Laufenn S FIT AS LH01 All Season Radial Tire 245/45R17 99W

Tire 245/45R17 is a widely used tire size for various types of vehicles, particularly passenger cars and SUVs. The numbers and letters in this tire size designation provide specific information about the tire's dimensions and characteristics.

The "245" in the tire size refers to the tire's width, measured in millimeters. In this case, the tire width is 245 millimeters, or approximately 9.6 inches. This width provides a balance between performance, comfort, and fuel efficiency, making it a popular choice for a wide range of vehicles.

The "45" in the tire size represents the tire's aspect ratio, which is the ratio of the tire's sidewall height to the tire's tread width. In this case, the aspect ratio is 45, meaning the sidewall height is 45% of the tread width. A lower aspect ratio, such as 45, typically results in a sportier, more responsive handling feel, but may also lead to a slightly harsher ride quality.

The "R" in the tire size indicates that the tire is of a radial construction, the most common type of tire construction used in modern vehicles. Radial tires have crisscrossing layers of steel or other reinforcing materials in the tire's carcass, providing better handling, improved treadwear, and higher load-carrying capacity compared to older bias-ply tire designs.

The "17" in the tire size refers to the wheel diameter, in this case, 17 inches. This is a common wheel size for many passenger cars and SUVs, providing a good balance between performance, ride comfort, and aesthetics.

The 245/45R17 tire size is often used on a wide variety of vehicles, including compact sedans, midsize sedans, sports coupes, and small to medium-sized SUVs. It offers a combination of attributes that make it a popular choice among drivers, such as good handling, responsive steering, and a comfortable ride, all while providing adequate tread life and fuel efficiency.

When selecting replacement tires, it's important to consult your vehicle's owner's manual or tire information placard to ensure you choose the correct tire size that meets the manufacturer's specifications. Using the wrong tire size can negatively impact your vehicle's performance, handling, and safety.

In conclusion, the 245/45R17 tire size is a versatile and widely used option that provides a balance of performance, comfort, and efficiency for a range of vehicles. Understanding the meaning behind the tire size designation can help you make an informed decision when choosing the right tires for your car or SUV.
