To change wheel and tire size?

[troutbum70 857]

Wondering what would be required to put bigger wheels/tires on my commando 800. I have included a picture of a of a 23*9.50-12 hanging on the tractor bolt holes correct but center hole to large. I would need to raise seat pan a bit to allow room for the chains.

That shouldn't be a concern.

The lugs hold the wheel.

I'd HIGHLY recommend changing over to studs and nuts.

 

Maybe a steel spacer to raise the seat pan?

 

[Burnerman 758]

Raising the seat pan isn’t that simple on these. It’s actually hinged in the rear and latches in the front. I guess maybe the supports could be spaced with wood or steel blocking where they bolt to the pan. 
maybe some low profile AG tires? Lol 

I’m going to be dealing with this issue myself here down the road. I guess the 800 tire size is an oddball. 

[ebinmaine 67,265]

Can you space between the transmission and pan?

[troutbum70 857]

 I think gaining some clearance for the fenders is the easier part, finding a wheel with a smaller center hole for the bigger tires may be more problematic. Or find an axle hub that fits the wheel, but made for a 1 inch axle. Or a whole different transmission/rear end. This is a much smaller project than what EB has got going. It would require spacers front and back on the seat pan which as Burnerman has stated is on a hinge at the rear. I have not done the research to see if there are tires out there at 22 inch's.

[ebinmaine 67,265]

Center size won't matter.

 

If you're looking for 22s maybe try ATV tires?

 

[troutbum70 857]

EB you state center size don't matter is feasible to rely on only the wheel studs with no support at the center? I am not familiar with atv stuff, do they run 22 inch rubber? I will research that possibility.

[Pullstart 62,783]

I have run “normal” wheels on the Commando 800 hubs with no ill effects.  I’ve also had 23” tires with chains on the same tractor, Rylee’s “Screamin’ Jimmy”

 

 

[ebinmaine 67,265]

There's really no weight bearing on the center hole.

That's more for line up purposes.

 

If you change to studs/nuts lineup and mounting will be much easier.

 

I'm not actually familiar with ATV tires myself. I've been looking at them lately for Colossus but decided to go with tractor tires.

ATV tires are sold in slightly different sizes than tractor tires.

 

[troutbum70 857]

So do you use the same size stud only longer and add nuts to the rear to reinforce the threads on the hubs?  I think some of my clearance issue is do to the chains being of very large link diameter plus they have the ice cleats that are fairly high, but they really dig in the ice when needed.

[ebinmaine 67,265]

The "stud" is a bolt 7/16 fine. I can't remember what length but I can check my stock.

The lug nuts are a standard part that fits lots of old vehicles.

 

 

Those chains are perfect for plowing so I'd make room for em too. 

 

 

[ebinmaine 67,265]

@rmaynard Bob may have stud/nut kits

[troutbum70 857]

I will check with him on the studs, and you bet my upper driveway is fairly steep and with water coming out of side hill it accumulates a lot of ice so the cleats are a big help.

MINE IS THE SAME TRACTOR,,,,DIFFERENT MODEL     AND 857.....

NOTHING RUBS  12 INCH WIDE  RIMS......24X12.00X12     NOTHING RUBS,,,,,,,,,,WELL,,,,NOT YET

I have room for the wheels are tires no problem, and a probably no problem with tire chains less the ice cleats. The chains with the cleats add a little better than an inch and a quarter to the tire height. Also a good looking herd you have.

7/16-20   1 1/2 LONG...............JUSSS SAYIN

[troutbum70 857]

So Burnerman 23x9.50-12's if it were not for the chains with ice cleats I would not have had to raise the seat pan, I raised the seat latch about 7/16's of an inch. As you can see in picture that gave me the clearance I needed.

[troutbum70 857]

So I have not got to putting in the studs and nuts, I assume the studs are threaded in from the rear of hub? Should the studs have flat washers to help protect the hubs from possibly cracking or even breaking?

 I didn't use them no issues.  Probably wouldn't hurt anything to use them

[troutbum70 857]

Okay my thoughts always is an ounce of prevention goes a long way and cheaper than the failure later.

[ebinmaine 67,265]

I've done both. No noticeable difference either way.

[troutbum70 857]

I think I am going to do the studs, as I think about it it makes sense.

[Mickwhitt 4,584]

I did the wheel stud modification on my WH and it looks great.

 

So much easier to fit the wheels too.

 

The nuts are old style Ford ones and are chromed. They look the bees knees.

 

[troutbum70 857]

And Mickwitt they look great, I will have to look through my junk I may have some old ford acorn lug nuts laying around.

I believe the old Ford lug nuts over here are 1/2" NF. Mickwitt might have used English Ford lug nuts.

Old Chevy lug nuts are 7/16" NF.
