Regarding the Security Chain SC1040

1. I presume you put these are your rear tires...correct ?
Don't see how they would work just on the front.
Just making sure they fit the 225/35-19 rear tires.

2. Did you use any kind of keeper ??...similar to these https://goo.gl/IJcwO6
These go on the outside face of the wheel to keep the chains tight.

3. No clearance issues with the wheel well etc. ??
