Selecting the correct dimensions ensures your speedometer remains accurate and your suspension geometry stays within factory specifications for safety.
Selecting the right set of tires for your SUV is one of the most impactful maintenance decisions you can make. You likely agree that the way your vehicle grips the road affects everything from your morning commute to your weekend camping trips.
I promise to break down every technical detail regarding the 2017 ford explorer tire size so you can shop with total confidence. We will look at trim-specific measurements, load capacities, and the specific tools you need to handle a tire change at home.
In this guide, we will preview the various wheel options available for this model year and explain why those numbers on the sidewall matter. Whether you are looking for highway comfort or off-road durability, the right information starts here.
Understanding the 2017 Ford Explorer Tire Size Options
Ford designed the 2017 Explorer to be a versatile family hauler, which is why there isn’t just one single tire size for the entire lineup. The size you need is dictated primarily by the trim level and the wheel package that came from the factory.
Most Base and XLT models left the assembly line equipped with 18-inch wheels. These wheels provide a thicker sidewall, which often results in a softer, more cushioned ride over potholes and gravel roads.
Higher trims like the Limited, Sport, and Platinum usually feature 20-inch wheels. While these look more aggressive and offer sharper handling, they require a lower-profile tire that can feel slightly firmer on the road.
The Standard 18-Inch Fitment
For the majority of owners, the 245/60R18 is the standard 2017 ford explorer tire size found on the Base and XLT trims. This size offers a great balance of fuel efficiency and all-season traction.
If you are a DIYer looking to buy replacements, this size is widely available from almost every major manufacturer. It provides ample “meat” on the sidewall to protect your rims from curb rash during tight parking maneuvers.
The Premium 20-Inch Fitment
If you own a Sport or Platinum edition, your 2017 ford explorer tire size will likely be 255/50R20. This wider footprint helps the Explorer feel more planted during high-speed highway driving and cornering.
Note that the 20-inch tires are often more expensive than their 18-inch counterparts. However, they are essential for maintaining the performance characteristics of the 3.5L EcoBoost engine found in the Sport trim.
Decoding the Sidewall: What the Numbers Mean
When you look at the side of your tire, you see a string of numbers like 245/60R18 105H. Understanding these is vital for safety, especially when carrying heavy loads or towing a trailer.
The first number, 245 or 255, represents the section width in millimeters. A wider tire generally provides more contact with the road but can slightly decrease fuel economy due to increased rolling resistance.
The second number, 60 or 50, is the aspect ratio. This is the height of the sidewall expressed as a percentage of the width. A lower number means a “shorter” tire profile, which is common on the 20-inch performance wheels.
Load Index and Speed Rating
For a heavy SUV like the Explorer, you must pay attention to the load index. Most 2017 models require a rating of 105 or higher, meaning each tire can support roughly 2,039 pounds.
The speed rating, usually denoted by a letter like H (130 mph) or V (149 mph), tells you the maximum speed the tire can safely maintain. Never “downgrade” your speed rating, as this can lead to excessive heat buildup and potential tire failure.
The Importance of the “R”
The “R” in the size string stands for radial construction. This is the standard for modern passenger vehicles, providing better tread wear and a cooler running temperature compared to old bias-ply designs.
Choosing the Right Tire Type for Your Lifestyle
Knowing your 2017 ford explorer tire size is only half the battle; you also need to choose the right tread pattern. Your choice should depend on where you spend most of your time driving.
All-Season tires are the most common choice for Explorer owners. They are designed to handle wet and dry pavement while providing a quiet ride and long-lasting tread life for daily commuting.
If you live in the “Rust Belt” or areas with heavy snowfall, consider a dedicated winter tire. These use a softer rubber compound that stays flexible in freezing temperatures, offering significantly better stopping distances on ice.
All-Terrain Options for Off-Roaders
For those who take their Explorer to campsites or down forest service roads, an All-Terrain (A/T) tire might be the better fit. These have deeper grooves and tougher sidewalls to resist punctures from sharp rocks.
Be aware that A/T tires can be noisier on the highway. If you value a silent cabin, look for “mild” all-terrain options that bridge the gap between highway comfort and off-road capability.
Essential Tools and Safety Steps for DIY Tire Service
If you plan on rotating your tires or swapping to a spare, you need the right tools. Working on a vehicle that weighs nearly 5,000 pounds requires a safety-first mindset.
- Floor Jack: Use a high-quality 3-ton floor jack. Never rely solely on the emergency scissor jack found in the trunk for routine maintenance.
- Jack Stands: Always place jack stands under the frame or designated lift points before putting any part of your body under the car.
- Torque Wrench: This is non-negotiable. The lug nuts on a 2017 Explorer must be tightened to exactly 100 lb-ft (135 Nm) to prevent wheel wobble or stud breakage.
- Pressure Gauge: Check your tire pressure monthly. For most 2017 Explorers, the recommended PSI is 35, but always check the sticker on your driver’s side door jamb.
When loosening lug nuts, do so while the tire is still touching the ground to prevent the wheel from spinning. Once the vehicle is lifted and secured on stands, you can remove the nuts completely.
Always tighten lug nuts in a star pattern. This ensures the wheel sits flush against the brake rotor and prevents warping of the brake components over time.
TPMS and Maintenance: Keeping Your Tires Healthy
Your 2017 Ford Explorer is equipped with a Tire Pressure Monitoring System (TPMS). This system uses sensors inside each wheel to alert you if the pressure drops significantly.
When you replace your tires, it is a “pro” tip to have the shop install new TPMS service kits. These include new rubber seals and valve cores to prevent slow leaks that often develop as the vehicle ages.
Regular tire rotations are the best way to maximize your investment. For an All-Wheel Drive (AWD) Explorer, Ford recommends rotating tires every 5,000 to 7,500 miles to ensure even tread wear across all four corners.
Checking for Uneven Wear
If you notice the inside edge of your tires wearing faster than the outside, your wheel alignment is likely out of spec. This often happens after hitting a deep pothole or sliding into a curb.
Uneven wear can also be caused by worn suspension bushings or struts. If a new set of tires feels “choppy” or makes a humming sound, have a licensed professional inspect your front-end components immediately.
Common Problems and Troubleshooting
Many owners report a “vibration” in the steering wheel at highway speeds. This is usually caused by an out-of-balance wheel rather than a mechanical failure in the steering system.
If the vibration occurs only when braking, the issue is likely warped brake rotors, not the tires. However, if the vibration is constant above 60 mph, a trip to the tire shop for a high-speed balance is necessary.
Another common issue is the “Low Tire Pressure” light staying on even after filling the tires. This often indicates a failing TPMS sensor battery or a sensor that needs to be “re-trained” to the vehicle’s computer.
When to Call a Professional
While DIYers can handle rotations and pressure checks, you should call a professional for tire mounting and balancing. These tasks require specialized machinery to ensure the tire sits perfectly on the rim without causing vibrations.
Additionally, if you see a bulge or “bubble” in the sidewall, do not drive the vehicle. This indicates internal structural damage, and the tire could blow out at any moment. Replace it with your spare immediately.
Frequently Asked Questions About 2017 Ford Explorer Tire Size
Can I put 20-inch wheels on an Explorer that came with 18-inch wheels?
Yes, you can upgrade to 20-inch wheels as long as you use the factory-recommended 255/50R20 tire size. However, keep in mind that your speedometer may be off by a very small percentage if the overall diameter changes slightly.
What is the spare tire size for a 2017 Ford Explorer?
Most 2017 Explorers come with a “compact” spare, typically sized at T165/80D17. This tire is for temporary use only and should not be driven faster than 50 mph or for long distances.
How long do tires typically last on a 2017 Ford Explorer?
On average, a set of high-quality all-season tires will last between 40,000 and 60,000 miles. This depends heavily on your driving habits, road conditions, and whether you stay diligent with rotations and alignments.
Does tire pressure change in the winter?
Yes, for every 10-degree drop in temperature, your tire pressure can drop by about 1 PSI. It is common for the TPMS light to trigger on the first cold morning of the year; simply top them off to the pressure listed on your door placard.
Final Thoughts on Your Explorer’s Rubber
Maintaining the correct 2017 ford explorer tire size is about more than just following a manual; it is about ensuring your vehicle performs safely when you need it most. Whether you are navigating a rain-slicked highway or a muddy trail, your tires are the only point of contact between you and the ground.
Take the time to check your tread depth using the “penny test” and keep a close eye on your tire pressure. These small steps prevent expensive repairs and keep your Explorer running smoothly for years to come.
By understanding your trim’s specific needs and choosing a tire that matches your environment, you are taking charge of your vehicle’s health. Stay safe, keep those lug nuts tight, and enjoy the road ahead!
