2019-2025 Acura RDX Wheels: A Guide to Sizes, Trims, and Part Numbers
This guide details the critical differences in wheels across the Base, Technology, A-Spec, and Advance packages to ensure you get the right fit for your RDX.
- The single most important factor when buying a wheel is matching it to your RDX's specific trim package (Base, Technology, A-Spec, Advance), as sizes and designs are different.
- All 2019-2025 RDX trims use the same bolt pattern (5x114.3mm), center bore (64.1mm), and offset (+50mm), making swaps between trims physically possible if you use the correct tire size.
- There are no major recalls or TSBs for wheel defects; common issues like curb rash and bends are caused by road impacts.
- When buying used, prioritize wheels from reputable sellers who guarantee they are straight and free of cracks. A new OEM wheel can cost over $700, while a quality used one is often under $400.
Variant Guide: Matching the Right Wheel to Your RDX Trim
Choosing the correct wheel for your 2019-2025 Acura RDX is more complicated than just matching the diameter. Acura uses different wheel sizes, designs, and finishes for each trim level. Installing the wrong wheel can cause fitment issues or simply look incorrect. Always verify the style and finish of your existing wheels before purchasing a replacement.
Warning: The most common mistake is buying a wheel for the wrong trim package. For example, a 19-inch wheel from a Technology Package will not match the 20-inch wheels on an A-Spec model. Visually confirm your wheel design using the images and descriptions below.
| Trim Package | Years | Size | Style & Finish | Known OEM Part Numbers |
|---|---|---|---|---|
| Base | 2019-2025 | 19" x 8" | 5-Spoke, Pewter Gray or Berlina Black | 42700-TJB-A01, 42700-TJB-A61 |
| Technology | 2019-2025 | 19" x 8" | 5-Double Spoke, Machined Face with Dark Silver/Gray Pockets | 42700-TJB-A11, 08W19-TJB-200 |
| Advance | 2019-2021 | 19" x 8" | 10-Spoke (5 V-Spoke), Painted Shark Gray | 42700-TJB-A21 |
| Advance | 2022-2025 | 19" x 8" | Machine-Finished with Berlina Black Inserts | 42700-TJB-A61 |
| A-Spec | 2019-2025 | 20" x 8" | 5-Triple Spoke, Shark Gray / Dark Charcoal Painted | 42800-TJB-A00, 42800-TJB-A01, 20080A |
| A-Spec Advance | 2022-2025 | 20" x 8" | 15-Spoke, Shark Gray or Machine-Finished with Berlina Black | 42800-TJB-A20 |

Symptoms of a Damaged Wheel
A damaged wheel can compromise safety and vehicle performance. Look out for these common signs:
- Vibration or Shaking: A bent wheel will often cause a noticeable vibration in the steering wheel or through the seat, which typically gets worse with speed. A Reddit user with a CPO 2025 RDX reported a "whub whub whub" noise and vibration between 35-60 mph, which turned out to be a bad wheel bearing caused by a pothole impact that also damaged the wheel.
- Constant Air Loss: If a tire continually loses air pressure without any visible puncture, the wheel may have a hairline crack. These cracks often form on the inner barrel of the wheel where they are not easily visible.
- Visible Damage: Obvious signs include cracks, significant bends (especially on the lip or flange), and heavy curb rash. While minor cosmetic scuffs are common, deep gouges can indicate a more serious impact that may have compromised the wheel's structure.
- Poor Tire Bead Seal: A bent or corroded wheel lip can prevent the tire from sealing properly, leading to slow, persistent leaks.
Known Issues, Recalls, and Service Bulletins
As of early 2026, there are no specific NHTSA recalls or Technical Service Bulletins (TSBs) for wheel cracking, finish peeling, or structural failure on the 2019-2025 Acura RDX. Most wheel-related problems are due to external factors like hitting potholes or scraping against curbs. Some owners on forums have noted that the painted finishes, particularly on the A-Spec wheels, can be susceptible to chipping or scratching from curb impacts.
Buying a Used 2019-2025 RDX Wheel
A used OEM wheel is an excellent, cost-effective alternative to a new dealer part, but careful inspection is key. Here’s what to look for:
- Check for Cracks: Inspect the entire wheel, front and back, paying close attention to the area where the spokes meet the outer rim and around the lug nut holes. Use a bright light to look for hairline fractures.
- Look for Bends: Minor bends can be hard to see with the naked eye. The best way to check is to have the wheel spun on a wheel balancer. A reputable seller of used wheels will have already done this. Ask the seller if the wheel has been tested and is guaranteed to be straight.
- Inspect for Previous Repairs: Look for signs of welding on the back side of the wheel. While a professional weld can be safe, it's a sign of a previous major repair. Also, check for excessive paint or filler, which might hide underlying damage.
- Assess the Finish: Check for peeling clear coat, deep scratches, or heavy curb rash. Minor cosmetic damage can often be repaired, but extensive finish failure may require the wheel to be completely refinished.
- Why OEM is Often Better: Original Equipment Manufacturer (OEM) wheels are designed specifically for the RDX's weight, handling, and suspension. Many cheaper aftermarket wheels are heavier and made from lower-quality materials, which can lead to easier bending or cracking and may negatively affect ride quality and fuel economy.
Pro Tip: When buying a used wheel, always ask the seller to confirm the part number and the trim level it came from. This is the best way to ensure you get an exact match for your RDX.
Wheel Refinishing and Repair
If your wheel has cosmetic damage like curb rash or peeling paint, refinishing is a viable option. A professional wheel repair shop can strip, repair, and repaint or powder-coat the wheel to look like new. The cost for this service typically ranges from $100 to $250 per wheel, depending on the extent of the damage and the complexity of the finish. One forum user reported paying $125 for a mobile service to repair curb rash on an A-Spec wheel with a perfect color match.
Cost Comparison
| Part Type | Estimated Cost (Per Wheel) | Notes |
|---|---|---|
| New OEM | $500 - $770 | Highest cost, but a guaranteed perfect match and new condition. |
| Used OEM | $225 - $400 | Great value. Inspect carefully for damage before buying. |
| Remanufactured OEM | $250 - $400 | A used OEM wheel that has been professionally repaired and refinished to a like-new appearance. |
| New Aftermarket | $150 - $500+ | Quality and weight can vary significantly. May not be as durable as OEM. |
| Wheel Refinishing (Existing Wheel) | $100 - $250 | Cost-effective way to fix cosmetic damage on your current wheel. |
Frequently Asked Questions (FAQ)
What happens if I use a wheel with the wrong offset?
Using a wheel with an incorrect offset can cause serious problems. Too little offset (more negative) pushes the wheel outward, which can cause the tire to rub on the fender. It also increases stress on wheel bearings and suspension components, leading to premature wear. Too much offset (more positive) pulls the wheel inward, risking interference with brake calipers and suspension parts. The 2019-2025 RDX uses a +50mm offset for its factory wheels.
Can I put A-Spec 20-inch wheels on my Base model RDX?
Yes, this is a common upgrade. The 20-inch A-Spec wheels share the same bolt pattern, center bore, and offset as the 19-inch wheels. However, you will also need to purchase the correct tires (255/45R20) to maintain the proper overall diameter and avoid speedometer errors.
Do I need new TPMS sensors for a replacement wheel?
If you are swapping your tire onto a replacement wheel, you can reuse your existing Tire Pressure Monitoring System (TPMS) sensor. However, if you are building a new set of wheels (e.g., for winter tires), you will need to buy a new set of TPMS sensors compatible with the 2019+ RDX. Sensors from the previous RDX generation will not work as they operate on a different frequency.
Where is the paint code for my wheels?
Unlike body paint, wheels do not have a specific, easily accessible paint code listed on the vehicle. The color name (e.g., 'Shark Gray', 'Berlina Black') is part of the wheel's part description. If you need to touch up a scratch, your best options are to either buy a pre-matched touch-up paint from a specialty supplier or have a professional wheel shop custom-mix the color.
