Do you have to replace all 4 tires on AWD Ford Edge?
Not necessarily. For an AWD Ford Edge, you don’t have to replace all four tires at once, but replacing all four is often the safest way to maintain even traction and protect the drivetrain. If you replace only two tires, they should be identical in size, model, and tread depth to the existing tires and ideally mounted on the rear axle.
The question matters because Ford Edge’s all‑wheel drive system is designed to distribute torque based on wheel speed and grip. Differences in tire tread depth or circumference across axles can place extra stress on the center differential or transfer case, potentially accelerating wear. Understanding when to replace four tires versus two—and how to position any new tires—helps preserve performance, handling, and safety.
Understanding AWD on the Ford Edge
The Ford Edge uses an Intelligent AWD system that monitors wheel speed, traction, and torque needs to optimize power delivery. Because the system relies on matching tire characteristics across the front and rear axles, keeping tread depth and circumference similar is important. Mismatched tires can cause the system to compensate in ways that may wear components unevenly over time.
When to Replace All Four Tires vs. Two
Below are the key factors that influence whether you should replace all four tires or just two:
- Tread depth difference: If the wear between any two tires exceeds about 2/32 inch (1.6 mm), replacing all four is often advised to maintain even handling and minimize drivetrain stress.
- Tire model and size consistency: If you mix different tire models or sizes, replacing three or four tires is typically recommended to avoid diameter differences that can confuse the AWD system.
- Current wear pattern: If one axle has significantly more wear than the other, replacing all four helps restore uniform grip and stability.
Concluding: In practice, many Ford Edge owners replace all four tires to ensure uniformity, but if you replace only two, choose the newest, most identical tires possible and install them on the rear axle.
Practical guidelines for replacing tires on an AWD Edge
The following steps reflect common automotive guidance and Ford recommendations for AWD vehicles. Always consult your owner’s manual or a Ford service professional for model-year specifics.
- If replacing two tires, ensure they match the existing tires in size, load index, speed rating, and tread pattern, and install them on the rear axle.
- Avoid mixing tire brands or tread patterns on an AWD Edge when possible, especially across axles.
- Prefer replacing all four tires at the same time if you can, to guarantee identical diameter and grip.
- After installing tires, have the vehicle’s alignment checked if you notice uneven wear or handling changes.
Concluding: Following these steps helps maintain AWD performance and reduces the risk of drivetrain wear due to mismatched tires.
Tips for Maintenance and Safety
Beyond replacement decisions, these practices help preserve AWD health on your Ford Edge:
- Regularly rotate tires according to the manufacturer’s schedule to promote even wear.
- Check tire pressure monthly and adjust to the recommended specifications for your load and speed.
- Monitor tread depth across all tires and plan replacements before depth drops below 4/32 inch (3.2 mm) on any tire for optimal safety.
Concluding: Proactive maintenance supports consistent performance and helps prevent drivetrain complications related to tire wear and diameter differences.
Summary
For an AWD Ford Edge, you don’t have to replace all four tires every time, but doing so is often the wisest move to ensure uniform grip and protect the AWD system. If you must replace only two, match them carefully to the existing tires and place them on the rear axle. Always consider the wear difference, tire models, and diameter matching, and consult your owner’s manual or a Ford technician for model-year specific guidance. Regular maintenance, including rotation and proper inflation, further supports AWD reliability and safe handling.
