Finding the correct ford explorer xlt tire size depends largely on your vehicle’s generation and optional wheel packages, typically ranging from 18-inch to 20-inch diameters. This guide provides the exact factory specifications, explains how to decode sidewall markings, and offers expert advice on choosing the best rubber for towing, commuting, or off-road adventures.
You probably know that your Ford Explorer XLT is the workhorse of the family, handling everything from school runs to weekend camping trips. But you might have noticed that the ride feels a bit stiffer lately or the traction in the rain isn’t what it used to be.
Finding the right ford explorer xlt tire size is the first step toward restoring that factory-fresh handling and ensuring your family stays safe on the highway. Choosing the wrong size or load rating can lead to poor fuel economy, speedometer errors, and even mechanical strain on your drivetrain.
In this guide, I will break down the specific fitments for every major Explorer generation, explain the technical jargon on your tire’s sidewall, and help you decide when it is time to stick with OEM specs or upgrade for the trail. Let’s get your SUV back to peak performance with the right set of shoes.
Understanding Your Ford Explorer XLT Tire Size and Factory Specs
The Ford Explorer XLT has evolved significantly over the years, transitioning from a body-on-frame SUV to a unibody crossover. This evolution means that the ford explorer xlt tire size has changed to accommodate different suspension geometries and weight distributions.
For the most recent 6th Generation (2020–Present), the XLT trim typically comes standard with 18-inch wheels, but many units are equipped with the optional 20-inch Premium Painted Aluminum wheels. The standard size for the 18-inch rims is 255/65R18, while the 20-inch upgrade uses a 255/55R20 fitment.
If you own a 5th Generation model (2011–2019), you are likely looking at a 245/60R18 as the base fitment. Some Sport Appearance packages on the XLT trim during these years bumped the size up to a 255/50R20, which offers a lower profile and more responsive handling on paved roads.
Common Sizes by Model Year
- 2020–2024 Models: 255/65R18 (Standard) or 255/55R20 (Optional).
- 2011–2019 Models: 245/60R18 (Standard) or 255/50R20 (Optional).
- 2006–2010 Models: 235/70R16 or 245/65R17.
Always verify your specific vehicle’s requirements by checking the tire information placard. You can find this sticker on the driver’s side door jamb, which lists the original equipment size and the recommended cold inflation pressure.
Decoding the Sidewall: What Those Numbers Mean for Your SUV
When you look at the side of your tire, the string of numbers can look like a secret code. Understanding these metrics is vital when shopping for a new ford explorer xlt tire size because it impacts more than just the fit.
Take the common 255/65R18 size as an example. The 255 represents the section width in millimeters from sidewall to sidewall. A wider tire generally provides more grip but can slightly decrease fuel efficiency due to increased rolling resistance.
The 65 is the aspect ratio, which tells you the height of the sidewall as a percentage of the width. A higher number means a taller sidewall, which acts as extra cushioning against potholes—a favorite feature for those of us who frequent gravel roads or poorly maintained city streets.
Load Index and Speed Ratings
The letter and number following the size (e.g., 111H) are arguably the most important for safety. The Load Index (111) indicates how much weight each tire can support. Since the Explorer is a heavy vehicle often used for hauling, never install a tire with a lower load index than the factory recommendation.
The Speed Rating (H, V, or T) indicates the maximum speed the tire can safely maintain. For an XLT, an H-rating (up to 130 mph) is standard. While you likely won’t be hitting those speeds, the rating also relates to how well the tire dissipates heat during long summer highway hauls.
Upgrading Your Wheels: Plus-Sizing and Off-Road Fitment
Many owners want to move away from the stock ford explorer xlt tire size to achieve a more aggressive look or better off-road capability. This is often referred to as plus-sizing when you increase the wheel diameter or “upsizing” when you keep the wheel but increase the tire height.
If you are a weekend warrior hitting light trails, you might consider a 265/60R18. This is slightly wider and taller than the stock 245/60R18 used on older XLTs. It provides a bit more ground clearance and a larger footprint for traction in mud or sand.
However, be cautious of rubbing issues. When you increase the tire diameter significantly, the rubber may contact the inner fender liner or the suspension strut tower during sharp turns. For the 6th Gen Explorer, you can usually go up one size without a lift kit, but anything larger requires a leveling kit.
The Impact on Speedometer Accuracy
Changing the overall diameter of your tire affects your speedometer. If you install a taller tire, your speedometer will actually read slower than your true speed. This happens because a larger tire travels further with each revolution.
Modern Explorers allow for some computer recalibration through tools like FORScan or dealership software. If you jump from an 18-inch to a significantly larger all-terrain setup, recalibrating the PCM (Powertrain Control Module) ensures your shift points and ABS remain optimized.
Maintenance Essentials: Pressure, Rotation, and Torque Specs
Once you have the correct ford explorer xlt tire size installed, maintenance is what determines how long that investment lasts. The Explorer is a heavy, front-heavy vehicle (even in the RWD-based 2020+ models), which leads to uneven wear if neglected. Tire pressure is the most frequent maintenance task you should perform. For most XLT models, the recommended pressure is 33 to 35 PSI. Running them too low increases heat and risks a blowout, while running them too high causes the center of the tread to wear out prematurely.
I recommend a tire rotation every 5,000 to 7,500 miles. For AWD and 4WD Explorers, a “rearward cross” pattern is typically best. This involves moving the front tires to the rear (staying on the same side) and moving the rear tires to the front but switching sides.
Lug Nut Torque and Safety
When you are swapping your own wheels, perhaps during a seasonal change, using a torque wrench is non-negotiable. Ford specifies a torque of 150 lb-ft (204 Nm) for most modern Explorer lug nuts.
Under-tightening can lead to the wheel loosening while driving, while over-tightening can stretch the studs or warp the brake rotors. Always tighten in a star pattern to ensure the wheel seats evenly against the hub assembly.
Choosing the Best Tires for Different Driving Conditions
When searching for the correct ford explorer xlt tire size, you also need to choose the right type of tire for your climate. A tire that excels in the Arizona heat will likely fail you during a Michigan blizzard.
For most owners, an All-Season tire is the go-to choice. These are designed to provide a quiet ride and good wet/dry traction. Look for models like the Michelin Defender LTX M/S if you prioritize longevity and highway comfort.
If you live in an area with heavy snow, look for the Three-Peak Mountain Snowflake (3PMSF) symbol. This indicates the tire has been tested for severe snow performance. All-terrain tires like the BFGoodrich All-Terrain T/A KO2 are popular for XLT owners who want a rugged look without sacrificing too much street drivability.
Towing and Payload Considerations
The Explorer XLT is often rated to tow up to 5,300 lbs when properly equipped. If you frequently pull a boat or a travel trailer, the sidewall stiffness of your tires matters. Look for tires with a reinforced sidewall or an “XL” (Extra Load) rating.
Softer tires designed purely for comfort may feel “squishy” or unstable when a heavy trailer is attached. Choosing a tire with a higher load range provides a more stable towing platform and reduces the swaying sensation caused by sidewall flex.
Essential Tools for a DIY Tire Change on Your Explorer
If you plan on managing your ford explorer xlt tire size needs at home, you need the right gear. The emergency jack included with the vehicle is for roadside emergencies only; it is not stable enough for routine maintenance.
Invest in a 3-ton floor jack and a pair of high-quality jack stands. The Explorer is a heavy SUV, and you should never put any part of your body under the vehicle while it is supported only by a hydraulic jack.
- 19mm or 21mm Deep Socket: Most factory Explorer lugs use these sizes.
- Breaker Bar: To loosen stubborn lug nuts before lifting the car.
- Calibrated Torque Wrench: Essential for the final 150 lb-ft tightening.
- Tire Pressure Gauge: A high-quality digital or dial gauge is more accurate than the gas station versions.
- Tread Depth Tool: To monitor wear and know exactly when it is time to shop for replacements.
Keep a small portable air compressor in your trunk. These are invaluable for adjusting pressures if you air down for a beach drive or if you wake up to a low-pressure warning on a freezing morning.
Frequently Asked Questions About ford explorer xlt tire size
Can I put 20-inch wheels on an XLT that came with 18-inch wheels?
Yes, you can upgrade to 20-inch wheels as long as you use the correct ford explorer xlt tire size for that rim (typically 255/55R20). Ensure the new wheels have the correct bolt pattern (5×114.3mm) and offset to avoid hitting the brake calipers.
What happens if I use a tire with a lower load rating?
Using a lower load rating is dangerous. The tire may not be able to support the weight of the SUV, especially when loaded with passengers or cargo. This can lead to catastrophic tire failure or a blowout at highway speeds.
How often should I check my tire pressure?
You should check your tire pressure at least once a month and before any long road trip. Remember that for every 10-degree drop in temperature, your tires can lose about 1 PSI of pressure.
Will larger tires void my Ford warranty?
Generally, simply changing tire sizes won’t void your entire warranty. However, if the larger tires cause premature wear on wheel bearings, CV axles, or the transmission, Ford may deny warranty claims related to those specific components.
Final Thoughts on Maintaining Your Ford Explorer
Selecting the right ford explorer xlt tire size is one of the most impactful maintenance decisions you can make. It dictates how your vehicle handles emergency maneuvers, how much noise enters the cabin, and how much you spend at the pump every week.
Take the time to look at your door jamb, inspect your current tread depth, and consider your typical driving environment. Whether you choose a comfort-oriented highway tire or a rugged all-terrain set, staying within the recommended load and speed parameters is key to a long-lasting SUV.
Keep those lug nuts torqued, your pressures checked, and your rotations on schedule. Your Explorer is built to go the distance—make sure its tires are too. Stay safe and stay comfortable!
