Understanding Your 2020 Ford Explorer Tire Size Options
The 2020 model year marked a massive shift for the Explorer, moving to a rear-wheel-drive biased platform. This change affected how the vehicle wears through rubber and what sizes work best for its new stance. Depending on whether you have the Base, XLT, Limited, ST, or Platinum trim, your wheel diameter and width will vary significantly.
Most 2020 Explorers come equipped with one of three primary wheel sizes: 18-inch, 20-inch, or 21-inch. Each size offers a different balance of ride comfort, aesthetic appeal, and cornering stability. A larger sidewall on an 18-inch tire generally provides a softer ride, while the low-profile 21-inch tires on the ST trim offer sharper handling.
The 18-Inch Factory Standard
If you own the Base or XLT trim, your standard 2020 ford explorer tire size is likely 255/65R18. This size is excellent for daily commuting because the taller sidewall absorbs potholes and road imperfections effectively. It is a common size, meaning you will have plenty of affordable options when it comes time to replace them.
The 20-Inch Mid-Range Choice
The Limited trim and upgraded XLT models typically move up to a 255/55R20 setup. This size strikes a middle ground, offering a more modern, filled-out look in the wheel well without sacrificing too much comfort. These tires provide a bit more stability during highway lane changes due to the slightly shorter sidewall.
The 21-Inch Performance Fitment
For those driving the high-output ST or the luxury-focused Platinum, the standard fitment is 275/45R21. This is a wide, aggressive tire designed to put more power to the ground. While these look incredible, keep in mind that 21-inch tires are often more expensive and can offer a firmer ride over bumps.
Why Trim Levels Dictate Your Tire Choice
Ford engineers tuned the suspension of each Explorer trim to work specifically with certain wheel and tire combinations. For example, the ST trim features stiffer dampers and larger brakes. If you were to downsize the wheels on an ST, you might run into clearance issues with the brake calipers.
When shopping for replacements, always verify your trim level and current wheel diameter. You can find this information on the tire placard located inside the driver-side door jamb. This sticker lists the original equipment size and the recommended cold inflation pressure for your specific vehicle.
- Base & XLT: Typically use 255/65R18 for maximum comfort.
- Limited: Standardizes the 255/55R20 for a premium highway feel.
- ST & Platinum: Utilize 275/45R21 for maximum grip and performance.
If you are a DIY mechanic looking to swap wheels between trims, be aware of the offset. The offset determines how far the wheel sits inside or outside the fender. Using the wrong offset can cause the tire to rub against the inner liner or suspension components during tight turns.
Upgrading for Off-Road and All-Terrain Performance
Many owners want to give their SUV a more rugged look or better capability on forest service roads. While the 2020 Explorer is a unibody SUV, it is surprisingly capable with the right tread pattern. Upgrading from a standard Highway Terrain (HT) tire to an All-Terrain (AT) tire can transform your weekend adventures.
For those with 18-inch wheels, you have the best selection for off-road rubber. Tires like the Falken Wildpeak A/T3W or the BFGoodrich All-Terrain T/A KO2 are popular choices. These tires feature reinforced sidewalls and aggressive lugs to bite into mud, gravel, and snow.
If you have 20-inch or 21-inch wheels, finding aggressive off-road tires is more challenging and expensive. Many enthusiasts choose to “downsize” their wheels to 18 inches to gain more sidewall. This extra rubber acts as a secondary cushion when airing down for traction on soft surfaces like sand or loose dirt.
Considering All-Weather vs. All-Season
If you live in a region with heavy snowfall, look for tires with the Three-Peak Mountain Snowflake (3PMSF) symbol. While “All-Season” tires are fine for light rain and dry roads, “All-Weather” tires provide significantly better traction in freezing temperatures. This is a critical safety upgrade for any 2020 ford explorer tire size you choose.
Tire Width and Fuel Economy
Keep in mind that wider tires, like the 275mm width found on the ST, create more rolling resistance. If you are focused on maximizing your MPG, sticking to the 255mm width is usually the better choice. Narrower tires also tend to perform better in deep snow as they “cut” through to the pavement rather than floating on top.
Essential Tools and Maintenance for Explorer Tires
Maintaining your tires is just as important as choosing the right size. To do this properly at home, you need a few basic tools. A high-quality digital pressure gauge is essential, as the TPMS (Tire Pressure Monitoring System) in the dash can sometimes be off by a few PSI.
When rotating your tires, which you should do every 5,000 to 7,500 miles, you will need a torque wrench. Ford specifies a high torque value of 150 lb-ft for the lug nuts on the 2020 Explorer. Using a simple tire iron isn’t enough; you need the precision of a torque wrench to prevent warped brake rotors.
- Floor Jack: Ensure it is rated for at least 3 tons to handle the Explorer’s weight safely.
- Jack Stands: Never work under a vehicle supported only by a hydraulic jack.
- Tread Depth Gauge: Use this to monitor wear patterns and know exactly when to replace your tires.
- TPMS Reset Tool: Useful if you swap between winter and summer wheel sets yourself.
Always inspect your tires for dry rot or “checking” in the sidewalls, especially if the vehicle sits outside in the sun. If you see small cracks developing, it is time to start shopping for replacements, regardless of how much tread is left. Safety should always come before trying to squeeze a few more miles out of old rubber.
Common Problems and Troubleshooting Tips
Even with the perfect 2020 ford explorer tire size, you might encounter issues like vibrations or uneven wear. If you feel a shaking in the steering wheel at highway speeds, your wheels are likely out of balance. A professional shop can use a road-force balancer to ensure the weight is distributed perfectly around the rim.
Uneven wear on the inside or outside edges of the tread usually points to an alignment issue. The 2020 Explorer’s multi-link rear suspension is adjustable, but it can be knocked out of spec by hitting a large pothole. Getting an alignment once a year can easily double the lifespan of your tires.
If your TPMS light stays on even after filling the tires, you might have a failing sensor battery. These sensors typically last 5 to 7 years. Since the 2020 models are getting older, it is common for these batteries to begin failing. Most tire shops can replace the sensor during your next tire change for a small fee.
Dealing with Road Noise
Larger tires, especially those with aggressive tread, can produce a “hum” or “drone” at high speeds. If quietness is your priority, look for tires labeled as “Low Rolling Resistance” or those with noise-canceling tread technology. Brands like Michelin and Continental often prioritize a quiet cabin experience in their SUV lineups.
Safety First: Load Index and Speed Ratings
When looking at the sidewall of your tire, you will see a string of numbers followed by a letter, such as 107H or 110V. The number is the load index, representing how much weight the tire can safely carry. The letter is the speed rating, indicating the maximum speed the tire can sustain without failing.
For a heavy SUV like the Explorer, you must never install a tire with a lower load index than the factory recommendation. Doing so can lead to a catastrophic blowout due to excessive heat buildup. Most 2020 Explorers require a load index of at least 107. Always check your manual to be certain.
Speed ratings are also vital, especially for the ST trim. Since the ST is capable of high speeds, it requires a “V” or “W” rated tire. Installing a “T” rated tire (common on smaller cars) on an Explorer ST could result in the tire deforming or failing under high-speed stress. Always match or exceed the factory speed rating for maximum safety.
Frequently Asked Questions About 2020 Ford Explorer Tire Size
Can I put 20-inch wheels on my Explorer XLT that came with 18s?
Yes, you can absolutely upgrade to 20-inch wheels. However, you must ensure the new 2020 ford explorer tire size maintains the same overall diameter as the original. Using a 255/55R20 tire will keep your speedometer accurate and ensure your safety systems like ABS and traction control function correctly.
What is the correct tire pressure for a 2020 Ford Explorer?
For most trims, the recommended cold tire pressure is 33 to 35 PSI. However, this can vary if you are towing a heavy trailer or carrying a full load of passengers. Always refer to the sticker on your driver’s side door jamb for the most accurate number for your specific vehicle configuration.
How long should the factory tires last on a 2020 Explorer?
On average, the original equipment (OE) tires last between 30,000 and 50,000 miles. The performance-oriented tires on the ST trim often wear out faster due to their softer rubber compound. Regular rotations and maintaining proper alignment are the best ways to extend the life of your rubber.
Is it okay to mix different brands of tires on my Explorer?
It is strongly recommended to keep all four tires identical, especially on Intelligent 4WD models. Differences in tread depth or grip levels between brands can put unnecessary strain on the transfer case and differentials. If you must replace only two tires, ensure they are the same brand and model as the others and place the new ones on the rear axle.
Do I need special tires if I plan on towing?
If you frequently tow a boat or camper, consider a tire with an “Extra Load” (XL) rating. These tires have reinforced internal structures that handle the increased tongue weight of a trailer much better than standard tires. This prevents the sidewalls from flexing excessively, which improves stability while towing on the highway.
Conclusion: Keeping Your Explorer Grounded
Selecting the right tires for your SUV is one of the most impactful maintenance decisions you can make. From the smooth-riding 18-inch setups to the high-performance 21-inch options, the right fitment ensures your vehicle performs exactly as the engineers intended. Remember that your tires are the only part of your vehicle that actually touches the road.
Take the time to check your tread depth regularly and keep those pressures set to factory specs. Whether you are a DIY mechanic or a casual owner, staying informed about your vehicle’s needs keeps you safe and saves you money in the long run. Invest in quality rubber, and your Explorer will reward you with years of reliable service.
Stay safe on the road, keep an eye on your alignment, and enjoy the drive!
