The wheels you talk about are 19" forged alloy wheels made specifically for Morgan and knows as Aeromax wheels. They are eye-wateringly expensive, very light and incredibly robust. I do not know of anyone who has bent or distorted by hitting a pothole.

I have been told that Rays will supply the 18" version to distributors, but not the 19" version: it exclusive to MMC.,
Further, MMC don't seem interested in sourcing or selling these wheels anymore.

I have them on my Plus 8.... happy3
