2014 BMW i3 Wheel Interchange

2014 BMW i3 Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2014 BMW i3

The specifications below reflect one verified OEM configuration for the 2014 BMW i3. Other trims or option packages may differ. If your vehicle’s placard shows different sizes or ratings, follow the placard and BMW service information. Use the on-page calculator to compare any alternatives before you buy.

How to confirm your exact OEM spec: check the driver door jamb tire placard, your owner’s manual, or a BMW dealer using your VIN. If any values above differ on your car, rely on OEM sources first.

How To Use The Wheel Interchange Calculator

The calculator on this page lets you compare two setups to visualize clearance, poke, ride height effect, and speedometer change.

• In “Installed on (your vehicle)” select 2014 BMW i3 so the baseline uses your OEM data above.
• For “Wheels from (donor vehicle)” pick a potential donor car or enter a “Custom wheel size.” You can change rim diameter, width, and offset, plus tire section width and aspect ratio.
• When you change rim diameter, the tool updates tire diameter in the comparison so you can see the impact on fender gap and speed reading.
• Watch inner clearance to the strut and brake components, and outer poke relative to the fender. Positive inner clearance means more room inboard. More poke pushes the wheel outward.
• Use the tire size inputs to keep overall tire diameter close to stock. Many users target a small variance to protect ABS, stability control, and range.
• If you are testing spacers or different offsets, adjust ET or spacer thickness and recheck inner and outer clearances.
• Save or print the summary before purchasing wheels or tires.

Fitment Checklist Before You Buy

• Bolt pattern: 5x112 must match. Do not force-fit or use wobble bolts on safety-critical EV applications.
• Center bore: OEM hub is 66.7 mm. Aftermarket wheels with larger bores require 66.7 hub-centric rings. Wheels with smaller bores will not fit.
• Thread size and fasteners: M14 x 1.25. Confirm your wheel fastener type and seat profile with the wheel manufacturer. Do not mix ball-seat and cone-seat hardware.
• Offset and backspacing: OEM ET is 43 mm with 4.19 in backspacing. Changes in offset affect both inner clearance and fender poke. Use the calculator to quantify any change.
• Brake and suspension clearance: Test for spoke-to-caliper and barrel-to-strut clearance. The calculator helps, but always test fit.
• Tire outside diameter: Keep overall diameter close to stock to maintain correct speedometer and driver-assist functions. Use the calculator’s tire comparison to verify.
• Load index and tire construction: Select tires that meet or exceed the OEM load index. EVs benefit from XL or EV-designated tires for load and efficiency where specified by the tire maker.
• TPMS: The 2014 BMW i3 uses TPMS. Sensor type and frequency can vary. Reuse your sensors if compatible or purchase compatible replacements. Program or relearn per BMW procedures.
• Staggered vs square: If your car has staggered sizes, front-to-rear rotation is limited. A square setup simplifies rotations but confirm clearance on both axles.
• Spacers and adapters: If used, choose hub-centric parts and correct-length fasteners. Recheck thread engagement and fender coverage in your region.
• Torque specs: Wheel torque values can vary by wheel and fastener. Refer to your owner’s manual or BMW service information. Tighten fasteners in a star pattern and re-torque after short mileage.

Plus Sizing And Common Upgrades

Owners often explore plus sizing for appearance or handling. Compatibility depends on exact width, offset, and tire choice. Use the calculator and verify on the car before purchase.

• Plus 0 or Plus 1: Increasing rim width on 19 in wheels or moving to a larger rim diameter can work if the tire’s overall diameter and offset are selected carefully. Check inner and outer clearances at full steering lock and over bumps.
• Tire diameter target: Many aim to keep overall diameter within a small percentage of stock to preserve speedometer accuracy and driver-assist calibration. Validate with the calculator.
• Range and comfort: Larger and wider wheels typically increase weight and rolling resistance. Narrower, low-rolling-resistance tires usually help range and ride comfort.
• Winter setups: Narrower tires can improve snow performance. Ensure load index and speed rating meet OEM requirements.
• If your i3 came with different OEM sizes: Variations by trim or package may exist. Confirm what your car shipped with using the door placard or VIN lookup, then base any plus sizing off that exact spec.

Installation Tips

• Use proper jacking points and support the vehicle on stands before removing wheels.
• Clean the hub face and the 66.7 mm hub pilot with a wire brush. A very light, non-migrating anti-seize on the hub pilot can help prevent corrosion. Do not lubricate fastener threads unless BMW specifies it.
• Test fit each wheel. Spin by hand to verify no contact with calipers, knuckles, or struts.
• Tighten fasteners by hand first to avoid cross-threading. Torque in a star pattern to the OEM specification from BMW service information.
• If using hub rings, seat them fully on the wheel before mounting.
• After driving 50 to 100 miles, recheck torque and inspect for any rubbing at full lock and over bumps.
• TPMS: Follow the owner’s manual for sensor relearn or initialization after installation.

FAQs

• What is the 2014 BMW i3 bolt pattern?

  5x112.

• What offset should I use on the i3?

  The verified OEM offset is ET 43 mm. For other wheels, use the calculator to compare inner clearance and outer poke to OEM and test fit before driving.

• What is the OEM center bore?

  66.7 mm. If your aftermarket wheel has a larger bore, use hub-centric rings sized to 66.7 mm ID. A smaller bore will not fit.

• What tire size came with this setup?

  155/70R19 based on the provided OEM dimensions. Some vehicles may have different factory sizes. Confirm with your tire placard or VIN lookup.

• Can I use 20 inch wheels?

  Compatibility can vary by width, offset, and tire choice. Use the calculator to model a 20 in setup, keep overall tire diameter close to stock, and verify brake and fender clearance with a test fit. Confirm load index and TPMS compatibility.

• Do I need new TPMS sensors?

  You can often transfer existing sensors if they are compatible with the new wheels and valve seats. If buying new, ensure sensor compatibility for the 2014 i3 and follow BMW relearn or initialization procedures.

• What is the correct wheel torque?

  Torque values are not provided here and can vary. Follow the BMW owner’s manual or service information for the 2014 i3. Re-torque after short mileage.

• Can I rotate my tires?

  If all four tires are the same size and offset, a standard rotation is possible. If your i3 uses a staggered setup, front-to-rear rotation typically is not possible. Check your current sizes first.

• What does the 4.19 in backspacing mean?

  Backspacing is the distance from the wheel mounting pad to the inboard rim edge. The OEM backspacing here is 4.19 in, which together with width and offset determines inner clearance. Use the calculator to see how changes affect this value.

• Are spacers safe on the i3?

  If needed for clearance, only use quality hub-centric spacers with proper-length fasteners and sufficient thread engagement. Re-evaluate inner and outer clearance in the calculator and confirm local regulations.
