I've now bought a second set of 18" alloys from an Evoque with virtually brand new Pirelli tyres on them for less than I can buy the four tyres, bargain!
Now it's a choice of which set of alloys I prefer before selling the other set.

yes, as a general rule discovery sport / freelander /evoque wheels are interchangeable -though some have different offsets as below.
I think the bigger the offset (ET45 number), then the closer the wheel sits to the car, the samller the number the further it sticks out.

May be wrong - am no expert though
