BMW 525td Spare Tire Sizes
The BMW 525td has used a 5x120mm bolt pattern for all models from 1985 to 1987 along with a tire diameter of 24.7" 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 BMW 525td spare tire selections. In this case, a 125/70R18 temporary spare tire is the recommendation for all applications.
