Compared to your existing wheel, this new wheel will have an inner rim which is 41.3mm closer to the suspension strut. The outer rim will poke out 66.7mm less than before.
The strut shown in the diagram is for show only. Don't worry if the wheel looks like it fouls!
Bear in mind most tyre manufacturers vary slighty from the specs, and that it could be dangerous to run tyres on wheels they aren't designed to fit.
