My experience with them is on a Lexus LS430 - the selling dealer installed a set of Goodyear Eagle RS-As. It needed tires after having the traction control kick in on a dry road out of the blue and again on a slightly wet freeway. The Eagles were hard as steel. The parents said get tires ASAP, but only from Costco - I was considering the Yokohama Avid Ascend GT for it. I was looking at the the options Costco had - it was between the Potenza RE980AS or the PSAS4. QuietTracks or CC2/Primacy MXM4/Primacy A/S would have been more appropriate for an luxobarge.
It transformed the car as soon as I drove away from Costco. It made a big, lazy Lexus sedan feel almost kitten-like. I imagine either the DWS06 or PSAS4 will make a lowly Prius a little more engaging to drive. A lot of Prii I see are on the cheapest Chinesium - LingLong/Leao, WestLake, Advanta or Sailun I’ve seen around here - lots of them are Ubers or Doordashes here.
