You might re-read that. It says:Federal Motor Carriers Safety Regulations 393.108 (synthetic webbing yield strength).through 398.116
Actually the reg was updated some years ago, but, as usual, it's at the enforcement officers descretion.... It's not thickness, it's width.
Note that in the table further down, it lists synthetic webbing from 1 3/4" to 4" in width:https://www.fmcsa.dot.gov/regulations/title49/section/393.108 said:(b) The working load limits of tiedowns may be determined by using either the tiedown manufacturer's markings or by using the tables in this section. The working load limits listed in the tables are to be used when the tiedown material is not marked by the manufacturer with the working load limit. Tiedown materials which are marked by the manufacturer with working load limits that differ from the tables, shall be considered to have a working load limit equal to the value for which they are marked

Width mm (inches) - WLL kg (pounds)
45MM (1 3/4") - 790KG (1,750#)
50MM (2") - 910KG (2,000#)
75MM (3") - 1,360KG (3,000#)
100MM (4") - 1,810KG (4,000#)
So, as long as the straps are tagged with their WLL, that table does not apply. If they are not tagged, its like with untagged chain which goes off of the Grade 30 chart for WLL.
