TV Tire Pressure Monitor System

Got a question. I want to upgrade the tires on my 2014 GMC Sierra 1500 from P255/70/R17's to LT265/70/R17's for the additional stability when towing. I questioned the GMC dealer where I bought the truck regarding the TPMS and they are telling me it will cost $110 to reset the system to account for the higher tire pressure in the LT series. Really, $110? Seems way high to me. Can this be done myself? I towed my MiniLite 2104S 10,000 miles last year on a cross country trip and didn't have any tire problems. Do I really need to go to a LT series tire and go thru all this expense? I would like to upgrade, but the $110 kills me. I've followed this forum for a while and I'm sure I'll get some good tips.

When I went from "P" to "E" tires Discount Tire took care of reprograming the TPMS on the truck, no charge but I paid plenty for the LT 275 65R20 Cooper tires.

Thanks PhoneDude. My tire place said they wouldn't do it. There are plenty of videos on how to re-learn the system, but I'm understanding the GMC dealer as saying going to a higher pressure is different from re-learning. I'll do more research on that.

Changing the threshold is more than just relearning.

That's was what I thought sine the tech at GMC said they had to reprogram the computer. He did say that because I had the towing package it could be done. Thanks for the response Kenny.

It's easily done, but you do need a factory scan tool.

Looks like I'm going to have to pay the $110. I really think the LT tires will be better in the long run.

I would wait until you get a longer, heavier trailer.

Ibrjet, so your saying you think the P series of tires are ok for what I'm towing? Like I said, I put 10K miles on the rig last year and really don't have anything to complain about.

Maybe you need a better more competent tire place. I deal with a store from one of the top 2 tire companies and they have the equipment needed to quickly re-set TPMS.
