The Standard 2019 ford explorer tire size by Trim Level
Ford designed the 2019 Explorer with several wheel options to match different performance needs and aesthetic goals. Identifying your trim level is the fastest way to find your factory tire dimensions and ensure a proper fit.
The Base and XLT trims typically come equipped with 18-inch wheels from the factory. These models generally use a 245/60R18 tire, which offers a comfortable ride quality and balanced fuel economy for daily driving.
Stepping up to the Limited, Sport, or Platinum trims introduces larger 20-inch wheels as standard equipment. These higher-end models usually require a 255/50R20 tire to accommodate the larger rim diameter and provide sharper handling.
It is also worth noting that some XLT models may have been upgraded with the 20-inch wheel package. Always check the tire placard located on the driver-side door jamb to verify the original equipment size for your specific VIN.
For those who have the Police Interceptor Utility version of the Explorer, the sizing is slightly different. These heavy-duty models often use a 245/55R18 setup designed for high-speed stability and heat management during pursuit driving.
Understanding the Numbers: Decoding Your Sidewall
Understanding the numbers on your tire is crucial for any DIY mechanic or car owner looking to buy replacements. Let’s break down what these alphanumeric codes actually mean for your vehicle’s performance.
The first number, such as 255, represents the width of the tire in millimeters from sidewall to sidewall. A wider tire provides a larger contact patch with the road, which can improve braking and cornering grip.
The second number, like 50 or 60, is the aspect ratio, which indicates the height of the sidewall. This number is a percentage of the width; a lower aspect ratio means a shorter, stiffer sidewall for better handling.
What the “R” and Rim Size Mean
The “R” in the sequence stands for radial construction, which is the industry standard for almost all modern passenger vehicles. Radial tires offer better heat dissipation and a much smoother ride than older bias-ply designs.
The final number, 18 or 20, is the wheel diameter measured in inches. It is vital to match this exactly to your 2019 ford explorer tire size requirements, as you cannot fit an 18-inch tire on a 20-inch rim.
Attempting to mount the wrong diameter tire is physically impossible and extremely dangerous. Always double-check your rim size before placing an order with an online retailer or local tire shop.
Load Index and Speed Ratings: Why They Matter for SUVs
Beyond the physical dimensions, you must consider the load index and speed rating when selecting new rubber. These factors determine how much weight the tire can carry and how fast it can safely travel under load.
For a heavy SUV like the Explorer, you typically want a load index of at least 105 or 107. This ensures the tires can support the vehicle’s curb weight plus a full load of passengers and heavy cargo.
The speed rating is usually designated by a letter such as H, V, or W at the end of the size string. For most 2019 models, an H-rated (up to 130 mph) or V-rated (up to 149 mph) tire is the factory standard.
Never “downgrade” your speed rating or load index below the manufacturer’s recommendations. Doing so can lead to excessive heat buildup and potential tire failure, especially during long summer highway hauls.
If you plan on towing a boat or a travel trailer, the load index becomes even more critical. Ensure your tires are rated for the additional tongue weight to prevent sidewall flexing and unstable swaying on the road.
Upgrading for the Trail: All-Terrain Options and Clearance
Many Explorer owners enjoy light off-roading or live in areas with heavy snow and mud. In these cases, a standard highway-terrain tire might not provide the traction you need to stay moving.
If you are looking to upgrade, consider an All-Terrain (A/T) tire with an aggressive tread pattern. These tires feature deeper grooves and tougher rubber compounds to resist punctures from sharp rocks or trail debris.
Keep in mind that switching to a more aggressive 2019 ford explorer tire size or tread pattern can increase road noise. You may also notice a slight drop in fuel economy due to the increased rolling resistance of the knobby tread.
For those living in the “Rust Belt” or mountainous regions, look for tires with the Three-Peak Mountain Snowflake (3PMSF) symbol. This rating indicates the tire meets specific snow traction requirements and performs better than standard M+S tires.
Checking for Wheel Well Clearance
If you decide to go slightly larger than the factory size for a beefier look, check for clearance issues. Rubbing against the inner fender liner or suspension components can cause rapid tire wear and dangerous blowouts.
As a general rule, try to stay within 3% of the original overall diameter to avoid recalibrating your speedometer. Going larger than this often requires a leveling kit to ensure the tires do not rub during full-lock turns.
Check the distance between the tire and the upper control arm or the strut tower. If the clearance is less than half an inch, you may need wheel spacers or a different offset wheel to prevent contact.
Essential Tools and Steps for a DIY Tire Rotation
Rotating your tires every 5,000 to 7,500 miles is the best way to extend their lifespan. For a DIY mechanic, this is a straightforward task that requires only a few basic tools and about an hour of time.
You will need a high-quality floor jack, at least two jack stands, and a torque wrench. Never work on a vehicle supported only by a hydraulic jack; always use stands for safety.
- Loosen the lug nuts while the vehicle is still on the ground using a 19mm or 21mm socket.
- Lift the vehicle and secure it on jack stands at the factory-designated lift points.
- Move the front tires straight back to the rear and move the rear tires to the opposite front corners.
- Hand-tighten the lug nuts before lowering the vehicle to ensure they are seated correctly.
- Lower the SUV and use a torque wrench to tighten the lug nuts to 100 lb-ft in a star pattern.
Using a torque wrench is non-negotiable for the Explorer. Over-tightening can warp your brake rotors, while under-tightening can lead to a wheel coming loose while you are driving.
While the wheels are off, take a moment to inspect your brake pads and suspension bushings. It is much easier to spot a leaking strut or a worn-out ball joint when the tire is out of the way.
Tire Pressure and Maintenance for Longevity
Proper inflation is the single most important factor in tire longevity and vehicle safety. Neglecting your air pressure can lead to uneven wear, poor handling, and even catastrophic tire failure.
Check your tire pressure at least once a month using a reliable digital gauge. The recommended PSI for a 2019 Explorer is typically 35 PSI, but always verify this on your specific door jamb sticker.
The Tire Pressure Monitoring System (TPMS) in your Ford is a great safety net, but it only alerts you when pressure is significantly low. Manually checking ensures you catch small leaks before they become major problems.
Temperature changes can cause your tire pressure to fluctuate significantly. For every 10-degree drop in outside temperature, your tires can lose about one pound of pressure, making winter checks vital.
Identifying Common Wear Patterns
Inspecting your tread patterns can tell you a lot about your vehicle’s health. Wear on both outer edges usually indicates under-inflation, while wear in the center suggests over-inflation.
If you see “cupping” or diagonal scalloping across the tread, your shocks or struts might be worn out. This causes the tire to bounce down the road, creating uneven spots that lead to noise and vibration.
Wear on only one edge of the tire is a classic sign of poor wheel alignment. If you notice this, take your Explorer to a professional shop to have the camber and toe settings adjusted immediately.
Frequently Asked Questions About 2019 ford explorer tire size
Can I put 18-inch wheels on an Explorer that came with 20s?
Yes, you can usually downsize to 18-inch wheels as long as they are designed to clear the brake calipers. Many owners do this for winter tire setups because 18-inch tires are often cheaper and provide a softer ride on icy roads.
What is the correct lug nut torque for a 2019 Ford Explorer?
The factory specification for the 2019 Explorer is 100 lb-ft (135 Nm). Always use a calibrated torque wrench and tighten in a “star” or “criss-cross” pattern to ensure even pressure across the wheel hub.
Does the 2019 Ford Explorer have a full-size spare tire?
Most 2019 Explorer models come with a compact temporary spare tire located under the rear cargo floor. If you frequently travel off-road or in remote areas, you might consider purchasing a matching full-size wheel and tire for peace of mind.
How do I reset the TPMS light after adding air?
In most cases, the TPMS light will turn off automatically after you drive the vehicle for a few miles at speeds above 20 mph. If it stays on, ensure all tires—including the spare if equipped with a sensor—are at the correct pressure.
How long should the factory tires last on a 2019 Explorer?
Most factory-installed tires are designed to last between 30,000 and 50,000 miles. However, this depends heavily on your driving habits, road conditions, and how strictly you follow a rotation schedule.
Final Thoughts on Choosing the Right Rubber
Choosing the right 2019 ford explorer tire size is about more than just matching numbers; it is about protecting your investment and your passengers. By sticking to the manufacturer’s specifications, you ensure your SUV performs exactly as the engineers intended.
Whether you choose a highway-focused Michelin for quiet commutes or a rugged Goodyear for weekend trails, prioritize quality and safety ratings. A high-quality set of tires is the only thing connecting your heavy SUV to the pavement, so it is never the place to cut corners.
Keep your air pressure checked, rotate your tires regularly, and stay mindful of tread depth. With the right set of tires and a little bit of DIY care, your Ford Explorer will continue to provide a safe and comfortable ride for many miles to come. Stay safe and enjoy the open road!
