On a SRW your GAWR is based on tire capacity.
Most 1 ton SRW and DRW use the same axle but the DRW has a much higher GAWR because of 4 tires.
So say your SRW tires are rated at 3200 ea, your GAWR is 6400 lbs on the same axle that may be rated for 9k lbs on a DRW.
If you upgrade your tires to 4K lbs ea, technically your GAWR would be 8k lbs or whatever your axle is rated for.
These numbers come from the truck manufacture but if you want the actual axle rating check the axle manufacture for what they designed it for.
You have already mentioned you can't change what the truck is rated for but that seems to be more of a licensing or manufacturer rating.
On the newer 1 ton SRW you can change to a higher weight rated tire and carry more weight, and probably still remain under GVW.
My 16 SRW has a higher GVW by 500 lbs than my 03 DRW had.
