hey guys, I just purchased a 2005 ls430 which was fitted with 18" rims from the factory but the previous owner had changed them to the 17's...can anyone with the 225/55/17's give me the correct psi I should be putting in the tires from the sticker on the door jamb...mine has the sticker for the 18's...thanks

 

Here you go, I looked it up in the online Lexus manual for you...

countries where such speeds are permitted by law, add 20 kPa

never exceed the maximum cold tire inflation pressure molded
on the tire sidewall.
