Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2019 Acura NSX. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 9 donor years. Listed 9 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.

2019 Acura NSX wheel fitment guide
You’re looking for fast, safe answers on the 2019 Acura NSX. Below is the OEM baseline we have, how to use the on-page calculator to compare options, and the critical checks before you buy or bolt up.

Note: The NSX commonly runs a staggered setup. The data above may reflect only one axle. If your trim differs, confirm each axle’s factory spec in the owner’s manual, door placard, or OEM parts catalog, and validate with the calculator on wheelinterchange.com.
tl;dr
Baseline: 5x120, 70.1 mm bore, M14x1.5, 19x8.5 ET55, 245/35R19.
Treat this as the reference when comparing donor wheels in the calculator.
Match bolt pattern and center bore. Keep inner and outer clearances safe.
Staggered is likely. Verify front vs rear before ordering.
Torque fasteners to OEM spec and re-check after 50–100 miles.
Recommendation
Work from the OEM geometry first. Use the calculator to compare any donor wheel or custom size against 19x8.5 ET55 with a 245/35R19 tire. Keep overall tire diameter close to stock, and watch inner clearance to suspension and brakes as you change width or offset.
If a donor wheel shares 5x120 and clears the 70.1 mm hub, you’re halfway there. If the wheel’s center bore is larger, plan hub-centric rings to 70.1 mm. If it’s smaller, it will not fit without machining.
Offset changes: a smaller ET pushes the wheel outward, a larger ET moves it inward. Use the calculator to see inner and outer clearance changes in millimeters.
Tire changes: adjusting rim diameter updates overall tire diameter in the tool. Aim for a small variance so ABS, traction control, and speedometer behavior stay predictable.
Seat type and nuts: match the lug seat to the wheel design and use M14x1.5 hardware. Do not mix ball and cone seats.
Impact
Handling: wider wheels can add grip but may tramline. Offset shifts can alter steering feel and scrub radius.
Clearance: inner barrel vs calipers and knuckle is the first constraint. Outer lip vs fender is the second. The calculator highlights both.
Speedometer: diameter changes adjust indicated speed. The tool shows the percentage difference for quick judgment.
Tire wear: mismatched diameters front to rear can stress AWD systems. Keep axle-to-axle diameter relationships consistent with OEM.
Ride and NVH: larger diameters with shorter sidewalls ride firmer and transmit more noise.
Risks and gotchas
Partial data: the NSX often uses different front and rear sizes. Confirm both axles with OEM sources if you plan a full set.
Centering: driving on lug-centric fit can cause vibration. Use hub-centric rings if the wheel bore is larger than 70.1 mm.
Brake clearance: spoke design matters as much as barrel diameter. Test for caliper-to-spoke clearance, not just inner barrel.
Lug engagement: ensure full thread engagement with M14x1.5 hardware, especially if using spacers. Avoid thin shank or mismatched seat nuts.
Load rating: wheel and tire load ratings must meet or exceed OEM. Do not assume aftermarket ratings are sufficient.
TPMS: plan compatible sensors and relearn procedure for 2019 Acura systems.
Next actions
Checklist
Identify if your 2019 NSX has staggered OEM sizes. Check door placard and manual.
Open the wheelinterchange.com calculator. Set “Installed on” to 2019 Acura NSX. Enter the baseline above.
Enter the donor wheel or your custom size. Adjust width and offset to visualize inner and outer clearance changes.
Set tire size. Verify overall diameter and speed error presented by the tool. Keep differences small and balanced front to rear.
Confirm bolt pattern 5x120, center bore 70.1 mm, and M14x1.5 hardware compatibility.
Plan hub-centric rings if the wheel bore is larger than 70.1 mm.
Before final mounting, test-fit one corner. Spin-check for caliper and suspension clearance with the car on stands.
Install with correct seat-type lugs. Torque to OEM spec. Re-torque after 50–100 miles.
You now have the baseline and a process. Use the calculator to validate geometry, then confirm hardware and clearances. That keeps your 2019 Acura NSX safe and dialed-in.
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.
