These are vehicle-year records whose recorded OEM ranges overlap this 2020 Acura ILX. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 77 donor years. Listed 24 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.
Recorded OEM bolt pattern, center bore, and width/offset ranges overlap. This is not a guarantee that every wheel from the donor year fits this vehicle.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -3.85 mm, inner change -8.85 mm. This uses aggregated width/offset ranges, not a specific wheel.

You need safe, correct wheel fitment for a 2020 Acura ILX without guessing specifications.
This guide shows how to verify OEM fitment, test alternate wheels, and use the on-page calculator for validation.
You should have basic hand tools, a torque wrench, and access to the vehicle or reliable OEM documentation.
Know that some values vary by trim or aftermarket options. Where values are not listed, I explain how to confirm them.
| OEM spec | Value |
|---|---|
| Bolt pattern (studs x PCD) | 5x114.3 |
| Center bore (mm) | 64.1 |
| Thread size | M12 x 1.5 |
| Rim diameter (in) | 17 |
| Rim width (in) | 7.0 |
| Wheel offset (ET, mm) | 50 |
| Backspacing (in) | 5.47 |
| Tire size (section/ratio/R) | 215 / 45 / R17 |
Start with the problem: will a new or donor wheel mount correctly without interference or safety risk.
Confirm the basic match. Check that the donor wheel has 5x114.3 PCD and a 64.1 mm center bore, and that lug threads are M12 x 1.5.
Enter the donor wheel and tire values into the on-page calculator. Use the calculator to compare diameters, offsets, and tire fitment on your vehicle.
Adjust custom wheel size in the calculator for rim diameter, width, and offset. Watch how offset changes track width and clearance.
Adjust custom tire size to match rolling diameter. The calculator updates tire diameter when you change rim diameter.
Verify hub-centric fit. If center bore is larger, plan a hub-centric ring sized to 64.1 mm hub and the wheel bore.
Confirm lug seat type and stud protrusion. Seat style and stud length are constraints not listed here, so measure directly or check OEM documentation.
Check tire clearance in the calculator for fender, suspension, and brake caliper interference. If the calculator flags rubbing, reduce width or increase offset as needed.
After simulation, validate physically before driving the car on public roads.
Problem: wheel does not center on hub. Cause: wheel bore larger than hub bore. Solution: use hub-centric rings sized to 64.1 mm hub and wheel bore.
Problem: lug nuts will not thread. Cause: thread pitch or seat mismatch. Solution: confirm M12 x 1.5 thread and correct seat type. Do not force incompatible nuts.
Problem: tire rubs on fender during full turn or compression. Cause: too wide a rim or too low an offset. Solution: increase offset or reduce rim width and re-test in the calculator.
Problem: TPMS warnings or sensor fitment issues. Cause: sensor type mismatch. Solution: check OEM sensor part numbers or fit new sensors that match the valve and protocol.
Problem: speedometer or ABS changes after changing tire diameter. Cause: different rolling circumference. Solution: adjust tire size back toward OEM diameter or recalibrate the vehicle if supported.
Use the on-page calculator to explore trade-offs between rim width, offset, and tire size before committing to wheels.
Where a spec is unknown or varies by trim, the recommended action is to measure directly or confirm with OEM documentation or dealer support.
Final checklist: correct PCD and thread, hub centricity, adequate caliper clearance, TPMS compatibility, and OEM torque values.

You can proceed with confidence now. If you need help interpreting calculator results, return with the donor wheel values and I will guide you.
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.
