Understanding Your 2017 Ford Explorer Tire Size

The correct 2017 Ford Explorer tire size is essential for maintaining your SUV's optimal performance, safety, and fuel economy. For this model year, the standard tire sizes typically align with its trim levels and original equipment specifications. Knowing these dimensions ensures you select tires that fit correctly and function as intended by the manufacturer.

  • Standard sizes are crucial for OE fitment.
  • Correct size enhances safety and performance.
  • Check sidewall or doorjamb for exact specs.
  • Optional sizes may affect speedometer calibration.

When you look at a tire's sidewall, you'll see a series of numbers and letters, like P245/65R17. This code indicates the tire's specifications. For a 2017 Ford Explorer, you'll most commonly find sizes that include a 17-inch wheel diameter. However, depending on the trim (e.g., Base, XLT, Limited, Sport), different wheel sizes like 18-inch or 20-inch might have been factory-equipped. Understanding this nomenclature is fundamental to selecting the right replacement tires.

The primary consideration involves matching the tire's overall diameter and width to the vehicle's suspension and body clearances. An incorrect tire size can lead to rubbing, speedometer inaccuracies, or adverse effects on handling and braking. Such precision is paramount for a vehicle like the Explorer, designed for diverse driving conditions.

Decoding Tire Size Markings

Let's break down that example: P245/65R17.

  • P: Indicates the tire is for Passenger vehicles.
  • 245: The tire's width in millimeters, measured from sidewall to sidewall.
  • 65: The aspect ratio, which is the tire's sidewall height as a percentage of its width. Here, it's 65% of 245mm.
  • R: Denotes Radial construction.
  • 17: The diameter of the wheel (rim) in inches that the tire fits.

This mechanism is critical for ensuring a proper fit and performance profile.

Common 2017 Ford Explorer Tire Sizes and Fitment

What are the most common tire sizes you'll encounter on a 2017 Ford Explorer?

For the 2017 Ford Explorer, the standard factory-installed tire sizes commonly depend on the trim level. The most frequent sizes you'll find are designed to optimize ride comfort and fuel efficiency for everyday driving. It's vital to confirm the exact size for your specific vehicle to avoid compatibility issues and ensure optimal road contact.

The standard sizes often revolve around 17-inch and 18-inch wheel diameters. For instance, a common fitment for many 2017 Explorer models is P245/65R17. Higher trims, or vehicles equipped with specific appearance or towing packages, might feature larger wheels. A popular alternative for 18-inch wheels is P255/60R18, offering a slightly different aesthetic and potentially altered ride characteristics.

Optional and Upgrade Sizes

Some owners opt for larger wheels, such as 20-inch rims. If your 2017 Explorer came with or you intend to fit 20-inch wheels, a typical tire size would be P255/50R20. When considering these larger sizes, it is imperative to acknowledge that they can affect the vehicle's speedometer accuracy and odometer readings if the overall tire diameter is significantly different from the original equipment. Always verify these differences using a tire size RPM calculator or consult a professional.

Always check your vehicle's doorjamb sticker or owner's manual for the most accurate tire size information specific to your 2017 Ford Explorer configuration.

The primary consideration involves selecting a tire that maintains an equivalent overall diameter to the original equipment to prevent speedometer errors. This is not just about fitting the wheel; it's about maintaining the integrity of the vehicle's electronic systems.

Ensuring the correct tire size is paramount for safety, performance, and the longevity of your vehicle's components.

Why Correct Tire Size Matters for Your Explorer

Why is sticking to the correct tire size for your 2017 Ford Explorer so critical?

Selecting the right tire size directly impacts your SUV's safety, handling, and overall efficiency. Tires are the single point of contact between your vehicle and the road; their dimensions influence braking distances, traction in various conditions, and stability during maneuvers. Using an incorrect size can compromise these critical functions, making your vehicle less predictable and potentially unsafe.

One of the most overlooked consequences of incorrect tire sizing is its effect on the vehicle's electronic systems. The Antilock Braking System (ABS), Traction Control, and even the speedometer and odometer rely on the wheel speed sensors interpreting consistent rotational data. If you install tires with a significantly different overall diameter than what the vehicle was designed for, these systems can malfunction or provide inaccurate readings. Understanding this principle is fundamental.

Practical Impacts of Wrong Tire Sizes

Beyond safety systems, the consequences can be practical and costly:

  • Speedometer/Odometer Inaccuracy: Tires that are too large or too small will cause your speedometer to read incorrectly, affecting your actual speed and distance traveled. This can lead to speeding tickets or incorrect mileage tracking.
  • Fuel Economy: Tires with different rolling resistance or overall diameter may cause your engine to work harder, negatively impacting your gas mileage.
  • Handling and Ride Comfort: An incorrect aspect ratio or width can alter how the tire flexes and grips the road, potentially leading to a harsher ride, reduced cornering stability, or increased road noise.
  • Component Wear: Incorrectly sized tires can place undue stress on suspension components, bearings, and drivetrain parts, leading to premature wear and potential damage.

Verify the load and speed ratings on any new tire to ensure they meet or exceed your 2017 Ford Explorer's original specifications for safe operation.

Our analysis indicates that neglecting tire size specifications is a common oversight, yet it carries significant implications for vehicle performance and driver confidence.
