I don't really understand what your asking, so you want to use 4 straps and 2 ratchets? the best option for car tie downs is to go over each tire with a strap. Thomas C. Sunday auto transport sells car straps that they designed themselves that goes over the tire hooks on both sides of the tire and then the ratchet is out in front or behind the car so the ratchet does not touch the car in any way. You can contact them. I'm pretty sure they sell them. What your wanting to do if I'm reading it right does not sound safe. You should have 4 tie down points on every vehicle according to the FMCSA rule book on tie downs. The law can very well right a ticket for insecured load, and you don't want to deal with that. if the vehicle articulates or bends in the middle it is required to have 4 tie down points on each section of the machine or vehicle. also keep in mind that if you use 2 straps and one breaks in transit and you don't catch it in time, it could result in severe damage to the vehicle or even an accident if a broken strap get caught under a tire at highway speeds.
Not trying to detear you from making this, but I know from personal experience that the DOT for "EVERY" state is pushing real hard, these states are severely broke and they are using the trucks as sources of income. I know also in my area they are focusing on smaller contractors and guys pulling trailers for insecured loads because there clueless on how to tie down and there not doing it safe and the roll with either loose chains and straps, or no chains or straps. Or there getting them for weight rating on tiedown equipment. I know in canada it is required by law to have the weight stamped on the tiedown device, straps to be labeled, chains must be G70 rated and binders must have a rating as well and it better be high enough for what your doing with it. The same applies in the states for chains and binder, not so much straps. Straps in the states can not be frayed or ripped more the 25% of the way through, example a 4 inch strap can not have more the a 1 inch long rip in it. chains can not be rubbed or worn down on the links.
Sorry for the long post, I just want you to be aware of whats going on. If you are not sure of the securement laws you should visit the FMCSA website and read up. I know a lot of guys that say......ahhh there not looking for me, there looking at truckers. Thats not true, were out there doing our job everyday and they know that majority of the people pulling small trailers with cars and equipment don't have near the background that we do, so they are focusing more on them. Good luck with your venture, and what ever you decide make sure its safe, remember your not the only one on the road and in the event of ANY accident the largest majority of them can be prevented, and you can never over secure a load but its simple to undersecure it.
