Hey guys! If you're rocking a 2018 Ford Edge SEL with All-Wheel Drive (AWD), one of the most crucial things to know is the right tire size. Getting this wrong can mess with your car's performance, safety, and even its computer systems. So, let's dive deep into everything you need to know about the correct tire size for your ride. Let’s get started!

Understanding Tire Size Designations

Before we pinpoint the exact tire size for your 2018 Ford Edge SEL AWD, it's essential to understand what those numbers and letters on the sidewall actually mean. Decoding these designations will help you make informed decisions when it's time to replace your tires. Typically, a tire size is represented in a format like P245/60R18, where each segment provides specific information.

• P (or nothing): This indicates the tire type. "P" stands for Passenger, meaning the tire is designed for passenger vehicles. If there's no letter, it usually means the tire is a European metric tire, which may have slightly different load capacities but is generally compatible.
• 245: This number represents the tire's section width in millimeters. In this case, the tire is 245 millimeters wide from sidewall to sidewall.
• 60: This is the aspect ratio, which tells you the height of the tire's sidewall as a percentage of its section width. So, 60 means the sidewall height is 60% of the 245mm width.
• R: This letter indicates the tire's construction type. "R" stands for Radial, which is the most common type of tire construction for modern vehicles. Radial tires have plies that run radially across the tire from bead to bead.
• 18: This number represents the wheel diameter in inches. This tire is designed to fit an 18-inch wheel.

Understanding these components is critical because using the wrong size can lead to several issues, including inaccurate speedometer readings, compromised handling, and potential damage to your vehicle's drivetrain. Always check your vehicle's door placard or owner's manual for the recommended tire size to ensure optimal performance and safety.

OEM Tire Size for the 2018 Ford Edge SEL AWD

Alright, let’s cut to the chase. The Original Equipment Manufacturer (OEM) tire size for the 2018 Ford Edge SEL AWD is usually 235/65R17 or 245/60R18, depending on the specific wheel configuration that came with your vehicle from the factory. These sizes ensure the vehicle operates as intended by Ford's engineers.

• 235/65R17: This size means the tire has a width of 235 millimeters, a sidewall height that is 65% of the width, and fits a 17-inch wheel. This option often provides a comfortable ride due to the taller sidewall, which absorbs more of the road's imperfections.
• 245/60R18: This indicates a tire with a width of 245 millimeters, a sidewall height that is 60% of the width, and fits an 18-inch wheel. This option may offer slightly better handling and a more responsive feel due to the shorter sidewall.

To be absolutely sure, check the sticker on your driver's side doorjamb. This sticker contains vital information about your vehicle, including the recommended tire size and inflation pressures. You can also find this information in your owner's manual. Using the OEM tire size ensures that your speedometer and odometer readings are accurate, and that your vehicle's safety systems, such as ABS and traction control, function correctly.
