I'm looking for a full set for the E39 - pretty sure it's 235/45/17 front and 255/40/17 rear but if anyone can confirm that for sure I'd appreciate it.

Any comments on Dunlop Sp Sport Maxx MFS? I've been quoted €490 for a set fitted and balanced.

I was also considering high quality part-worns (Michelin etc) but I'd prefer a matching set and that'd be hard to find. Maybe not necessary. Any suggestions?
