Yes, in my head!
It's simple, get the size and type chain you want to use, 1/4" proof coil is probably good for what you need.
cut 2 lengths that will make a circle the diameter of the tire sidewall about 1/2 way between the rim and OD of the tire ( add several extra inches as a buffer for now )
Measure across the width of the tire to get the length of chain you need to reach across the tread to connect the 2 side loops together at about 1/2 way up the sidewall.
Lay the 2 long sections on the floor the distance apart that you cut the cross chains.
Now weld the last link at the end of each cross chain to a link on the side chains, putting a cross chain every 8-12" apart, depending on the diameter of your tire and how close you want the chains. ( the more the better, but you can use up a lot of chain by putting too many! )
You are trying to essentially build a ladder made out of chain.
Leave the last cross chain about 12" from the end for now.
lay the chain ladder on the ground and drive the tractor onto it.
wrap the chains up over the tire and pull the ends together to determine the final length you want.
Use 2 threaded chain quick links to attach the chains together at the length that fits well.
You can either cut off the extra chain or just secure it to the rest of the outer rings, incase you ever want to use them on a bigger tire.
Lastly criss cross some bungee cords on the outside and use 4 shorter bungee cords on the inside and connect sections 1/4 of the diameter along the leaving clearance for the axle etc.
If you really want to get fancy, rather than welding the cross chains to the 2 long chains, put a cut in the end links of the cross chains, twist them open and hook them onto the side chains, bend them closed and weld your cut mark closed. This gives the chain a little more flexibility at the joints.
You can also use 1/4" proof chain for the side loops and use that twisted link chain for a more aggressive cross chain.
