I've thousand comments of people said that how happy they are when change from RTF to NonRFT Michelin PS4S and actually I'm consider, too.
But one thing that no one mention is change Tire and/or from 20 inch wheel to the same size, or lower it to 19inch?

I'm not sure which makes the most effect to ride smooth and quietness, change NonRFT or lower wheel size to 19 inch.

Appreciate for everyone's experiences.
So going to 19 will give you more sidewall and slightly increased comfort because of it. I've swapped between my stock 19s and 20s a few times and I personally enjoyed the ride on the 20s but that was because my 20s were Ps4S Non RFT and my 19s were stock RFTs.

It's very negligible on the 7. I'd go up a size if it were me for the aesthetic purpose as it matches best with the big body of the 7. 21s look amazing but comfort will suffer a little when compared to 19 and 20.

Thank you for your reply.
I will try changing to NonRFT first and see what happen, and then lower to 19" if needed.
Not sure if I will do both at the same time tbh 😄

I can confirm I'm running Michelin PS4S on my 17 750i with m sport 20 inch wheels. Truly I feel that the tires transformed the whole car. The ride is much more balanced, dynamic, sporty, and even more comfortable, etc.

Thank you so much, now I have more confidence to change to normal tire instead of stick to RFT 😄
