Ford Edge's tire sizes are 245/60R18, 245/55R19, 245/50R20, and 265/40R21. The method to distinguish tires and the meaning of tire models are introduced as follows: Method to distinguish tires: The model of the tire can be identified based on the data on the side of the car tire. Generally, the side of the tire will indicate the tire's width, aspect ratio, tire type, and the applicable size of the tire. When purchasing tires, observe the tire data before making a purchase. Meaning of tire models: There will be a series of numbers marked on the side of the tire. These numbers are separated, usually the first three digits refer to the width of the car tire. Generally, the width of the tire ranges between 145 and 285. Additionally, different engine displacements can also lead to the use of different tire specifications.

I've been driving the Edge for several years and remember the tire specifications clearly. The base model usually comes with 245/60R18 tires. When I changed tires last time, the mechanic reminded me not to alter the size randomly as it could affect braking and fuel efficiency; the 245 indicates the tire width in millimeters, 60 represents the aspect ratio, and 18 is the wheel diameter in inches. Later I found that higher trim levels like the ST-line might use 245/50R20 tires, which provide better stability but cost more. For daily commuting, the original size ensures comfort with significantly less bumpiness. If you're unsure, checking the label on the door jamb is the most accurate way to avoid unnecessary trouble. Regular tire pressure checks are also crucial - I measure mine monthly to prevent premature wear and extend tire life, which is vital for safe driving.

From the perspective of car enthusiasts, the Edge's tire specifications are quite detailed. The 245/60R18 is common in entry-level models, with the 'R' indicating radial design for improved handling. The 245/50R20 is found on sportier versions, featuring larger rims for better grip but slightly higher fuel consumption. During my tests with different sizes, I noticed that minor changes can affect ABS performance, so it's important to stick with the factory-matched setup. When buying a car, I also pay attention to how tire brands impact pricing—replacing a set with original tires costs about 800 yuan per tire and can last several years. For highway or mountainous driving, stable tire sizes are hassle-free. Don’t overlook tread depth to ensure anti-slip performance—safety first, after all.

My experience in car repair tells me that most Edge owners come to change tires with the size 245/60R18, while the high-end models have 245/50R20. Incorrect sizes may cause uneven wear or trigger warnings, commonly like ABS faults. I recommend checking tire pressure and wheel balance during regular maintenance; if confirming the size yourself, refer to the accurate data on the door placard. The original design avoids issues, so don't opt for cheaper, mismatched sizes when changing tires, as it affects driving safety and the suspension system. Maintaining the original size prolongs tire life.
