2025 Ram 4500 — Frequently Asked Questions
What is the bolt pattern for a 2025 Ram 4500?
The 2025 Ram 4500 uses a 8x165.1 bolt pattern (also called lug pattern or PCD). The center bore is 121.3mm and the offset is Not Applicablemm.
What other years of Ram 4500 have the same bolt pattern as the 2025?
The Ram 4500 uses the 8x165.1 pattern from 2024 through 2025. Wheels from any of these model years are dimensionally compatible with the 2025, provided the offset and center bore also match.
Will wheels from another Ram fit my 2025 4500?
Only if they share the exact same 8x165.1 bolt pattern, a compatible offset, and a center bore equal to or larger than 121.3mm.
Why is matching the 121.3mm center bore important for the 2025 4500?
The 121.3mm 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 use spacers on my 2025 Ram 4500?
Yes, but ensure the wheel spacers match the 8x165.1 bolt pattern and 121.3mm center bore. Also verify that you have enough thread engagement for your 14x1.5 hardware.
What does Not Applicablemm offset mean for the 2025 4500?
An offset of Not Applicablemm means the wheel's mounting surface is Not Applicablemm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Ram.
