Today I got new tires on the car. Much to my chagrin, as I was having the guy adjust the PSI, the gauges were reading the wrong tire. This seems to point to the fact that the sensors are TIRE SPECIFIC (since it didn't appear to re-learn the new tire locations...yet at least) which seems a little odd to me. I didn't have any warnings coming home where I hit 80+ mph so I don't think it's a BIG deal, but if I do have a blowout or PSI problems it will of course read the wrong tire.
So if this bothers you, make sure to mark your tires as you take em off to have the tires changed. For tire rotation I guess they have to take the tire OFF and switch it and re-inflate. Can anyone corrobrate this?
