2014-2016 Acura RLX Wheel Guide: Vibrations, Bends, and Noise-Reducing Tech
This guide covers the unique noise-reducing wheels on the 2014-2016 Acura RLX, including common failure symptoms, how to inspect a used wheel, and crucial technical specifications.
- The standard 2014-2016 RLX wheel is 18x8 with a 5x120mm bolt pattern and a +50mm offset.
- These wheels feature a unique noise-reducing resonator; cheap aftermarket wheels will not have this feature.
- When buying used, inspect carefully for cracks, bends, and signs of previous welded repairs.
- Vibrations are the most common symptom of a damaged wheel, but noises from the P-AWS system can sometimes be confused for a wheel issue.
Known Issues, Recalls, and TSBs
While the 2014-2016 Acura RLX wheels themselves have not been the subject of a direct safety recall, the vehicle has several related bulletins and recalls that owners should be aware of. Problems with the Precision All-Wheel Steer (P-AWS) system, suspension, and even the original tires can mimic or contribute to wheel-related symptoms.
- NHTSA Recall 13V622000: A recall was issued for some 2014 RLX models concerning rear lower control arm bolts that may not have been properly tightened at the factory. If these bolts loosen, it can affect alignment and steering control, which might be mistaken for a wheel or tire issue.
- TSB 13-041 & Warranty Extension: Many owners reported a moaning or rubbing noise from the rear of the car. This was traced to a lack of lubrication in the P-AWS rear toe control (RTC) actuators. Acura issued service bulletins and later a warranty extension (TSBs 23-021 and 23-022) to address this by replacing the actuators. While not a wheel fault, the noise could be perceived as a wheel bearing or tire problem.
- Tire Sidewall Separation: Some owners of the 2014 and 2016 models reported issues with the stock tires experiencing premature sidewall separation or blowouts. This is a tire failure, but it highlights the stress placed on the wheel and tire assembly. Any sudden air loss or blowout can easily damage the wheel itself.
Symptoms of a Damaged RLX Wheel
A damaged wheel can present several obvious and not-so-obvious symptoms. Ignoring them can lead to poor handling, excessive tire wear, and potentially a catastrophic failure.
Warning: A significant vibration or wobble that appears suddenly is a major safety concern. Pull over as soon as it is safe and inspect your wheels and tires.
- Vibration or Shaking: This is the most common symptom. A bent or out-of-round wheel will cause a noticeable vibration in the steering wheel at certain speeds (typically 50-70 mph). If the damage is on a rear wheel, the vibration may be felt more in the seat or floor of the car.
- Difficulty Balancing: If a tire shop reports that a wheel is difficult or impossible to balance, it's a strong indicator that the wheel is bent. Even a slight bend can require an excessive amount of wheel weights to compensate, and the vibration may still be present.
- Air Loss: A slow leak that isn't caused by a puncture in the tire could be from a crack in the wheel or a poor seal between the tire and the wheel bead. This can happen if the wheel is bent or if corrosion has formed on the bead seat area.
- Visible Damage: Obvious signs like curb rash (scraping along the outer lip), peeling finish, or spokes that are clearly bent or cracked are direct indicators that the wheel's integrity may be compromised.
Buying a Used 2014-2016 RLX Wheel
Purchasing a used OEM wheel is an excellent way to save money compared to buying new from a dealer. Because the RLX wheel includes special noise-reducing technology, a used OEM wheel is often a better choice than a cheap aftermarket alternative that lacks this feature. However, careful inspection is critical.
What to Inspect on a Used Wheel
- Check for Cracks: Inspect the entire wheel, front and back, for hairline cracks. Pay special attention to the area where the spokes meet the outer rim and around the lug nut holes.
- Look for Bends: Lay the wheel on a flat surface to check for wobbles. A simple way to check for bends is to place the wheel on the ground and spin it. Look at the outer lip; it should spin true without any up-and-down movement. 🎬 Watch: A simple guide to checking for a bent wheel. Even a small bend can cause significant vibration.
- Inspect the Bead Area: Check the inner and outer bead seats (where the tire seals against the wheel) for deep corrosion, gouges, or damage. A damaged bead seat can cause a persistent slow leak.
- Signs of Previous Repair: Look for signs of welding on the back of the wheel. Welded wheels can be safe if repaired by a professional, but it's a red flag. Also, check for fresh paint that might be hiding filler or other cosmetic repairs. The finish should be consistent across the entire wheel.
- Verify Part Numbers: Ensure the wheel is the correct OEM part. The standard 18-inch wheel for the 2014-2016 RLX is part number 42800TY2A80.
Pro Tip: When buying a used wheel, ask the seller if they can put it on a wheel balancing machine. This is the best way to see if it's bent or has a significant wobble before you buy it.

Frequently Asked Questions (FAQ)
Can I use a wheel from a different Acura model on my RLX?
Possibly, but you must match all specifications exactly. The 5x120mm bolt pattern is shared with some other Acura and Honda models (like the MDX, Pilot, and Odyssey), but the offset (+50mm) and center bore (64.1mm) are critical for proper fitment. An incorrect offset can cause the wheel to rub against suspension components or the fender and can put stress on wheel bearings.
What happens if I use a wheel with the wrong offset?
Offset determines how far the wheel's mounting surface is from its centerline. A wheel with too little offset will stick out too far, potentially rubbing on the fender. A wheel with too much offset will sit too far inside the wheel well, risking contact with suspension parts like the strut or control arms. Using the wrong offset can also change the car's handling characteristics and increase wear on wheel bearings.
Do I need to replace my TPMS sensor when I replace a wheel?
Not usually. In most cases, a tire shop can carefully remove the Tire Pressure Monitoring System (TPMS) sensor from your old wheel and install it in the new one. However, the sensor's grommets and seals should be replaced, and if the sensor is old or its battery is dying, it's a good time to replace the sensor itself.
Is a refinished or remanufactured wheel as good as a new one?
A professionally remanufactured wheel can be a great value. These wheels have been stripped, inspected for cracks or bends (and repaired if necessary), and then repainted or refinished to look like new. They are often held to high standards and can be a reliable alternative to a brand new, expensive OEM wheel.
