I tie down using the axles.
Usually two straps at the front (I'm more concerned about the vehicle falling off the back of the trailer) and at least one at the rear.
The Father-in-law has the correct straps for tie down using the wheels which I use on his trailer.
Make sure everything is bolted firmly in place before towing. The picture below shows a 2a GS, as we were coming across the Westgate Bridge my son looked behind us and pointed out that the roof was lifting off ! Turned out there were only a couple of bolts holding it in place and a couple had fallen out on the way from Geelong.
