). I love that there’s members in the community waiting to drop Easter eggs like this onto our heads.
The amount of half assed engineering that went into making this work is amazing. I am happy you found it, but please take it apart to clean and repaint/powdercoat it. It looks like it could use it.
That is sooo much more elaborate than the swinging carrier on my CJ-8. Hope yours lasts as long.
JT. I agree with you 100%. That tire carrier looks like pure ass hat engineering of the highest level. And DT likes that shit? In the real JEEP world the after market is huge. Because the shit that’s offered is far superior to the shit offered by the factory. Thank God. DT should be spending his bones on finding the holy grail of women, and stop pissing in the wind at crappy auto parts. (Or a decent bit of bud for $300, or edibles,) And stop obsessing over stupid crap. “Go sit in the corner for a while David and think about the stupid shit you’ve already done.” /s
Poor DT, he really got a Colonel Lingus tongue-lashing! 🙂
Errr. Well said.
David, you are quite possibly the greatest car nerd ever.
That’s a lot of effort for a Rube Goldbergian Continental Kit that makes getting to your cargo and parking more difficult.
This is exactly why i refuse to go to 35 inch tires. Because then i would need to relocate the spare to a swing. The idea of unlatching a swing (usually a two step process) then opening the top glass then the bottom gate just to get the back open exhausts me just talking about it.
