What trucks use the 8x6.5 bolt pattern?
The 8x6.5 bolt pattern is most commonly found on General Motors’ heavy‑duty lineup, including 3/4‑ton and 1‑ton pickups and their large SUVs and vans.
GM heavy‑duty pickups
This section covers GM’s 3/4‑ton and 1‑ton pickups, where the 8x6.5 pattern is most consistently used across many generations and configurations.
- Chevrolet Silverado 2500HD
- Chevrolet Silverado 3500HD
- GMC Sierra 2500HD
- GMC Sierra 3500HD
The core of GM’s 8x6.5 lineup lies with these heavy‑duty trucks, which are frequently paired with heavy‑duty suspensions, gooseneck/tow packages, and extended cabs or crew cab configurations. Always confirm year‑by‑year compatibility, as there can be minor variations in hub bore size or lug thread spec.
GM full‑size SUVs
This section highlights large GM SUVs that commonly use the 8x6.5 pattern in their heavier‑duty variants, linking them to the same wheel family as the pickups above.
- Chevrolet Suburban
- GMC Yukon
- GMC Yukon XL
- Chevrolet Tahoe (heavier‑duty configurations)
Note: not every generation or every trim of these SUVs uses 8x6.5. Lighter‑duty variants (where applicable) may rely on a different lug pattern. Always verify with a model‑year specific specification or by measuring the pattern on the vehicle.
GM vans
GM’s large cargo vans have also commonly used the 8x6.5 bolt pattern, making this lug arrangement a familiar standard for commercial and conversion applications.
- Chevrolet Express 2500/3500
- GMC Savana 2500/3500
Vans in this category often share the same 8x6.5 lug circle across multiple model years, though some early or specialty configurations can differ slightly. When shopping for wheels or adapters, confirm the exact bolt pattern, center bore, and thread‑pitch for your vehicle year and trim.
Summary
In practice, if you’re dealing with GM’s heavy‑duty lineup—3/4‑ton and 1‑ton pickups, full‑size SUVs on the heavy‑duty platform, or GM’s large vans—you’ll frequently encounter the 8x6.5 bolt pattern. Light‑duty 1500 GM trucks typically use a 6x139.7 mm (6x5.5 in) pattern, which is a key distinction when planning wheels or upgrades. Always verify pattern specifics for your exact year and model before purchasing wheels or adapters.
What trucks use an 8x6 5 lug pattern?
Trucks with an 8x6.5 bolt pattern include many older and some current heavy-duty models from Ford, Dodge, Chevy, and GMC, such as the Ford F-250 and F-350 (up to 1998), Dodge Ram 2500 and 3500 (up to 2010), and many 2500/3500 series Chevrolet and GMC trucks (up to 2010). The bolt pattern is also found on various heavy-duty vans and some Cadillac models.

Will 8x6.5 fit F250?
An 8x6.5 bolt pattern will not directly fit most modern F-250s, which changed to an 8x170mm bolt pattern in 1999. However, if your F-250 has the older 8x6.5 bolt pattern (pre-1999) or if you use adapters, the 8x6.5 wheels can be fitted.
For modern F-250s (1999 and newer)
- Bolt pattern: You need an adapter to convert the 8x170mm bolt pattern to 8x6.5.
- Adapters: You will need to use an adapter, which is a device that bolts to the vehicle's wheel hub and has a new bolt pattern on the other side.
- Center bore: Be sure to check that the adapter's center bore is compatible with your truck's hub, as the original Ford Super Duty has a larger center bore than many other vehicles with an 8x6.5 bolt pattern, like some GM trucks.
- Offset: The adapter will affect the wheel's offset, so you will need to check for potential clearance issues with your truck's suspension and brake components.
For older F-250s (pre-1999)
- Bolt pattern: The 8x6.5 bolt pattern is standard for this model year.
- Center bore: While the bolt pattern is the same, the center bore of aftermarket wheels with an 8x6.5 bolt pattern is generally large enough to fit the F-250's hub.
- Offset: The offset may still need to be checked for clearance, but it's less likely to be an issue compared to aftermarket wheels designed for different trucks.
