Cayenne 3.6ltr petrol 2008 - What tyres?????

[97BlackC5]

I've been running Pirelli P Zero's on my Cayenne for years & am looking to change all four in the near future. I've been looking around & supply / fit for the Pirelli's is not far short of £900. Yokohama seem to be slightly cheaper around £790 however I can get a full set of Kumho tyres supplied & fitted for £650.

What would you do....? Porsche OEM fitted Pirelli & (I think) on occasions Yokohama but Pirelli vs Kumho I can save nearly £300.......
