Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2020 Acura MDX. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 34 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
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.
Donor width/offset sits outside the known OEM envelope for this vehicle. Precomputed data suggested a spacer; geometry was re-checked against OEM envelope.

tl;dr
The 2020 Acura MDX runs 5x120, 64.1 mm center bore, and M14 x 1.5 studs. OEM wheels are 20x8 ET55 with 6.17 in backspacing. Factory tire size is 245/50R20. Use the on-page calculator to compare donor wheels and custom sizes. Keep inner and outer clearances close to stock, and keep overall tire diameter near OEM. Use hub-centric rings if the wheel bore is larger than 64.1 mm. Confirm brake clearance before downsizing. Torque to the value in your owner’s manual.
Recommendation
Start from the OEM baseline, then adjust in small steps. Match hub fit and stud size first. Then tune width, offset, and tire size with the calculator.

Use the calculator like a tech
Set Installed on to 2020 Acura MDX. Confirm the OEM line above.
Enter a donor wheel or pick Custom wheel size. Change width and offset slowly.
Watch inner clearance to the strut and control arms. Keep it close to OEM.
Watch outer poke vs the fender lip and liners. Avoid large increases.
Set Custom tire size to keep overall diameter near stock. The tool recalculates tire diameter as you change rim diameter.
If the new wheel center bore is larger than 64.1 mm, plan hub-centric rings to 64.1 mm ID.
Hardware and fit checks
Confirm the lug seat type matches your wheels. Do not mix seat styles.
Use the torque spec from the Acura owner’s manual. Re-torque after a short drive.
If downsizing rim diameter, test fit for brake caliper clearance before mounting tires.
Impact
Each change affects clearance, handling, and wear. Plan for balanced tradeoffs.
Offset and width shift scrub radius and bearing load. Closer to OEM feels most stock.
More outer poke can improve stance but risks fender rub under compression.
More inner push can contact struts, sway links, or liners on steering lock.
Tire diameter changes affect speedometer and ABS logic. Keep close to OEM.
Heavier assemblies increase unsprung mass and stopping distance.
Non hub-centric fit can cause vibration at highway speeds.
Risks
Caliper or knuckle contact if inner clearance shrinks too much.
Fender-liner rub from extra poke or taller tires.
Vibration from wheels that are not centered on the 64.1 mm hub.
Damaged studs from incorrect lug seat or thread pitch. The MDX uses M14 x 1.5.
AWD stress from large tire diameter mismatch. Keep left to right and front to rear very close.
TPMS issues if sensors are not transferred or relearned.

Checklist
Baseline: note 5x120, 64.1 mm bore, M14 x 1.5, 20x8 ET55, 245/50R20.
Calculator: compare your donor wheels to OEM. Aim for similar inner and outer clearance.
Tires: choose a size that keeps overall diameter near OEM. A small change is usually best.
Hardware: match lug seat style. Add hub-centric rings if bore is larger than 64.1 mm.
Test fit: mount a bare wheel. Spin and steer lock to lock. Check all clearances.
Install: use a torque wrench and follow a star pattern. Re-torque after 50 to 100 miles.
If any value is unclear or varies by trim, confirm with the on-page calculator and your OEM service information. This approach keeps the 2020 MDX safe and predictable.
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.
