Wow! At a minimum, I think you'll need a new wheel and probably new lug nuts. Hopefully the studs are still OK, but check them carefully.

I dont see how the studs could be any good either.. yes to all of your questions, I would start at The dealer. You are supposed to check the tightness upon putting the tractor in service and every 50 hours. A lot of guys don't, and everything is fine, But this time everything was not fine. I don't see how anything but the tire can be salvaged. good luck

If a break down isn't going to cost you alot of money or kill you, I might try some big thick washers. Take off the nuts, put the washers on and then the nuts, and then tighten and hope the washers bend into a rough taper to take up the slack and roughly centre the wheel holes on the studs.
I also add maybe a third to the torque spec to help keep things tight and hope you don't snap a stud.
I found a couple lug nuts I could turn a half turn at my 50hr service which surprised me, but I guess that's why you're supposed to check.

I know that oversize lug nuts are available in certain sizes for just such an occasion. Whether they are available for your tractor I can't say. You would need to take a lug nut to your local NAPA type store or tractor repair mech. and match it up.

I second the vote for the washers, maybe even make a stack of 3 of different od's weld them together then grind them into an arc. That will be a whole lot cheaper than new rims and might back the nuts off the studs far enuff to get good thread.

New wheel or good used wheel, in this case you will probably have stress cracking in the wheel you now have. lug nuts all need replacing.
At least see the dealer, and get the proper rim size, then google for a replacement.

The washer idea may work in the short term but I would get some new rims on order and swap out when they come in. The rim center hole should be very tight to the tractor hub and it looks like yours is wallowed out a bit. That should be where the weight is carried with the nuts just holding the rim tight to the hub,
You will need new studs and new rims, so rather than take a chance on damaging the wheel hub, get the new rim now and replace it.
Check all the bolts now to make sure they are tight.
This reminds me that I need to check mine with a wrench, rather than just visually as I have about 50 hours on it now.

Last year I happened to notice that a couple of nuts had backed off (fallen off!) of one front wheel on my Kioti DK45. I was lucky that the others were still tight, so no damage to the wheel. I finally found some with the same thread at the local Kubota dealer, but the head is a different size so I have to use two different sockets when I check the torque!
I don't think it would hurt to try the washer-cone approach others have suggested...if it doesn't work out, you can still go to a bunch of new parts.

If this vehicle did 50 you would have to replace, but my neighbor who is a mechanic for the state parks had a large deer back hoe in with the same problem. The holes were worse, but he got some plate, cut it down, drilled a hole and welded it on.

He also advised the owner to start looking for a new used rim, but felt the fix would hold a long time.

RoyJackson · May 29, 2012

I'd replace both the rim and the studs...a temporary repair might be necessary for the short term, but the permanent fix should be replacement.
Right off the bat, I suggest you check torque on all your wheel nuts.

I also suggest you consider torque stripping. Once the nuts (or bolts) are torqued, use a paint marker and paint a line across the fastener (nut and stud or bolt) and on to the wheel. As long as the paint line isn't broken or misaligned, the torque is correct. This is a pretty simple way to make the wheel fastener torque check visual.

Gary Fowler · May 29, 2012

That would work if the welder was good or just weld up the holes and redrill. If I was going to weld on it, that is what I would do, plug weld the holes up and redrill them. They dont have tapered holes (at least the ones I have seen) because they are reversable. The tapered nut seats on the square face. It will take some precision hole lay out and drilling to get them perfectly aligned.

I had the same thing happen to a wheel on my 16ft tandem axle trailer. Had to replace he studs, get new lugnuts, and a new rim. I use the old rim as the spare now, but just for short distances as I have to check/re-tighten the lugs very often.

Hammy · May 29, 2012

This happened to me with my MX5000. When I first noticed it, I tightened them all back up but they didn't hold long. The wheel was shot due to the stud holes all messed up. I had to replace the studs as well. I got the wheel and the studs/nuts from the dealer. They were cool enough to loan me the tools to remove the old studs and install the new ones as well.

My advise is fix it correctly, you have a nice tractor.

Good luck

I suggest you buy the rim from the dealer...

candyman · Jun 1, 2012

took your advise got new rim, nuts, bolts & xtras to have . my torque wrench only goes to 160 # i think the required torque is 180 or so #`s.

this time i`m going to tighten the nuts down good & tight.

For future information. Some OEMs and wheel manufactors sell wheel lug reinforcement rings. These don't need to be welded on unless the wheels are damaged.

Don't forget to torque stripe the nuts and studs!

Chilly807 · Jun 1, 2012

Just a thought.. the front wheels on my L3400 don't have tapered holes, so the nuts are turned around so the flat end of the nut is toward the rim, and there's a lockwasher under the nuts. If you had the tapered end of the nut facing a flat hole I think it would rapidly wear into the steel rim due to the small contact area.

You should be able to see what I'm talking about in the attached picture.

Your rim MAY have had tapered holes and the nuts just came loose, too.
