I read elsewhere that a RR Sport TDV6 customer was declined by his dealer when he asked to buy the 20" Supercharger wheels. I am also aware that 19" is the largest wheel available on the full size RR and that Land Rover cite "vibration issues" as the reason. At the same time companies like Overfinch and Kahn are happy to fit 22" rims to Diesel RRs and RR Sports. Can anyone explain or elaborate on this vibration thing. The Director of Kahn Design assures me that he is currently driving around in a RR Sport TDV6 on 22s without any problem.
ALSO during an interesting conversation I happened to mention that I had a quote for fitting some 22" Kahns from a company in the south of England at which point Kahns said that they are probably quoting for wheels intended for the X5 which physically fit but have the incorrect offset (apparently ET40). Indeed at the time of writing they don't wholesale their RR offset wheels to other dealers. I'm not sure of the exact implications but anyone thinking of going the larger wheel route needs to be sure they're getting ones with the correct offset (ET55). I see no reason why they would make this up since I was planning on their wheels anyway albeit from one of their dealers.
