2018 Infiniti Q50 Tire Size
When it comes to the 2018 Infiniti Q50, understanding the right tire size is crucial for performance, safety, and overall driving experience. The Q50 is a luxury sedan that combines style with performance, and the right tires play a significant role in achieving that balance.
Stock Tire Sizes
The stock tire sizes for the 2018 Infiniti Q50 vary depending on the trim level. Here’s a quick breakdown:
| Trim Level | Front Tire Size | Rear Tire Size |
|---|---|---|
| Q50 2.0t | 225/55R17 | 225/55R17 |

| Q50 Red Sport 400 | 245/40R19 | 255/35R19 |
Understanding Tire Size Notation
Tire sizes can seem confusing at first glance, but once you break down the numbers, it’s pretty straightforward. The size notation, like 225/55R17, can be interpreted as follows:
- 225: This is the width of the tire in millimeters.
- 55: This is the aspect ratio, which is the height of the sidewall as a percentage of the width. In this case, the sidewall height is 55% of 225mm.
- R: This indicates that the tire is of radial construction.
- 17: This is the diameter of the wheel in inches that the tire is designed to fit.
Why Tire Size Matters
Choosing the correct tire size for your 2018 Infiniti Q50 is not just about aesthetics; it’s about performance and safety. Here are some key points to consider:
- Handling: The right tire size affects how your car handles. Wider tires (like those on the Q50 Red Sport) provide better grip, especially during cornering.
- Ride Comfort: The aspect ratio plays a role in ride comfort. A higher aspect ratio (like on the Q50 2.0t) typically means a softer ride, while a lower aspect ratio can lead to a firmer ride.
- Fuel Efficiency: Tire size can impact fuel efficiency. Wider tires can create more rolling resistance, which may affect your gas mileage.
- Speedometer Accuracy: Changing tire sizes can also affect your speedometer readings. If you go with a size that’s significantly different from stock, it can throw off your speedometer and odometer.
Replacement Tires
When it’s time to replace the tires on your Q50, stick to the recommended sizes for optimal performance. If you’re considering an upgrade, consult with a tire professional to ensure compatibility with your vehicle’s specifications.
For the best results, always refer to your owner’s manual for the manufacturer’s recommendations. If you’re unsure, a quick visit to a local tire shop can help clarify your options. Remember, the right tires can make all the difference in how your Infiniti Q50 performs on the road.
