Outboard vs Inboard Wheels

[AriMB]

Just to get some definitions straight:

@F3LINE

Inboard wheels are within a rail of the frame, whereas outboard wheels have nothing between them and the bumpers.

What you’re calling “outboard wheels” are usually referred to as “cantilevered wheels” because they are cantilevered off the drive tube. What you’re calling “inboard wheels” are known by a number of different names, but your best bet is probably “non-cantilevered wheels”.

I seemed to have interpreted the question differently.
first off: both examples are WCD. WCD is generally defined as a traction drivetrain with the center wheel dropped.

@EricH

The “standard” definition of a WCD is a 6WD drop-center, cantilevered wheels, live-axle, center directly driven off of the gearbox (usually a 2-speed gearbox), outside wheels chain-driven off the center axle.

Over the years the definition has gotten looser (no longer usually 2-speed gearbox, can use belts instead of chain). But cantilevered wheels is still definitely a requirement.
