Detailed tire and wheel breakdown for the 1996 BMW 5 Series
Tire geometry â 235/45R17
The 235/45R17 fitted to the 1996 BMW 5 Series has a section width of 235mm and an aspect ratio of 45%, mounted on a 17-inch rim. That gives a sidewall height of 105.8mm (4.16") and an overall outside diameter of 643.3mm (25.33"). At highway speed this tire completes roughly 495 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 1996 BMW 5 Series while keeping the speedometer accurate, target a 245/38R18 (plus-one). For a softer ride or winter setup, a 225/53R16 (minus-one) keeps the overall diameter within Âą3% of stock, which is the industry tolerance for ABS and stability control to stay calibrated.
Wheel fitment specs
The 1996 BMW 5 Series uses a 5x120 bolt pattern with a 74.1mm hub bore. Safe rim width range for the OEM tire is 7.5J â 8.5J, and offsets in the ET15 â ET25 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 1996 BMW 5 Series ships staggered: 235/45R17 up front and 255/40R17 on the rear. That is a 255mm vs 235mm width difference â do not rotate front-to-rear, and replace tires in axle pairs to keep ABS and traction control balanced.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 1996 BMW 5 Series 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%.
