What is the bolt pattern for a 2017 Ram 1500?
The bolt pattern for a 2017 Ram 1500 is 6x139.7 mm (six lug holes on a 139.7 mm circle), commonly written as 6x5.5 inches.
The Ram 1500 uses a six-lug bolt arrangement on a 139.7 mm diameter circle, a standard across most Ram 1500 models. This pattern is crucial when selecting wheels or adapters. It differs from the heavy‑duty Ram 2500/3500 patterns, which typically use a different lug configuration. The rest of this article explains what that means and how to verify compatibility.
Understanding the 6x139.7 mm bolt pattern
The notation 6x139.7 mm means there are six lug holes arranged on a circle with a diameter of 139.7 millimeters. This pattern is standard for the Ram 1500 from several model years around the mid-2010s, including the 2017 model. When shopping for wheels, you must also consider center bore size, offset, and lug nut type, as those specs are separate from the bolt pattern.
Practical implications for wheels
Most aftermarket wheels labeled for the Ram 1500 are designed to fit a 6x139.7 mm bolt pattern. Ensure the wheel offset and center bore match your truck’s specs, or plan to use hub-centric rings if needed.
Quick reference: compatibility with other Ram trucks
Here’s how this bolt pattern interacts with other Ram models:
- 6x139.7 mm bolt pattern applies to the Ram 1500 family, including the 2017 model, and several other late-model 1500s.
- Heavy‑duty Ram 2500/3500 trucks typically use a different lug pattern (often 8x165.1 mm), so wheels from a 1500 may not fit those trucks without adapters or hub changes.
In short, the 2017 Ram 1500 shares the 6x139.7 mm bolt pattern with most light-duty Ram 1500s, making wheel compatibility largely a matter of offset and center bore rather than lug count.
Verification tips
To confirm the bolt pattern before purchase, check the vehicle’s manual or the placard on the driver’s door jamb, and measure if needed. Steps include counting lug holes, measuring the lug circle diameter, and verifying the center bore.
- Count lug holes: 6
- Measure bolt circle diameter: 139.7 mm (5.5 inches)
- Check center bore size and lug nut type separately
When in doubt, consult the wheel manufacturer or a professional shop to ensure the wheels you select will fit your 2017 Ram 1500 correctly.
Summary
The 2017 Ram 1500 uses a 6x139.7 mm bolt pattern (6 on 139.7 mm circle, or 6x5.5 inches). This is standard for the Ram 1500 lineup of that era and is the primary factor for wheel compatibility, along with center bore, offset, and lug nut specifications. Always verify all related specs with the seller or a qualified technician before purchasing wheels.
