I started this tire carrier recently for my tj. The mounts are getting welded to the corner armor and I may add a couple bolts near the mounts that bolt all the way through not just the nutserts that hold the armor on.

So here's the run down.

4 old heims recycled from my control arms
2 spare 7/8 tube inserts
2 7/8 machined fine thread castle nuts from ace
2 pieces of 1.75x.120 wall tubing from an old buggy that I cut up.
3/16 this plasma cut parts I designed myself including the main piece, 4 heim mounts, and a high lift jack mount not currently pictured yet.

All in all I'm about $10 in because all the parts of cut from scrap. I had to buy a couple 7/8 fine thread castle nuts to use for inserts. I had 4 spare 5/8 bolts I'm using for mock up but they are all too long so I will have to buy some bolts and other hardware to get it all right.

I had to modify the side that will open. The box in plate came over to far so I trim it back and re tacked it.

Here it's open on its own mounts for the first time. There is still tons of welding to do.

I gotta ask, is it really a tire carrier or armor against a fracking truck? Seriously what did you use for backing/support for the mounts, inside the tub? that sheet metal is kinda thin on my LJ.

The armor is currently bolted to the body and the mounts are welded to that. I am however working on a bracket that bolts through the armor to the rear cage mounts.

Right now nutserts are holding the armor on but all the spots I can they are getting drilled out and through bolted.

I do live in west Texas so a fracking truck rear ending me is a definite possibility.

I'm really not sure I'd mount the thing like that: it's still basically a bunch of relatively small screws though sheet metal.. The metal itself isn't substantial enough to support that kind of weight without deforming or metal fatigue. Just vibration alone has to take its toll when it's all loaded with stresses like you're going to be looking at there. You're talking some pretty major leverage on that right side sheet metal.

It'll work fine. There are plenty of armor mounted tire carriers out the from good companies. I'm not reinventing the wheel here.

It's 28, 1/4" counter sunk tapered head bolts. Some of which are through bolted and as stated above more are going to be through bolted. The whole back of the jeep would have to fall off. Also the back passenger corner is designed to take some load from the stock tailgate and tire. That's at least 60#. That has been removed so I'm not really adding as much weight to the corner when opened as it seems. I can figure the weight at some point but all together the tire and wheel are around 80# and the swing out is about 30-40#. So that's only 60 extra pounds to that corner when it's open. Which is spread across the entire piece of body armor.

It holds the tire fine but fixing the gap will bring the tire against the carrier. It has a small gap now. Pictured is a 37" tire on the highest setting.
