From FE's post:
"GTW is what a trailer is supposed to weigh when delivered to the new owner. The CCC placard will list the maximum amount of cargo that can be added to the GTW. When added together those two cannot be more than the vehicle’s GVWR. At that point the only way to find the pin weight is to weigh it. Once the pin weight is deducted from the GTW the remainder - GAW - is what’s being carried by the axles. That weight cannot be more than the GAWR. OE tires must have a total load capacity equal to or greater than GAWR."
According to Dexter Axle:
"The maximum load carrying capacity is limited to the lowest load rating of any individual component selected. For instance, the load rating of a pair of wheels may be lower than the other axle components. If the is the case, the load rating of the total assembly must be reduced accordingly. As a specific example, if a pair of wheels are rated at 1500# each and are use with other components rated at 4000#, the maximum load capacity will be limited to 3000#. If two tires rated at 1400# each and are used on this assembly, then the maximum load carrying capacity is limited to 2800#"
Dexter applications manualIn example from placard you posted, according to Dexter the axles rating are derated to the total of load rating of the tires.
Can you post a reference that OE tires must have a total load capacity equal to or greater than GAWR?
