Proper tire inflation is critical to the safe operation of all vehicles. Tire pressure specifications can be found on an inflation sticker on the driver's door frame or in the owners manual. Fuel mileage, increased tire wear, ride quality, handling, and road noise are just a few of the problems that might arise from improperly inflated tires.
All models up to 2007 with cast aluminum wheels may experience a loss of air pressure that is due to porosity in the aluminum casting. Have your repair shop refer to GM SB-05-03-10-003B for instructions on how to repair this problem.
For all 2008–2009 Buick models with the tire pressure monitoring systems (TPMS), the warning light may stay on due to a software issue with the tire pressure monitor control unit. There is updated control module software available from the dealer to correct this concern. In some cases, the control module and/or other parts of the TPMS may also need replacement. You should always check your tire pressures when you see this warning light, including the spare tire.
Buick Century or Regal 1999–2000
Due to internal faults with the electronic brake and traction control module (EBTCM), the low tire pressure warning message or light may illuminate when the tire pressures are not low. If this is the case, the EBTCM will need to be replaced to correct this fault (SB-01-03-10-008A).
Buick Century 1999-1996 and Buick Lesabre 1990–1999

Buick Lucerne 2000–2007
Due to an internal fault with the tire pressure monitor control unit, the tire pressure monitor message might come on. It is recommend to replace the control unit, its antenna, and the door lock remotes to correct this concern (SB-07-08-52-001B).
Buick Roadmaster 1990–1996
If you experience looseness in the steering and abnormal wear of the front tires, it may be from the idler arm, pitman arm, or center link components of the front steering linkage. After replacing any of these components, the front end alignment should be checked and adjusted if necessary.
