Expert Buying Guide for 2004 Scion xA
For the 2004 Scion xA, the 4x100 bolt pattern is shared with many Honda and Toyota models, but the 54.1mm center bore is unique. Aftermarket wheels often have a larger bore (e.g., 56.1mm or 73.1mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. The offset range is tight: 35-45mm. Going outside this range may cause rubbing on suspension or fenders. Always use M12x1.5 lug nuts with the correct seat type—factory wheels use a conical (60-degree) seat, while aftermarket wheels may require ball-seat or shank-style nuts. Never mix seat types; improper engagement can lead to wheel loss. Verify lug nut length to avoid bottoming out on studs.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to account for wheel settling.
- ✅ If using aftermarket wheels, ensure hub-centric rings are made of metal (not plastic) for durability.
- ✅ Check for caliper clearance: some 15-inch wheels may not clear the front brake calipers on the xA.
- ⚠️ Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- ⚠️ This fitment uses a wide offset range. Check brake clearance and fender clearance before buying wheels.
- ⚠️ Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).

2004 Scion xA — Frequently Asked Questions
What is the bolt pattern for a 2004 Scion xA?
The 2004 Scion xA uses a 4x100 bolt pattern (also called lug pattern or PCD). The center bore is 54.1mm and the offset is 35-45mmmm.
What other years of Scion xA have the same bolt pattern as the 2004?
The Scion xA uses the 4x100 pattern from 2004 through 2006. Wheels from any of these model years are dimensionally compatible with the 2004, provided the offset and center bore also match.
How tight should I torque the lug nuts on a 2004 Scion xA?
Refer to your owner's manual for exact specs, but always tighten the M12x1.5 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
What does 35-45mmmm offset mean for the 2004 xA?
An offset of 35-45mmmm means the wheel's mounting surface is 35-45mmmm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Scion.
Will wheels from another Scion fit my 2004 xA?
Only if they share the exact same 4x100 bolt pattern, a compatible offset, and a center bore equal to or larger than 54.1mm.
How do I measure the bolt pattern on my 2004 Scion?
The 2004 xA uses a 4x100 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.
