Proper Manufacturers Tire Pressure For 18"s

[Jeff]

Hi all, I own a 1999 LS400 with factory 16's on it. I just purchased new Lexus LS430 18 inch tires and wheels off of a 2004 to replace the 16's . My question, what is the proper tire pressure for the 18's on the LS ? If somebody could check the specs on there LS430 with factory 18's and let me know, I would be grateful.

if you can't find the factory specification, start with 4-5 lbs below max for a start.
