2019 BMW i3 Wheel Interchange

2019 BMW i3 Wheel Fitment Guide

Known OEM Fitment For 2019 BMW i3

The following specifications are confirmed for at least one 2019 BMW i3 configuration. Other trims or option packages may differ. If your car’s placard or build sheet does not match, use the on-page calculator and verify with OEM documentation or your VIN at a BMW dealer.

Where your vehicle differs from the table, rely on the tire placard on the driver door jamb and the calculator on this page to model any proposed wheel or tire changes before purchase.

How To Use The Wheel Interchange Calculator

• Start with your car: Select Installed on (your vehicle) as 2019 BMW i3.
• Pick a donor: In Wheels from (donor vehicle), choose the vehicle or wheel you are considering. If you only know wheel specs, use the Custom wheel size fields.
• Adjust wheel specs: Enter the rim diameter, rim width, and offset. The calculator will show inner clearance to suspension and outer poke relative to your OEM baseline.
• Adjust tire specs: Enter section width and aspect ratio. When you change rim diameter, the tire diameter in the comparison updates so you can see speedometer and fender gap effects.
• Interpret results: Aim to maintain overall tire diameter within about plus or minus 3 percent of stock, preserve adequate inner clearance to struts and control arms, and avoid excessive outer poke that could contact fenders on compression or steering.
• Finalize: Confirm that center bore, bolt pattern, seat type, and load rating are compatible. When in doubt, check the owner’s manual and OEM parts catalogs.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 5x112. Do not use 5x114.3 without adapters and engineering review.
• Center bore: BMW i3 hub is 66.6 mm. If the wheel hub bore is larger, use hub-centric rings sized to 66.6 mm at the hub side. If smaller, the wheel will not seat.
• Offset and width: Compare your candidate setup in the calculator. Ensure inner clearance to strut, spring perch, and bodywork, and confirm outer poke stays inside fender liners through full suspension travel and steering lock.
• Backspacing: The OEM reference is 4.19 in with a 19x5.0 ET43 wheel. Use this to sanity-check changes.
• Tire clearance: Model steering clearance and suspension compression. Watch for contact with front liners and rear arch trim.
• Load rating: Wheels and tires must meet or exceed the i3’s axle loads. EV mass and torque put more demand on components.
• Fastener compatibility: Thread size is M14 x 1.25. Verify the correct bolt length and seat type for the wheels you choose. If you add spacers, use appropriately longer bolts with full thread engagement.
• TPMS: If equipped with direct sensors, plan to transfer or program compatible sensors. Check your owner’s manual or local regulations.
• Brake and spoke clearance: Confirm that calipers clear barrel and spokes. Visualize with the calculator and physically test-fit when possible.

Plus Sizing And Common Upgrades

Some 2019 i3 vehicles may use different wheel and tire sizes depending on trim or package. If your car’s placard differs from the table above, use those OEM values as your baseline in the calculator.

• Diameter strategy: Keep overall tire diameter within roughly plus or minus 3 percent of your OEM reference to limit speedometer error and drivetrain strain. Use the calculator to see the exact percentage change.
• Width changes: Increasing wheel width can improve stability, but can also reduce inner clearance and add outer poke. Model both effects and inspect your vehicle for room at full lock.
• Offset tuning: Lower ET pushes the wheel outward, higher ET moves it inward. Small changes can have big effects on clearance. Compare directly against the OEM ET43 baseline.
• Tire selection: Maintain equal or higher load index and suitable EV-ready tires. Re-evaluate wet and winter performance when going wider.

If you are unsure whether your i3 is equipped with an alternate OEM wheel package, confirm by VIN with a BMW dealer or check the driver door placard, then feed those exact specs into the calculator.

Installation Tips

• Prepare the car: Park on level ground, set the parking brake, and chock wheels.
• Lifting: Use proper jack points and stands. Many BMWs accept jack pad adapters to protect the body and undertray.
• Hub prep: Clean the 66.6 mm hub face and center spigot. Remove corrosion so the wheel seats flush.
• Hub-centric rings: If your wheel bore is larger than 66.6 mm, install rings before mounting.
• Bolt seating: Hand-start M14 x 1.25 bolts to avoid cross-threading. Verify the seat type matches the wheel’s design.
• Torque: Tighten in a star pattern with a calibrated torque wrench to the value specified in your BMW owner’s manual. Re-check torque after 50 to 100 miles.
• TPMS: Install compatible sensors or transfer your originals. Perform relearn or programming per the service manual.
• Road test: Listen for rubbing over bumps and at full steering lock. Inspect for witness marks inside and outside the wheel well.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• M14 x 1.25 wheel bolts or extended bolts for spacers
• 66.6 mm hub-centric rings
• TPMS service kit or sensors

FAQs

• What is the bolt pattern for the 2019 BMW i3?

  The confirmed bolt pattern is 5x112.

• Do I need hub-centric rings for aftermarket wheels?

  If the wheel’s center bore is larger than 66.6 mm, use rings that reduce it to 66.6 mm so the wheel centers on the hub. If the wheel bore is exactly 66.6 mm, rings are not needed.

• Will wheels from another 5x112 vehicle fit my i3?

  They may physically bolt on, but you must also match center bore, offset, brake clearance, load rating, and fastener seat type. Use the calculator to compare dimensions, then verify with OEM specs.

• What tire and wheel sizes came on all 2019 i3 models?

  Sizes can vary by trim or package. The table above lists a known configuration, but your vehicle may differ. Check your driver door placard and confirm by VIN if needed.

• What is the correct torque for the wheel bolts?

  Follow the torque specification in your BMW owner’s manual or service information. Do not guess. Re-torque after 50 to 100 miles.

• Do I need new TPMS sensors with new wheels?

  If your i3 uses direct TPMS, you can transfer existing sensors or install compatible new ones. Perform relearn or programming as required. Check local regulations and the owner’s manual.

• Can I run a staggered setup?

  Some configurations may differ from square fitment. Verify what your specific i3 uses on the door placard, then model any change in the calculator to ensure proper clearances.

• How much offset change is safe?

  There is no single number that fits all. Use the calculator to see inner clearance and outer poke changes relative to the OEM ET43 wheel, then measure your car for real-world clearance before buying.

Always verify final selections against OEM documentation. Use the calculator on wheelinterchange.com to compare any candidate wheel or tire package to your 2019 BMW i3 before purchase.
