Expert Buying Guide for 2009 Scion tC
For the 2009 Scion tC, the bolt pattern is 5x100 with a center bore of 54.1mm. Aftermarket wheels often have a larger bore, so hub-centric rings are essential to prevent vibration and ensure proper load distribution. The factory offset is 45mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify offset with test fitting. Use only 12x1.5 lug nuts with the correct seat type (factory is conical/60-degree). Mixing seat types (e.g., ball seat) can lead to wheel loosening. Re-torque lug nuts after 50-100 miles of driving.

Quick Tips & Safety Warnings
- ✅ Always use hub-centric rings (54.1mm inner diameter) when installing aftermarket wheels to avoid vibration and hub damage.
- ✅ Stick within ±5mm of the factory 45mm offset to prevent rubbing on suspension or fenders; test fit before finalizing.
- ✅ Re-torque lug nuts to 80 ft-lbs after 50-100 miles; use a torque wrench and check periodically.
- ⚠️ 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).
- ⚠️ This model has multiple bolt-pattern records across years. Match wheels to exact year/trim before purchase.

2009 Scion tC — Frequently Asked Questions
What is the bolt pattern for a 2009 Scion tC?
The 2009 Scion tC uses a 5x100 bolt pattern (also called lug pattern or PCD). The center bore is 54.1mm and the offset is 45mm.
What other years of Scion tC have the same bolt pattern as the 2009?
The Scion tC uses the 5x100 pattern from 2005 through 2010. Wheels from any of these model years are dimensionally compatible with the 2009, provided the offset and center bore also match.
How tight should I torque the lug nuts on a 2009 Scion tC?
Refer to your owner's manual for exact specs, but always tighten the 12x1.5 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
How do I measure the bolt pattern on my 2009 Scion?
The 2009 tC uses a 5x100 pattern. For 4, 6, or 8-lug wheels, measure center-to-center across opposite holes. For 5-lug, measure from the center of one hole to the back of the opposite hole.
What does 45mm offset mean for the 2009 tC?
An offset of 45mm means the wheel's mounting surface is 45mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Scion.
Why is matching the 54.1mm center bore important for the 2009 tC?
The 54.1mm 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.
