Buick Lacrosse Spare Tire Sizes

The Buick Lacrosse has used 5x115mm and 5x120mm bolt pattern variations from 2005 to 2020 along with tire diameters ranging from 26.6" to 27.7" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Buick Lacrosse years and options. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications.
