Tony, welcome to the RF world. 112Hs are excellent machines, but as you noticed you need traction and weight.
The weights should not interfere with the tire chains. The tire chains should only touch the tires. Let some air out of the tires before installing the chains and get them as snug as you can. Then air the tires back up and you can use bungee cords to make an "X" on the outside, across the weights if need be, to keep the chains snug and to keep them from loosing up and falling off.
