ok so came across some used original 17" alloys with good tread , the same as my spare at the back, just wondering if being a sport version e53 and the tires being 235/65R17 104H may not be recommended as the original 19" had higher speed and load ratings , these alloys and decent tires on em cost €300 for the set approx $375....
