drove my car for about a week or two, hit the display button to check the PSI. they were off. both passenger side tires were 38 and the driver front was 37 back drivers side was 40. was told it would adjust itself. checked again yesterday and it was the same. took the car to lexus to resolve the issue. was told 35 front 36 back. checked when i parked at my house they all said 37. should i have them put nitrogen in my tires? i heard it was much better and that it holds the PSI at the proper pressure.

 

pressure should only be measured when it's cold, meaning first thing in the morning before you start it. you drive home and check and that's a lot of heat already.

plus, nitrogen, imho that's just a gimmick and pretty useless for daily application. on all my cars it's just normal air and i have never had any problems

 

okay nitro a no go....thanx rominl. i will leave well enough alone. Club Lexus has helped me alot most of you guys are very helpful and informative, really appreciate your feedback.

 

if you want to be sure, try 2-3 saturday morning, check the pressure and see if each wheel stays about the same

 

Our dealership puts nitrogen in all of our new cars and they seem to be consistent
