As others have mentioned the chains are on wrong, the open side of the cross chains needs to be facing out from the tire.
Also they are not squared up on the tire. As you try and tighten them up you'll need to keep every thing even and square.
That style of chain will never ride smooth. If you are pulling hard at a slow speed you will see the tire slip/spin each time it rolls around to an open spot on the tire.
As far as mounting the chains, if you are picking them up and draping them over the tire then driveing ahead a bit and trying to fasten them you are just beating yourself up.
Lay the chains out behind your tractor with the traction side up,
get a 5-6 foot long piece of rope or cord,
tie it to the outside chains, often I'll use my latchs,
with the rope forming a V loop it over a couple of tire lugs.
drive ahead with the rope pulling your chains up and around your tire.
Straighten and even your chains as you drive them on ,
once you have made a complete revolution with your tires your hooks are facing up and your connecting links are hanging down.
Fasten your chains. When you finish you need to have the same spacing on the fastening links on both sides so your chains are on square, if not square you will be fighting them constantly.
Here is a link to some pictures showing this method;
