HOW TO MEASURE WHEEL OFFSET
The OFFSET of a wheel is MEASURED IN MILLIMETRES and is the distance from the hub mounting surface to the centreline of the wheel .
Video showing how to measure offset ;

Similar to offset , BACKSPACING is the distance from the hub mounting surface to the inside lip of the wheel .

DIFFERENCE BETWEEN THE 10 inch and 12 inch FRONT WHEEL STUB AXLES
The stub axle on the Later Robins with the 12 inch wheels is much larger .
Note that I have fitted a kingpin between the 2 stub axles so that they are retained at the same position .
The stub axle on the right of the photo is the one fitted to the 12 inch wheeled models.
The 12 inch wheel has a much deeper offset and the new stub axle compensated for that .

AXLE ; WHEEL FITTING INFO
QUESTION ; Can you fit the later Robin 12 inch wheels to the Earlier 10 inch axle and vice versa ?
Thanks to Reliant World forum administrator , sparesman2000 , for the following info ;
10 INCH REAR AXLES ;
Can only take 10 inch wheels unless spacers are used with 12 inch WHEELS
12 INCH REAR AXLES; {Mid 1990,s onwards axles which are fitted with the Mini brake system}
Will happily take either 10 or 12 inch wheels

WHEELS ; FITTING LONGER STUDS
Following photos from an Old Reliant World Post
Azzy wrote ;
This is my trick for fitting longer studs, make a hole...
And the stud appears
Azzy said he put a rubber grommet in the hole and it has worked fine
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
FRONT WHEEL SETUP DIFFERENCES BETWEEN 10 INCH WHEELED MODELS AND LATER 12 INCH WHEELED MODELS ARE ;
{ 1 } It has mini brake parts
{ 2 } The stub axle is much bigger on the 12 inch models .
{ 3 } The front hub is the same except for the fact that the part that fits through the centre of the wheel is a different size on the 10 inch compared to the 12 inch wheel .
The 10 inch front hub is wider as is the centre hole on the 10 inch wheel .
The 10 inch front hub will not fit through the smaller centre hole on the 12 inch wheel .
The 10 inch front hub can be modified very easily to fit through the hole in the 12 inch wheel .
.
The 12 inch front hub fits either wheel but note the following ;
{ 4 } The 10 inch wheel has a shallower offset compared to the 12 inch wheel .
{ 5 } The nuts to secure the wheels are different on the 10 inch and 12 inch wheels
