Expert Buying Guide for 2021 Rivian R1S
For your 2021 Rivian R1S, the bolt pattern is 5x139.7 with a center bore of 64.1mm. When selecting aftermarket wheels, ensure they have a bore of at least 64.1mm; use hub-centric rings to avoid vibration. The offset range is 30-48mm; staying within this range prevents rubbing and maintains suspension geometry. Always use M14x1.5 lug nuts with the correct seat type (conical or ball seat) to ensure proper clamping force. Incorrect lug nuts can lead to wheel loosening. Verify that aftermarket wheels are load-rated for the R1S's weight. Safety first: improper fitment compromises handling and safety.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to ensure proper seating.
- ✅ Avoid using wheels with a smaller center bore than 64.1mm; they will not fit without machining.
- ✅ Check that aftermarket wheels clear the brake calipers, as the R1S has large brakes.
- ⚠️ This fitment uses a wide offset range. Check brake clearance and fender clearance before buying wheels.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).

What other years of Rivian R1S have the same bolt pattern as the 2021?
The Rivian R1S uses the 5x139.7 pattern from 2021 through 2024. Wheels from any of these model years are dimensionally compatible with the 2021, provided the offset and center bore also match.
Can I put aftermarket wheels on my 2021 Rivian R1S?
Absolutely. Just ensure the aftermarket wheels have a 5x139.7 bolt pattern, an offset near 30-48mmmm, and a center bore of at least 64.1mm (using hub rings if larger).
What is the factory wheel offset for a 2021 Rivian R1S?
The OEM offset for the 2021 R1S is typically around 30-48mmmm. Depending on wheel width, a deviation of ±5mm is usually acceptable, but verify suspension clearance.
Why is matching the 64.1mm center bore important for the 2021 R1S?
The 64.1mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
Can I use spacers on my 2021 Rivian R1S?
Yes, but ensure the wheel spacers match the 5x139.7 bolt pattern and 64.1mm center bore. Also verify that you have enough thread engagement for your M14x1.5 hardware.
