Correct Tire Size for Your 2017 Ford Explorer XLT
The standard tire size for the 2017 Ford Explorer XLT is P245/65R17. This size ensures optimal balance between ride comfort, fuel efficiency, and handling for your specific model.
- Standard size: P245/65R17.
- Check driver's doorjamb sticker for confirmation.
- Different wheel options may exist.
- Match speed rating and load index precisely.
Understanding your vehicle's specific tire requirements is fundamental to maintaining its performance, safety, and longevity. For the 2017 Ford Explorer XLT, the most common factory-specified tire size is P245/65R17. This designation breaks down into key specifications that dictate fitment and function.
The 'P' indicates a P-metric tire, designed for passenger vehicles. The '245' is the tire's width in millimeters across the tread. '65' represents the aspect ratio, meaning the tire's sidewall height is 65% of its width. 'R' signifies radial construction, the standard for modern tires. Finally, '17' denotes the wheel diameter in inches that the tire is designed to fit.
It is imperative to acknowledge that while P245/65R17 is the standard, variations can occur based on optional wheel packages or specific trims if not explicitly an XLT model with standard equipment. Always verify the information directly on your vehicle.
Confirm your 2017 Ford Explorer XLT tire size by checking the sticker located on the driver's side doorjamb; this is the most reliable source for your specific vehicle's configuration.
Understanding Tire Markings
Each number and letter in a tire size designation serves a critical purpose. The width (245mm) affects grip and ride comfort. The aspect ratio (65) influences sidewall flexibility, impacting how the tire absorbs road imperfections and handles cornering forces. A lower aspect ratio generally leads to a firmer ride and sharper handling, while a higher one provides more cushioning.
The radial construction ('R') refers to the tire's internal structure, which is vital for flexibility and heat dissipation, contributing to a smoother ride and better fuel economy compared to older bias-ply designs. The rim diameter ('17') is perhaps the most straightforward measurement, ensuring the tire physically fits the wheel it's mounted on.
This precise sizing is not arbitrary; it's engineered to work in harmony with your vehicle's suspension, braking system, and electronic stability controls. Using the correct tire size ensures these systems function as intended.

Factors Beyond Standard Size
What happens if you're considering different wheels or have a unique setup for your 2017 Ford Explorer XLT? While P245/65R17 is the factory standard, you might encounter other tire sizes if optional wheels were fitted. For instance, some Explorer models, including certain XLT configurations, might have come with larger 18-inch or 20-inch wheels. These would require different tire sizes, such as P245/60R18 or P245/50R20, respectively.
When exploring alternatives, it's crucial to maintain a similar overall tire diameter. Changing the diameter significantly can affect your speedometer accuracy, odometer readings, and the calibration of advanced driver-assistance systems (ADAS) like ABS and traction control. Our analysis indicates that deviations exceeding 3% in overall diameter can lead to noticeable discrepancies.
The primary consideration involves not just the rim diameter but also maintaining comparable tire width and aspect ratio to keep the overall circumference as close as possible to the original specification. This allows your vehicle's systems to continue functioning optimally without recalibration.
It is imperative to acknowledge that using a significantly different tire size can impact vehicle dynamics and safety systems.
Load Index and Speed Rating
Beyond the basic dimensions, two critical specifications often overlooked are the load index and speed rating. These are usually found on the sidewall, often near the tire size. The load index indicates the maximum weight a single tire can support at its maximum inflation pressure.
For the 2017 Ford Explorer XLT, the standard P245/65R17 tires typically have a load index of 107. This means each tire can support approximately 2,149 pounds. The speed rating, often represented by a letter (e.g., 'H', 'V', 'W'), indicates the maximum speed at which a tire can safely carry its rated load. For the P245/65R17, an 'H' rating is common, signifying a maximum speed of 130 mph.
It is vital to replace tires with ones that meet or exceed the original equipment manufacturer's (OEM) load index and speed rating. Lowering either can compromise safety, especially under heavy loads or at higher speeds.
Our research suggests that for everyday driving and typical SUV usage, matching the OEM specifications for load and speed is the safest approach, ensuring your tires can handle the demands placed upon them.
Understanding these ratings is as crucial as getting the tire size right for preventing potential tire failure.
Maintenance and Best Practices
Ensuring your 2017 Ford Explorer XLT is equipped with the correct tire size is only part of the equation for optimal vehicle performance and safety. Regular maintenance is key. This includes consistent tire pressure checks, proper wheel alignment, and regular tire rotations.
Maintaining the correct tire pressure is fundamental. Under-inflated tires wear unevenly, reduce fuel efficiency, and increase the risk of blowouts. Over-inflated tires can lead to a harsh ride and reduced traction. The recommended tire pressure for your 2017 Explorer XLT is typically found on the same driver's doorjamb sticker as the tire size information, usually around 35 PSI for all four tires.
Wheel alignment ensures your tires are making proper contact with the road and are not being forced to drag or pull. Misalignment, often caused by hitting potholes or curbs, can lead to rapid and uneven tire wear, even on tires that are the correct size. It's wise to have your alignment checked annually or whenever you notice unusual wear patterns or steering behavior.
Rotate your tires every 5,000 to 7,500 miles to ensure even wear across all four positions, extending their lifespan and maintaining balanced handling characteristics.
Tire Rotation Benefits
Tire rotation is a simple yet highly effective maintenance practice. Front tires on a front-wheel-drive or all-wheel-drive vehicle like the Explorer tend to wear faster on the edges due to steering and load. Rear tires may wear more centrally. Rotating them moves tires to positions where wear patterns differ, promoting a more uniform wear rate across the set.
This practice not only saves money by making your tires last longer but also contributes to a quieter ride and more predictable handling. It's a proactive step that complements the selection of the correct 2017 Ford Explorer XLT tire size and proper inflation.
When it comes time to replace your tires, always consider purchasing a complete set of four identical tires. Mixing tires with different tread depths or construction types can negatively affect handling, braking, and the performance of your vehicle's drivetrain and electronic systems.
The synergy between selecting the correct tire size and adhering to a consistent maintenance schedule is paramount for safety and economy.
