The right tire size ensures that your vehicle handles properly and that you get the best fuel efficiency possible. Here’s a breakdown of what you need to know about the tire sizes for different model years of the QX50.
Stock Tire Sizes
The stock tire size for the Infiniti QX50 can vary depending on the model year and trim level. Below is a table summarizing the stock tire sizes for various years:
| Model Year | Tire Size | Tire Type |
|---|---|---|
| 2018 | 225/60R18 | All-Season |
| 2019 | 225/60R18 | All-Season |

Understanding Tire Size Notation
The tire size notation, such as 225/60R18, can seem confusing at first, but it’s pretty straightforward once you break it down:
- 225: This number represents the width of the tire in millimeters. In this case, the tire is 225 mm wide.
- 60: This is the aspect ratio, which is the height of the sidewall as a percentage of the width. A 60 aspect ratio means the sidewall height is 60% of the tire’s width.
- R: This letter indicates that the tire is of radial construction, which is the most common type used today.
- 18: This number indicates the diameter of the wheel rim in inches that the tire is designed to fit.
Why Tire Size Matters
Choosing the correct tire size for your QX50 is not just a matter of preference; it has a direct impact on your vehicle’s performance and safety. Here are a few reasons why:
- Handling: The right tire size contributes to optimal handling. A tire that is too wide or too narrow can affect steering response and stability.
- Fuel Efficiency: Properly sized tires can improve fuel efficiency. Oversized tires can create more rolling resistance, leading to increased fuel consumption.
- Safety: Using the manufacturer-recommended tire size ensures that your vehicle’s braking and traction systems work as intended. Mismatched tires can lead to unpredictable handling, especially in adverse conditions.
Aftermarket Tire Considerations
If you’re considering upgrading to aftermarket tires, keep in mind that while you can change the size, it’s crucial to stay within a reasonable range. Deviating too far from the stock size can lead to issues such as speedometer inaccuracies, increased wear on suspension components, and compromised safety.
Always consult your owner’s manual or a tire professional before making any changes. If you’re unsure, stick with the stock sizes listed above to maintain the integrity of your Infiniti QX50.
