Looking for information, specifically the width and backspace of the 16" (8 bolt) split wheels fitted to 1.5 ton Australian Chevrolet trucks between the years 1940-1945. The posting below is from February 4th. Thank you.

I know you've already asked these questions repeatedly before, so I'm not sure what further information you are expecting..
![]() The 30Cwt CMP , MCP and 1533X2 trucks are all standard Canadian designs and the 16" rim is the the common 16x6.0 design used by the WD/DND (ie Universal to Ford, Chev, Morris, Bedford), not just Australian trucks. |

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...

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

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

Regarding the 6 stud wheels used by the HUP and now I learn also by the Dodge axles of RHD drive Canadian made trucks.
There are some slight differences wed have observed..... the six stud wheels MUST have a different taper than a regular CMP 8 bolts version......as the 900x16 tires do slip down easier than the 5 degree C15a rims. The six stud wheels/rims I have seen all have the Kelsey-Hayes stamping which includes the date of manufacturing. It also seems from comparing GM parts listing that the early first 200 Lynx Mk I also shared the six stud brake drum on the front axle. Comments????

Thanks Tony for clearly highlighting the differences of the six bolt rim.

The famous Australian rim was therefore an 18 inch rim of similar concept/design made by stamping two halves in 1/4 inch steel plate.
Do we know who made them??? and probably sourced in Australia. Were they stamped by the maker like the Kelsey-Hayse rims. Second question.... concerning the origin of the brake drum posted last in Hanno's posting........... I have a similar picture taken from the wrecks of North Africa...... attached...... from the picture I have concluded that it is a Chevrolet chassis from the cleanly sand blasted sheet metal, indentation on the frame for locating a LHD steering box and the spring layout. The fender seems to indicate an earlier version of LRDG using a 38-39 or 1940 round fender model....... Does any one have a larger picture depicting that same vehicle but in larger format showing the cab style. So far I have not been able to find any references in GM part manuals for that elusive riveted brake drum and I have many....... Thanks Bob C.

Canadian Built Ford, Chev and Dodge vehicles have the mountings for both RHD and LHD steering boxes on the chassis, even the CMP, although no-one has ever forund a LHD steering box that will fit a CMP chassis! |

Hanno,
I haven't measured the two types of Canadian 16" rims to confirm actual size and shape but what you are saying ("The six-stud CMP wheel was used on 8-cwt trucks. It doesn’t have a different bead taper, it simply has a smaller diameter") is in conflict with the AEDB design record that states the rim for use with 9.25-16 tires has a 5 degree rim base taper and the rim for use with 9.00-16 and 10.50-16 tires has a 1-1/2 degree taper. The AEDB record doesn't give a diameter at the bead seat other than the nominal 16". Mike's measurements (taken from tires) show both a smaller diameter and a greater taper (assuming the tire wall was of similar thickness at the bead seat) for tires intended for use with the "American" rim. |

It actually HAS BOTH.

I made that remark as most people think only the rim base taper is different, which isn't true - see Tony's remark below. A 3.5 degree difference in rim base taper would go unnoticed when fitting a tyre. A larger rim diameter does. Thanks for clearing that up, Tony. Hanno
