We promise to provide you with the technical clarity needed to make an informed purchase and the practical steps to maintain those tires for years to come. Let’s dive into the specifics of what makes your Ford Flex grip the road effectively.
Understanding the 2013 Ford Flex Tire Size by Trim Level
The 2013 Ford Flex came in several configurations, and the wheel diameter often changed based on the options selected at the dealership. Knowing your specific trim level is the first step in identifying the right fitment for your vehicle.
The base SE trim typically rolled off the assembly line with 17-inch wheels, utilizing a 235/60R17 tire. This size offers a taller sidewall, which provides a bit more cushion against potholes and rough city streets.
If you own the SEL or Limited trims, your 2013 ford flex tire size likely jumps to 18 or 19 inches. The standard SEL fitment is 235/55R18, while the Limited often features 235/55R19 or even the massive 20-inch 255/45R20 options on appearance packages.
The 17-Inch Configuration (Base SE)
The 17-inch setup is the most budget-friendly when it comes time for replacement. These tires are common and offer a wide variety of all-season tread patterns that prioritize longevity and a quiet ride.
The 18-Inch and 19-Inch Mid-Range Options
The 18-inch and 19-inch sizes are the “sweet spot” for many Flex owners. They provide a sharper steering response than the 17s without the higher cost and stiffer ride associated with 20-inch performance tires.
The 20-Inch Performance Setup
Found on the Limited and Titanium trims, the 20-inch wheels use a 255/45R20 tire. This wider footprint is necessary for the EcoBoost models, as it helps put that extra torque down to the ground more effectively.
Decoding the Tire Specifications for Your Flex
Reading the string of numbers on your sidewall can feel like deciphering a secret code. However, each segment of that code tells you exactly how the tire will perform under your vehicle’s weight.
Take the 235/55R19 size as an example. The “235” represents the width of the tire in millimeters from sidewall to sidewall, which determines how much contact you have with the road surface.
The “55” is the aspect ratio, meaning the height of the sidewall is 55% of the tire’s width. A lower number here usually means a “low-profile” tire, which improves handling but can make the ride feel firmer.
What the “R” and Diameter Mean
The “R” stands for radial, which refers to the internal construction of the tire where the cord plies run 90 degrees to the direction of travel. The “19” is simply the diameter of the wheel in inches.
Understanding the Load Index
The Ford Flex is a heavy vehicle, often weighing over 4,600 pounds. You must ensure your new tires have a load index of at least 101 to 105 to safely support the vehicle and its passengers.
Speed Ratings for the Flex
Most Flex tires carry an “H” or “V” speed rating. While you likely aren’t taking your crossover to a race track, these ratings indicate the tire’s ability to dissipate heat during long highway drives.
The Importance of Seasonal Tire Selection
Your 2013 ford flex tire size remains the same, but the rubber compound you choose should change based on your local climate. Not all tires are created equal when the temperature drops or the rain starts to fall.
All-season tires are the standard choice for most drivers. They are designed to provide adequate traction in dry, wet, and light snowy conditions, making them a versatile “set-it-and-forget-it” option.
However, if you live in a region with heavy snowfall, dedicated winter tires are a lifesaver. The rubber in winter tires stays flexible in freezing temperatures, allowing the tread to “bite” into ice and packed snow.
- All-Season: Best for mild climates and long-distance highway cruising.
- Winter/Snow: Essential for temperatures consistently below 45 degrees Fahrenheit.
- Performance: Ideal for EcoBoost owners who want maximum dry-grip and cornering stability.
For those who occasionally venture off the beaten path to a campsite, consider an all-terrain tire if you have the 17 or 18-inch wheels. These offer tougher sidewalls to resist punctures from gravel and rocks.
Why Correct Tire Pressure Matters for Your Flex
Maintaining the proper inflation is the easiest way to extend the life of your tires. For the 2013 Ford Flex, the recommended pressure is usually 35 PSI (pounds per square inch) for all four tires.
Under-inflated tires create excess heat and cause the outer edges of the tread to wear prematurely. This also forces your engine to work harder, which can significantly drop your fuel economy over time.
Over-inflation is equally problematic, as it causes the center of the tire to wear out faster and makes the ride feel incredibly bouncy. Always check your pressure when the tires are “cold” for the most accurate reading.
- Locate the tire information placard on the driver-side door jamb.
- Use a high-quality digital pressure gauge to check each tire.
- Add or release air until you reach the manufacturer’s spec (35 PSI).
- Don’t forget to check the spare tire in the cargo area!
Your Flex is equipped with a Tire Pressure Monitoring System (TPMS). If the light on your dashboard illuminates, it means at least one tire is 25% below the recommended pressure level.
Upgrading and Customizing Your 2013 Ford Flex Tire Size
Some owners want to change their 2013 ford flex tire size to achieve a different look or improved performance. While customization is possible, you must stay within certain mechanical limits to avoid damaging your drivetrain.
If you have an All-Wheel Drive (AWD) Flex, all four tires must be the exact same size and have nearly identical tread depth. Different sizes can trick the AWD system into thinking a wheel is slipping, leading to expensive transmission damage.
When “plus-sizing” your wheels (moving from 18s to 20s), you must reduce the sidewall height to keep the overall diameter the same. This ensures your speedometer remains accurate and your tires don’t rub against the wheel wells.
The Risks of Oversized Tires
Installing tires that are too large can interfere with the suspension components and brake lines. It can also put extra strain on the power steering pump when you are navigating tight parking lots.
Using a Tire Size Calculator
Before buying a non-standard size, use an online tire size calculator. Aim to keep the overall diameter within 3% of the original factory tire to maintain safety and performance standards.
Step-by-Step: Checking Your Tire Tread Depth
You don’t need fancy tools to know when your tires are spent. A simple “penny test” can tell you if your 2013 ford flex tire size is no longer providing enough grip for rainy weather.
Take a penny and insert it into the tread groove with Abraham Lincoln’s head facing down. If you can see the top of his head, your tread is below 2/32 of an inch, and it is time for a new set.
For better safety in the rain, many experts recommend replacing tires when they reach 4/32 of an inch. This extra tread helps channel water away from the contact patch, preventing dangerous hydroplaning incidents.
While you are checking the tread, look for “cupping” or uneven wear. This often indicates that your Flex needs a wheel alignment or that your shocks and struts are beginning to fail.
Frequently Asked Questions About 2013 Ford Flex Tire Size
What is the most common 2013 ford flex tire size?
The most common size found on the popular SEL trim is 235/55R18. This size offers a great balance of comfort, availability, and price for the average owner.
Can I put 20-inch wheels on a Flex that came with 17s?
Yes, you can upgrade to 20-inch wheels. However, you must use the 255/45R20 tire size to ensure the total height of the wheel and tire matches the original factory specifications.
How often should I rotate the tires on my Ford Flex?
You should rotate your tires every 5,000 to 7,500 miles. Regular rotations help ensure even wear, especially on AWD models where the front tires often wear faster due to steering forces.
Does the 2013 Ford Flex require a special type of tire?
No special “type” is required, but you must ensure the tires meet the Extra Load (XL) or high load index requirements. The Flex is a heavy vehicle, and standard passenger tires may not be sufficient.
What is the lug nut torque spec for the 2013 Ford Flex?
When installing your wheels, use a torque wrench to tighten the lug nuts to 100 lb-ft in a star pattern. This ensures the wheel is seated evenly against the brake rotor.
Final Thoughts on Choosing Your Tires
Selecting the right tires for your Ford Flex is about more than just looking at the numbers on the sidewall. It is about ensuring your family stays safe, your ride remains quiet, and your vehicle handles as the engineers intended.
Always prioritize quality brands and ensure your 2013 ford flex tire size matches your specific trim and wheel diameter. By keeping an eye on your tire pressure and tread depth, you can maximize your investment and enjoy the road ahead.
If you ever feel unsure about a specific tire’s compatibility, consult with a certified technician or a reputable tire shop. Proper fitment is the foundation of a safe and reliable driving experience. Stay safe and enjoy the journey in your Ford Flex!
