2025 Ram ROAD TRAMPS MC — Frequently Asked Questions
What is the bolt pattern for a 2025 Ram ROAD TRAMPS MC?
The 2025 Ram ROAD TRAMPS MC uses a 6x139.7 bolt pattern (also called lug pattern or PCD). The center bore is 77.8mm and the offset is 18-25mm.
What other years of Ram ROAD TRAMPS MC have the same bolt pattern as the 2025?
The Ram ROAD TRAMPS MC uses the 6x139.7 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.
What is the factory wheel offset for a 2025 Ram ROAD TRAMPS MC?
The OEM offset for the 2025 ROAD TRAMPS MC is typically around 18-25mm. Depending on wheel width, a deviation of ±5mm is usually acceptable, but verify suspension clearance.
What does 18-25mm offset mean for the 2025 ROAD TRAMPS MC?
An offset of 18-25mm means the wheel's mounting surface is 18-25mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Ram.
Why is matching the 77.8mm center bore important for the 2025 ROAD TRAMPS MC?
The 77.8mm 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.
How do I measure the bolt pattern on my 2025 Ram?
The 2025 ROAD TRAMPS MC uses a 6x139.7 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.
