The tongue weight rule of thumb of 10-15% of the load weight was developed by trial and error over many years using a variety of non-optimal towing solutions. It is not a hard rule of physics that stability requires 10-12% tongue weight.What is the minimum tongue weight? What Is Proper Tongue Weight?
For conventional trailers with ball-mounted hitches, proper tongue weight is roughly 10 to 15 percent of the total loaded trailer weight.
GMC Life - Tongue Weight Is Key To Safe Towing

The Cybertruck chassis will be very rigid in contrast to typical trucks that have a ladder frame and are essentially a giant spring when loaded near capacity. The springiness of a ladder frame is what has caused many experienced tow drivers to recommend such high tongue weights. The Cybertruck will likely tow beautifully with 7-8% tongue weight. Some testing may be required at lower tongue weights to determine the limiting factors.
I don't think this has a lot of importance to this particular application, but I wanted to broach the subject so people can realize that the Cybertruck will have very different (better) tow dynamics from traditional trucks with springy ladder frames.
