Ford F-250 Wheel Bolt Pattern Guide: 2015, 2017 and 2019
Direct Answer
For the 2015, 2017 and 2019 Ford F-250, the wheel bolt pattern is 8x170 millimeters. This means the wheel has eight lug holes arranged in a circle with a diameter of 170 millimeters. That specification applies to the standard single rear wheel configurations for these model years. The number is often written as 8x170 or 8 on 170.
What the 8x170 Measurement Means
A wheel bolt pattern is described by two figures. The first figure is the number of wheel studs or lug holes. An F-250 has eight. The second figure is the pitch circle diameter, measured in millimeters. It is the diameter of an imaginary circle that passes through the center of each stud or hole. For this truck, that circle is 170 millimeters across.
This measurement is not a simple distance between two adjacent studs. Because the studs are not evenly spaced across a straight line in a way that matches the circle, measuring from one stud to another directly will give a different number. The correct approach uses the full circle through all eight stud centers.
Why the Pattern Can Confuse
An 8x170 pattern is less common than the 8x165.1 pattern used on some older Ford trucks and many other heavy-duty pickups. That difference of about 5 millimeters is small enough that wheels may appear close, but they are not interchangeable. Any replacement wheel must match the 8x170 specification exactly.
Model Year Context
The 2015 F-250 belongs to the later part of the second-generation Super Duty platform that used the 8x170 pattern. The 2017 F-250 was part of a significant update, and the 2019 F-250 continued that updated generation. Across these three model years, the 8x170 bolt pattern remains consistent for single rear wheel models.
Dual rear wheel configurations are a separate matter. An F-250 is typically a single rear wheel truck. If a chassis cab or other special configuration is being considered, the wheel specification should be confirmed from the vehicle's door jamb label or owner's manual because commercial and fleet variants can differ.
Additional Wheel Specifications
Knowing the bolt pattern is necessary but not sufficient when selecting wheels. Center bore, offset, backspacing and load rating also determine fitment. The center bore is the large hole in the middle of the wheel that centers it on the hub. A mismatch there can prevent mounting even when the bolt pattern is correct.
Torque specifications for the lug nuts should follow the manufacturer's recommended sequence and value. Applying uneven torque can distort brake rotors and cause vibration. For an F-250, the owner's manual provides the exact figure, which is typically higher than for a light-duty passenger vehicle.
How to Verify the Pattern Yourself
If a wheel is already removed, the stud count is easy to see. The pitch circle diameter can be measured with a bolt pattern gauge or a precise ruler. For an eight-lug wheel, measuring from the center of one stud to the center of the stud directly across the hub gives the circle diameter, which should read very close to 170 millimeters.
If the wheel is mounted, the same principle applies using the visible lug nuts. They should follow the same 170-millimeter circle. If any measurement deviates by more than a small allowance, the wheel may be from a different application despite a similar appearance.
What to Check Before Buying Wheels
A replacement wheel should list the 8x170 bolt pattern explicitly. It should also be rated for the gross axle weight of the F-250. Wheels designed for lighter trucks may share the same bolt pattern location but lack the load capacity required by a heavy-duty pickup.
OEM take-off wheels from another 2015, 2017 or 2019 F-250 are generally a direct fit within the same single rear wheel configuration. Aftermarket wheels require closer attention to center bore and offset because those dimensions affect steering geometry, clearance and hub centering.
Material Gaps
This guide does not provide a single center bore measurement because that figure can depend on the wheel's intended application and aftermarket design. It also does not state a universal lug nut torque value because exact figures vary by model year and axle configuration. Those numbers should be taken from the vehicle's specific documentation or door jamb label.
