Expert Buying Guide for 2018 FIAT 500
For your 2018 FIAT 500, 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. The stock offset is 35mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always use the correct 12x1.25 lug nuts with a conical (60-degree) or ball seat—mixing seat types can lead to wheel loosening. Verify that aftermarket wheels are hub-centric or use rings, and check offset compatibility to avoid suspension or brake interference.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 85-95 ft-lbs after 50 miles of driving to account for settling.
- ✅ Avoid using universal lug nuts; they may not seat properly on the 12x1.25 studs.
- ✅ If installing wider wheels, test fitment with the suspension fully compressed to check for rubbing.
- ⚠️ 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 — Frequently Asked Questions
What is the bolt pattern for a 2018 FIAT 500?
The 2018 FIAT 500 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 have the same bolt pattern as the 2018?
The FIAT 500 uses the 4x98 pattern from 2012 through 2019. Wheels from any of these model years are dimensionally compatible with the 2018, provided the offset and center bore also match.
What lug nut size does the 2018 FIAT 500 use?
The 2018 FIAT 500 uses 12x1.25 lug nuts. Always verify the thread pitch and seat type (cone, ball, or flat) match your aftermarket wheels.
What does 35mm offset mean for the 2018 500?
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.
Why is matching the 58.1mm center bore important for the 2018 500?
The 58.1mm 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.
Can I put aftermarket wheels on my 2018 FIAT 500?
Absolutely. Just ensure the aftermarket wheels have a 4x98 bolt pattern, an offset near 35mm, and a center bore of at least 58.1mm (using hub rings if larger).
