Let’s dive into the specifics of the ford explorer tire size and what those numbers on the sidewall actually mean for your vehicle.
Decoding the Ford Explorer Tire Size by Generation
The Ford Explorer has evolved significantly since its debut in 1991. As the vehicle grew in size and power, so did the wheels and tires. Understanding your specific generation is the first step in identifying the correct ford explorer tire size for your needs.
First and Second Generations (1991–2001)
Early Explorers were built on truck-based platforms, emphasizing utility and ruggedness. Most of these models rolled off the assembly line with 15-inch or 16-inch wheels. The most common factory size for these vintage rigs is 235/75R15 or 255/70R16.
If you own one of these classics, you likely use it for light trails or as a reliable workhorse. When replacing these tires, prioritize all-terrain patterns if you spend time on gravel. For strictly city driving, a standard highway-terrain tire will offer a much quieter ride and better fuel economy.
Third and Fourth Generations (2002–2010)
With the introduction of independent rear suspension, the Explorer became more refined. Tire sizes shifted toward 16, 17, and even 18-inch options on higher trims like the Eddie Bauer or Limited editions. Common sizes include 235/70R16, 245/65R17, and 235/65R18.
These generations are prone to wheel bearing wear if you install tires that are too heavy or have an aggressive offset. Always stick close to the factory weight specifications to preserve your suspension components. If you are a DIYer, check your door jamb placard for the exact pressure requirements for these specific sizes.
Fifth Generation (2011–2019)
The move to a unibody platform changed the Ford Explorer into a modern crossover. This era saw a massive jump in wheel diameters, with 18-inch wheels becoming the standard and 20-inch wheels appearing on the Sport and Platinum trims. You will typically find 245/60R18 or 255/50R20 sizes here.
The 20-inch setups look fantastic but offer a thinner sidewall. This means you will feel more bumps in the road compared to the 18-inch versions. If you prioritize comfort, consider touring tires that feature specialized rubber compounds designed to soak up road vibrations.
Sixth Generation (2020–Present)
The current generation returned to a rear-wheel-drive biased platform, bringing even larger fitments. Base models start with 18-inch wheels, while the ST and Platinum trims often sport 21-inch wheels. Common sizes include 255/65R18, 255/55R20, and the massive 275/45R21.
For the ST performance models, tire selection is critical for maintaining grip during spirited driving. You should look for ultra-high performance (UHP) all-season tires. These provide the lateral grip needed for a heavy SUV with over 400 horsepower while still being safe in the rain.
Choosing the Right Ford Explorer Tire Size for Your Trim
Not every Explorer is built for the same purpose, and your trim level dictates which ford explorer tire size is most appropriate. A Timberline owner has very different needs than someone driving an XLT around the suburbs. Matching the tire to the trim ensures you aren’t leaving performance on the table.
The Timberline trim, for example, comes factory-equipped with 265/65R18 all-terrain tires. This size provides a taller sidewall, which is excellent for airing down when driving on soft sand or rocky trails. The extra rubber acts as a secondary cushion, protecting your rims from trail damage.
On the other hand, the Limited and Platinum trims focus on luxury. These often use 20-inch or 21-inch wheels with a lower profile. While these sizes improve steering response on the highway, they are more susceptible to pothole damage. If you live in an area with poorly maintained roads, you might actually benefit from “downsizing” to an 18-inch wheel with a thicker tire.
When selecting a new set, always check the load index. The Explorer is a heavy vehicle, especially when loaded with seven passengers and gear. Ensure your new tires meet or exceed the factory load rating (usually 103 to 107 for modern models) to prevent premature tire failure or blowouts.
How to Read the Sidewall of Your Tires
To the untrained eye, the numbers on a tire sidewall look like a secret code. However, understanding this string of digits is the only way to ensure you get the right ford explorer tire size. Let’s break down a common size like 255/60R18.
- 255: This is the width of the tire in millimeters from sidewall to sidewall.
- 60: This is the aspect ratio. It means the height of the sidewall is 60% of the width.
- R: This stands for Radial construction, which is standard for almost all modern passenger vehicles.
- 18: This is the diameter of the wheel in inches that the tire is designed to fit.
Beyond the dimensions, you will also see a speed rating (like H, V, or W). For a Ford Explorer, an H-rating (up to 130 mph) is usually sufficient for standard driving. However, if you drive an ST model, you may require a V or W rating to handle the vehicle’s higher top-speed capabilities safely.
Don’t ignore the DOT code either. This four-digit number tells you when the tire was manufactured. For example, “1223” means the tire was made in the 12th week of 2023. Even if a tire has plenty of tread, the rubber compounds break down after six to ten years, making them unsafe for highway use.
Modifying Your Tire Size for Off-Road Performance
Many enthusiasts want to give their SUV a more aggressive stance by increasing the ford explorer tire size beyond factory limits. This is a popular mod for the Timberline or older 4WD models. However, “sizing up” requires careful planning to avoid mechanical issues.
A common upgrade for the newer Explorer is moving to a 265/70R18 or even a 33-inch tire. While this adds ground clearance, it can lead to rubbing against the wheel liners or suspension components during tight turns. You may need a 2-inch leveling kit or lift kit to clear these larger diameters properly.
Remember that larger tires are heavier. This added unsprung weight makes your brakes work harder and can decrease your fuel economy by 1-3 miles per gallon. It also affects your speedometer; a larger tire travels further in one revolution, meaning your speedometer will read slower than your actual speed.
If you plan to do serious off-roading, look for tires with reinforced sidewalls (labeled as “E-load” or “10-ply”). These are much more resistant to punctures from sharp rocks and sticks. Just be aware that these tires provide a much stiffer ride on the pavement, which might not be ideal for a family road trip.
Essential Tools and Safety Steps for Tire Maintenance
Maintaining your ford explorer tire size investment requires more than just checking the air pressure occasionally. If you are a DIY mechanic, having the right tools in your garage will save you money and keep your vehicle safe on the road.
Every owner should own a high-quality digital pressure gauge and a calibrated torque wrench. When you rotate your tires or swap to a winter set, you must tighten the lug nuts to the specific factory torque. For most modern Explorers, this is roughly 150 lb-ft, but you should always verify this in your owner’s manual.
- Loosen: Break the lug nuts loose while the vehicle is still on the ground.
- Lift: Use a floor jack on the designated frame lift points. Never rely solely on a jack; always use jack stands for safety.
- Inspect: While the wheel is off, check your brake pads and look for any leaking shocks or struts.
- Rotate: Move the tires according to the pattern in your manual (usually front-to-back or a cross pattern).
- Torque: Lower the vehicle and tighten the lug nuts in a star pattern to ensure even pressure on the brake rotor.
If you notice uneven tread wear—such as the inside of the tire wearing faster than the outside—your alignment is likely off. Getting a professional alignment after installing a new ford explorer tire size is highly recommended. It ensures your tires point straight and prevents you from “scrubbing” away expensive tread prematurely.
Seasonal Considerations: Winter vs. All-Season
While many Explorers come with all-season tires, they aren’t always the best choice for every climate. If you live in a region with heavy snowfall, the standard ford explorer tire size in an all-season compound may lose grip when temperatures drop below 45 degrees Fahrenheit.
Winter tires are made from a softer rubber that stays flexible in the cold. They also feature sipes—tiny slits in the tread blocks that bite into ice and packed snow. For many owners, having a dedicated set of winter tires on a second set of cheap steel wheels is a smart long-term investment.
If you don’t want to swap tires twice a year, consider “All-Weather” tires. These are a relatively new category that carries the Three-Peak Mountain Snowflake (3PMSF) rating. They offer better snow traction than a standard all-season but can still be driven safely during the hot summer months.
Frequently Asked Questions About 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, provided you choose the correct ford explorer tire size to maintain the overall outer diameter. For example, if you move from a 245/60R18 to a 255/50R20, the total height remains nearly identical, which keeps your speedometer accurate.
What is the correct tire pressure for a Ford Explorer?
While it varies by year and load, most modern Explorers require between 33 and 35 PSI (pounds per square inch). Do not use the “Max Pressure” listed on the tire sidewall; instead, always follow the recommendation found on the white and yellow sticker inside the driver’s side door jamb.
How often should I rotate the tires on my Explorer?
You should rotate your tires every 5,000 to 7,500 miles. Since the Explorer is available in RWD, FWD, and AWD configurations, the wear patterns can vary. Regular rotation ensures that all four tires wear down at the same rate, extending the life of the set.
Will larger tires void my Ford warranty?
Generally, installing a slightly larger ford explorer tire size will not void your entire warranty. However, if the larger tires cause damage to the wheel bearings, suspension, or drivetrain, the dealer may refuse to cover those specific repairs. Always consult with your service advisor before making drastic changes.
Do I need to recalibrate my TPMS after a tire change?
Most modern Ford vehicles will automatically recognize the Tire Pressure Monitoring System (TPMS) sensors after a few miles of driving. However, if you are using a new set of wheels with new sensors, you may need a simple TPMS reset tool to “pair” them with the vehicle’s computer.
Summary and Final Thoughts
Selecting the right ford explorer tire size is one of the most impactful maintenance decisions you can make. By sticking to factory dimensions, you ensure that your vehicle performs exactly as the engineers intended. If you choose to deviate for off-road style or performance, doing so with an understanding of aspect ratios and load ratings will keep you safe.
Remember to check your tread depth regularly using the “penny test” and keep an eye on your tire pressures as the seasons change. A well-maintained set of tires not only improves your safety but also saves you money at the fuel pump. Whether you are tackling a muddy trail or a rainy commute, the right rubber makes all the difference.
Take the time to inspect your sidewalls for cracks or bulges, and never ignore a TPMS warning light. Your Ford Explorer is a capable, versatile machine that deserves high-quality tires to match its potential. Stay safe, stay informed, and enjoy the road ahead!
