tire carrier engineering

[ALF]

Okay I'm buiding a rear bumper for my K5 (progress pics are in my sig) Although Rocklogic has been great and I do Like their carrier hinge I'm concerned with the design after hearing stories and seeing failure pics. I don't want to lose a tire on the freeway and have it take out a little Miata or something So I ask of all you "Offro Engineers" to put on your thinking caps and help me design a tire carrier that allows me haul a tire still open a tailgate and not have to worry about losing it

use the RL hinge (or that style) but use two of them. If/When I build a tire carrier for my bros jeep this is what I plan to do.

Search Shawn's post about his tire carrier. He captured his hinge double shear.

Look at half the commercial carriers out there. At least the ones for XJs(because thats what I drive) use exactly the same type of spindle and bearing setup that RL sells. IF they were flying off all the time the big comercial builders would not use that design.

I think you are safe just with the one. I did it and I aint skerd

I think this guy sells a double sheer kit for the spindles. He also has a slightly nicer hinge tube than the rockstomper one.

Here's an idea:

I mount my high lift vertically along side my spare tire. It is attached to the swing away by two 1/2" bolts that the jack "I" beam simply slides through. It is then secured by two coupling nuts with a 1/4" rod welded to the end to form a T handle to spin it on and off. I was getting an alarming amount of flex in my tire carrier assembly, and couldn't figure out a good way of shoring the whole thing up. So........I fabbed a quick support arm from my cage that ties into the hi-lift jack up higher, above the edge of my tub. It attaches using the same 1/2" bolt and T handle nut as the other two mounts. It prevents the entire thing from flexing and makes it a lot sturdier. I now have three T nuts to spin off to get to my jack rather than two. Also I have to spin off the top one to open my tire carrier, no biggie.
