16" 8 bolt Split Rims for 1.5 ton Australian Chevrolet Trucks

[Philippe Jeanneau]

Indeed I have, but I have only obtained some of the information, so I hope that if I keep asking someone else might pick up the fact that the backspace on these wheels is still a mystery... Mind you, I have asked for the backspace and not the offset...

[Andrew H.]

What do you mean by "back space" and "off-set"? These are not terms I am familiar with.

Here is the definition explained

Does this photo help? These are the 16-inch split-rim wheels on our LRDG 1533X2 truck.

[Philippe Jeanneau]

It sure does... I imagine that the wider half of the wheel fits against the hub? and if you were to place a straight edge on that side and measure the distance to the center it would be about 4.00"? Are they original to your vehicle? if not, what do they fit originally?

Hi Philippe,

Using Lang's link definition on my Ford Kelsey 16" CMP wheels the setback is 4-1/4" (108 mm) as measured.

A bit of parallax in the photo but when I got down to the level to the wheel the measurement to the bottom of the angle iron from the mounting flange is 4-1/4"

Hope this helps.

Cheers,

Philippe,
You may not know this but ALL these British style MOD split rim 16" wheels, whether British, Canadian or Australian (though I think they were made in Canada?) have exactly the same dimensions and are fully interchangeable between vehicles regardless of tire size. The same with the 20" ones except that there were two styles of them - 8 stud dished centre ( used on 3 ton trucks) and 10 stud flat centre (used on Scammells and Matadors etc)

The British ones have BSW threaded studs vs the American threads on the Canadian ones and for some strange reason the valve cut out is in a slightly different position which prevents mixing front and back halves but as assemblies they are the same.

The only exception to this that I know of is the six stud version used on Dodge D212 and Chevy Heavy Utilities. I believe but am not certain that these used the same pressings as the 8 stud ones. Could someone confirm or correct that please.

David
