I don't know if it's the tire or if Lexus LS owners have never driven a luxury car before, but my 2001 LS430 isn't any more quiet than my e39. On coarse asphalt the car rumbles quite loudly; on cement freeways at speed there is an incessant, pronounced road noise in the 250Hz to 2,000Hz range that sounds like, "SCHHHH", with virtually everything driven over producing thumps and bangs. Driving over fresh asphalt at the same speed silences the interior and provides immediate relief. I do not believe the LS430 to quite match Cadillacs from the 1980s in terms of noise and harshness suppression. The LS430 is quieter than a family sedan, but not by much.
The Bridgestone Potenzas may be part of the cause, I don't know. I bought the car with the tire. But past experience with an LS400 test drive years ago tells me the car is more to blame and not the tire...
