Expert Buying Guide for 2021 Rivian R1T
For your 2021 Rivian R1T, the 5x139.7 bolt pattern is shared with 2021–2024 models. The 64.1mm center bore is critical; aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load transfer. Offset must stay within 30–48mm to avoid rubbing or suspension interference. Use only M14x1.5 lug nuts with the correct seat type (conical or ball seat) to match the wheel. Never mix seat types—this can cause wheel loosening. Always torque to manufacturer specs and re-torque after 50–100 miles.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50–100 miles of driving to account for settling.
- ✅ Verify wheel bore diameter; if larger than 64.1mm, install hub-centric rings to prevent vibrations.
- ✅ Check offset carefully: too low (under 30mm) may rub suspension; too high (over 48mm) may contact brake calipers.
- ⚠️ 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).
