I had a set of 22” rims on my 2016 RR Autobiography LWB and switched to 20” rims w/dedicated Blizzak snow tires on them. I noticed a 10 mph difference between the speedometer and my Waze GPS . I wonder if this is because of the smaller rims? Has anyone had a similar experience? Thanks

Welcome to the forum. This issue isn't the rim size it is the outside diameter or the tires. Check out the sizes here for a good visual reference. https://tiresize.com/comparison/

I think the I D tool allows you to customize tire size for speedometer calibration.
