2017 Acura RDX Wheel Interchange

2017 Acura RDX wheel fitment guide

You want wheels that bolt up, clear the brakes, and drive vibration free. The confusion starts with offset, hub bore, and tire diameter changes. This page walks you from uncertainty to a confident fit using the on‑page calculator and the known OEM specs for the 2017 Acura RDX.

1. Goal

Select and validate wheels and tires that safely fit a 2017 Acura RDX under real‑world constraints. You will compare donor wheels in the calculator, check clearance and speedometer impact, and plan hardware like hub rings and lug nuts.

2. Prerequisites

Start with the factory baseline. These are the known OEM specs for the 2017 Acura RDX:

Have these on hand:

• The donor wheel size and offset, and tire size you intend to run. If unknown, measure or request from the seller.
• Access to the wheelinterchange.com calculator on this page.
• Basic tools: a torque wrench, a way to lift the vehicle safely, and a way to measure clearances.

Helpful tools and parts:

• 1/2 inch torque wrench
• 64.1 mm hub centric rings
• M12x1.5 lug nuts

Assumption to validate: torque spec and TPMS details can vary by trim and market. Confirm both with the owner’s manual or OEM service information before final install.

3. Step by step

3.1 Set your baseline in the calculator

• Installed on (your vehicle): select 2017 Acura RDX.
• Confirm baseline wheel 18 x 7.5 ET45 and tire 235/60R18 are loaded. These anchor all comparisons.

3.2 Add the donor wheel and tire

• Wheels from (donor vehicle): select the vehicle you are sourcing from, or enter the wheel size manually using Custom wheel size.
• If you plan a different tire, set Custom tire size. The calculator will update overall diameter and speedometer change.

3.3 Read the results with clear acceptance checks

• Inner clearance to suspension and brakes: keep at least 3 to 5 mm more than zero after accounting for tire bulge. This reduces rub risk under load.
• Outer poke vs fender: aim to stay within the fender line. A few millimeters of extra poke can be fine, but too much increases splash, rub, and bearing load.
• Offset trade‑off: more positive offset pulls the wheel inward for caliper clearance, more negative pushes it outward for strut clearance. Use the calculator’s inner and outer change readouts to balance these constraints.
• Tire diameter change: a common recommendation is within about 2 to 3 percent of OEM diameter. This keeps speedometer error and gearing changes modest.

3.4 Match the hub and hardware

• Center bore: vehicle hub is 64.1 mm. If the donor wheel bore is larger, plan hub centric rings to 64.1 mm. If smaller, the wheel will not seat on the hub.
• Lug thread: M12 x 1.5. Match lug nut thread and seat style to the wheel design. Many aftermarket wheels use conical seats, while some OEM wheels use ball seats. Verify the seat type by manufacturer guidance.

3.5 Physical test fit

• Install the wheel by hand and snug in a star pattern. Spin the wheel to check static caliper clearance.
• Lower the car, turn to full lock both directions. Listen and look for liner or arm contact.
• Load test: with a helper, compress the suspension and inspect the closest points. Use clay, putty, or tape to measure minimum gaps.

3.6 Final install checks

• Torque the lugs in stages to the value in your Acura service data. Re‑torque after 50 to 100 miles.
• If using spacers, only use hub‑centric spacers that keep a 64.1 mm hub interface and confirm stud engagement length. This adds complexity and must be measured carefully.
• Sync or relearn TPMS as required by your trim. Procedures vary, so confirm with OEM instructions.

4. Validation

• Calculator validation: recheck inner clearance and poke with the exact tire you will mount, not only wheel width. Tire section width and shoulder shape affect real clearance.
• Speedometer check: use a GPS app at a steady 60 mph and compare to cluster. Deviations should match the calculator’s estimate.
• Road test: drive 10 to 15 miles including turns, bumps, and freeway speeds. Confirm no rub, no vibration, and no TPMS warning.
• Visual inspection: after the test, look for witness marks on liners, arms, or calipers. Any mark is a fail and needs adjustment.

5. Troubleshooting

Vibration at 55 to 75 mph

• Likely causes: missing hub rings on larger‑bore wheels, wheel imbalance, or bent wheel. Add 64.1 mm rings when the wheel bore is larger than 64.1, then road force balance.

Immediate caliper contact

• Offset too low or spoke design too flat. Use the calculator to model a higher positive offset or a wheel with better caliper clearance data. Spacers can solve inner barrel contact, but require hub‑centric design and longer studs. Validate thoroughly.

Fender or liner rub on bumps or full lock

• Too much outer poke or tire diameter too large. Reduce width, increase positive offset, or choose a tire with a slightly smaller section width or aspect ratio. Keep diameter change within the recommended band.

TPMS light on

• Reinstall the OEM sensors in the new wheels or use compatible programmable sensors. Confirm frequency and relearn process using OEM sources for your VIN.

Uneven steering feel after install

• Check tire pressures, then get an alignment. Large offset changes can alter scrub radius and steering effort. Use the calculator to minimize this trade‑off.

6. Wrap up

With the 2017 Acura RDX baseline loaded in the wheelinterchange.com calculator, you can compare any donor wheel against your car in minutes. Keep the 5x114.3 bolt pattern, 64.1 mm hub centering, M12x1.5 threads, and the OEM geometry in mind. Validate clearance, tire diameter, and hardware before you commit. If a value is unknown for your trim, confirm it using the calculator and OEM service data. This approach turns guesswork into a clear, repeatable process.
