Use the on-page calculator to test custom wheel and tire combinations before buying.

If any value varies by trim, confirm with VIN or OEM dealer before purchase.

Step by step – How to use the calculator

Problem: you need to know whether a donor wheel or a custom wheel will fit your RDX without rubbing or safety issues.

1) Select "Installed on (your vehicle)" and confirm the page shows 2022 Acura RDX.

2) Choose the donor wheel or enter custom wheel size: rim diameter, rim width, and offset (ET).

3) Enter or adjust tire size: section width and aspect ratio. Note that changing rim diameter updates tire diameter automatically.

4) Compare listed bolt pattern, center bore, and thread size between donor and RDX. The calculator highlights mismatches.

5) Review clearance indicators for wheel-to-caliper and fender; look for recommended maximum offset change.

6) If the center bore is larger, add hub-centric ring thickness in the calculator to validate centering and load transfer.

7) Save or print the comparison for parts ordering and installer reference. For any unknown OEM option, verify with VIN and dealer parts department.

What each specification means (concise)

Bolt pattern (5x114.3): number of studs and pitch circle diameter. Must match or use proper adapter.

Center bore (64.1 mm): diameter hole at wheel center that centers on the hub. If larger, use hub rings; if smaller, wheel will not mount.

Thread size (M12 x 1.5): stud thread diameter and pitch. Lug nuts must match this specification.

Rim diameter and width (19x8.0): size of the wheel. Tire sizes are matched to this diameter and width range.

Offset (ET 50 mm): distance from wheel mounting face to wheel centerline. Affects track width and clearance.

Backspacing (5.97 in): distance from mounting face to inner wheel edge. Useful for measuring inner clearance limits.

Tire size (235/55R19): section width, aspect ratio, and rim diameter. Controls overall diameter and speedometer calibration.

Note: If a value varies by trim or optional equipment, confirm with VIN and OEM parts catalog. Use the on-page calculator for variation checks.

Validation

Problem: you need to be sure a candidate wheel will mount safely and clear suspension parts.

Validate bolt pattern and thread size first. They are binary fit checks for studs and lug nuts.

Validate center bore: wheel bore must be equal or larger than 64.1 mm. If larger, use a hub-centric ring sized to close the gap.

Validate offset/backspacing with the calculator. Small changes are acceptable; large shifts can cause rubbing or altered handling.

Validate tire diameter. A change over +/- 3% can affect speedometer, ABS, and ground clearance.

Document the comparison report from the on-page calculator before purchase or installation.

Troubleshooting – common mismatches and fixes

Bolt pattern mismatch

Problem: donor wheel bolt pattern differs from 5x114.3. Fix: do not force wheels. Use proper adapter or select wheels with the correct pattern. Adapters are a trade-off: they add length to studs and can change load paths. If using adapters, choose hub-centric, high-quality adapters rated for your vehicle load and torque to OEM specs.

Center bore is too large

Problem: wheel center bore larger than 64.1 mm causes off-centering. Fix: install hub-centric rings sized to the wheel bore and 64.1 mm hub. Validation: check that rings seat fully and eliminate radial runout.

Center bore is too small

Problem: wheel bore smaller than 64.1 mm will not fit. Fix: the wheel must be machined or rejected. Machining changes are permanent and should be done by a machine shop that confirms concentricity.

Thread size mismatch

Problem: lug nuts do not thread onto studs. Fix: stop and confirm thread pitch and diameter. Do not mix lug nut types. If using aftermarket wheels, confirm seat type (conical, ball) and choose matching lug nuts. Using incorrect nuts risks stripping studs.

Offset/backspacing issues

Problem: changed offset causing rubbing or poor handling. Fix: measure clearance at full lock and suspension compression. If rubbing occurs, options include reducing tire width, selecting a different offset, or trimming fender liners. Larger offset changes may require rolled fenders or suspension adjustments. Use the calculator to predict clearance before changes.

Common mistakes

Buying wheels with only rim diameter listed and assuming bolt pattern and center bore will match.

Using lug nuts with the wrong thread pitch or seat type without checking OEM specifications.

Ignoring backspacing and assuming offset alone tells the whole story. They are related but different measures.

Not using hub-centric rings when wheel bore is larger, which can produce vibration at highway speeds.

Using adapters without confirming stud length, torque specs, and load ratings.

Roadside & emergency advice

If you must change a wheel roadside, use the jack points in the owner’s manual. Secure vehicle on level ground before lifting.

Tighten lug nuts in a star pattern while vehicle is still raised, then torque to recommended spec after lowering. If torque spec is unknown, consult OEM sources or dealer.

Use the compact spare only for short distances and reduced speeds. Confirm spare size and speed limit printed on the spare or in the manual.

If a wheel exhibits vibration after installation, stop driving and re-check hub centering, lug torque, and possible damage to studs or wheel.

FAQ

Q: Can I use wheels from another Acura model?

A: Possibly, if they match 5x114.3 bolt pattern, 64.1 mm center bore, M12 x 1.5 threads, and acceptable offset. Use the calculator to compare exact dimensions. Confirm with VIN and parts catalogs for trim-specific notes.

Q: What if the catalog shows a slightly different offset?

A: Small offset changes are often acceptable but come with trade-offs: track width changes and potential rubbing. Use calculator validation and test fit when possible. When in doubt, stay closer to OEM offset.

Q: Are hub-centric rings required?

A: They are recommended when wheel bore is larger than hub bore. They restore proper centering and reduce the risk of vibration. They are unnecessary if wheel is already hub-centric to 64.1 mm.

Q: How do I confirm lug nut seat type?

A: Inspect an OEM lug nut or wheel seat surface. If uncertain, consult the dealer parts department or OEM service manual. The on-page calculator flags thread size, but seat type requires visual or OEM confirmation.

Q: Will a different tire size affect ABS or traction control?

A: Yes. Changing overall tire diameter beyond about +/- 3% can affect speedometer, ABS, and stability systems. Use the calculator to compute percent change in diameter and validate against OEM tolerances.
