That's if the chain breaks and gets dragged between the wheel and caliper, the damage will be significant. That was the comment for - didn't elaborate, but here it is: When I had the 16" wheels (winters), the city guys throw gravel on the icy roads. The gravel is small, but every now and then I had a pebble getting behind the wheel. It scored badly the wheel & the calipers - they got crushed. A broken chain will not get crushed if it gets there - it will do big time damage. Again, on 16" the clearance is very small behind the wheel. On bigger wheels, the width of the tire is larger, and depending on your setup (ie: sport, staggered, etc), the clearance of the rubber part against the fender wall is small. A broken chain will shred/tore the plastic and the sheet metal. A better solution would be the "socks" or the nylon "chains". Even if these break, they will not inflict damage. I have seen the damage done by a broken snow chain and it's ugly. The wheel will spin a few times before you can stop safely - by that time it's bodyshop appointment chore.
