Trailer set-up , need correct terminology for the inset wheel pictured below

[againstthegrain]

What's the correct way to describe the inset wheel design in the trailer?














For reference the 2nd trailer has the more typical setup.

In aviation, we call them each a "bogey."

Well, the first one is a tandem and the second one is called a dually. The first one has four wheels on the trailer and the second one has eight wheels, which is why the outside wheels stick out farther.

Is that what you're asking?

Both trailers are called tandem axle.
The top trailer is an eight and a half foot wide version.
The bottom one is seven foot wide.
If there's any official jargon for the fender location, I've never heard it.

The 8' 1/2 foot versions force that change automatically. Thanks.

Yep. They have to in order to not exceed the maximum width requirements. If they moved the axle and fenders outward, they'd have to shrink the inside dimensions which would defeat the most common purpose of the trailer. (hauling an automobile in it).

Maybe they are described as internal wheel trailer or an inboard wheel trailer. The alternative being an outboard wheel trailer?

Flush mount?

Thanks, the normal case for the inset, inboard, or internal wheels is a function of the maximum legal width (w/out special permits) which is an 8.5' width trailer, typically a car hauler. I'm presuming inset wheels are only used when it's an 8.5' width trailer making knowing nomenclature not pertinent to my needs in a cargo trailer. Trailers narrower than 8.5' will typically have the outset or outboard wheels and that's what I'm going to buy despite liking the appearance of the inset wheels better.

Tandem axle trailer - trailers w 2 axles
Dually - refers to 4 wheels and tires on 1 axle on a tow vehicle


Your eight wheel comment - we'll let that slide.
