What other years of Ram 3500 Mega Cab have the same bolt pattern as the 2017?
The Ram 3500 Mega Cab uses the 8x165.1 pattern from 2011 through 2024. Wheels from any of these model years are dimensionally compatible with the 2017, provided the offset and center bore also match.
What is the center bore of a 2017 Ram 3500 Mega Cab?
The factory center bore (hub bore) for the 2017 Ram 3500 Mega Cab is 121.3mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
Will wheels from another Ram fit my 2017 3500 Mega Cab?
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 2017 3500 Mega Cab?
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.

Absolutely. Just ensure the aftermarket wheels have a 8x165.1 bolt pattern, an offset near 43mm, and a center bore of at least 121.3mm (using hub rings if larger).
