2015 BMW M5 Wheel Interchange

2015 BMW M5 Wheel Fitment and Interchange Guide | wheelinterchange.com

Known OEM Fitment For 2015 BMW M5

The values below are the known OEM data points provided for this vehicle. BMW often offers multiple wheel and tire packages and front and rear may differ. If a value you need is missing or appears to conflict, use the on-page calculator to compare options and confirm with the owner’s manual, the driver-door placard, and BMW parts information by VIN.

Note: The presence of a 20 in wheel diameter alongside a 19 in tire rim diameter indicates there were multiple OEM configurations or axle-specific sizes for this model year. Confirm which package your car has via the door-jamb tire sticker, your owner’s manual, or your VIN at an OEM parts source. If your setup differs, input your actual sizes into the calculator below to compare.

How To Use The Wheel Interchange Calculator

• Start with your car: In Installed on, select 2015 BMW M5. Enter your actual wheel and tire sizes from the door sticker or your current setup.
• Pick a donor: In Wheels from, choose a potential donor vehicle or manually enter the wheel specs you are considering.
• Adjust custom wheel size: Use Custom wheel size to set rim diameter, width, and offset for the wheels you want to test. The calculator shows inner clearance to suspension and outer poke toward the fender.
• Adjust custom tire size: Use Custom tire size to try different section widths and aspect ratios. When you change rim diameter, the calculator updates tire diameter in the comparison so you can keep overall rolling diameter reasonable.
• Review key results: Watch inner clearance, outer poke, overall tire diameter, and speedometer change. Aim to keep overall tire diameter close to your OEM package and ensure no loss of brake or suspension clearance.
• Finalize: If results are close, test-fit a single wheel on the car before buying a full set.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 5x120.
• Center bore: Hub-centric to 72.6 mm. If an aftermarket wheel has a larger bore, use quality hub-centric rings. If smaller, it will not fit.
• Thread size and hardware: M14 x 1.25. Match bolt length and seat type to the wheel. Do not assume seat type - confirm with the wheel manufacturer.
• Offset and backspacing: Compare ET 32 mm and backspacing 5.76 in with your target wheel using the calculator to avoid inner strut or outer fender contact.
• Brake caliper clearance: Visually verify spoke and barrel clearance over your calipers. Paper or clay check is recommended during test fit.
• Overall tire diameter: Keep total tire diameter close to your OEM package to protect ABS, DSC, and speedometer accuracy.
• Load rating: Wheels and tires must meet or exceed vehicle load requirements. Check stamped ratings.
• TPMS: Plan to reuse compatible sensors or install new ones that match your vehicle. Verify compatibility by VIN.
• Spacers, if needed: Only hub-centric spacers with appropriate extended M14 x 1.25 hardware. Recalculate offset effect in the calculator.
• Suspension and alignment: Lowered cars reduce inner and outer clearances. Factor any drop and camber settings into your comparison.

Plus Sizing And Common Upgrades

Plus sizing trades sidewall height for larger wheel diameter while keeping overall tire diameter similar. Use the calculator to keep overall diameter close to your OEM package and to preserve clearance.

• Plus-one or plus-two: Increase wheel diameter in 1 in steps, reduce tire aspect ratio appropriately, and compare overall diameter in the tool.
• Width changes: Increasing wheel width changes inner and outer positions. Split the added width half inboard and half outboard, then fine-tune with offset in the calculator.
• Staggered vs square: If your vehicle is equipped with different front and rear sizes, maintain that pattern unless you are intentionally moving to a square setup. Verify with the door sticker or OEM sources.
• Clearance first: Any upgrade must clear suspension, fenders, and brakes at full lock and over bumps. Always test-fit.

Installation Tips

• Prepare the hub: Clean the hub face and center pilot. Remove rust with a nylon or brass brush and wipe clean so the wheel sits flush.
• Hub-centric fit: Ensure the wheel centers on the 72.6 mm hub. Use rings only if the wheel bore is larger.
• Hardware check: Confirm M14 x 1.25 hardware, correct seat type, and proper shank length for the wheel and any spacers.
• Mounting: Hand start all fasteners. Snug in a star pattern. Final torque to the value in your owner’s manual after the car is on the ground.
• Spin test: After mounting, rotate the wheel by hand to check caliper, knuckle, and liner clearances.
• Road recheck: Re-torque after 50 to 100 miles. Verify no rubbing at full steering lock and over bumps.
• TPMS: Install compatible sensors and follow the relearn procedure specified for your vehicle.

Tools And Helpful Supplies

• 1/2 in drive torque wrench
• Wheel hanger guide pin M14 x 1.25
• 72.6 mm hub-centric rings for wheels with larger bores
• Digital tire pressure gauge

FAQs

• What is the bolt pattern for the 2015 BMW M5?

  5x120, as listed above.

• What center bore do I need?

  72.6 mm. If an aftermarket wheel has a larger bore, use quality hub-centric rings. If smaller, it will not fit.

• What thread size does the 2015 M5 use?

  M14 x 1.25. Match bolt length and seat type to your specific wheel and any spacers.

• The data shows a 20 in wheel and a 19 in tire. Which is correct?

  This indicates multiple OEM configurations for this model year or axle-specific sizes. Verify your car’s original sizes on the driver-door placard or owner’s manual, and use the calculator to compare your actual setup.

• Can I use wheels from another BMW with 5x120?

  Possibly, but you must also match center bore, offset, brake clearance, and load rating. Use the calculator to compare inner and outer clearances and confirm hub fitment.

• Will I need hub-centric rings?

  Only if the wheel’s center bore is larger than 72.6 mm. Rings adapt the bore to the hub for a vibration-free fit.

• What offset range fits this car?

  Offset requirements vary by wheel width, brake package, and suspension height. Compare your target wheel in the calculator against the known OEM ET 32 mm and physically test-fit.

• Are spacers safe to use?

  When used correctly with hub-centric spacers and appropriate extended M14 x 1.25 hardware, they can be safe. Always recalculate effective offset in the calculator and verify full clearance.

• What tire size should I run with a different wheel diameter?

  It depends on your package. Keep overall diameter close to your OEM setup. Use the calculator’s Custom tire size to find a combination that maintains diameter and clearance, then verify against the door sticker and OEM sources.
