What do you guys inflate your tires to? Mine are all at exactly 32 psi, but my low tire pressure warning light keeps coming on. I'm just going to get it up to 40 pounds. They have a max rating of 51psi, but I want to see what you guys have in there first.

 

I follow Lexus' recommendations, which are on a sticker on the driver's doorjam. 35psi front and 37 psi rear.

 

32 in front,33 in back for a bit softer ride and no tire pressure warning pops up.
I've found my TPS goes off when tire is about 28 lbs.

 

same here for normal everyday use

 

Strange, my warning light just came on and all four tires are at exactly 25. First time I checked the pressure.


Now that I think about it, they probably delivered it to me with the tires under inflated and just now got low enough to set off the sensor.

 

I find the same thing, 28 and the warning light comes on. I use 35 front 37 back, except on the winter tires I use 35 all the way around. No TPMS on the winters.

 

32psi is to low.

Doesnt it say they need to be filled up to 37psi.

Mine TPMS kept on turning on and off too. I just filled up all 4 tires to 40psi and the warning hasnt come on yet. I hate guessing which tire is low so I just put 40psi on all 4 tires and bought a pressure guage.
