BMW iX Spare Tire Sizes
The BMW iX has used a 5x112mm bolt pattern for all models from 2022 to 2023 along with tire diameters ranging from 30.7" to 31.1" 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 iX years and options. In this case, using a non-temporary Full-Size tire as your spare, is the recommendation for all applications.
