Stock sizes for this year lumina depends on the size of wheel that you have. Here's what the factory installed. 15" Wheels: P205/70R15 16" Wheels: P225/60R16
The "Sigma Shadows" usually run around $89.00 a piece, making two $179 + tax and tire removal, diposal, etc....
If the OEM size for the car is 205/55-16 then the 225/60-16 tires will NOT be a good choice as a replacement 60 series tires. They will be 7% larger in overall diameter and your handling, ride, fuel mileage, performance, and speedometer will be adversly effected. It is never recommended to go over or under 3%. If you wish to use a 60 series tire then you would need to install a set of 195/60-16 which wil be 1.35% larger in overall diameter and are acceptible.
