Right; Rubicons have never ever come with 18" wheels.
I'd go to a place like Discount Tire and have them help; they've always treated me very fairly.
You really should've kept your old sensors.... ....and never gotten the 18's. And if they really told you that the 18's came from a Rubi, they lied to you.
Unless the dealership did something funny with the original Rubi owner, like swap Sahara wheels onto it.
My TPMS will often trigger an alarm for several hours after a tire rotation; I have no idea why but your rig might be doing the same thing.
