These are vehicle-year records whose recorded OEM ranges overlap this 2002 GMC Safari. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 16 donor years. Listed 16 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.
Approximate position vs the mid OEM package: outer change -6.68 mm, inner change 0.33 mm. This uses aggregated width/offset ranges, not a specific wheel.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Recorded vehicle-side thread for the 2002 GMC Safari is 1/2"-20UNF. This donor year is recorded as M14x1.5. 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 ≈ 27.68 mm – not a verified installation requirement.
A spacer of about 27.68 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 27.68 mm farther inward than the mid OEM package. Recorded vehicle-side thread differs (M14x1.5 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.

Recorded vehicle-side thread for the 2002 GMC Safari 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 suggestionHub-centric rings ≈ 100.3 → 78.3 mm – not a verified installation requirement.
Hub-centric rings of about 100.3 → 78.3 mm mm may be relevant if the wheel bore is larger than the hub; clearance is not verified. Donor width/offset sits outside the known OEM envelope for this vehicle.

Dataset suggestionHub-centric rings ≈ 100.3 → 78.3 mm – not a verified installation requirement.
Hub-centric rings of about 100.3 → 78.3 mm mm may be relevant if the wheel bore is larger than the hub; they cannot enlarge a smaller bore. 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. Width/offset ranges overlap; confirm diameter and brake clearance for your trim.

Use the calculator below to compare wheels from another vehicle against your 2002 GMC Safari, or check compatible donor vehicles that share the same bolt pattern and center bore.
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.
