The 2011 Ford Trucks F-150 FX2 came from a period when Ford was blending full-size pickup capability with a more street-oriented sport-truck look. As a rear-wheel-drive FX-series model, it often appeals to owners who want factory-era stance and appearance without losing everyday usability. Tire fitment centers on two radial sizes, 265/60R18 and 275/55R20, so the first step is confirming which wheel package is actually on the truck. That choice shapes overall look, sidewall profile, and replacement selection. For any FX2 that has been modified or fitted with different wheels, wheel diameter and clearance should be verified before choosing a replacement tire.
Which Tire Size Is Right for The 2011 Ford Trucks F-150 FX2
The 2011 Ford Trucks F-150 FX2 uses two primary tire sizes, and the difference comes down to wheel diameter rather than a change from bias-ply to radial construction. Both sizes are radial, but one fits an 18-inch rim and the other fits a 20-inch rim, so confirming the actual wheel setup on the truck is the key first step before selecting a tire.
265/60R18 is a metric radial size in which 265 identifies the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 2011 Ford Trucks F-150 FX2, this size suits the 18-inch wheel setup and keeps the selection process focused on the correct modern radial format. Buyers comparing tires in this size should pay attention to overall dimensions, intended use, and wheel compatibility. It is a practical choice when the truck retains its original 18-inch wheel diameter or has been kept with the same fitment.
275/55R20 is also a metric radial size, with 275 representing nominal section width in millimeters, 55 identifying the aspect ratio, R marking radial construction, and 20 showing the rim diameter in inches. For the 2011 Ford Trucks F-150 FX2, this size belongs to the 20-inch wheel configuration and gives the truck a lower-profile tire than the 18-inch setup. Selection here is less about decoding an older sizing system and more about matching the exact wheel diameter already on the vehicle. Checking clearance and confirming the truck has not been changed to a different wheel package remains important.
Fitment is straightforward here because the covered FX2 sub-model shares the same two radial tire-size paths as the overall model page. The important detail is not trim distinction, but confirming whether the truck is wearing 18-inch or 20-inch wheels before choosing a replacement tire.

Frequently Asked Questions
These FAQs focus on the two tire sizes used on the 2011 Ford Trucks F-150 FX2, along with rim fitment, selection factors, modifications, and the maintenance checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2011 Ford Trucks F-150 FX2?
The 2011 Ford Trucks F-150 FX2 uses two primary tire sizes: 265/60R18 and 275/55R20. Both are radial tire sizes, and each one corresponds to a different wheel diameter, so the truck does not use them interchangeably on the same rim.
Choosing between them starts with confirming the wheel diameter currently on the vehicle. An FX2 with 18-inch wheels takes 265/60R18, while one with 20-inch wheels takes 275/55R20, and any truck that has been modified should also be checked for wheel width, clearance, and overall tire dimensions before replacement.
What size rim does a 2011 Ford Trucks F-150 FX2 use?
A 2011 Ford Trucks F-150 FX2 uses either an 18-inch or 20-inch rim, depending on which tire size is on the truck. The 265/60R18 size fits an 18-inch wheel, and the 275/55R20 size fits a 20-inch wheel.
That means rim diameter has to be verified before ordering or mounting tires. Looking only at the truck model is not enough, because both wheel diameters are correct within this FX2 fitment range, and trucks with aftermarket wheels should also have actual wheel width and clearance checked before a replacement tire is chosen.
Why does the 2011 Ford Trucks F-150 FX2 have more than one tire size?
The 2011 Ford Trucks F-150 FX2 has more than one tire size because it was fitted with more than one wheel diameter. The two sizes, 265/60R18 and 275/55R20, are both radial fitments, but they are tied to different wheel packages rather than different tire constructions.
For an owner, that means the real question is which wheel setup the truck has today. A used FX2 may still wear its original wheel package, or it may have been changed over time, so checking the actual wheel diameter and comparing the current tire size on the truck is the most reliable way to avoid a mismatch.
Choosing the Right Tire
What should I consider when choosing a tire for a 2011 Ford Trucks F-150 FX2?
Start with the correct tire size for the wheel diameter on the truck: 265/60R18 for an 18-inch rim or 275/55R20 for a 20-inch rim. Since both are radial sizes, the next considerations are the tire's intended use, overall dimensions, and compatibility with the truck's existing wheel setup.
A street-driven FX2 may call for different priorities than a truck used for frequent hauling or mixed driving. It helps to confirm load capability, compare the physical size of the replacement against the current setup, and inspect whether the truck has wheel, suspension, or ride-height changes that could affect clearance.
How do I choose between the available 265/60R18 and 275/55R20 tires for a 2011 Ford Trucks F-150 FX2?
The choice between 265/60R18 and 275/55R20 is not a matter of preference alone, because each size belongs to a different wheel diameter. A 2011 Ford Trucks F-150 FX2 with 18-inch wheels needs 265/60R18, while a truck with 20-inch wheels needs 275/55R20.
Once the correct size is confirmed, compare tires within that size rather than across both sizes. Focus on how the truck is used, whether it remains close to stock, and whether the replacement tire matches the current wheel dimensions and available space around the fenders, suspension, and steering components.
What rim-fitment details should I compare when choosing 2011 Ford Trucks F-150 FX2 tires?
Rim diameter is the first fitment detail to compare, because this truck uses either an 18-inch or 20-inch wheel. The selected tire must match that wheel diameter exactly, with 265/60R18 tied to the 18-inch setup and 275/55R20 tied to the 20-inch setup.
After confirming diameter, it is smart to verify actual wheel width and the truck's current overall setup before changing tires. That becomes especially important if the FX2 has custom wheels, a lowered stance, or other modifications that can change how much room the tire has at full steering lock and under suspension movement.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Ford Trucks F-150 FX2?
For a period-style 2011 Ford Trucks F-150 FX2, the right starting point is the tire size that matches the truck's actual wheel package: 265/60R18 on 18-inch rims or 275/55R20 on 20-inch rims. Staying with the correct size preserves the truck's intended stance and helps keep the overall look in line with its model-year character.
Appearance on a truck from this era is closely tied to sidewall profile and wheel diameter, so an 18-inch setup and a 20-inch setup do not present the same look. Owners aiming for a factory-era visual style should compare the current wheels and tire proportions carefully before changing sizes.
Does correct tire fitment matter for a 2011 Ford Trucks F-150 FX2 restoration or clean factory-era presentation?
Correct tire fitment matters because the 2011 Ford Trucks F-150 FX2 was built around specific radial sizes tied to specific wheel diameters. Using 265/60R18 or 275/55R20 as appropriate helps maintain the truck's proper proportions and avoids the mismatched appearance that can come from the wrong tire profile.
A clean factory-era presentation depends on more than the size stamped on the sidewall. Wheel diameter, tire height, and sidewall shape all influence how the truck sits and fills the wheel openings, so checking the complete wheel-and-tire package is just as important as choosing the right nominal size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Ford Trucks F-150 FX2?
Yes, modifications can affect tire fitment on a 2011 Ford Trucks F-150 FX2 even when the tire size looks close to stock. Changes such as aftermarket wheels, altered wheel offset, suspension lowering, or other ride-height adjustments can reduce clearance and change how the tire sits in the wheel opening.
That is why a modified FX2 should be checked at the wheel, not just by model name. Tire diameter, section width, steering clearance, and suspension travel all deserve a careful look before replacement, especially if the truck has already been customized from its original 18-inch or 20-inch configuration.
What should I inspect before driving a 2011 Ford Trucks F-150 FX2 on new tires?
Before driving a 2011 Ford Trucks F-150 FX2 on new tires, inspect the wheels, confirm the tire size matches the rim diameter, and make sure the tires are inflated properly for the vehicle's needs. It is also worth checking for visible interference at the fenders, suspension, and steering components.
A short initial road test is useful after installation because it can reveal rubbing, vibration, or other fitment issues that are easy to miss while the truck is parked. Lug hardware, alignment condition, and the general state of the suspension should also be looked over, particularly on an older daily-driven pickup.
How often should tires on a 2011 Ford Trucks F-150 FX2 be inspected?
Tires on a 2011 Ford Trucks F-150 FX2 should be inspected regularly, not only when tread looks worn. Routine checks should include inflation pressure, uneven wear, cracking, cuts, bulges, and any signs of air loss, especially if the truck sees mixed use or long periods between drives.
Frequent inspection matters because a full-size pickup can hide developing problems until they affect ride quality or handling. It is smart to look over the tires before longer trips, after any suspension or wheel change, and whenever the truck begins to pull, vibrate, or show irregular wear across the tread.
