This is my first post. I just bought new tires for my '03 CTS (my original Goodyears had only 38000 on them), but I don't know what the correct tire pressure should be. The placard on the side of the door only lists the gross weight and it seems like the pressure information must have washed or worn off. Also the new tires I bought (Yokahama AVID TRZ) list on the sidewall a maximum pressure of 40 lbs. When I checked the tire pressure the following morning while the tires were cold, they had 45 lbs in them. The papers I got with the tires listed a pressure of 35 lbs. The next problem I noticed was that when I picked up my car after having the new tires mounted and a 4 wheel alignment was that my clock had an incorrect time on it, as if the battery was disconnected. So I called the shop and asked if there would be any reason why the battery would be disconnected since the clock was wrong and they said no way. I later checked under the hood (which I should have done first) and saw that the battery terminal plastic covers were removed and hanging from their lanyards. What is going on with that? Sorry 'bout being so long winded....
