I have a set of 18" Apex PS7's that match the OEM ZCP rim WIDTHs (9" fr, 10" rear staggered rim widths) with RE71R 275/35/18 square. Fronts are rubbing slights on the struts under very heavy cornering loads. Will be adding 5mm spacers and this will definitely provide sufficient clearance. Rears clear without spacers.
I am also running the Pzero OEM sizes on the ZCP 19" wheels and will be changing those out to Pzero 275 fr and 295/30/19 rear.
HOWEVER - There are many versions of the Pzero 295/30/19 on Tire Rack.
295/30ZR19 100Y XL Sect 11.6", Tread 11.5"
R01 Audi
295/30ZR19 100Y XL Sect 11.6", Tread NA (does anyone know the tread width?) i.e. Will these fit without rubbing?
N2 Porsche
295/30ZR19 100Y XL Sect 11.9", Tread 11.7"
(Assume this is the tire you refer to in the above post as viable on ZCP rim)
295/30ZR19 100Y XL Sect 11.9", Tread 12.5"
(Assume that these will rub)
Anyone know how this tire is so much more tread on the ground?
BMW
295/35ZR19 104Y XL Sect NA, Tread 9.9"
Due to the reduction in tread wouldn't want these anyway but assume these are too tall AND also may rub
Any advice is greatly appreciated.

Once again, yes you can fit a 275/295 setup on the OEM ZCP wheels its just not going to be optimal. You don't want to run a 295/35/19 those are way to tall at over 27". IMHO, I wouldn't go beyond a GTS setup on the OEM ZCP wheels. You can run the Pirelli PZero which they have in GTS sizes. I moved on from the ZCP wheels and I am now running VMR V810 flowformed wheels in 19X10 and 19X11 with 275/30/19 front and 295/30/19 rear and I can't tell you on how planted the car feels even over my GTS setup.
