I’m clueless…
2016 Volvo with meritor MT40-14x drives. The trailer I can get permitted up to 24,000lbs per axle. That’s 72,000 lbs. Only in certain states.

@Sinister is likely a better resource for all his years…
I know this load we permitted me for 46,000 on the drives which sent me into a tissy for finding a new truck. Because I was over 20,000 lbs on each axle on the drives, I had to route myself in such a way I didn’t go through Oklahoma. I was 106k gross.

So there’s no really easy answer to your question. I’m licensed for 80k in some states, 100 in others, still others 113 and 120k.
