Expert Buying Guide for 1999 Acura RL
For your 1999 Acura RL, the bolt pattern is 5x120 with a 64.1mm center bore. Aftermarket wheels often have a larger bore, so hub-centric rings (64.1mm ID to wheel's bore) are essential to prevent vibrations and ensure proper load transfer. The factory offset is 50mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify offset with test fitting. Lug nuts are 14x1.5 thread pitch with a conical (60-degree) seat. Using incorrect seat type (e.g., ball seat) can lead to wheel loosening. Re-torque after 50-100 miles. Wheels from 1996-2012 Acura RL are direct fit.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 80 ft-lbs after 50-100 miles of driving.
- ✅ Avoid using wheels with a center bore larger than 64.1mm without hub-centric rings.
- ✅ Check offset carefully: 50mm is ideal; going lower (e.g., 45mm) may cause fender rubbing.
- ⚠️ Confirm bolt pattern carefully. 5x114.3 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).
1999 Acura RL — Frequently Asked Questions
What is the bolt pattern for a 1999 Acura RL?
The 1999 Acura RL uses a 5x114.3 bolt pattern (also called lug pattern or PCD). The center bore is 64.1mm and the offset is 50mm.
What other years of Acura RL have the same bolt pattern as the 1999?
The Acura RL uses the 5x114.3 pattern from 1996 through 2012. Wheels from any of these model years are dimensionally compatible with the 1999, provided the offset and center bore also match.
What is the PCD for a 1999 Acura RL?
PCD stands for Pitch Circle Diameter, which is the same as the bolt pattern. For the 1999 RL, the PCD is 5x114.3.
What does 50mm offset mean for the 1999 RL?
An offset of 50mm means the wheel's mounting surface is 50mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Acura.
Why is matching the 64.1mm center bore important for the 1999 RL?
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.
What is the center bore of a 1999 Acura RL?
The factory center bore (hub bore) for the 1999 Acura RL is 64.1mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
