2001 Acura NSX Wheel Interchange
OEM wheel/tire sizes and fitment specs for the 2001 Acura NSX.
tl;dr
2001 Acura NSX known OEM wheel data below. NSX often runs staggered sizing by axle. If your rear specs differ, confirm with the on-page calculator and your OEM service info.
| Spec | Value |
|---|---|
| Bolt pattern | 5x114.3 |
| Center bore | 64.1 mm |
| Thread size | M12 x 1.5 |
| Rim diameter | 16 in |
| Rim width | 7.0 in |
| Offset (ET) | 55 mm |
| Backspacing | 5.67 in |
| OEM tire size | 215/45R16 |
Do not assume this covers both axles. The NSX commonly uses different rear sizing. Verify by VIN or owner’s manual.
Recommendation
I treat the 2001 NSX as a precision chassis. Start with OEM geometry, then change one variable at a time.
- Confirm both axles. If your rear wheel differs, record its diameter, width, and offset.
- Stay hub-centric to 64.1 mm. Avoid large center bore without proper rings.
- Match bolt pattern 5x114.3 and M12x1.5 threads only.
- Use the calculator. Compare donor wheels against your NSX. Adjust width and offset until inner and outer clearances look safe.
- Keep tire overall diameter close to OEM. The calculator updates diameter as you change rim size.
- If upsizing, test a small step first. Example workflow: 16x7 ET55 to a 17x7.5 with a near OEM effective offset. Confirm inner clearance and fender poke in the tool.
- Select tires after wheels. Enter section width and aspect ratio to maintain diameter and speedometer behavior.
Impact
- Offset changes alter scrub radius and steering feel. Small moves are noticeable on the NSX.
- More width pushes inboard or outboard. Inner side risks strut and liner. Outer side risks fender contact.
- Larger diameter tightens brake and arch clearance. The calculator shows diameter change as you adjust sizes.
- Unsprung mass affects ride and braking. Lightweight, properly rated wheels help preserve handling.
- Hub fit controls vibration. 64.1 mm hub-centric fit is preferred.
Risks
- Staggered reality. Many NSX trims use larger rear wheels and tires. Do not copy front sizing to the rear without checks.
- Caliper clearance. Spoke design can hit the caliper even if width and offset look OK in numbers.
- Hub bore mismatch. Oversized bores need quality hub-centric rings sized to 64.1 mm.
- Thread engagement. Lug nuts must fully seat with proper engagement. Never force cross-threaded nuts.
- Spacer use. Only if necessary, with hub-centric spacers and extended studs. Re-validate offset and load path.
- Tire load and speed ratings. Match or exceed OEM ratings for safety.
- ABS and TCS behavior. Large tire diameter changes can upset calibration.
- Unknown trim differences. If values vary by axle or package, confirm via OEM sources.
Next actions
Checklist
- Identify both axle specs on your car. Check the owner’s manual or dealer printout by VIN.
- Open the calculator on wheelinterchange.com. Set “Installed on” to 2001 Acura NSX.
- Enter your current wheel and tire sizes for both axles.
- Test a candidate wheel in “Wheels from” or “Custom wheel size”. Adjust width and offset until clearances are safe.
- Dial tire size in “Custom tire size”. Keep overall diameter near OEM per the tool readout.
- Confirm hub bore 64.1 mm and bolt pattern 5x114.3 on the donor wheel.
- Buy quality hardware that matches M12x1.5 threads and correct seat type. If unknown, verify with the wheel manufacturer.
- Install with clean hubs and proper torque to the OEM spec listed in your service manual. Recheck torque after a short shakedown drive.
- Road test at low speed. Listen and feel for vibration or rubbing. Inspect inner liners and caliper clearance immediately.
Gotchas
- Same numbers, different results. Spoke shape can make or break caliper clearance.
- Backspacing matters. The given 5.67 in guides inner clearance. Recalculate if you change width or offset.
- Center caps and ring depth. Some rings or caps interfere with grease caps. Test-fit before tire mounting.
Helpful tools
If any spec is unknown or differs by trim, use the on-page comparison and confirm against OEM service data. That protects fitment and safety.
