I found some tires from a Rubicon I'm going to put them on my sport. They have the TPMS in them, will they sync up with my jeeps CPU or is there a step I have to take?
Any tips are greatly appreciated.

 

I swapped my 2012 Sahara's 18's to the 2011 70th 18's anniversy polished rim's and after adjusting all 5 rims from low 30 psi to 40 psi Tire pressure light is still on!!!! I have found that I can easliy ignore and maintain a come my own tire pressure.

 

I just had a strange oddity right along these same lines... I put on some slightly bigger wheels/tires from an X on my Sport this past weekend. The low tire warning was going off, despite that all 5 tires were properly inflated. Stayed on even after driving around for a bit, turning off/on a few times, etc... Came to the conclusion that the TPMS sensors might have just been different and incompatible (different model year wranglers or something like that) and I was prepared to just live with the message. Then come Monday morning, turned on the Jeep, no low tire message... drove around, no low tire message... and hasn't come back since.

 

Most tire shops can recalibrate to your new TPMS sensors.
