Alright so Ive had my wheels and tires on for 5k miles, no problems with TPMS. Always register 30-35psi. I wanted to bump them up a little, about 35-40 but hadn't got around to it. While in for service at the dealership I told them what I wanted, said they couldn't because it would throw on a light. After arguing with them they said they could if they recalibrated the sensors, so I told them to do what they had to do, they are the experts. Talking with another one of their service techs he looked like I was on another planet and told me that they would have to pay GM $160 in order to recalibrate.

So after they're done (2 hrs of screwing with it) I get in my truck, and right front is showing 67 psi (rest are at 33), no light on though. So I took it back in the garage and asked them what the hell they did to my truck, "It must be the aftermarket wheels", then "Yeah, I guess we will need to replace a sensor now, looks like its not registering".

Does this make any sense? Sounds like they broke my sensor. And as far as the max psi in the tire, I figured there was a lot more range and recalibration isn't even necessary, not like I'm asking to put 80psi in them.

It will be going back in this week for them to fix, just wanted my truck back, and luckily its covered under warranty but I've about had it with these complete idiots.

It doesn't show as "too high" until 45 psi. Sounds like there are baffoons working at that dealerships. You should see my surprised face.

You should have been able to add a little more air without issue and without being charged

You figured this out too late.

On my truck my light doesn't come on until I hit 50 psi for the high side and I think 30 psi for the low side. On 2 sets of aftermarket wheels I have them set at 40-45 psi with no issues.
