Buick Reatta Spare Tire Sizes

The Buick Reatta has used a 5x115mm bolt pattern for all models from 1988 to 1991 along with tire diameters ranging from 26.0" to 26.2" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicle applications. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Buick Reatta years and options. In this case, a 165/70R17 temporary spare tire is the recommendation for all applications.
