FMCSA reg 49 cfr 571.110 and 571.120 are the regs that ties the vehicle manufactors GAWR (placard) and tires capacity. When we look at S5.1.2 it says "if the tires size designation of the tires fitted to the axle does not appear on the certification lable, the sum shall be not less than the lowest GAWR appearing on the label. The label (door tag) is required per 49 cfr part 657.4 which has the vehicle manufactors GVWR and GAWR. As I stated above my neighbor lady (longhauler/hotshot) came up with that reg as she just tagged her new '07 6.7 Cummins CR 3500 for over 26000 lbs combined.

you are correct. Guess I could have said it a little clearer. My state is required to operate per FMCSA for our commercial operators. But we do use those placard (door tag) GVWR and GAWR and tires capacity for non commercial weight capacities. 49 cfr part 571.3 gives us our definitions of GVWR/GAWR.
I had the very same thing happen on one of the companies we sub contracted through GNs flatbed. TX DOT crawled under the trailer and got the axle capacity from the axles. He added both axle numbers and I was just under. His comment was I was lucky. If he hadn't found those axle tags it meant impounding till I came up with some GVWR tag or axle tags from the axle manufactor.

those big numbers are max loads. Our size trucks come under those regs for over 10000 lb GVWR and 10000 GVWR and under such as 571.110 and 571.120 regs. Look at 49 cfr 571.3 gives us the definitions of GAWR/GVWR/GCWR. It states that GAWR is the vehicle manufactor rating per door placard.
Think about it. If we are using a 3500 DRW truck with a 12000 GVWR and are going to haul commercial with a trailer we are required to tag the combination (truck/trailer) for the trucks 12000 GVWR and the trailers 16000 GVWR. Add those together (28000 lb) will be what you are tagged to haul. GVWR comes from the trucks door tag and the trailers GVWR comes from its placard. To balance the load on the truck we go to FAWR/RAWR which is on the door tag. Both are required by FMCSA. The regs are there and they have to be dug out and the most important part is finding how they are interpeted and enforced.
