Tire Pressure Sensor

I just installed a ProComp 2.5" lift. I'm still shopping for wheels and tires. Here's my question...I'll be going up to either 34's or 35's, I'm assuming that the suggested psi will be different. If it is, I'm guessing that that will throw up the tire pressure light because the computer is set for stock tires. Will I need to do something else to change the computer? Any help would be appreciated. Thx

Air pressure is air pressure, regardless of the volume.

That said, you will need to put the TPMS in the new wheels or leave them out and deal with the tire pressure light.

You can get a device to reprogram the computer to allow for different pressure threshholds to trigger the light or recalibrate your speedo for diff tire diameters.

Superchips Flashcal will adjust your tpms setting and correct your speedometer
(which will in turn correct your shift points, if yours is an auto)

I run 35s @ 29psi, and set my TPMS to 25... that way I'll know if I have a slow leak or
other loss of pressure before it gets serious.

Also, the Flashcal gives you the option of changing your running light/security beep & light flash + other settings as well.

Same here. Hated those POS things. I would get a light and check the pressure with a gauge. Everything would be fine. My 07 Titan was the first vehicle I had with TPMS and I always got false calls. Same issues that I had with my JK.

Found a set of 17" rims (jeeps 5 star rims...my sport came with the steel mini 16" pizza cutters). Rims and tires , which were basically brand new for 300.00. Guy I bought them off of said he didn't keep the TPMS in the set and I said perfect. So I get the "DING" and lit up icon on the dash, but I don't care. I always walk around my jeep before I get in and if anything looks odd, I just grab the air pressure gauge and check.

Also, just a reminder, if you plan on using fix-a-flat, it's a big no-no with these sensors.
