Almost every time my 2014 Cruze or my 2010 Malibu go into a dealer or shop for work that involves the tires they come out with problems. The most common error is that they don't relearn the TPMS sensors so the DIC display for front left tire is really indicating back rear or something. This weekend, instead of going to the dealer, I tried a seemingly well liked, busy tire shop to have my winter tries removed and the Fuel Max tires put back on. When we picked the car up, all 4 tires were 6-8 PSI low, TPMS light on and I have to assume they didn't relearn the sensors. So I had them rework it.
I tried to make small talk with the front desk guy and asked if there were differing opinions on where to get tire pressure guidelines from. I know some people experiment with different pressures and have a number that is a few PSI one way or the other from factory but for at least the least 20 years, the door jamb sticker is the official default pressure to use. Strangely, this place said they usually just aim for 32 PSI (on cars at least). So irritating. I tried politely suggesting that things are changing (have changed) in the tire world and a lot of vehicles will have higher PSIs in the future with more Low Rolling Resistance tires etc.
Personally, I think TPMS is great and in particular, GM's individual tire pressure readings are really great. But I have to believe that a LOT of people in the industry either resent TPMS or just ignore it altogether. I've also run into cars with TPMS warnings on rental cars etc. I don't understand how somebody gets in a car, moves it around (out of a service bay, out of the rental car cleaning bay etc), sees a warning light and does nothing about it.
