I contacted 2 dealers today and both said that they can’t change the tire size even though I am trying to go from one stock size to another, so I was wondering if anyone had the same experience. I can buy an aftermarket module to perform the calibration/adjustment, but I thought I had read that the dealer can change it to another stock size so I wanted to prevent adding hardware if possible.
Sorry to revive an old thread but I didn't find anything more recent and on topic.
I recently swapped my stock 17" LT wheels for a takeoff set of 20" LTZ wheels. I purchased them from a place that deals in takeoff stock wheels for a variety of makes. I had the TPMS programmed at the time, and I assumed I could have a dealer change/correct the tire size to another stock size, 2 dealers I called said they can't do this on the current generation trucks.
Since I installed the 20" set I have been using a gps speed app on my phone part of the time I am driving and some of the time the speed is correct and some of the time it is off nearly 10% which is what I expected, as in one day it might match the app dead on and the next day I am going 10% faster than it reads. What is everyone doing to correct this or at least have it be consistent?
I picked up my new 2500 crew cab diesel on Saturday, traded in my 2016 silverado 1500 crew cab. This is the first diesel I've personally owned, but I have years of positive experiences with other duramax equipped 2500s, a 2013, a 2017, and another 2020. I'm looking forward to having my own.
