I remember the dealer twisted my chains because they were too long. My neighbor who is quite experienced with tooling and metals warned me that twisting was detrimental to the chains.
What I did was to move the clip hooks a few links down the chain. This effectively took care of the excess chain. I then tie wrapped the links that I had bypassed back onto chain behind the clip hook. This keeps the excess from dragging and has no detrimental effect on the movement of the chains. Easy to move that clip hook, and if you change tow vehicles and need more chain length, it's easy to move the clip hooks more towards the end of the chain.
