So I have been looking at videos, and pictures of the installation of wheel adaptors and started noticing that all the hubs are flat. Well mine are not, and I want to make sure that they will work and be safe before purchasing any. Dont think this makes a diffrence but currently my trailer hub is 6x5.5 and converting to 6x5.31. Here are a few pics below. Also trying to figure out would my trailer be Hub centric or Lug centric?
