The 16s on my Mini are the first set of RFTs i have ever had, all my previous cars, BMWs included, have had any RFT swapped for normal tyres. TBH, with all the hype around how harsh RFTs ride, having just driven 800km across the country in the car, It rides no differently to any other car with similar size tyres. The bigger sidewall likely makes a difference, I can imagine a stiff sidewall RFT on 18s or 19s could be quite harsh, but Im still not convinced that they are the devil like the internet tries to tell me.
