Expert Buying Guide for 2017 BMW i8
When selecting aftermarket wheels for the 2017 BMW i8, the 66.7mm center bore is critical. Most aftermarket wheels have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load distribution. The offset is sensitive: the factory spec is 39mm, and deviations beyond ±5mm may cause rubbing or clearance issues with the hybrid drivetrain components. Always verify lug nut compatibility: the i8 uses a 14x1.25 thread pitch with a ball seat. Using incorrect lug nuts (e.g., cone seat) can lead to wheel loosening. For 2014–2019 i8 models, wheels are cross-compatible, but always test fitment before finalizing.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50 miles of driving to ensure proper seating.
- ✅ Avoid spacers; the i8's offset is already optimized for suspension geometry.
- ✅ Check brake caliper clearance, especially with aftermarket wheels, as the i8 has large brakes.
- ⚠️ Confirm bolt pattern carefully. 5x112 is often confused with other common 5-lug patterns.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).

2017 BMW i8 — Frequently Asked Questions
What is the bolt pattern for a 2017 BMW i8?
The 2017 BMW i8 uses a 5x112 bolt pattern (also called lug pattern or PCD). The center bore is 66.7mm and the offset is 39mm.
What other years of BMW i8 have the same bolt pattern as the 2017?
The BMW i8 uses the 5x112 pattern from 2014 through 2019. Wheels from any of these model years are dimensionally compatible with the 2017, provided the offset and center bore also match.
Can I put aftermarket wheels on my 2017 BMW i8?
Absolutely. Just ensure the aftermarket wheels have a 5x112 bolt pattern, an offset near 39mm, and a center bore of at least 66.7mm (using hub rings if larger).
What does 39mm offset mean for the 2017 i8?
An offset of 39mm means the wheel's mounting surface is 39mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your BMW.
What is the factory wheel offset for a 2017 BMW i8?
The OEM offset for the 2017 i8 is typically around 39mm. Depending on wheel width, a deviation of ±5mm is usually acceptable, but verify suspension clearance.
Can I use spacers on my 2017 BMW i8?
Yes, but ensure the wheel spacers match the 5x112 bolt pattern and 66.7mm center bore. Also verify that you have enough thread engagement for your B 14x1.25 hardware.
