What is the Dodge 6 lug bolt pattern?
The Dodge 6-lug bolt pattern is most commonly 6x139.7 mm (6 on 5.5 inches). This spacing is standard on many Ram pickups and related vehicles, though exact specs can vary by model year, so always verify before buying wheels or adapters.
Pattern basics
In automotive terms, the bolt pattern describes how many lug studs a wheel uses (six) and the diameter of the circle those studs form on the hub (139.7 millimeters, or 5.5 inches). On Dodge Ram trucks, the most widely used six-lug configuration is 6x139.7 mm. This is the same pattern used by many other brands, which is why many aftermarket wheels list "6x139.7" or "6x5.5" as compatibility. However, some older or specialty models may have different specs, so confirm for your specific year/model.
Common Dodge 6-lug configuration
Below is the primary pattern you’re most likely to encounter when dealing with Dodge wheels and upgrades. This helps you identify compatibility at a glance.
- 6x139.7 mm (6 on 5.5 inches) bolt circle; the standard for most Ram 1500, 2500, and 3500 pickups across several generations.
When planning a wheel upgrade or a tire swap, sticking to this pattern minimizes the need for adapters. Always verify the wheel specs for hub bore compatibility and offset to ensure a proper fit.
How to verify your Dodge bolt pattern
To be sure you’ve got the right bolt pattern, you can measure or check official specs. Here are practical steps to confirm quickly.
- Count the number of lug studs on your wheel hub (six for the Dodge six-lug pattern).
- Measure the bolt circle diameter (PCD) by measuring the distance between the centers of two opposite lug holes; convert to millimeters if needed. For Dodge Ram patterns, this is typically 139.7 mm (5.5 inches).
- Check the wheel center bore size to ensure hub-centric fitment, and review wheel offset/backspacing to maintain proper clearance.
- Cross-check your exact model year with a reliable parts catalog or dealership to account for any minor variations.
With these checks, you’ll determine whether a wheel will fit without modifications or if you’ll need adapters or a different wheel choice.
