Notes:
Some i3 models may use different front and rear tire sizes or optional wheel diameters. If you are unsure, confirm by VIN with a BMW dealer and compare in the calculator.
M14 x 1.25 indicates fastener thread pitch. BMW typically uses lug bolts, but always verify visually on your car and match the seat type to the wheel design.
How To Use The Wheel Interchange Calculator
The calculator on wheelinterchange.com lets you test fitment safely before you buy. It compares Wheels from a donor vehicle against Installed on your vehicle, and you can try custom wheel and tire sizes.
Step 1: Set Installed on to 2020 BMW i3 and confirm the OEM values above match your trim. If they do not, enter your actual factory size from your tire sidewall and wheel stampings.
Step 2: In Wheels from, enter the donor vehicle specs or the specs of an aftermarket wheel you are considering.
Step 3: Use Custom wheel size to change rim diameter, width, and offset. Watch inner clearance to strut and outer poke to fender. The tool updates these distances as you adjust.
Step 4: Use Custom tire size to change section width and aspect ratio. When you change rim diameter, the tire diameter in the comparison updates so you can maintain ride height and speedometer accuracy.
Step 5: Aim to keep overall tire diameter change small, typically within about 2 to 3 percent, and verify no interference at full steering lock and full suspension compression.
Step 6: Print or save the comparison and confirm final choices with OEM documentation or your dealer before purchasing.
Fitment Checklist Before You Buy
Bolt pattern: Wheel must be 5x112.
Center bore: Wheel center bore must be 66.6 mm or larger. If larger, use hub-centric rings that reduce to 66.6 mm. Do not use a wheel with a smaller center bore.
Thread size: Fasteners must match M14 x 1.25. Verify seat type and required length, especially if using spacers or thicker wheel pads.
Offset and backspacing: Compare ET and backspacing in the calculator to ensure inner clearance to struts, springs, and brake lines, and to keep outer poke within the fenders.
Brake and suspension clearance: Check spoke-to-caliper clearance and barrel-to-caliper clearance. Some designs clear differently even with the same specs.
Tire load index and speed rating: Match or exceed OEM. EVs are heavy and need appropriate load capacity. XL or EV-marked tires may be required.
Overall diameter: Keep tire diameter change small to protect ABS, traction control, and range. Verify speedometer change in the calculator.
Staggered fitment: If your i3 uses different front and rear sizes, maintain correct axle-specific sizes and rotation direction if applicable.
Spacers: If used, they must be 66.6 hub-centric and paired with proper extended M14 x 1.25 hardware. Re-check thread engagement and local regulations.
TPMS: Determine whether your market uses wheel-mounted sensors. Transfer or program sensors as required.
Plus Sizing And Common Upgrades
Many owners explore alternative wheel widths or diameters. Actual availability and OEM approval vary by trim and market. If your vehicle differs from the values listed above, confirm with the VIN and compare options in the calculator.
Wider 19 inch options: Use the calculator to test modest width increases while watching inner clearance and outer poke. Keep offset balanced to avoid fender rub and steering heaviness.
Alternate diameters: If considering a different wheel diameter, adjust tire aspect ratio in the calculator so overall tire diameter stays close to stock. Verify brake clearance with the actual wheel template if available.
Range and ride considerations: Heavier wheels and wider tires can reduce EV range and increase road noise. Low rolling resistance options help maintain efficiency.
Hub-centric fit: For any aftermarket wheel with a larger center bore, use quality hub-centric rings sized to 66.6 mm inner diameter to prevent vibration.
Because factory configurations may vary, do not assume interchange without checking your exact trim. When in doubt, contact a BMW parts department and compare part numbers for your VIN.
Installation Tips
Preparation: Park on level ground, engage Park, and chock wheels. Use approved jack points and stands.
Surface prep: Clean hub faces and wheel mounting pads. Remove corrosion so the wheel sits flush. A light film of anti-seize on the hub centering lip only is acceptable. Do not lubricate threads unless specified by BMW.
Hardware: Match M14 x 1.25 threads and correct seat type. Hand start each fastener to avoid cross-threading. If spacers are used, install hub-centric spacers and use longer hardware as required.
Tightening: Snug in a star pattern, lower the vehicle, then torque to the OEM specification from your owner manual. Re-torque after 50 to 100 miles.
TPMS: Move or program sensors as needed. Replace valve stems and seals when transferring sensors to prevent leaks.
Final checks: Turn steering lock to lock and drive over bumps at low speed to confirm no rubbing. Monitor for vibration. If present, recheck hub-centric fit and wheel balance.
The wheel must center to 66.6 mm on the hub. If the wheel has a larger bore, use hub-centric rings with 66.6 mm inner diameter and the wheel’s outer diameter.
What fastener thread does the i3 use
M14 x 1.25. Verify whether your wheels require a specific seat type and confirm bolt length, especially when using spacers.
Can I use a 5x114.3 wheel with wobble bolts or adapters
Not recommended for safety. Use only 5x112 wheels that center properly at 66.6 mm. If adapters are considered, they must be hub-centric 66.6 both sides, high quality, and sized correctly, but direct-fit 5x112 is preferred.
What offset range will fit
Offset tolerance depends on wheel width, brake clearance, and your exact trim. Use the calculator to compare inner clearance and outer poke relative to your OEM setup, then confirm on the vehicle.
Do I need new TPMS sensors
Some markets use wheel-mounted sensors. Reuse or purchase compatible units as required and perform relearn or programming. Check your owner manual or dealer by VIN.
What is the correct torque for the wheel fasteners
Always torque to the OEM specification in your owner manual or service information. Do not guess. Re-torque after initial driving.
How far can I deviate from the stock tire diameter
Keep changes small, typically within about 2 to 3 percent. Use the calculator to see speedometer and clearance impacts before buying.
Will wider tires reduce my EV range
Often yes. Wider and heavier wheel-tire packages can increase rolling resistance and aerodynamic drag. Choose efficient tires and lightweight wheels to minimize impact.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
