I use E-track and 4 over-the-wheel tie downs on my trailer. I love it. They go on each tire fairly quickly, once you have the routine down. I marked where to install the clips in the E-track at each wheel, so I don't have to "figure it out" each time.
My E-track is welded to my trailer frame, not just screwed into the floor. The floor was put in after the E-track, back when the trailer was made.
I added an additional E-track clip to each of my wheel tie-downs on the strap between the tire and the ratchet mechanism. The ratchet actually lays flat on the trailer floor and then the strap goes up from the attachment point (clip) I added and over the tire. I was inspired by a professional car hauler that I saw securing a car this way.
I have attached a picture showing how this is done on the rear wheels of my '63 Riviera. It works the same on a Model A. It's kind of hard to see, but there is an E-track clip up near the tire and the strap goes through that and then up from there. The ratchet is not at an angle up to the tire. Much easier to work with and adjust, and does not interfere with car fender, bumper, etc.
