Well I really hope this works and I got all my dimensions right!

Starting to brianstorm a spare tire mount to support a 40, so this is great and I am excited to see how it all comes out for you.

I'll post pics when i get it mounted up, got a few more changes to do and picking up machined bars tonight. Then I'll have to figure out the actual spare holding attachment, trying to think of some cool ways to do it fancy like.
The base of the spare tire mount will be mounted to the machined bars correct? Will it be bolted to the bar?
I was thinking of using a spare unit bearing, but would need to render it "fixed" when the spare is attached so the wheel wouldn't move around freely.
I knew a lot of guys who carried a spare spindle assembly and hub on their spare carrier and some of them left the hub unlocked and just let the tire spin.

I have seen trailer spare mounts that include a spindle, it's not a terrible idea.
Yes, the spare holder will bolt four bolts on top of top xbar and four bolts on face of xbar. I haven't decided how fancy I want to get here. Did some brainstorming with Blaine earlier. I'll start with some cardboard, and maybe put it into cad. I'd like to try out the sendcutsend site that @sierradmax used.
i had a jimmy rigged wheel spacer to fit the spare onto, but it was a PITA so i rigged up a cone and T bar and like it much better. on the gate it will be holding weight while pulling horizontally your center has to be strong or maybe a small drop stoop to aid carrying the full weight on a horizontal pin.
i'm 45* in the bed so it's not as drastic and it'll be strapped also.
drop stoop might not be bad idea instead of holding that monster and fumblin with a pin.

Got the bars on tonight. Turned out pretty nice, it carried my weight well can't quite tell if it will sag under spare bouncing or not.
I don't love the license plate mount, need to figure that out after I do the spare mount.

homemade, i might have an extra steel cone, if you need 1.
a small shelf to put that big ass wheel onto so your not trying to hold it while fastening. the top of the receiver might work, didn't notice it yesterday.
and you have the program info? those are pretty cool.

Ahh I see. I haven't decided if I want to do a bolt pattern or center screw. Do you have a link to your post that shows how you did it? I think the bumper is an ok intermediate step, I'm planning on keeping the mount simple, pulling the tire tight to the crossbars. I definitely prefer a 2 person lift but I was able to man handle it solo on the exogate.
I do have the .stp file for a bar I could email. They're slightly different top to bottom and specific to my install.
i didn't take pics or post much about it, i just switched it the other day.
it's pretty crude nothin i would think you'd want hanging off that fancy aluminum ..........i just happened to press 2 cups/cones if you wanted 1.
jack the wheel up behind the gate and figure out your rim center stick out/off from your frame there, and how much structure is required, that might effect your clamping decision.

I’m guessing this way of mounting spreads the load across the rear and thus elminates tailgate sag?
Just trying to follow along. This is a great looking project.
What math goes into figuring this all out and how much weight it can hold adequately?
What do you need math for?
Exogate hinges hold up the tire and gate just fine.
Exogate hinges attached to the tub corner do not cause it to fail.
1.5" x 2" x .188 wall rectangular tube is stronger than any aspect of the Exogate hinge and tub corner with just a single piece.
Simple observation negates any math required.

Ya, as Blaine mentioned zero math. The only bit that isnt way stronger than exogate is the wall at the backside of the hinge bushing. Exo doesn't use a sleeve in bushing fit like Blaine used so it's a 3/4" hole instead of .375" but also doesn't clamp up on the rotating piece like the exogate does. I ended up with .250-.375 there.
The clamping to the driver side totally eliminates sag while driving, there still may be sag when swung open.

Was working on the spare holder bracket notional dimensions and wanted to show part of the why this design was so appealing to me. My tailgate was not long for this world I fear. The box that the tailgate latch mounts to was pulling out of the tailgate skin. 0.100 ish sheet metal is all that's holding the 125lb spare assembly. The tailgate tends to twist due to a single driver side latch. I can't recall who but someone else under Blaine's Tj tutelage solved this with a second lower latch.
Doesn't matter now. The tailgate is just a moving panel that stops stuff from falling out the back and gives a few fasteners a place to get the skin to act as a shear panel.
