Compared to your existing wheel, this new wheel will have an inner rim which is the same distance from the suspension strut as your current wheel. The outer rim will poke out the same as before.

Wheel Fitment Guide

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.
