Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.

Center-bore records disagree: year-level hub 78.1 mm vs trim range 70.3–70.3 mm. Interchange below does not treat this as an unqualified match.

Donor vehicles with overlapping OEM specs

These are vehicle-year records whose recorded OEM ranges overlap this 1999 GMC Envoy. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.

Evaluated 10 donor years. Listed 10 eligible overlaps (not all evaluated years are compatible). Showing all listed.

Check wheel configurationCenter-bore records disagree
  • Bolt pattern5x120.65 · Same recorded PCD
  • Center bore70.3 mm · same recorded hub figure
  • Wheel geometryOEM width/offset ranges overlap (not a specific wheel)

Center-bore records disagree (target year-level hub 78.1 mm vs trim range 70.3–70.3 mm; donor year-level hub 78.1 mm vs trim range 70.3–70.3 mm). Unqualified overlap is not claimed until the conflict is resolved. Approximate position vs the mid OEM package: outer change -0.67 mm, inner change -5.68 mm. This uses aggregated width/offset ranges, not a specific wheel.

Use the calculator below to compare wheels from another vehicle against your 1999 GMC Envoy, 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
  • Lug thread / hardware differences (vehicle-side hardware)

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.
