I'm running a set of OEM Style 516 20" wheels from an LR4 XXV Edition wrapped in LT265/60R20 Falken Wildpeak AT3Ws. These wheels were standard on the 2014 LR4 XXV Edition, which was limited to 225 units for the North American market. Luckily all XXV Editions came with the HD pack giving you the two-speed transfer case, rear diff lock and a full-size spare, so I got five wheels. These wheels were also available as a dealer-installed accessory for the 2015MY. I wouldn't be surprised if I have the only Defender on the planet with this wheel setup.
