I just purchased some 18" rims from an '07 JK to put on my '09. I will be keeping the '09 spare on for now. What will this do to my TPMS? I don't think the '07's have the sensors.

 

Thanks for this info....even the dealer could not tell me this

 

You can:
1. Buy TMPS Sensors to install on your new rims
2. Deal with the light from them going off
3. Buy a programmer and turn of TMPS

 

Okay, got the placard.

So if on my door it says 35psi is recommended, the idiot light goes on at when it drops below 28 and will turn off once it is aired back up to at least 32.



As for the spare tire. I've noticed when the rubber on the ground is aired up properly, the spare tire (even when deflated to nothing) doesn't register and trigger my TPMS.

It did this as I jacked up one tire on a recent trip and had to change it on the trail. I drove with the deflated tire in the spare location on the tailgate for over a week with less than 10psi in it. Never triggered the TPMS idiot light.

 

How do you tirn tmps off via flashpaq?
