1999 Saab 9-5 — Frequently Asked Questions
What is the bolt pattern for a 1999 Saab 9-5?
The 1999 Saab 9-5 uses a 5x110 bolt pattern (also called lug pattern or PCD). The center bore is 65.1mm and the offset is 49mm.
What other years of Saab 9-5 have the same bolt pattern as the 1999?
The Saab 9-5 uses the 5x110 pattern from 1999 through 2011. Wheels from any of these model years are dimensionally compatible with the 1999, provided the offset and center bore also match.
What does 49mm offset mean for the 1999 9-5?
An offset of 49mm means the wheel's mounting surface is 49mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Saab.
Why is matching the 65.1mm center bore important for the 1999 9-5?
The 65.1mm 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 Saab 9-5?
The factory center bore (hub bore) for the 1999 Saab 9-5 is 65.1mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
Can I use spacers on my 1999 Saab 9-5?
Yes, but ensure the wheel spacers match the 5x110 bolt pattern and 65.1mm center bore. Also verify that you have enough thread engagement for your B 12x1.50 hardware.
Fitment Checklist Before You Buy Wheels
- Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
