BMW 540iT Spare Tire Sizes

The BMW 540iT has used a 5x120mm bolt pattern for all models from 2002 to 2003 along with tire diameters ranging from 25.3" to 25.7" 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 BMW 540iT years and options. In this case, a 155/70R17 temporary spare tire is the recommendation for all applications.
