track width vs overall width?

[gregor]

do I have this right.

Track width ( as advertised by a manufacturer ) is from the center of a tire to the center of the other tire, right?

Not measured from the outside of the tires

Overall width is a exterior dimensions, right?

[Chris_A]

Correct.

To further confuse things there is also the WMS-to-WMS measurement. WMS is the wheel mount surface.

WMS is fixed for given axle configuration. Overall width and track width can change with different wheel backspace/offset.

thank you.

[PMcD]

Yes, and wheelbase is measured from the centre of the front wheel to the centre of the rear wheel on the same side of the car.

someone doing an alignment? the old fashion way?

[gregor]

nah nothin like that. Was just checking to make sure I was getting a Uhaul trailer wide enough to pick up a car.

The usual restrictor on a trailer is the car body width. The fenders can be very hard on fender flares and such.
