Detailed tire and wheel breakdown for the 2011 BMW 3 Series
Tire geometry â 225/40R18
The 225/40R18 fitted to the 2011 BMW 3 Series has a section width of 225mm and an aspect ratio of 40%, mounted on a 18-inch rim. That gives a sidewall height of 90.0mm (3.54") and an overall outside diameter of 637.2mm (25.09"). At highway speed this tire completes roughly 500 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 2011 BMW 3 Series while keeping the speedometer accurate, target a 235/33R19 (plus-one). For a softer ride or winter setup, a 215/48R17 (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 2011 BMW 3 Series uses a 5x120 bolt pattern with a 72.6mm hub bore. Safe rim width range for the OEM tire is 7.5J â 8.5J, and offsets in the ET29 â ET39 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 2011 BMW 3 Series ships staggered: 225/40R18 up front and 255/35R18 on the rear. That is a 255mm vs 225mm 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 2011 BMW 3 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%.
