What is the bolt pattern on a 2008 Dodge Ram 4500?
The bolt pattern for a 2008 Dodge Ram 4500 is 8 on 6.5 inches (8x165.1 mm).
This means eight lug holes are arranged on a circle with a diameter of 6.5 inches (165.1 mm). The Ram 4500, part of Dodge's heavy‑duty lineup from that era, generally uses this same eight‑lug pattern as other heavyweight Ram models, which influences wheel compatibility and aftermarket options. When swapping wheels, it’s important to consider not only the bolt pattern but also hub bore size and lug nut type to ensure a proper fit.
Bolt pattern basics
Understanding bolt pattern helps determine whether a wheel will mount on a vehicle. The pattern is defined by two factors: the number of lug holes and the bolt circle diameter (the circle formed by the centers of the lug holes).
What the numbers mean
8x165.1 mm means eight lug holes spaced around a circle that is 165.1 millimeters in diameter. In common U.S. wheel terminology, this is described as 8x6.5 inches. This pattern is typical of Dodge Ram heavy‑duty trucks from the mid‑2000s era and is a key compatibility factor when sourcing wheels or adapters.
Ram 4500 specifics
For the 2008 Ram 4500, the eight‑lug, 6.5‑inch pattern is standard. The pattern is shared with many Ram 2500/3500 models from roughly the same generation, which simplifies cross‑model wheel compatibility for many aftermarket options. Prospective buyers should still verify other fit details such as center bore size and lug nut type to ensure a precise, secure mount.
Compatibility with other Ram models
Because the Ram heavy‑duty lineup often used the same 8x165.1 mm bolt pattern, wheels sourced for a 2500 or 3500 from that era can sometimes fit a 4500. However, variations in hub bore size and seat style (the shape of the lug nut seat) can affect fit, so always confirm these aspects before purchase.
Verifying wheel compatibility
When shopping for wheels or tires, verify the following to ensure proper fitment on a 2008 Ram 4500:
Quick checklist
- Bolt pattern: confirm 8x165.1 mm (8x6.5 inches) on the wheel or vehicle specification.
- Hub bore: ensure the wheel’s center bore matches or is larger than the vehicle’s hub bore.
- Lug nut seat and thread size: match the lug nut type and thread to the vehicle’s lug studs.
- Wheel offset and width: ensure the wheel’s offset and width won’t cause rubbing or clearance issues with suspension, brakes, or fenders.
Summary
In brief, the 2008 Dodge Ram 4500 uses an 8x165.1 mm (8 on 6.5 inches) bolt pattern. This pattern is common among Ram heavy‑duty models of that era, but full wheel compatibility depends on additional factors like hub bore size, lug nut seat type, offset, and width. Always verify these details with the wheel manufacturer or your vehicle’s specifications before purchasing wheels or adapters.
