How is a vehicle's GVWR determined and why is it lower than the axle ratings?
Consider the Ford F350 as an example. The 08 F350 SRW Long Bed has a GVWR of 11500. The combined axle ratings are 13000lb (front 6000 and rear 7000). If you subtract the base curb weight of 7773 (front 4765 and rear 3008) you get a delta of 5227 (front 1235 and rear 3992).
The published payload is 3640 lbs. So what happened to the 1587 lbs? The OEM 18" wheel/tire setups are rated for about 3500 per wheel/tire so they are not the limiting factor. Frame, brakes, etc. must play a role. Can anyone shed light on this one?
I'm considering the merits of a beefed up F350 vs. a SRW-conversion of a F550.
