Are Chevy and Dodge 8 lug bolt patterns the same?
In short: no. Chevy/GM heavy-duty trucks typically use an 8x6.5" bolt pattern, while Ram (Dodge) heavy-duty trucks use an 8x6.0" bolt pattern. The two patterns are not interchangeable without adapters or modifications.
Bolt pattern basics
Understanding eight-lug patterns starts with the number of lug holes and the bolt circle diameter. GM’s heavy‑duty line commonly uses 8 bolts on a 6.5-inch circle (8x6.5"), while Ram’s heavy‑duty line uses 8 bolts on a 6.0-inch circle (8x6.0"). Because the circle diameters differ, the lug holes do not align between the brands, meaning wheels aren’t directly compatible simply by swapping patterns.
What this means in practice is that you cannot simply bolt a GM eight-lug wheel onto a Ram hub, or vice versa, without considering hub and center bore geometry, as well as brake and caliper clearance.
- Chevy/GM heavy-duty pattern: 8x6.5" (8 lug holes on a 6.5" bolt circle; about 165 mm in diameter). This pattern is common on Chevrolet Silverado and GMC Sierra 2500HD/3500HD models.
- Dodge/RAM heavy-duty pattern: 8x6.0" (8 lug holes on a 6.0" bolt circle; about 152 mm in diameter). This pattern is common on Ram 2500/3500 models.
These two patterns are not interchangeable, and attempting to mix wheels can lead to unsafe fitment, improper seating, or structural failure under load.
Interchangeability and considerations
If you are considering swapping wheels between GM and Ram or using adapters, here are the key factors to assess:
- Bolt-circle mismatch: An 8x6.5" wheel will not bolt onto an 8x6.0" hub without an adapter, and even with an adapter the mounting alignment and hub engagement can be compromised.
- Hub-centric vs. lug-centric fitment: Differences in center bore and hub engagement can cause vibration or improper seating if not matched or properly corrected with rings/adapters.
- Brake and caliper clearance: Wheels must clear calipers, rotors, and knuckles. Some wheels may not clear heavy-duty brakes on Ram or GM trucks even if the lug pattern matches.
- Load ratings and torque specs: Adapters and cross-brand wheels may have different load ratings or torque requirements. Use parts rated for the vehicle’s load and torque specs.
- Warranty and safety considerations: Using adapters or non-OEM wheels can affect warranties and may raise safety or regulatory concerns. Check with the dealer or manufacturer before proceeding.
If you must pursue cross-brand wheel usage, consult a qualified shop to select approved adapters that preserve hub-centric fitment and braking clearance, and ensure proper torque, wheel studs, and lug nuts are used.
Summary
The short answer is no: Chevy/GM eight-lug patterns (8x6.5") are different from Dodge/Ram eight-lug patterns (8x6.0"). They require wheels that match the vehicle's bolt circle and center bore, or the use of carefully engineered adapters with professional installation. Always verify fitment for the specific year, model, and trim of your vehicle.
Do Chevy and Ram have the same bolt pattern?
Yes they do. Bolt pattern is the same, back spacing is very similar.
Will a Chevy 8 lug fit a Dodge?
Will Chevy 8 lug wheels fit Ford or dodge? Yes if the Ford is pre 1998. After that, they switched to a different bolt pattern. Dodge and GM still use the same pattern unless it's a 2013 and up GM.
What bolt pattern is the Dodge 8 lug?
Bolt Pattern Chart
| TRUCK | YEAR | BOLT CIRCLE |
|---|---|---|
| Dodge Ram 3/4-ton | 14-Current | 8X6.5 |
| Dodge Ram 1-ton Pickup (Single & Dual) | 69-93 | 8X6.5 |
| Dodge Ram 1-ton Pickup (Single & Dual) | 94-11 | 8X6.5 |
| Dodge Ram 1-ton Pickup (Single & Dual) | 12-18 | 8X6.5 |
Will Chevy lug nuts fit a Dodge?
Most Dodge and Chevy vehicles use steel wheel nuts. The most common thread sizes that are used by Dodge and Chevy cars are M14x1.
