OEM wheel and tire fitment specs for the 1998 Acura NSX, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
Recorded OEM specifications for the 1998 Acura NSX, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Center-bore records disagree: year-level hub 64.1 mm vs trim range 70.1–70.1 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 1998 Acura NSX. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 11 donor years. Listed 11 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
Center-bore records disagree (target year-level hub 64.1 mm vs trim range 70.1–70.1 mm). Unqualified overlap is not claimed until the conflict is resolved.

Recorded vehicle-side thread for the 1998 Acura NSX is M12x1.5. 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.
Donor width/offset sits outside the known OEM envelope for this vehicle. Recorded vehicle-side thread differs (M14x1.5 on the donor year vs M12x1.5 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.

Tire size

Provided OEM reference. Verify what is on your car.
Note: The NSX often uses staggered setups by model and market. This page only lists values provided. If your trim differs, confirm both axles using the on-page calculator and OEM sources before buying.
tl;dr
Use the calculator to compare donors against your NSX.
Match 5x114.3 and M12x1.5. Keep center bore 64.1 mm or larger with rings.
Start from 16x7 ET55, 215/45R16 as your baseline.
Make small offset and width changes, then check inner and outer clearance.
Do a test fit. Torque to OEM spec. Re-torque after 50–100 miles.
Recommendation
Work in a simple lifecycle: baseline, compare, simulate, test, then install.
1) Baseline your car
Confirm what is actually on the car now. Read tire sidewalls and wheel stamps.
If front and rear differ, record both. The provided values may be for one axle.
Check for spacers or aftermarket studs. Note any changes.
2) Use the calculator
Set Installed on to 1998 Acura NSX.
Enter Custom wheel size as 16x7 ET55. Enter tire 215/45R16.
For a donor, input that vehicle or a custom size you are considering.
Review inner clearance to the strut and outer poke to the fender.
Adjust width and offset in small steps. Watch both inner and outer changes.
If you change rim diameter, the tool updates tire diameter. Verify arch clearance lock-to-lock.
3) Fitment rules I follow on NSX
Keep bolt pattern exact at 5x114.3.
Offset close to ET55 unless the calculator shows safe clearance.
Center bore 64.1 mm hubcentric. Larger bores need proper rings.
Maintain tire overall diameter near OEM to protect handling and ABS behavior.
Check brake caliper spoke clearance. Profile varies by wheel design.
4) Hardware and seating
Use M12x1.5 hardware with correct seat type for the wheel.
If using aftermarket wheels with larger bores, use quality 64.1 mm rings.
Torque to the OEM spec from the service manual. Do not guess.
Impact
Offset changes affect scrub radius and steering feel.
Wider wheels can add grip but reduce inner clearance.
Larger diameter may alter effective gearing and speedometer reading.
Tire sidewall changes affect ride, turn-in, and braking feedback.
Unsprung weight changes will be felt in damping and response.
Risks
Inner rub on strut or liner from excessive backspacing.
Outer poke contacting fender on compression or full lock.
Brake caliper interference with tight-spoke designs.
Vibration from non-hubcentric mounting without rings.
Insufficient thread engagement if studs are short or washers used.
Load rating too low for vehicle weight and use.
TPMS compatibility if fitted. Some markets vary.

Checklist
Measure current front and rear wheel and tire sizes on the car.
In the calculator, set Installed on to 1998 Acura NSX.
Enter the provided baseline: 16x7 ET55 with 215/45R16.
Compare your target wheels. Confirm inner and outer clearances.
Confirm bolt pattern 5x114.3 and thread M12x1.5 on the new wheels.
Check center bore. If larger than 64.1 mm, add 64.1 mm rings.
Verify brake caliper clearance using the wheel’s spoke template if available.
Confirm torque spec from the OEM service manual.
Test fit one corner. Spin by hand. Check lock-to-lock.
Install all four. Torque in a star pattern. Re-torque after 50–100 miles.
If a specification on your car differs, verify with the door-jamb label and the Acura service manual. Then re-run the calculator for each axle. That keeps the result accurate to your build.
Gotchas
Some NSX trims and markets use staggered sizes. Confirm both axles.
Do not rely on tire size alone. Offset drives clearance outcomes.
Aftermarket wheel seat type can differ. Match conical vs ball seat.
Spacers change effective offset. Recalculate if spacers are used.
Keep changes controlled, verify with the calculator, and test fit. That process avoids surprises and protects the chassis feel Acura intended.
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.
