Those look more a truck rim and tire in the first image. I'd have no reason to doubt it is all from the same incident.
Friend of mine showed me a nice trick when pulling with cables like that, hopefully someone who sees this will prepare and be safer. Take a couple chains and lay out straight along side the cable you are pulling with. Use some quick links, carabiners, zip ties, twine, whatever... just hang the chain from the cable loosely every foot or so, and try to do it the full length of the cable, but at a minimum on both ends. Once you are pulling, if the cable snaps, the weight of the chain and the freeplay in the attachment of the chain keep it from flying around. Of course you want to size your chains accordingly as a light swingset chain wouldn't help much of anything, those guys needed some good heavy logging chains hanging from that cable to prevent that.
A heavy rope wrapped around a chain and tied loose on each vehicle will keep a chain from popping and flying when pulling too.
The key to pulling safely is never pull with anything you don't want flying at you, and if you don't want it flying at you, secure it from flying if it breaks.
I feel bad for his family...
