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

[Tony Smith]

ONLY the GM/H assembled vehicles has the 18" wheels with a 10 x 7.25 bolt circle and 12 dividing rim bolts. I have not seen a chassis code for these vehicles, but they are not completely manufactured by GM/H. The chassis and major components were sourced from GM Canada, with local items like the cabs and wheels made here. As their payload rating is the same as the 1543X2, but assembled here, the code may well be something like 1543X4 (X4 for Australian assembly).

Hi Tony

I see we are reading from the same Chevrolet army parts book.........

This has me puzzled....... the parts list only references * indicating 32x6 tires or X indicating 10:50 x 16 tires........ from what you are saying it seems to indicate they were fitted with 18 x 10:50 tires/rims when re-asssembled in the UK for Poland or Australia.

So complicated.

The black and white "Factory" pics are at Oshawa, so there was no change to the vehicle on arrival at it's destination. The X2 indicates it's destination, or perhaps it's contract. I wish David Hayward was here to explain in his rambling way the oddities of Chevrolet contracts because they really are a confusing mess.

Gimme a Ford anyday.

Trying to make this a reality... So far I have the following information on the original Canadian 16" wheel:

Rim Size: 16"
Width: To be determined...
Backspace: 4-7/8

Bolt Pattern: 10 x 7.25"
Flange thickness: 19/64" chamfered for wheel nuts.

Hub wheel Studs: 9/16"-18
Bolt hole: 19/32" straight cut.
Pilot Hole: 4.75"

Joining bolts: (8) 7/8-14 UNF

Backspace: 4-7/8”
Outer half: 3-15/16"

The new wheel (minus the stem valve protector) would have different backspaces front and rear and be wider (at least 8") to fit the U.S. spec. 1.5 trucks...

No such thing.

The 16" rims were made in Canada and were 6" wide.

The only Australian-specific wheels were 18".

Thank you for the correction and information... Were the 18" 10x7.25 (10 bolt) Australian wheels 6" wide also?

Why is it so difficult to find the right information or photographs? I have been told that the width of these wheels is anywhere from 6", 6-1/2" and even 7" wide...

But does anyone even know how to measure the width of a wheel correctly? Something so simple doesn't have to be so bloody complicated!

If someone has the correct information with supporting evidence please post it- all the information!... I am sure many will find it useful.

X2 stands for "export to UK (bult-up)" - see David's list on this thread:
