2011 XC60 20 inch rims & tires

[speeedww]

I own the T6 AWD Model and I'm at the point of replacing my tires. I was wondering if anyone here have switched their OEM 18" to 20" rims and tires? I've read a few reviews on the "R" model and noticed comments on the harsh ride and attributed theses comments to the combination of the sport suspension and the 20" setup; but on the T6 with the 20" setup I am anticipating an improved handling without the harsh ride.
