These wheels are staggered fitment, therefore the rear wheels are wider than the fronts. BMW Part No: 6 796 265.
Wheels had tyres sized 255 30 20. Came with Pirelli Pzero runflats from BMW.
I changed these for Michelin Pilot Sport 4s in the same sizes (non-run flat initially, then the ZP or zero pressure run flats later on and found these were far less prone to damage on our roads), which gave a much better driving feel than the Pzero run flats. I'd recommend the Michelin PS4s ZP tyres. I have the rim taped with insulation tape for protection whilst storing. Collection only, I have no packaging to allow me to post.
