In this guide, we will break down the specific factory specifications for every trim level and explore how different rubber compounds affect your ride quality. Whether you are a DIY mechanic or a weekend adventurer, understanding the 2019 ford expedition tire size ensures your SUV performs exactly as the engineers intended.
We will also cover the essential tools you need for a tire swap and how to identify when your current set has reached the end of its service life. Let’s dive into the technical details so you can get back on the road with confidence.
Decoding the 2019 ford expedition tire size by Trim Level
Ford designed the 2019 Expedition to be a versatile powerhouse, which means the wheel and tire combinations vary significantly between the XLT, Limited, and Platinum trims. The base XLT often comes equipped with 18-inch wheels, providing a thicker sidewall that is ideal for absorbing bumps and navigating light off-road trails.
If you own the Limited trim, your 2019 ford expedition tire size likely jumps to a 20-inch diameter, which offers a balance between aesthetic appeal and towing stability. The Platinum trim typically features massive 22-inch wheels, which look incredible but require a lower-profile tire that prioritizes on-road handling over off-road cushioning.
It is vital to check your driver-side door jamb sticker before purchasing new rubber. This “Tire and Loading Information” placard lists the exact dimensions and cold inflation pressures specifically calibrated for your vehicle’s weight and suspension setup.
Standard Factory Tire Dimensions
For those looking for a quick reference, here are the most common configurations found on the 2019 model year. Most XLT models with the 200A or 201A equipment groups use the 275/65R18 size, which provides a plush ride thanks to the extra air volume in the taller sidewall.
The Limited trim and higher-tier XLT packages often move up to the 275/55R20 specification. This size is one of the most popular in the light truck and SUV market, offering a massive selection of all-season and all-terrain tread patterns from almost every major manufacturer.
Finally, the Platinum and high-end Limited editions utilize the 285/45R22. These tires are wider, providing a larger contact patch for better grip during highway cruising, though they can be more expensive to replace due to their specialized dimensions.
Understanding the Sidewall Markings
When you look at a tire like a 275/65R18, the numbers tell a specific story about the tire’s geometry. The “275” represents the section width in millimeters from sidewall to sidewall, while the “65” is the aspect ratio, meaning the sidewall height is 65% of the width.
The “R” stands for radial construction, which is the standard for modern passenger vehicles. The “18” indicates the wheel diameter in inches, and it is the one number you cannot change without buying new wheels to match.
Choosing the Right Tread Pattern for Your Lifestyle
Once you know your 2019 ford expedition tire size, you need to decide which type of tread best suits your driving habits. Most Expeditions come from the factory with All-Season (HT) tires, designed for a quiet ride, long tread life, and decent performance in rain or light snow.
However, if you frequently visit campsites or live in an area with unpaved roads, you might consider All-Terrain (AT) tires. These feature deeper grooves and more aggressive shoulder blocks to provide traction in mud and gravel without sacrificing too much highway comfort.
For those who live in the “Rust Belt” or high-altitude regions, a dedicated winter tire is often a better investment than an all-season. Look for the “Three-Peak Mountain Snowflake” (3PMSF) symbol on the sidewall, which indicates the tire meets specific snow traction performance requirements.
The Impact of Weight and Load Rating
The Expedition is a heavy vehicle, often weighing over 5,500 pounds before you even add passengers or cargo. This means you must pay close attention to the load index, usually a two or three-digit number following the tire size (e.g., 114 or 116).
Never install a tire with a lower load index than what the factory recommends. Doing so can lead to excessive heat buildup and potential sidewall failure, especially when towing a trailer or carrying a full load of gear.
Speed ratings are also important, typically denoted by a letter like “T,” “H,” or “V.” While you likely won’t be racing your Expedition, the speed rating also relates to the tire’s ability to dissipate heat, which is crucial for long-distance summer road trips.
Essential Tools and Safety Steps for DIY Tire Changes
Changing a tire on a full-size SUV requires more than just the basic kit found in the trunk. Because the 2019 Ford Expedition is so large, you need high-quality equipment to ensure the vehicle remains stable while it is off the ground.
If you are performing a seasonal swap in your garage, invest in a 3-ton hydraulic floor jack and a pair of heavy-duty jack stands. Never rely solely on a jack to hold the vehicle up while you are working; always lower it onto the stands for safety.
You will also need a 21mm deep-well socket and a torque wrench. Ford specifies a high torque value for the lug nuts on this vehicle, and getting it right is essential for preventing wheel vibration or warped brake rotors.
- Chock the wheels: Always place blocks in front of and behind the tires on the opposite end of the vehicle you are lifting.
- Loosen before lifting: Break the tension on the lug nuts while the tire is still touching the ground to prevent the wheel from spinning.
- Use factory lift points: Consult your owner’s manual to find the reinforced metal areas on the frame designed to support the vehicle’s weight.
The Importance of Torque Specs
For the 2019 Ford Expedition, the factory lug nut torque specification is typically 150 lb-ft (204 Nm). Using an impact wrench to “guess” the tightness often results in over-tightening, which can stretch the wheel studs or crack the alloy wheel.
Instead, use a calibrated torque wrench and tighten the nuts in a “star pattern.” This ensures the wheel sits perfectly flat against the hub assembly, preventing uneven brake wear and ensuring the wheel stays securely attached at highway speeds.
After driving about 50 to 100 miles on new tires or after a rotation, it is a “pro-tip” to re-check the torque. Components can settle slightly after a few heat cycles, and a quick check provides peace of mind.
Maintenance Tips for Longevity and Safety
Buying the correct 2019 ford expedition tire size is only half the battle; keeping them in good shape is where you save money. The most common cause of premature tire wear is improper inflation pressure, which can also drop your fuel economy by several miles per gallon.
Check your tire pressures at least once a month using a high-quality digital gauge. Do this when the tires are “cold,” meaning the car hasn’t been driven for at least three hours, as driving generates heat that artificially inflates the pressure readings.
Regular rotations are also mandatory for an SUV of this size. Because the front tires handle the steering and most of the braking forces, they wear differently than the rears. Rotating them every 5,000 to 7,500 miles ensures the tread wears evenly across all four corners.
Monitoring Tread Depth and Aging
You can use the “Penny Test” to check your tread depth. Insert a penny into the tread groove with Lincoln’s head upside down; if you can see the top of his head, you have less than 2/32 of an inch of tread remaining and need immediate replacement.
However, depth isn’t the only factor. Tires age chemically, and the rubber begins to harden and crack over time, a process known as dry rot. Even if a tire has plenty of tread, most manufacturers recommend replacement after six years of service.
Look for the DOT code on the sidewall, which ends in four digits. The first two digits are the week of manufacture, and the last two are the year. If your tires are from 2017 or earlier, it’s time to start shopping for a new set, regardless of how they look.
Common Problems and Troubleshooting
One frequent issue Expedition owners face is “cupping” or “feathering” of the tread. This usually manifests as a rhythmic humming sound that gets louder as you speed up. This is rarely a tire defect; instead, it usually points to worn shocks or struts or an alignment that is out of spec.
If you feel a vibration in the steering wheel at 60 MPH, your wheels likely need a professional balance. Modern 22-inch wheels are very sensitive to even a half-ounce discrepancy in weight distribution.
Another common concern is the Tire Pressure Monitoring System (TPMS) light. In many cases, a sudden drop in ambient temperature will trigger the light because air contracts when cold. Simply topping off the air to the pressure listed on your door jamb usually resolves the issue after a few miles of driving.
Alignment and Suspension Health
Because the Expedition uses an independent rear suspension (IRS), it requires a four-wheel alignment rather than just a front-end adjustment. If the rear alignment is off, the vehicle may “dog-track” or feel unstable when cornering.
Whenever you buy new tires, it is highly recommended to get a professional alignment. This protects your investment and ensures that your expensive new rubber doesn’t wear out prematurely due to “scrubbing” against the pavement.
If you notice the vehicle pulling to one side or the steering wheel is off-center while driving straight, schedule an alignment check immediately. These small adjustments can add thousands of miles to the life of your tires.
Frequently Asked Questions About 2019 Ford Expedition Tire Size
What is the most common 2019 ford expedition tire size?
The most frequent size found on the road is the 275/55R20. It is standard on most Limited trims and optional on the XLT. It offers a great mix of availability, price, and performance for both city driving and towing.
Can I put 18-inch wheels on an Expedition that came with 22s?
Yes, you can generally “downsize” to a smaller wheel as long as it clears the brake calipers. Many owners do this to gain more sidewall for off-roading. However, you must ensure the new 2019 ford expedition tire size has the same overall diameter to keep your speedometer accurate.
Does tire size affect the Expedition’s towing capacity?
While the size itself doesn’t change the engine’s power, the load rating of the tire is critical. Low-profile 22-inch tires often have less “give,” which can make the ride stiffer when towing. Always ensure your tires meet or exceed the factory Load Index rating of 114 or higher.
How do I reset the TPMS after changing my tires?
On the 2019 Expedition, the system usually resets itself after you drive for about 10-15 minutes at speeds above 20 MPH. If the light stays on, you may need a TPMS reset tool or a visit to a technician to relearn the sensor positions.
Final Thoughts on Choosing Your Tires
Selecting the right 2019 ford expedition tire size is about more than just matching numbers; it’s about tailoring your vehicle to your specific needs. From the rugged 18-inch options for the FX4 off-road package to the sleek 22-inch rollers on the Platinum, your tires are the foundation of your SUV’s performance.
Remember to prioritize load ratings and tread patterns that match your environment. A high-quality set of tires, combined with regular rotations and correct air pressure, will ensure your Expedition remains a reliable partner for all your adventures.
Stay proactive with your maintenance, keep an eye on those tread depths, and never hesitate to consult a professional if you notice unusual vibrations or wear patterns. Stay safe and stay comfortable!
