Bolt pattern basics for the 2nd-generation Ram
The second generation of Ram heavy-duty trucks, produced from 2009 through 2018, uses an eight-lug wheel pattern. Understanding the pattern helps when selecting wheels, tires, or performing aftermarket upgrades.
Key specifications you should know before buying wheels or performing a swap:
- Lug count: 8
- Bolt circle diameter: 165.1 mm (6.5 inches)
- Applicable models: Ram 2500 and Ram 3500, 2009–2018, including both SRW and DRW variants
- Fitment caveats: verify hub bore size and wheel offset/backspacing; some aftermarket wheels may require center rings or specific spacers
In short, the standard bolt pattern for the 2nd-generation Ram 3500 remains 8x165.1 mm, and this tends to be consistent across both SRW and DRW configurations. Always confirm hub bore and offset requirements with the wheel manufacturer before purchasing.
SRW vs DRW compatibility
Both single-rear-wheel (SRW) and dual-rear-wheel (DRW) versions of the 2nd-generation Ram 2500/3500 use the same 8x165.1 mm bolt pattern. However, DRW wheels often have different center bores and backspacing, so verify fitment and use any required rings or adapters as needed.
Summary
The 2nd-generation Dodge Ram 3500 (2009–2018) uses an 8x165.1 mm bolt pattern, applicable to both SRW and DRW configurations. When swapping wheels, always check hub bore, offset, and center bore requirements to ensure a proper, safe fit.
