Good afternoon and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.

I see you said you took it to a Dodge dealership and they said they couldn't fix it? Is that correct? Did the technician even try to change the tire size in the ABS and TIPM modules? Without a scantool or programmer you will not be able to do this, we(Dealership) install lifts and bigger tires weekly and we have no issues reprogramming the tire sizes...

Let me know
