Same here, as that's the recommended manufacturers practice for the x-chocks as copied from their website. I put rubber chocks in front of the front tires and behind the rear tires.

NOTE: BAL's chocks are designed for locking trailer tires when camping. They should be put in place after disconnecting from your tow vehicle and after putting down your stabilizing jacks. They should be removed prior to hooking up to your tow vehicle. Failure to do so may damage your chocks. To avoid undesired trailer movement when disconnecting or hooking up to your tow vehicle, a tire "wedge" should be firmly placed behind one, or preferably both rear trailer tires.
