Tpms fixed

[6.4 dude]

Went for service today and received pcm update. No more tpms alarms at 65 psi!! I didn't realize till I got a mile down the road or I would have asked about it. Drove around 2 hundred miles with no alarms.....

In the rear or front? Are you running 65 all around?

 

[SouthernBoy]

Is there a flash number/version on your service reciept ?

 

[6.4 dude]

65 psi on all tires. The flash was 0.20 amp flash?

Interesting, I have to swap my front tires to rear as the rears are wearing much quicker and the 80-84psi they run at isn't helping things. I had the PCM flashed a couple weeks ago for other reasons, I wonder if that update would allow me to drop to like 70-75psi rear without setting off the tire nazis.......

You can run 65 rear. 64 will set off tpms. 70psi is no problem at all.

Not on mine before the flash. My alarm went off at 74 psi on rears.

You can run 65 rear. 64 will set off tpms.

That's how mine works.

I ran mine with no issues at 68 front and back. At 60 now, rear sensors bark.

Well, about 3 weeks ago, after the Air Lift 5000 install, I decided to drop the pressure in the rear tires to 65 to see if it would set off the TPMS. It didn't and hasn't to this point. I also have the severe wear of the rear tires. Of course, when towing, will have to re inflate but that's ok. Also, after having a 140# grill guard installed "Moose catcher" did have to inflate 5# over on the front tires. You couldn't see it in the tires but the steering felt a little heavy. After a 5# increase, feels like normal. Not sure if when towing, will have to go back to the original pressure in the front. Will watch for wear and also handling feel.

Not on mine before the flash. My alarm went off at 74 psi on rears.

Where does the alarm go off now?

 

[6.4 dude]

I don't know. I keep my tires at 63-65 psi and haven't went any lower.

I'll have to bother my dealership about it..im sick of this light. I run 55/50 in my tires and the front tpms has not gone off at all

 

[6.4 dude]

Well hell, one tire went into alarm @ 69 psi hot. So much for that....
