This is kinda annoying, I got an IS250 AWD around Feburary when I drove off the lot like 10 mins later... I got the low tire pressure warning light on so the next day I took it back to lexus and they put nitrogen in and promise it won't happen again because nitrogen won't lose density regardless of temperature. So I drove my car tonight and enjoy the ocean view for an hour, turn my car on dang got that stupid warning light again... (its 52degree tonight so ya)

It's been 10 months since you put Nitrogen in your tires!!! You should be checking your tires once a month at the minimum. Nitrogen does not guarantee that there will be no pressure loss. You need to top up, that's all. Or you might have a puncture in one of your tires. Just have it checked out.

I had a similar issue with my wife's 4Runner. I was getting all upset because the light kept coming on.... and then it turned out that one of the wheels had a leaky valve. Moral of the story: check your tires before you get annoyed with the TPMS.

Dude, just check your tire pressure and fill them up. If you went since Feb. without filling them, I'd say thats pretty damn good, esp. in NY type of weather. Do the dealer a favor and just check first before wasting their time.

This is user error. Check your tire pressure every month or two and the "annoying" light won't come on. Your car would pimp slap you if it could.

U might have something inside the tire.. Go to tire store and ask to check in the tire for nail or something leak. It happed to my fiancee and the dealership dont help that much. They just look at the tire and said nothing wrong.. That is bull**** and it keep flat again.. I gave up and take the car to the Discount tire.. The installation dismount the tire and found 1 foot long railroad nail... WTF is that man? HOw idiot of the dealership let my fiancee ride the car with railroad nail.. That is really **** me off..

Exactly.

I use nitrogen and must add more at times though less times than regular air..I top off with a 11 gal tank filled with nitrogen.Nitrogen is said to last 6x longer than regular air but you still have to top off tires.
After 10 months you will have a big drop in pressure.

I dont get where you guys get "10 months", he stated "10 MINS" later.
My suggestion is for you to locate the problem. Fill your tires up again and check it the next day to see which tire's pressure drops the most. And when you find the problem, go to a tire shop to check the tire for any puncture.

Oops must've missed that .

Anyways, go buy yourself a $2 air guage and check it once in a while.

yea, make sure you check your pressure all the time on these wheels and tires. Too bad I didn't or else I know for sure I can get 10k more. So for I got 36k miles on my origional tires. my inside and outside are gone due to driving while my tire pressure is low.
