If you're searching for 19-inch wheels for Infiniti Q50, the first thing to know is compatibility. Not all 19" rims will fit every Q50 model year or trim due to variations in bolt pattern (5x114.3), center bore (66.1mm), and required offset (typically +34 to +45). Choosing the wrong setup can lead to clearance issues, vibration, or even damage to suspension components. This guide breaks down everything you need to know—from OEM specs to aftermarket upgrades—so you can make an informed decision without compromising safety or performance.
Understanding Infiniti Q50 Wheel Specifications
The Infiniti Q50 has been produced from 2013 to present, with subtle changes across generations that affect wheel compatibility. When upgrading to 19-inch wheels on a Q50, it's critical to understand five core specifications: diameter, width, bolt pattern, offset, and center bore.
Diameter and Width Options
While factory trims offer 17", 18", and 19" options, many owners opt for 19" wheels as a balance between aggressive styling and ride comfort. The most common 19" configuration is 19x8.5 front and 19x9 rear, though staggered setups like 19x9.5 rear are used on higher-performance models such as the Red Sport 400.
- Standard Fit: 19x8.5 ET40 (front), 19x8.5 ET40 (rear) – common on non-staggered OEM setups
- Staggered Fit: 19x8.5 ET40 (front), 19x9.5 ET35 (rear) – often found on sport trims
- Aftermarket Range: Aftermarket allows widths from 19x8 up to 19x11 depending on fender clearance and suspension mods
Bolt Pattern (PCD): 5x114.3
All Q50 models use a 5-lug bolt pattern with 114.3mm pitch circle diameter. This is standard across most Nissan/Infiniti platforms of this era, making many aftermarket wheels compatible. However, some wheels designed for other brands may have the same PCD but different center bores or load ratings, so verification is essential.
Offset (ET): Critical for Clearance
Wheel offset determines how far the wheel sits in relation to the hub mounting surface. For the Q50, typical OEM offsets range from +34mm to +45mm. Going too low (negative offset) pushes the wheel outward, increasing strain on bearings and potentially causing rubbing against fenders or suspension arms.
| Trim Level | Factory Wheel Size | Offset (ET) | Tire Size |
|---|---|---|---|
| Q50 Base (2014–2024) | 17x7.5 or 18x8 | +45 | 225/55R17 or 225/50R18 |
| Q50 Luxury/Sport (19") | 19x8.5 | +40 | 225/45R19 |
| Q50 Red Sport 400 | 19x8.5 (F), 19x9.5 (R) | +40 / +35 | 225/45R19 (F), 245/40R19 (R) |
| Aftermarket Max Recommended* | 19x9.5 (F), 19x10.5 (R) | +20 to +35 | 255/35R19 (R) |
Center Bore: Hub-Centric vs. Lug-Centric
The Q50 requires a 66.1mm center bore to be hub-centric, meaning the wheel centers on the axle hub rather than relying solely on lug nuts. Many aftermarket wheels come with larger bores (e.g., 73mm) and include hub-centric rings to adapt them properly. Running non-hub-centric wheels without adapters can cause vibrations at high speeds.
OEM vs. Aftermarket 19-Inch Wheels
When considering Infiniti Q50 19-inch OEM wheels, there are advantages in terms of guaranteed fitment, load rating, and finish quality. However, they’re often heavier and more expensive than comparable aftermarket options.
OEM Wheel Advantages ✅
- Guaranteed Compatibility: Designed specifically for the Q50’s suspension and brake system
- Load Rating: Typically rated above 600kg per wheel, suitable for daily driving and high-speed stability
- Warranty Support: Covered under manufacturer warranty if purchased new through dealer channels
- Resale Value: Maintains originality, which matters to some buyers
Aftermarket Benefits ⚙️
- Weight Reduction: Flow-formed or forged wheels (like Apex or TSW) can save 15–25 lbs per corner, improving acceleration and braking
- Design Flexibility: More finishes (gloss black, bronze, machined face) and styles (deep concave, split-spoke)
- Cost-Effective Packages: Some vendors offer wheel-and-tire bundles priced below OEM replacement costs
- Performance Tuning: Wider widths and lower offsets allow better grip with sticky tires
Common Aftermarket Brands Offering Q50 19" Wheels

Tire Sizing for 19-Inch Q50 Wheels
Selecting the right tire size is just as important as choosing the correct rim. Incorrect sizing affects speedometer accuracy, fuel economy, and handling.
Stock Tire Sizes for 19" Trims
- Non-Staggered: 225/45R19 (front and rear)
- Staggered (Red Sport): 225/45R19 (front), 245/40R19 (rear)
Popular Upgrade Tire Sizes
Some enthusiasts widen the stance using slightly wider tires while staying within safe limits:
- Front: 235/40R19 or 245/40R19 (check inner strut clearance)
- Rear: 255/35R19 or 265/35R19 (requires minimal fender modification on stock suspension)
Tire Diameter Matching
To maintain accurate speed readings and prevent traction control errors, keep overall tire diameter within ±3% of stock. Use a tire size calculator1 to compare revolutions per mile.
Installation Tips and Common Mistakes 🔧
Installing 19-inch wheels on your Q50 seems straightforward, but several pitfalls can compromise safety and performance.
Mistake #1: Ignoring Hub-Centric Rings
As mentioned, the Q50 is hub-centric. Even if the bolt pattern matches, skipping hub rings means the wheel isn’t centered precisely, leading to imbalance and vibration. Always install appropriate 66.1mm-to-bore adapters if needed.
Mistake #2: Incorrect Torque or Pattern
Infiniti specifies 83 lb-ft (113 Nm) for lug nut torque. Under-torquing risks loosening; over-torquing can warp rotors or strip threads. Use a star pattern and re-check after 50 miles.
Mistake #3: Skipping Alignment
Changing wheel width or offset alters scrub radius and camber. A post-installation alignment ensures even tire wear and predictable handling.
Mistake #4: Assuming All 19" Wheels Fit
Just because a wheel is listed as “for Q50” doesn’t guarantee fitment. Verify spoke clearance behind the wheel, especially with big brake kits. Some deep-dish wheels interfere with calipers or suspension arms.
Can You Run 19-Inch Wheels on All Q50 Models?
Yes, 19-inch wheels are compatible with all Infiniti Q50 trims, but not all suspensions handle them equally well. Base models with softer springs and shocks may feel harsher with larger wheels due to reduced sidewall height. Consider pairing 19" wheels with adaptive dampers (available on higher trims) for optimal ride quality.
Ride Comfort Trade-offs ⚠️
Larger wheels reduce tire sidewall height, which decreases cushioning from road imperfections. On rough roads, 19" setups may transmit more vibration into the cabin compared to 17" or 18" wheels. Drivers in areas with poor pavement should consider:
- Using tires with reinforced sidewalls (ZR-rated or XL)
- Avoiding ultra-low-profile tires (below 35-series aspect ratio) unless lowered
- Opting for slightly smaller diameters (18") for daily-driven comfort
Finding Used or Replacement 19" Wheels
If you’re replacing a damaged OEM wheel or sourcing a full set affordably, used markets exist—but require caution.
Where to Look
- OEM Dealerships: Can order exact replacements, though costly ($300–$600 each)
- Online Marketplaces: Sites like eBay list individual or full sets; verify condition carefully
- Salvage Yards: May have wheels from totaled Q50s; inspect for bends or cracks
- Forums: r/q50 or Infiniti forums sometimes have members selling take-offs
What to Check Before Buying Used
- Cracks or Weld Damage: Especially near spokes or valve stem holes
- Bend Tests: Roll the wheel on a flat surface to detect wobble
- Finish Integrity: Peeling paint or curb rash can indicate structural stress
- TPMS Compatibility: Ensure sensors can be transferred or replaced
Seasonal Wheel Strategies 🌍
Many Q50 owners run dedicated winter wheels. Using a separate set of 18" or 19" rims with snow tires avoids wear on summer wheels and improves cold-weather performance.
Benefits of a Second Set
- Prolongs life of expensive summer wheels
- Allows use of studless ice tires optimized for low temps
- Eliminates repeated mounting/dismounting, reducing bead damage risk
Suggested Winter Setup
- Size: 18x8 or 19x8.5 (same offset as stock)
- Tire: 225/50R18 or 225/45R19 all-weather or winter tire
- Material: Steel or basic alloy (cheaper, more impact-resistant)
Legal and Safety Considerations ⚖️
No regulation bans 19-inch wheels on Q50s, but local laws may restrict modifications affecting vehicle dimensions. In some regions:
- Wheels cannot extend beyond fender lines
- Tire tread must remain above minimum depth (2/32" in US)
- Speedometer error must stay within legal tolerance
Always confirm compliance with state/provincial rules before installing wide or low-offset wheels.
