Craig,
Ihave a 1998 LS 400 I just bought the Bridgestone Turenza 225-60-16 V rated for my car they are some of the best I have ever had! The car had toyo's on it when I got it, they also where very very soft poor in high speed long sweeping curves. The bridgestones are much better in all ways, no road noise and still a excellent ride! I payed $127.00 per tire at my local Firestone dealer pluse mounting.I run them at 35 PSI with no trouble at all in the wet, much better in the wet than the Toyos!
Good luck!
Jeff
