From what GoWesty states, they've had good luck with this combo, HOWEVER,
all it takes is one extreme failure and someone will own GoWesty due to the
liability he's assumed based on his "explanation".  IMO, that's too great a
risk to take just to sell some tires.

Cheers,

Lucas of GoWesty asserts it tells you that they didn't test it. The fact
that they are applying a "one size fits all, specifics be damned" load
reduction formula indicates this is most probably the case.

>Does GoWesty know more than the tire manufacturer?

In the case of HydroEdge tires on Vanagons, I'd say GoWesty probably does.
As Lucas says, they've got over a million miles logged with those tires
without a single failure. The best test would be true experimental "test to
failure" or "test to maximum possible loading plus [x]%". In the absence of
that, I'd accept continuous long-term real-world usage stats over a
manufacturer's formula-based guess. Tire makers manufacture such a huge
variety of tires that they CAN'T test each individual design, but instead
must make an estimate. The estimate is, of course, invariably conservative
for reasons of liability. With the exception of catastrophic design
screwups (a la Firestone), you can count on everything being fine if you
stay within the rating; But this doesn't mean that all conditions outside
the rating are inherently dangerous.
