Jeep CJ Spare Parts Tire Carrier
When I lived on the East coast, I used to wheel with Rick Boiros
and the "Old Colony Four Wheel Drive Club" out of Massachusetts. A
couple guys in the club had spare parts tire carriers where they
would have entire front axle outers to hold on their spare tire.
All of these were done on fabricated tire carriers, but I figured
I could build one off the stock spare tire carrier. I thought about
it a while and what I came up with was so simple, I wished I'd done
it sooner. This modification could also be done easily to many after
market spare tire carriers.
I've seen some spare parts tire carriers that even have a knuckle
on them, but I figured spindle out would be enough for me. The
tricky part is providing a mounting surface for the spindle that
is out far enough that you can bolt a tire to the brake hub and
not so far out that the tire becomes a giant lever waiting for
the correct pressure to rip off your tire carrier.
The first thing I did was remove the stock tire carrier and grind,
cut, and pound out the three bolts that hold on the spare. After
removing the mounting bolts, I cut off the end right off just outside
of where the two cross braces come from the top bar to the box (see
I then removed the internal brace inside the box. I took the
original end of the box and bent it a bit so it fit inside the now
shortened box. I welded this in place, then I took a piece of
sheet metal and welded it over the end of the box so I had a clean
surface on the outside with no holes. Next I broke out a 3 1/2"
hole saw I purchased for the project and cut a hole in the sheet
metal. I took a spindle for a spare Dana 30 and placed it in
the hole and marked out the bolt holes. Drilled out the holes
and blasted the whole thing with flat black spray paint.
After it was dry, I took a spindle with short axle shaft and bolted
it on with five 7/16"X3/4" bolts. I slid on a brake hub with bearing
and secured it with two spindle nuts and locking washer. A spare
hub went on next which holds the short shaft in place. I didn't
put on a spare rotor, I figured it would just add weight. I put
a bunch of washers behind the studs to make up for the room of
the missing rotor.
I took my creation and bolted to the Jeep and put on my spare
tire a 33"x12.5" BFG MT. It could have been about 3/4" closer,
but it looked great. It is "full floating" too, which
will surprise someone when the lean against it and it begins
I got the my full floating spare tire carrier done just before
my trip to Las Cruces for the Winter Meeting. I hadn't tested
it yet off road, so I was a bit nervous about it. It survived
The Gauntlet, Wolf Run, and Broad Canyon with no problems and
received rave reviews from other four wheelers.
When I was wheeling out in Moab a couple months later, I was coming
down a real steep rock and managed to bend the entire carrier up.
Probably if I used a 33"x9.5" tire for a spare, this wouldn't
be a problem, but I was using a full size spare.
A couple weeks later the carrier came in handy
when I was wheeling in Farmington. A friend managed to break
a lock-out and sheer all the studs of in the brake hub except for
one. Rather than drill out all the studs, we just used the
lock-out and brake hub from my spare parts carrier. Currently
it is bent up and has a ruined brake hub on it, but it still
holds my spare!
Spare parts tire carrier II coming soon...
