I got the 22s through the referral program. My first set of 20's were worn out and ready to be replaced when I got the call to schedule the appointment so it was good timing. I got 23k miles out of the 20s.
Range hit does suck but I haven't taken a road trip in a while so I don't really notice it. The range is plenty for my daily commute.
Road noise seems the same to me between 20 and 22. Maybe I'm just going deaf from the road noise in general. I still think the road noise is too high in the X.
