Drivers searching for precise specifications for their 2017 Honda Accord LX often prioritize tire size above all else, as this metric dictates speedometer accuracy, load capacity, and overall safety. Getting the correct diameter and width ensures optimal handling in various weather conditions and prevents unnecessary wear on the suspension components. This guide breaks down the specific tire size for the base model, explaining why these measurements matter for daily driving and long-term maintenance.
Factory Specifications for the 2017 Accord LX
The 2017 Honda Accord LX, the entry-level trim of the popular mid-size sedan, rolled off the assembly line with a specific tire size designed to balance comfort, efficiency, and grip. Understanding these numbers is crucial when shopping for replacements or checking the validity of your current setup. The measurements are not arbitrary; they are the result of extensive engineering tests conducted by Honda to ensure the vehicle performs as intended under normal driving conditions.
Decoding the Tire Size Code
If you look at the driver’s door jamb or the current tires on your LX, you will find a code that might look confusing at first glance. This code provides all the necessary information about the tire’s dimensions and capabilities. For the 2017 Honda Accord LX, the standard tire size is P215/55R17.
Dimensions in Imperial Measurements
While the metric code is standard globally, many drivers in the United States prefer to think in inches regarding diameter and width. The 215mm width converts to approximately 8.46 inches, and the 17-inch rim size remains the same. The overall diameter of the tire is roughly 26.7 inches. This specific combination ensures the speedometer calculates distance accurately, as changing the diameter without recalibrating the computer can lead to significant speedometer errors over time.
Performance and Handling Implications
The aspect ratio of 55% is a key factor in the driving dynamics of the LX. This moderate profile provides a comfortable ride by allowing the tire to absorb road imperfections, such as potholes and minor cracks, effectively. A lower aspect ratio (like 45 or 50) would result in a stiffer ride and better handling response, but the 55-series ratio aligns perfectly with the Accord LX’s design philosophy of prioritizing passenger comfort and quietness without sacrificing too much control.
Importance of Load Index and Speed Rating
Beyond the basic dimensions, the load index and speed rating are critical safety numbers you must verify when replacing tires. The load index indicates how much weight the tire can safely support when properly inflated, while the speed rating denotes the maximum speed the tire can sustain without failing. For the 2017 Honda Accord LX, the tires typically feature a load index of 97 or 98 and a speed rating of V.
Load Index 97: Equates to a maximum load of 730 kilograms (1,609 pounds).
