Tire pressure question
I was looking through the manual and I either overlooked it or it's not there. I want to know how many psi below recommended before you get the warning to add air?
Just took care of replacing my 2 bad front sensors and recalibrated the system and now my 2 rears(drag radials) are giving me the message to add air.

When I put the Nitto 555RII on my 2018, I was told not to go below 26psi or it would set off the low pressure alarms.
So far so good. I am running 26 psi in my rears and have not seen any warnings. When it warms back up, I might try 24 to see what happens, but it is too cold out.

OK, Thanks.. I would have thought somebody here would know how low it could drop before it saying to add air.

For the street I find no difference in traction from 26-29.

This was the 1st time I had the car say add air in addition to the light being lit.

26 is the number. I've had 25 slide by from time to time, but usually not.

Funny enough, mine had dropped to 24 when I took it out today, and I kept waiting for the low air light, but it never came on. They must've been just barely below 25, because just normal driving for a couple miles brought the pressures up to 25 and they even hit 26 off and on. Pretty sure that's the first time I've seen 24 with no light.
