The 2024 BMW iX uses a 5x112 bolt pattern with a 66.6mm hub bore. Safe rim width range for the OEM tire is 8.0J â 9.0J, and offsets in the ET31 â ET41 window will clear suspension and fender without rubbing on most setups.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 2024 BMW iX is printed on the driver-side door jamb sticker â always defer to that value, not to the maximum pressure printed on the tire sidewall. Check pressure monthly and before long trips; under-inflation by 20% can reduce tread life by 25%.
