Overview
The 4 Wheel Parts Factory S-Series wheel, part number 4WP8018-218345, is a 20 x 10-inch aluminum wheel with 3D mesh styling and a gloss black milled finish. It has a 6 on 5.5 bolt pattern, an offset of -24 and a backspacing of 4.5.
The S-Series is a street wheel with milled accents for trucks and Jeeps. Confirm the bolt pattern and offset yourself before buying, since those numbers decide whether the wheel clears your hubs.
The -24 offset places the mounting face outboard of the wheel’s center, so this wheel sits further out than a zero-offset design. A 6 on 5.5 pattern uses six lugs on a 5.5 bolt circle, and the hub must match exactly. The 4.5 backspacing governs the inner lip’s position, which matters for brake and suspension clearance. The gloss black milled finish and 3D mesh styling are the design features 4 Wheel Parts highlights in its S-Series line, which it describes as a street look for larger tires.

Offset and clearance basics
Offset is the distance from the wheel’s mounting face to its centerline, and it decides how far the wheel sits in the fender. A wheel with more negative offset pushes the tire outward, which can change steering feel and clearance to the fender. Backspacing works the other way, controlling how close the inner lip comes to suspension and brake parts.
A 20-inch wheel usually pairs with a lower-profile tire, which can make the ride firmer and leaves less sidewall to absorb impacts. Mesh designs with milled accents collect dirt in the gaps, so plan on cleaning them after trail use. Check fender liners and brake calipers for rub after any change in wheel size or offset.
- Measure fender clearance before buying
- Match tire profile to the wheel
- Inspect for rub after install
