BMW 320i Bolt Pattern, Wheel & Tire Sizes
TL;DR
5x120 on E90 and F30 generation 320i models, but 5x112 on the newer G20 (2019+); center bore and stud thread also changed, so confirm your generation first.
Bolt pattern changes across 320i generations
The BMW 320i has been built on three main platforms sold with that badge, and the wheel bolt pattern is not the same across all of them. On the E90/E91/E92/E93 (2005-2013, including the LCI facelift) and on the F30/F31/F34 (2011-2019), the bolt pattern is 5x120. On the current G20/G21 generation (2019-present), BMW moved to a 5x112 pattern, the same layout used on many other modern BMW and Mercedes-Benz models. Do not assume one figure applies to a car you have not identified by generation.
Center bore and stud thread
Center bore also differs: sources consistently put the E90 and F30 generations at roughly 72.5-72.6 mm, while the G20 uses a notably smaller bore of about 66.5-66.6 mm (sources vary slightly on the exact decimal). Stud thread size moved from M12x1.5 on the E90 (chassis code era) to M14x1.25 on both the F30 and G20 generations. We could not verify a manufacturer lug torque figure for this model from a credible source, so no torque value is given here - use the figure printed in your owner's manual or a torque wrench setting from a trusted repair source.
Wheel and tire sizes
Factory wheel and tire sizes vary widely by market, trim, and optional sport packages, so treat the table below as a general reference rather than a guarantee for your specific car. Wheels ranged from 16 to 20 inches across the F30 generation alone, and tire widths and profiles were adjusted accordingly by BMW for each wheel size offered.
| Generation / years | Bolt pattern | Centre bore | Stud thread | Stock wheel sizes | Common tire sizes |
|---|---|---|---|---|---|
| E90/E91/E92/E93 (2005-2013) | 5x120 | ~72.6 mm | M12x1.5 | 16-17 inch, 7J-8J | 205/55R16 to 225/45R17 (varies by trim) |
| F30/F31/F34 (2011-2019) | 5x120 | ~72.5-72.6 mm | M14x1.25 | 16-20 inch, 7J-8J | 205/60R16 up to 225/35R20 depending on wheel size |
| G20/G21 (2019-present) | 5x112 | ~66.5-66.6 mm | M14x1.25 | 17-18 inch, 7.5J typical | 225/50R17 or 225/45R18 (platform-typical; confirm your trim) |
Where to confirm your exact car
Because these figures shift by generation, market, and trim, always confirm your own vehicle's exact specification before ordering wheels or tires. The most reliable places to check are the driver's door placard (or the sticker on the door jamb), the tire and loading information label, the markings stamped on your current wheels and tires, your owner's manual, and BMW's manufacturer towing/wheel-fitment guide for your VIN.

Frequently asked questions
Is the bolt pattern the same on every BMW 320i?
No. The E90 (2005-2013) and F30 (2011-2019) generations use 5x120, but the current G20 generation (2019-present) uses 5x112. Confirm which generation you have before buying wheels.
What center bore does my 320i need?
It depends on generation: roughly 72.5-72.6 mm for E90 and F30 cars, and about 66.5-66.6 mm for the G20 (2019+). Hub-centric rings can adapt some aftermarket wheels, but always verify against your own hub.
What lug nut or bolt torque should I use?
We could not confirm a single manufacturer torque figure specific to this model from a credible source, so no number is given here. Use the torque value printed in your owner's manual or supplied by a qualified BMW technician for your exact model year.
Can I use E90 wheels on a G20 320i?
Not directly. The E90 uses a 5x120 bolt pattern and roughly 72.6 mm center bore, while the G20 uses 5x112 and about 66.5 mm center bore. These are not interchangeable without an adapter, which is not generally recommended for load-bearing wheel fitment.
