The BMW 323is has used a 5x120mm bolt pattern for all models from 1998 to 1999 along with tire diameters ranging from 24.7" to 24.9" 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 BMW 323is years and options. In this case, a 125/70R18 temporary spare tire is the recommendation for all applications.
