that is NOT off the RV in question anon
PERIOD
the Hub is ALL WRONG
that should be a basic DRUM BRAKE hub
the hexagonal looking device between the hub and the broken section of axle is something I have never seen before
it is POTENTIALLY part of an electric HUB MOTOR that was driving that wheel
making this from an electric vehicle of some sort
the AXLE is about 3-4 larger in DIAMETER than the hub axle SHOULD be for that type of vehicle
it SHOULD be a SOLID STEEL axle, about 1.25 - 1.5 inches in diameter
that axle looks aluminum
its about 6 inches + in diameter
and its hollow
I have NEVER seen that before at the hub in any vehicle I have worked on (MechanicFag)
The Tire has NO TREAD
that is NOT a DOT legal tire for STREET use
it ALMOST looks like a racing tire
a Drag Radial
or a Circle Track Slick
but I doubt that
it is pobably something Commercial/ Industrial
for moving BIG/ HEAVY shit
