Just finished mounting my tires on 21" split rims. Was not looking forward to doing this after reading about the problems forum folks have experienced. But it was very easy. Universal tires and tubes and flaps from Lang's worked great. The flaps had a greasy coating on them which made everything slip 'n slide easily. I used a turnbuckle to pull the rim together to the point where the valve stem hole was just clear with the rim ends staggered. Pushed and prodded things in place and then backed off the turnbuckle. Made the final move with two half-rounds cut from 2x6 and a small hydraulic jack. We did 5 wheels in a hour and ten minutes with 20 of those minutes working on the first one. Good learning curve !
Good to hear. How did you fasten the turn buckle to the rim though?
This brings up a question I have been wondering about, why not use a rim spreader to take off and mount tires? Is that not what it is made for? Has anyone had any trouble with one bending the rims out of round or any other thing that would cost to repair? Just wondering as I will have to demount all my tires when I get that far.
Tim: The turnbuckle had hooks on each end which made it simple to fasten into the 2 wheel nut lugs closest to the split. I used it both as a pull- to draw the rim edges past each other right up to the valve stem hole, and a push-to force the rim back out once the tire/tube/flap was in place. But, the final push was done with the 2 wood half-rounds and the hydraulic jack. The lube/grease on the flap was a big help as it made everything slide nicely.
Dick: I don't have a rim spreader but I have read on this forum that you have to be very careful not to distort the rim when using it. The turnbuckle fits to the 2 lugs close to the split so there is little chance of bending the rim. You collapse it only a few inches, up to the valve stem hole. I used the wood half-round system I saw on the forum a couple years ago [I think]. The wood pushes against a very large part of the rim so no one spot is overly stressed. I used 2x6 so the area is big. Anyway, it work very well which is the real test. Good luck with your wheels. Bill
What size of turnbuckle did you use?
I picked up an eight inch one the other day at Home Depot. Funny thing is that nobody in the store knew what a turnbuckle was. Finally found one mixed in with some of their hardware. That was the largest one I could find. I will need to use some chain and a S hook on one end to make it work. This cheap Chinese junk is rated at 350 lbs. Hopefully, that will be enough to get the rim to separate from the tire.
Anyone know where I can find a large turnbuckle at? Something in the order of 12 inch or more.
Bill, thanks for that information on the rim spreader, I used one many years ago and it seemed to work fine. Of course the rim was younger then too and might have been in better condition. If you are near to a Farm Fleet store they would have the turnbuckles I'm sure otherwise a real Hardware store would have them. Depends what part of the country you live in. We have a recycled building materials place here that occasionaly has stuff like that too.
i live in France, i have difficulties to translate all this message to mount tire on split rim.
Is someone could add drawing or photos to see the turnbuckle (i can't translate) and to see how use this tool on rim ?
tahnks in advance

thanks to this answer, and the answer received on my mail, i have discovered what is the turnbuckle.
Tim, thanks to the photo because i would not place correctly the turnbucklet without the photo
