2"x2"x1/8" tubing for carrier

hello all

im having trouble getting 3/16" square tubing for my swing out on the tire carrier. for up to a 35" tire do you think 1/8" would ok if i gusset at tall the joints?

Seems a little thin to me. Hold out for the thicker stuff. Have you tried a scrap yard?

What about 1/4" wall? I can easily find the 2"x1/4" wall stuff in the drop yard at my local place. Better to have more than not enough. I'm not sure I'd even use 3/16 wall if you're gonna be carrying a 35. My bumper is made from 3/16 and the carrier is 1/4. The bumper flexed where the spindle was welded in until I got Zach's mega spindle that went all the way though my 5" bumper.

well my bumper is 2" x 4" x 1/4" and my spindle goes all the way through. i think i would have been ok with a gusseted 1/8" carrier but 3/16" is definitely enough. that seems to be the material used on most aftermarket bumpers.

1/4" wall for the carrier is overkill. You want to save on weight whenever possible. 3/16" works just fine when designed right.

IMO 1/4" is a bit ridiculous for a tire carrier. I have a buddy than ran his 40" spare on our tire carrier and it is made with 3/16", No flexing and no problems

i have had 35's on the ones i have built with.120 wall which is 1/8" but its round tubing not square with no negative impacts on its structural integrity. just my 2 cents

rusty is right you dont want a 200 lb bumper with another 70 lbs of tire

Don't use 2x2x1/8 wall you'll be sorry. I did and it twisted and wobbled all over the place. I rebuilt my hitch mount tire carrier using 2x2x1/4 and it is the cat's meow. Definitley not overkill or too heavy...IF YOU USE THE RIGHT PIVOT AXLE! I used a 3/4-10 grade 8 bolt on my first one and it was a nightmare opening and closing it. I have a great solution but I have to become a vendor before I can offer it.

IMO if you design it correctly and gusset it, it should be fine.

The key is to triangulate the assembly and add gussets where needed. 3/16" would be better, but if 1/8" is all you have then by all means use it.

I would not design it so that the bottom hinged section is the only thing holding it up though. If you could use at least 2 pieces that tie into the hinge point, I think you would be fine.

Do you understand what I'm trying to say regarding the main hinged arm?

I've built quite a few rear bumper/carriers using 2"x3"x1/8" for the main swingarm and 2"x2"x1/8" for the center upright and "A" frame pieces..

The 2x3 resists twisting at the pivot tube alot better than the 2x2 square tube.. I think it also looks a little more "proportional".


I run a 35" spare with steel rim on my own CJ and know of at least a few guys running up to 38" rubber on my carriers with that 1/8" wall swingarm.

And that was the problem with my first tire carrier made entirely out of 2X2X1/8 tubing. The swing arm twisted. I still use the uprights on my new one. They work fine.
