The tire pressure light came on this morning. I was near the dealership so I pulled into the service department and asked them to check psi. Each tire was 5 to 8 lbs under inflated!
Guess we should not rely on the psi indicator light? A visual inspection does not work either.
I have no idea how long the tires have been under inflated, but I have had terrible MPG and now the car rides a lot better. I'll be going to the auto parts store to buy a good tire gauge. The Michelin Pilot Sports are too expensive to ignore good maintenance.
By the way, the service advisor at the dealership didn't know much about the Crossfire...he didn't know how to get the car into reverse. Scary! On second hand maybe that's a good theft deterent.
