I have a 2020 S60 T6 with factory Polestar tune. I have been having issues with the factory PZERO tires with foam cushioning in them giving me the typical vibration after 70 mph despite trying to balance. I was thinking of upgrading to a High Performance All Season or Summer tire. Just curious if any of you have noticed a handling improvement by doing so or is it minimal? I love the way the car drives, just wish the handling was a tad bid better. Thanks.
