These are vehicle-year records whose recorded OEM ranges overlap this 2008 Ford Ranger. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 19 donor years. Listed 17 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Dataset suggestionHub-centric rings ≈ 93.1 → 70.6 mm – not a verified installation requirement.
Hub-centric rings of about 93.1 → 70.6 mm mm may be relevant if the wheel bore is larger than the hub; they cannot enlarge a smaller bore.
Recorded vehicle-side thread for the 2008 Ford Ranger is 1/2"-20UNF. This donor year is recorded as M12x1.5. That is the vehicle stud/nut thread, not an intrinsic thread stamped on the wheel. Hardware must match this vehicle’s studs and the selected wheel’s seat and engagement. Existing hardware may be reusable if it already matches. Seat style is not in this dataset, so products are not a verified fit.
Dataset suggestionWheel spacer ≈ 28.85 mm – not a verified installation requirement.
Hub-centric rings of about 93.1 → 70.6 mm mm may be relevant if the wheel bore is larger than the hub. A spacer of about 28.85 mm is a dataset suggestion only; clearance is not verified. Recorded vehicle-side thread differs (M12x1.5 on the donor year vs 1/2"-20UNF on the target vehicle). Hardware must match the target vehicle’s studs and the selected wheel’s seat. Existing hardware may be reusable if it already matches. Seat style is not confirmed in this dataset.

The specifications below are the known reference values provided for the 2008 Ford Ranger. Fitment can vary by trim, drivetrain, brake package, market, or replacement parts, so confirm the specifications for your specific truck before purchasing wheels or tires.
| Specification | Known value |
|---|---|
| Bolt pattern | 6x139.7, also written as 6x5.5 inches |
| Center bore | 70.6 mm |
| Thread size | M12 x 1.75 |
| Rim diameter | 15 inches |
| Rim width | 6.0 inches |
| Wheel offset | ET12, or 12 mm |
| Backspacing | 3.47 inches |
| Known tire size | 225/70R15 |
These values describe the supplied reference fitment and are not a guarantee that every 2008 Ford Ranger trim uses the same wheel. Confirm the original wheel markings, the vehicle certification label, the owner’s manual, and Ford service information when possible.
Use the calculator to compare a donor vehicle’s wheels with the wheels you plan to install on your 2008 Ford Ranger. Start by entering the donor vehicle in the “Wheels from” fields and your Ranger in the “Installed on” fields.
Plus sizing means using a larger wheel diameter with a lower-profile tire while attempting to keep the overall tire diameter close to the original. The supplied reference tire is 225/70R15, but no alternative wheel and tire combination is confirmed here.
Use the calculator to test proposed rim diameter, rim width, offset, tire section width, and aspect ratio. Review the calculated diameter and compare the result with the current setup. A substantially different overall diameter can affect speedometer readings, gearing, ground clearance, braking behavior, and electronic systems where applicable.
A wider wheel or tire may improve appearance or handling in some applications, but it can also increase the risk of suspension, fender, and frame interference. Do not assume that a tire size is safe solely because it fits the wheel. Confirm the tire manufacturer’s approved rim-width range and perform a complete clearance check.
A basic wheel installation should include a floor jack, properly rated jack stands, wheel chocks, a socket that fits the lug nuts, and a calibrated torque wrench. A tread-depth gauge, tire-pressure gauge, flashlight, wire brush, and measuring tools can also help with inspection and clearance checks.

Never work under a vehicle supported only by a jack. Use level ground, engage the parking brake where appropriate, chock the wheels, and support the vehicle at approved lift points.
What is the bolt pattern for the 2008 Ford Ranger?
The supplied reference bolt pattern is 6x139.7, also commonly written as 6x5.5 inches. Confirm this against the original wheel or reliable Ford service information for the specific truck.
What is the center bore?
The known reference center bore is 70.6 mm. A replacement wheel with a smaller bore will not fit over the hub. A larger bore may need a properly sized hub-centric ring when suitable for the wheel design.
What is the known original wheel and tire size?
The supplied reference wheel is 15x6.0 with ET12 offset and 3.47-inch backspacing. The supplied reference tire size is 225/70R15. Trim-specific differences have not been provided, so verify your vehicle before ordering.
Can I use any wheel with a 6x139.7 bolt pattern?
No. Bolt pattern is only one part of fitment. You must also check center bore, offset, backspacing, rim width, brake clearance, wheel load rating, fastener compatibility, and tire clearance.
How can I compare wheels from another vehicle?
Enter the donor vehicle under “Wheels from” and the 2008 Ford Ranger under “Installed on.” Compare every available measurement, then use the custom wheel and tire fields to test proposed changes. A physical test fit is still recommended.
Will changing wheel diameter change tire diameter?
Changing rim diameter requires a change in tire sidewall height if you want to maintain a similar overall tire diameter. The calculator updates the tire-diameter comparison when rim diameter is changed, but the result must still be checked against manufacturer specifications and vehicle clearance.
Do I need hub-centric rings?
Only if the wheel’s center bore is larger than the vehicle hub and the wheel manufacturer or installer determines that rings are appropriate. Rings cannot correct a wheel bore that is too small, and they do not correct an incorrect bolt pattern or offset.
Where can I confirm the final specifications?
Check the tire and loading information label, owner’s manual, original wheel markings, Ford service documentation, and the tire or wheel manufacturer’s application data. If the information conflicts, have the vehicle inspected by a qualified technician before purchasing or installing parts.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
