Welded Spoke 6.5" wheel conversion for ATV tire

I am going to attempt to weld spokes in between the hub and rim while in a jig. Curious if you guys and gals think that tubing or solid would be tougher in use. thinking (8) per side and 1/4" to 3/8" size range. Just cutting the spokes away and using the hub for a conventional trailer wheel hub is my backup plan whick would only waste the $35 wheel. I just think I would like the spoke look better if I can make this successful.


EDIT: To include video link once done. Just came back from 15 mile test ride. Other than taking a small amount of power to pull the big tire at 10 psi, it rides very close to the same as before. The little bit of free spin wiggle I am seeing in the video is not detectable at any speed up to 55 thus far. Smooth and neat feel.

There is a reason why every spoke wheel I own is equipted with adjustable spokes to true the wheel after every major shock experience. The only rigid spoke wheels I recall were covered wagons which had wheels that exploded on demand.

Makes sense but I have never found a need to adjust a spoke in my life and bigger spokes welded in might not get knocked around as much ?? , Just trying something and wanting an opinion, I already acknowledged it might not work out so I see the potential flaws and failure modes, no help needed there !! I am willing to risk the $40... :)

Hey Doug,

My first reaction when I first read about your idea was that you must have fallen and hit your head :eek:!

Now, I am kind of digging it :D! There is no reason at all why this won't work well, assuming that it is accurately jigged up and you are able to get good welds. My vote would be to use five tubular spokes per side, with my reasoning being tubes would be more rigid than solid bars and ten spokes should be plenty while still providing interesting aesthetics.

What trailer wheel size are you using?

I say go for it (and put me on the waiting list for prototype #002).

It is 14x6, a bit concerned about swelling the tire out that much so gonna mount this freebie tire of the 26x8x14 size to get good measurements first. Shoulda done that first but this tire just fell in my lap by accident today.

I think I need an even # of spokes on each side to create opposing forces for acceleration and braking torque loads if I install at angles like stock, I am afraid if i just do them like an old wagon wheel the rotational torque from being driven and braking, might try to over stress them. ???

Got 3 more hours in on this project today...Got all the dimensions worked out, will double check all the #'s again tomorrow and finish the fixture. I settled on 3/8" 1018 crs for the spokes due to availability.

Got my dimensions all cross checked and confirmed, fixture jig done, need to remove a bit more paint before fitting and welding in spokes. P.S. I am experimenting with picture posting options so two pics of same thing here. let me know if you cannot see the one on the bottom !!

I can see the bottom pic. It is larger and properly oriented.

Used the threads in it for hold down. I have a fitted locating block attached in the bottom center of the hub and bolted thru to hold down tight. I could of used a plate and a nut, just thought the 1" thickness along with dead flat might facilitate more squareness along with the down pressure clamping force. Going to start fitting in some spokes tomorrow.

Wheel bearings on order for Wed. Hope to test then. Buddy give me his old 26x8x14 Good year Rawhides to install to take overall width #'s with. Sucked pulling it back off when the goal is to put a bigger tire on it. love how easy it installed and removed.

I hope that it works out and provides another option for atv tire mounting. It seems like it will be difficult to get everything perfectly centered and the weight mostly balanced, but you seem like a pro.

I worked a couple hours today and ended up getting the spokes made and welded into the left side of the hub and wheel. I'm not crazy about the layout but when working with fewer larger spokes I found you cannot create a criscross pattern because of the fat spokes so that limits options. Maybe come up with something better in a rev. 2 in the future, we'll see. I will make and tack in the other side tomorrow before removing from the jig.

It is centered better than the wheel is round according to the dial indicator. I will get my bearings in Wed. and see if I can detect any balance issues. before and after a new tire is installed. I think I am going with a Big Horn 2.0 26-9-14

Got it all spoked up and out of the jig this morning, Probably run it through the blast cabinet and paint it next. Going to try and do the rim in black and the spokes and hub in silver, shot the silver first to let it cure a day before trying to mask this thing up. Waiting on a tire so no hurry I guess.
