hydroplaning

I would suspect that the FAA test numbers do not take power application
into account.  Aircraft wheels are dead drag when they're doing what
they're supposed to do, either free rolling or braking.  I would suspect
that earth bound motor vehicles (except for a rocket car or two) have
very different dynamics when the rubber meets the road,  especially when
power is being applied to all four corners.  That's MHO, I'm not a
scientist and I don't play one on TV.
