I thought bare minimum was 4 chains on the corners?
I take that to mean two ties downs at the front and two at the rear.Automobiles, light trucks, and vans must be restrained at both the front and rear to prevent lateral, forward, rearward, and vertical movement using a minimum of two tiedowns.
Issue 4: & sect;393.106(d) - Determining the aggregate working load limits for tiedowns.
Agency Policy: The aggregate working load limit of tiedowns used to secure an article or group of articles against movement must be at least one-half times the weight of the article or group of articles. The aggregate working load limit is the sum of:
1. One-half the working load limit of each tiedown that goes from an anchor point on the vehicle to an attachment point on an article of cargo; and
2. The working load limit for each tiedown that goes from an anchor point on the vehicle, through, over or around the cargo and then attaches to another anchor point on the vehicle.
BTW, 2" nylon straps have a working load limit (WLL) of 2000 pounds. 4" straps are rated at 4000#.

That may be a good rule in general but my 2 inch straps have a tag that says 3300 pound working load limit. That is probably what the DOT will be looking for if I ever get stopped.
One could argue over your statement, "Although it does not legally apply to non commercial use, it is a good guideline."The Federal requirements for commercial interstate tie downs can be read at
Cargo Securement Rules - Federal Motor Carrier Safety Administration
Although it does not legally apply to non commercial use, it is a good guideline.
