Looking at car hauler/trailer, need some dimensions, please.

Putting aftermarket wheels on a trailer can be a bit dicey, in my experience I make sure of the wheel weight rating. I've used mostly steel wheels instead of aluminum because of the side stresses put on the wheels when turning the trailer.
I had 2-1/2 hours of windshield time to think about those wheels as I was driving home, but I hadn't considered side stresses. I'm sure they worked just fine for the PO, who used it strictly for his open wheel car, but I may be using this for things a bit heavier....

(Hmmmm. I wonder what I can get for those Lincoln wheels on CL? :) )
