What vehicle is 8x170 bolt pattern?
The 8x170 bolt pattern is a rare lug arrangement most commonly associated with Ford’s heavy‑duty trucks and a classic SUV. The primary vehicles that use this pattern are the Ford F-250 and F-350 Super Duty pickups, along with the Ford Excursion.
In practice, a bolt pattern describes how many lug holes are on a wheel and the diameter of the circle those holes form. An 8x170 pattern means eight lug holes arranged on a 170 mm circle. This pattern is not used by most passenger cars, but it is common in certain Ford heavy‑duty trucks and SUVs from the late 1990s onward. Always verify with your vehicle’s specifications or a reliable wheel catalog, as year‑by‑year changes can occur.

Tips for buying wheels with 8x170
Before shopping for wheels, here are key considerations to ensure compatibility and safety.
- Verify the bolt pattern and center bore: 8x170 means eight lug holes on a 170 mm circle, and the center bore must match or be larger than the hub to avoid hub‑centric fit issues.
- Check wheel width and offset: heavy‑duty trucks require appropriate width and offset to maintain proper clearance with brakes, fenders, and suspension.
- Consider rotor/drum compatibility: some wheels require hub‑centric spacers or flanges; verify rotor diameter compatibility with caliper clearance.
- Confirm load rating: ensure wheels have adequate load rating for HD trucks and any payload you carry.
Ensuring compatibility with your exact year/model is essential since Ford’s 8x170 pattern has appeared on multiple iterations of the Super Duty line and related SUVs across different generations.
Summary
The 8x170 bolt pattern is predominantly found on Ford's heavy‑duty lineup—specifically the F-250 and F-350 Super Duty pickups and the classic Ford Excursion, with some variants and years offering the same lug arrangement. When in doubt, consult the owner’s manual, a dealership, or a trusted wheel retailer to confirm compatibility for your vehicle and intended wheels.
