Anyone running an L405 on 20" wheels - Smoother than 22's?

I have a 2016 Range Rover Autobiography 4.4 SDV8 which is currently running on 22" Turbine alloy wheels - While I love the way it looks with these bigger wheels, it's nowhere near as smooth as my old 2007 L322 4.4 petrol which runs on 19" wheels.

I'm thinking about changing the 22' wheels down to 20"s:

Has anyone done the same? Is it a lot smoother for the downgrade? And is it worth the change?

Please advise?

Many thanks

Thanks for that London GT3 - Is it only noticeably quieter / softer when you hit a pothole....... Or is it quieter / smoother in general - For example a less firmer ride / less tyre noise?

Many thanks

Thanks The Wookie - I know Bentley are putting these foam filled tyres on the new 2018 Mulsanne, and feedback has been good.

Thank you also to London GT3, It's good to know that the difference is noticeable. Short term I'll either go smaller rims or foam filled - Long term, I think I'm going to have to look at a 5.0 SC Petrol with smaller rims, I think it's the only way that I'm going to get close to our 2007 4.4 Vogue Petrol's quietness.

I did have a 5.0 SC Petrol on order but Land Rover kept moving the delivery date, it would have taken 9 months from date of order if I hadn't cancelled!

Thanks again to both of you for your comments
