The ride will be very slightly harder & slightly noisy with 21" wheels. But if you settle for 20" just for these issues, then it wont be much better than 21".

I would go with 18 or 19 for ride comfort & less noise. However, if I am going with the lower profile, then I would go all the way & get 21".

Also of you get PASM, the ride comfort issue with the 21" is sorted out to some extent.

Furthermore, if you want a sporty ride, remember the width of the 21" is 295, 20" is 275 and so on....so the bigger wheels will give you more contact with the road hence better handling but also slightly more noise and slightly more sensitive to road conditions.

Ultimately, I think decision will be based on personal priorities between look, comfort, sportiness/handling and of course cost (initial cost as well as tyre replacement cost due to usage/age or flat tyre).

Hope this helps

Thanks

It's the noise/thermal insulating glass - factory option.

Also keeps the interior much cooler than the tints.

nice, congrats
