Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2021 RAM ProMaster 1500. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 5 donor years. Listed 5 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Insufficient dataCheck lug hardware: donor year M16x1.5 vs 2021 RAM ProMaster 1500 M16x1.50
Bolt pattern5x130 · Same recorded PCD
Center bore78.1 mm · same recorded hub figure
Wheel geometryNot fully recorded
Recorded vehicle-side thread for the 2021 RAM ProMaster 1500 is M16x1.50. This donor year is recorded as M16x1.5. 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.

Use the calculator below to compare wheels from another vehicle against your 2021 RAM ProMaster 1500, or check compatible donor vehicles that share the same bolt pattern and center bore.
Fitment Basics
Always confirm center bore matches your hub, or use hub-centric rings to take up the gap.
Check offset carefully – wheels that stick out too far can rub on fenders or suspension components.
Verify thread size and lug type before buying replacement bolts or lug nuts.
When in doubt, use the calculator below to compare exact specs side by side.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
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.
