2009 Honda Ridgeline Wheel Interchange and Fitment Guide
Use this guide and the on-page wheel interchange calculator to compare donor wheels with your 2009 Honda Ridgeline. The specifications below are the known values provided for this vehicle, but equipment can vary by trim, market, replacement wheel, and model configuration. Confirm critical dimensions with the vehicle owner’s manual, a Honda parts source, the wheel markings, or a qualified technician before purchase or installation.
Known OEM Fitment For 2009 Honda Ridgeline
The following specifications are the available OEM fitment data for the 2009 Honda Ridgeline:
| Specification |
Known value |
| Bolt pattern, studs x PCD |
5x120 |
| Center bore |
64.1 mm |
| Thread size |
M14 x 1.5 |

| Tire rim diameter listed in the supplied data |
R17 |
Important data check: The supplied information lists an 18-inch rim diameter and an R17 tire rim diameter. A tire marked R17 is designed for a 17-inch wheel, not an 18-inch wheel. Do not combine these values as one confirmed wheel and tire package. Verify the correct wheel diameter and tire size for your specific Ridgeline using the tire sidewall, door-jamb label, owner’s manual, and Honda or tire manufacturer fitment information.
A wheel with the correct 5x120 bolt pattern may still be unsafe or unusable if its center bore, offset, width, brake clearance, load rating, or fastener seat is unsuitable. The listed values should be treated as a starting point for verification, not a guarantee that every 5x120 wheel fits.
How To Use The Wheel Interchange Calculator
The calculator lets you compare wheels from a donor vehicle with the wheels installed on your 2009 Honda Ridgeline. Use it to review dimensional differences before you buy, but do not use calculator results as a substitute for physical clearance checks or OEM confirmation.
- Select the donor vehicle under “Wheels from” and select the 2009 Honda Ridgeline under “Installed on.”
- Review the donor wheel diameter, width, offset, bolt pattern, and center bore when available.
- Compare the donor dimensions with the installed vehicle values. Pay particular attention to offset, width, and center bore.
- Use “Custom wheel size” when you are evaluating an aftermarket or used wheel. Enter the actual rim diameter, width, and offset printed on the wheel or provided by the manufacturer.
- Use “Custom tire size” to enter the proposed tire section width and aspect ratio. Confirm that the tire’s rim diameter matches the selected wheel diameter.
- Review the change in tire diameter, sidewall height, and overall rolling size. Changing rim diameter updates the tire diameter in the comparison.
- Record any clearance difference shown by the calculator, then verify the result on the vehicle with a physical test fit or professional inspection.
If a specification is blank, uncertain, or different between sources, do not guess. Check the wheel casting or stamp, the tire sidewall, the vehicle label, and current OEM or manufacturer documentation.
Fitment Checklist Before You Buy
- Confirm the vehicle is a 2009 Honda Ridgeline and identify its trim and market.
- Confirm the wheel uses a 5x120 bolt pattern.
- Confirm the center bore is compatible with the vehicle hub. A wheel with a larger bore may require properly sized hub-centric rings, while a smaller bore generally will not fit over the hub.
- Compare wheel offset and width with the known ET45 and 7.5-inch reference values. A change can affect suspension, fender, steering, and brake clearance.
- Verify that the wheel’s load rating is sufficient for the Ridgeline and its intended cargo or towing use.
- Check brake caliper and suspension clearance. Spoke shape can cause interference even when diameter, width, and offset appear suitable.
- Confirm the wheel’s lug-seat type matches the required fasteners. Do not assume that a compatible thread size means the lug seat is correct.
- Inspect used wheels for cracks, bends, corrosion around the bead, damaged mounting holes, and repaired areas.
- Verify tire size, speed rating, load index, rim diameter, and inflation requirements. The supplied R17 tire value must be reconciled with the supplied 18-inch rim value before ordering.
- Check that the tire does not contact the strut, control arm, inner fender, bodywork, or suspension through the full steering and suspension range.
Plus Sizing And Common Upgrades
Plus sizing changes the wheel diameter while attempting to preserve a similar overall tire diameter by using a different tire aspect ratio. It can change ride comfort, steering response, wheel protection, speedometer behavior, ground clearance, and the risk of impact damage.
No specific plus-size combination is confirmed here because the supplied data contains a conflict between an 18-inch rim diameter and an R17 tire rim diameter. Use the calculator to compare candidate wheel and tire sizes, then confirm the complete combination with a tire manufacturer, Honda documentation, and a physical clearance check.
Common wheel upgrades may include a different diameter, width, or offset, but each change requires separate verification. A wider wheel or lower offset can move the tire closer to the fender, while a higher offset can reduce inner clearance. A larger wheel does not automatically provide adequate brake clearance, and a different center bore does not automatically make a wheel hub-compatible.
Do not select a tire solely by matching section width. The tire must match the wheel diameter, have a suitable approved rim-width range, meet the vehicle’s load and speed requirements, and maintain safe clearance at normal and loaded ride height.
Installation Tips
- Clean the hub face and wheel mounting surface before installation. Remove rust, dirt, and loose coatings without damaging the mating surfaces.
- Hand-start every fastener to prevent cross-threading. Never force a lug nut or wheel bolt with an impact tool.
- Use only the correct M14 x 1.5 fasteners when confirmed for the vehicle, together with the correct seat style and length.
- Snug the fasteners in a star or crisscross pattern, then torque them with a calibrated torque wrench to the vehicle or wheel manufacturer’s specified value.
- Do not apply anti-seize to wheel studs or lug threads unless the manufacturer specifically requires it, because lubrication can change clamping force.
- Check that the wheel sits fully flush against the hub and that no casting, spacer, or fastener component prevents proper seating.
- After installation, rotate each wheel by hand and inspect for contact. Turn the steering from lock to lock where appropriate, and check clearance again with the vehicle loaded as recommended by the manufacturer.
- Recheck fastener torque after the first short drive and follow the wheel manufacturer’s maintenance instructions.
- Stop immediately if there is vibration, rubbing, steering pull, loss of tire pressure, or unusual noise. Have the installation inspected before continuing to drive.
Tools And Helpful Supplies
Basic measuring and installation tools can help confirm fitment, but they cannot replace OEM specifications or a professional inspection when clearance is uncertain.
- Calibrated torque wrench for final fastener tightening. View torque wrench options on Amazon.
- Socket and breaker bar that fit the confirmed wheel fasteners.
- Steel ruler, calipers, or an offset and backspacing measuring tool.
- Tire pressure gauge and an accurate inflation source.
- Wheel chocks and a properly rated floor jack.
- Jack stands rated for the vehicle.
- Wire brush or approved hub-cleaning brush.
- Thread and lug-seat identification references when the replacement wheel’s fasteners are uncertain.
Support the vehicle with jack stands on approved lifting points. Never work under a vehicle supported only by a jack.
FAQs
Does the 2009 Honda Ridgeline use a 5x120 bolt pattern?
The supplied OEM fitment data lists a 5x120 pattern. Confirm the pattern on the exact vehicle and replacement wheel before purchase.
What is the center bore listed for this Ridgeline?
The supplied value is 64.1 mm. A replacement wheel must have a compatible hub fit, and a larger center bore may require correctly sized hub-centric rings.
What thread size is listed?
The supplied thread size is M14 x 1.5. Thread size alone does not identify the correct lug-seat shape, fastener length, or final torque specification.
Is the original wheel diameter 17 or 18 inches?
The supplied data lists an 18-inch rim diameter but also lists an R17 tire rim diameter. These values conflict because an R17 tire fits a 17-inch wheel. Verify the correct wheel and tire information from the vehicle label, tire sidewall, owner’s manual, and OEM sources before ordering.
Can any 5x120 wheel fit this Ridgeline?
No. Bolt pattern is only one requirement. Center bore, offset, width, brake clearance, load rating, lug-seat type, and tire compatibility must also be correct.
How can I compare a donor vehicle’s wheels?
Select the donor under “Wheels from” and the 2009 Honda Ridgeline under “Installed on.” Compare diameter, width, offset, center bore, bolt pattern, and tire dimensions. Use custom fields when the donor or aftermarket specifications are not listed.
Does changing the wheel diameter change the tire diameter?
The calculator updates tire diameter when the rim diameter changes. You must still enter a tire size with the same rim diameter as the wheel and confirm the resulting size with the tire manufacturer.
Are wheel spacers required for a different offset?
Do not assume spacers are required or safe. Spacers alter wheel position, may require different fasteners, and can affect hub engagement and bearing loads. Use them only when approved for the application and installed according to the manufacturer’s instructions.
What should I do if the calculator shows a possible fit?
Treat the result as a screening comparison. Confirm wheel load rating, lug compatibility, hub fit, brake and suspension clearance, tire specifications, and fender clearance through OEM documentation and a physical inspection before driving.
