4WD system explanation

Can anyone help. I have ordered the 19 inch style 5 wheels. We get the 18 inch spare wheel in Australia as standard. With my current Subaru Forester, it is advised that you can only use a spare that has the same rolling circumference as the other wheels. In the event that you use difference size wheels it adversely effects the diffs and AWD system.

With the RRE I have calculated the rolling circumference of the 19 inc wheel and the spare. As you can see there is a difference in the rolling circumference of 62 mm.

Can the Land rover experts explain why this does not effect the diff’s and 4 wd system?

Here is a link that compares the Subaru AWD system to Honda, Toyota and VW.
