Expert Buying Guide for 2018 FIAT 500 Abarth
For your 2018 FIAT 500 Abarth, the 4x98 bolt pattern and 58.1mm center bore are critical. Aftermarket wheels often have a larger bore (e.g., 73.1mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. Offset is sensitive; the stock 35mm offset maintains scrub radius and clearance. Deviating more than ±5mm may cause rubbing or handling issues. Always use 12x1.25 lug nuts with the correct seat (cone or ball) matching the wheel. Improper seating can lead to wheel loosening. Re-torque after 50-100 miles.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 85-95 ft-lbs after 50-100 miles of driving.
- ✅ If using aftermarket wheels, verify hub-centric ring inner diameter matches 58.1mm and outer diameter matches wheel bore.
- ✅ Avoid spacers; they alter offset and may require longer studs, risking hub engagement.
- ⚠️ 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 bolt pattern is less common in our dataset. Verify wheel availability and hub specs before ordering.

2018 FIAT 500 Abarth — Frequently Asked Questions
What is the bolt pattern for a 2018 FIAT 500 Abarth?
The 2018 FIAT 500 Abarth uses a 4x98 bolt pattern (also called lug pattern or PCD). The center bore is 58.1mm and the offset is 35mm.
What other years of FIAT 500 Abarth have the same bolt pattern as the 2018?
The FIAT 500 Abarth uses the 4x98 pattern from 2014 through 2019. Wheels from any of these model years are dimensionally compatible with the 2018, provided the offset and center bore also match.
What is the factory wheel offset for a 2018 FIAT 500 Abarth?
The OEM offset for the 2018 500 Abarth is typically around 35mm. Depending on wheel width, a deviation of ±5mm is usually acceptable, but verify suspension clearance.
What is the center bore of a 2018 FIAT 500 Abarth?
The factory center bore (hub bore) for the 2018 FIAT 500 Abarth is 58.1mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
What is the PCD for a 2018 FIAT 500 Abarth?
PCD stands for Pitch Circle Diameter, which is the same as the bolt pattern. For the 2018 500 Abarth, the PCD is 4x98.
What does 35mm offset mean for the 2018 500 Abarth?
An offset of 35mm means the wheel's mounting surface is 35mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your FIAT.
