What trucks have an 8x170 bolt pattern?
Eight-lug wheels on a 170 mm (6.69 inches) bolt circle are relatively rare in modern light-duty trucks. In practice, you’ll find this pattern on a small set of heavy-duty and commercial vehicles rather than mainstream pickups. This article outlines where the pattern appears, how to identify it on a vehicle, and what to consider if you’re shopping for wheels or adapters.
Understanding the 8x170 bolt pattern
The 8x170 bolt pattern means there are eight lug holes arranged on a circle with a 170 millimeter diameter. In common wheel notation this is also described as 8 on 170 mm or 8x6.69 inches. Because it’s less common than patterns like 8x165.1 or 6x139.7, it tends to show up on heavier-duty platforms or regions with different fleet specifications. Correct identification is essential for safety, brake clearance, and hub compatibility.
Where this pattern appears in the market
Below is a broad overview of the kinds of trucks that have been documented to use an 8x170 bolt pattern. The exact model-year applicability can vary by market, manufacturing era, and axle configuration. Always verify with official specifications before purchasing wheels or adapters.
- Heavy-duty pickups and chassis-cab vehicles used in construction, utilities, and fleet operations, where eight lug wheels are standard for load and durability.
- Medium- to heavy-duty commercial trucks from global manufacturers (in select regions) that sit on international or fleet-oriented platforms, where wheel patterns can differ by model and axle arrangement.
- Specialty expedition or off-road configurations built on heavy-duty frames and commonly found in custom or aftermarket projects, where 8-lug wheels are employed for strength and compatibility with large braking systems.
Because this pattern is not common in mainstream consumer trucks, model-year availability is highly specific to region and configuration. If you’re unsure whether a particular vehicle uses 8x170, confirm with the manufacturer or a trusted wheel supplier before buying wheels or adapters.
How to confirm 8x170 on your vehicle
- Check the vehicle’s door jamb data plate or owner’s manual for the wheel pattern specification (eight lugs on a 170 mm circle).
- Examine the wheel hub and lug pattern directly with a caliper, ruler, or lug pattern gauge, comparing the measurement to 170 mm or 6.69 inches.
- Look up the VIN/build sheet or check the service/parts catalog for the exact wheel specification by model-year and axle configuration.
- Contact the dealer or OEM fleet specialist to confirm whether your specific truck model-year uses 8x170 on any axle.
- If considering wheels from aftermarket vendors, ensure they are rated for the vehicle’s load, brake clearance, and hub bore; verify compatibility with any adapters and the vehicle’s braking system.
Following these steps helps ensure a proper fit and safe operation. If you plan to change wheels, always prioritize correct lug pattern, hub bore, center bore alignment, and load ratings.
Additional considerations
Because the 8x170 pattern is not widely standardized across the broader light-truck market, aftermarket support for wheels and adapters tends to be limited compared with more common patterns. Always rely on official specifications and professional installation when dealing with heavy-duty hardware to maintain safety and performance.
Summary
The 8x170 bolt pattern is a niche specification, appearing primarily on certain heavy-duty and commercial trucks rather than mainstream pickups. To determine if a particular model-year uses 8x170, consult the OEM specifications, VIN/build data, and reputable wheel vendors. If you do encounter this pattern, ensure precise matching of lug count, bolt circle diameter, center bore, and load rating to maintain proper fit and safety. For most buyers and installers, confirmation with the manufacturer is the best path to a reliable wheel solution.
