Recorded vehicle-side thread for the 1994 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.

Goal
You need safe, streetable replacement wheels and tires for a 1994 Acura NSX without causing rubbing, braking interference, or hub stress. The immediate problem is that several critical fitment items are unknown. I will show how to confirm them, use the on-page calculator, and validate a candidate wheel/tire set so you can install with confidence.
Prerequisites
Known OEM wheel/tire values you already have: 15 x 6.5 rim, ET 55 mm, backspacing 5.42 in, tire 205/50R15. These are the baseline reference.
A way to measure or confirm the remaining unknowns: bolt pattern, center bore (mm), and lug thread size. These values are not provided here and must be confirmed.
Access to the on-page wheel/tire calculator on this page. Use it to compare donor wheels versus installed wheels and to model custom sizes.
Basic tools: caliper, lug wrench, torque wrench, jack and stands. Consider wheel centering rings if hubs are non-centric.
Recommendation: if you need a torque wrench or centering rings, consider these search tools: torque wrench and hub centric rings.
Step by step
1. Define the problem in measurable terms
We know rim diameter, width, offset, backspacing and OEM tire size. The constraints left are bolt pattern, center bore, and lug thread. Without them you cannot safely mount wheels.
2. Confirm bolt pattern
Do not guess. Use one of these methods to confirm the bolt pattern precisely.
Check the factory service manual, part fiche, or the dealer parts department for the 1994 NSX bolt pattern.
Remove a wheel and measure physically. For a reliable result use a bolt pattern gauge or a caliper and photograph for reference.
If you cannot measure, obtain OEM wheel part numbers from a reputable parts catalog and cross-reference their bolt pattern.
3. Confirm center bore and thread size
Measure the hub bore with a caliper or use OEM specs. For lug thread size, use a thread pitch gauge or have a tire shop confirm the stud/thread specification. These are critical for hub centering and lug security.
4. Use the on-page calculator
Open the calculator on this page. Use these steps inside the tool.
Set “Installed on (your vehicle)” to the known OEM values: 15 x 6.5, offset 55 mm, tire 205/50R15.
If testing a candidate wheel, set “Wheels from (donor vehicle)” or use “Custom wheel size” to enter rim diameter, width, and offset.
Adjust “Custom tire size” if you plan a different tire width or aspect ratio. Remember changing rim diameter updates the tire diameter in the comparison.
Read the calculator outputs for overall diameter, sidewall change, and virtual scrubbing diameter. Use those numbers to assess speedometer error and clearance trade-off.
5. Evaluate clearances and trade-offs
Focus on two clearance zones: brake/caliper clearance and fender/inner-lip clearance. Lower offset moves the wheel outward increasing track and potential fender rub. Higher offset moves the wheel inward risking brake or suspension interference. Use the calculator to quantify how many millimeters a candidate wheel will move relative to OEM.
6. Physical test fit
Before final installation, do a dry fit on the hub. Check for bead seating, hub centering, and that lugs engage freely. Confirm clearance with full steering lock and suspension compression. If the center bore is larger than the hub, use appropriately sized centering rings.
7. Final installation and torque
Torque lug nuts to the OEM-specified torque using a calibrated torque wrench. I recommend re-torquing after 50 to 100 miles, but confirm OEM guidance for your vehicle.
Validation
Validate fitment using these checks before you consider the job complete.
Check
How to validate
Bolt pattern match
Wheel seats flush and lugs thread fully without cross-threading.
Centering
Wheel sits concentric on hub; use centering rings when hub bore is smaller than wheel bore.
Brake and suspension clearance
No contact with caliper, rotor, control arms at full lock and compressed suspension.
Fender clearance
No rubbing at static ride height and during suspension travel; test with weight in car if possible.
Tire diameter and speedo
Calculator diameter output within acceptable range or note correction needed for speedometer.
Lug torque and re-torque
Torque to OEM spec and re-check after 50–100 miles per manufacturer guidance.
Troubleshooting
Wheel does not center or has runout
Cause: mismatched center bore or debris on hub. Solution: clean the hub face, use matching centering rings, and re-check runout with a dial indicator.
Rubbing on fender or inner liner
Cause: offset change or wider tire than tire/guard allows. Options: reduce tire width, increase offset toward OEM, roll or modify the fender lip, or fit a spacer with caution. Evaluate the trade-off between track width and suspension geometry.
Contact with brake caliper or suspension
Cause: wheel inner face hitting caliper or control arm. Solution: select a wheel with more positive offset or different spoke/backspacing. Do not use shims that create unsafe loads on studs.
Vibration or wobble after installation
Cause: unbalanced wheel/tire, loose lug nuts, or hub runout. Solution: re-balance tires, torque lugs correctly to OEM spec, and inspect hub for damage.
TPMS or valve stem issues
Cause: aftermarket wheels incompatible with sensors. Solution: confirm TPMS sensor fitment or swap sensors to the new wheels.
Wrap up
Summary: you have a clear path. Confirm the bolt pattern, center bore, and lug thread before ordering wheels. Use the on-page calculator to model changes and quantify trade-offs. Physically test fit, validate clearances, and follow OEM torque guidance. Doing these steps reduces risk and delivers a safe, reliable result.
If you need help measuring any unknown value or want me to review specific candidate wheel sizes, provide the bolt pattern, center bore, thread size, and the candidate wheel dimensions. I will walk through the calculator outputs with you and recommend next steps.
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.
