Have to disagree Flatman5. No sign of any degradation in ride comfort & quality with the 20” (and I have test driven 19s). I think they both look very good and would have been happy with 19s, but the 20s look a tad better (IMHO again) and just fill the wheel arch that little bit more!

I think we will all be happy with either option.
Pjm just my view obviously, think we will both be very happy with our choices, it’s a fantastic car to drive hope you enjoy yours too👍🏻

I ordered the 18' Inscription 'standard' wheels because of ride confort with the 4C adaptive suspension. What disadvantage might I have having smaller wheels ? I am concerned about my choice now ....

Don’t think you will have any disadvantage. Possibly an even better ride! 4C I am sure will be good - couldn’t get it with the FE.
It was an XC40 FE D4 AWD Auto - Bursting Blue/Charcoal/20". On the road since March 9th. Sold on August 20th. It was Polestarred. :)

Very basic description, but:

Smaller wheel = bigger tyre
Bigger wheel = smaller tyre

A smaller wheel/bigger tyre combo is going to put more air between the road and the alloy wheel, this is going to smooth out road imperfections and bumps. The fact there is more air between the wheel and the road means that air in the tyre is going to absorb more of the energy from the bumps, isolating them from the rest of the car. However, in situations where you are cornering fast you are likely to feel more 'wallow', and you'll get less feedback on what is happening between the road and the tyre, e.g. did it just slide a little or did you imagine it?

A Bigger wheel/smaller tyre combo is going to allow you to 'feel' the road better, giving you more feedback on what is happening both with the surface of the road and the results of your steering inputs. This will be an advantage going round the bends, especially if going fast, the car will feel like it is holding the road much firmer, and you will be much more aware if the car starts to slide. The down side is that the ride is likely to be much firmer and, although others on here say they didn't notice any difference, you are likely to feel more from bumps and potholes you hit.

Give me a small wheel/big tyre combo anytime, comfort over looks wins for me. If the FE was available with an 18" wheel I'd have gone for that option.

Are they wider? I thought they were the same width. I expect a wider wheel will give more 'cushioning' as there'll be more air in the tyre to absorb the road imperfections. However, I don't think it would be as noticeable as the difference between wheel sizes.

Tx for the explanation ! I am reassured having made the right choice. Comfort is prime for me !

Sad (!?) but very useful indeed! :D

So sacrificing 8mm "height" in moving from 19" to 20" but gaining 10mm width. Not saying the two compensate, but perhaps the ride difference isn't as big as people think.

Different story if you are going as far as 21" - boy those are thin.

Think the 19s and 20s but thought the 21s didn’t suit the car and obviously a personal hing thought it made it look a bit hot wheels ish 😀
