The 2011 Ford Trucks F-150 Lariat sits in the heart of the modern full-size pickup era, blending upscale trim, everyday usability, and the kind of wheel-and-tire variety that can change the truck’s stance and road manners noticeably. On this exact model, tire fitment centers on three primary radial sizes: 265/60R18, 275/55R20, and 275/65R18. That makes the first decision less about brand loyalty and more about confirming whether the truck is a 4x2 or 4x4 and whether it rides on 18-inch or 20-inch wheels. Once that is settled, the focus shifts to proper metric sizing, sidewall presentation, and the truck’s intended street or light-trail use.
Which Tire Size Is Right for The 2011 Ford Trucks F-150 Lariat
Three tire sizes apply to the 2011 Ford Trucks F-150 Lariat, and they vary by sub-model and wheel diameter. The key first step is confirming whether the truck is a 4x2 or 4x4, then verifying whether it has 18-inch or 20-inch wheels. All three are radial metric sizes, so the decision is about matching the truck’s exact configuration before comparing tread style, sidewall treatment, and other product differences.
265/60R18 is a metric radial size in which 265 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2011 Ford Trucks F-150 Lariat, this size belongs on an 18-inch wheel and is part of the truck’s modern radial fitment. Its dimensions give buyers a useful reference point when confirming wheel size and comparing against other Lariat tire options. This size should be matched to the truck’s exact sub-model and current wheel setup before selecting a replacement.
275/55R20 is a metric radial size that uses a 275-millimeter nominal section width, a 55-series profile, radial construction, and a 20-inch rim diameter. For the 2011 Ford Trucks F-150 Lariat, this size represents the 20-inch wheel fitment and appears across more than one sub-model configuration. Its lower-profile format compared with the 18-inch sizes makes wheel confirmation especially important before purchase. Buyers considering this size should verify that the truck still has its intended 20-inch wheel package and has not been changed to a different wheel or tire combination.
275/65R18 is a metric radial size with a 275-millimeter nominal section width, a 65-series profile, radial construction, and an 18-inch rim diameter. On this F-150 Lariat application, it serves a different role than the 20-inch option and should be selected only for the configurations that use it. Available product coverage in this size includes BFGoodrich’s All-Terrain T/A KO2 with raised white letter sidewalls, giving it a more aggressive truck-oriented look. This is the size to examine closely when the goal includes all-terrain character as well as correct 18-inch fitment.
Sub-model fitment matters on the 2011 Ford Trucks F-150 Lariat because the tire size depends on whether the truck is a 4x2 or 4x4 and which wheel diameter it carries. The 20-inch fitment overlaps both, while the 18-inch choices split by drivetrain, so the exact configuration should be confirmed first.

These FAQs focus on the tire sizes used on the 2011 Ford Trucks F-150 Lariat, how 4x2 and 4x4 fitment can differ, what the metric sizes mean, and what to inspect before putting the truck back into regular road use.
Tire Size & Fitment
What tire size fits a 2011 Ford Trucks F-150 Lariat?
The 2011 Ford Trucks F-150 Lariat uses three primary tire sizes: 265/60R18, 275/55R20, and 275/65R18. All three are radial metric sizes, and the correct one depends on the truck’s exact sub-model and wheel package rather than the Lariat trim name alone.
The practical next step is to confirm whether the truck is a 4x2 or 4x4 and then verify whether it has 18-inch or 20-inch wheels. That matters because two 18-inch sizes are used across different configurations, while 275/55R20 overlaps both drivetrains. A close look at the current tire sidewall and wheel diameter is the simplest way to avoid ordering the wrong size.
What size rim does a 2011 Ford Trucks F-150 Lariat use?
A 2011 Ford Trucks F-150 Lariat uses either an 18-inch or 20-inch rim, depending on the tire size on the truck. The 265/60R18 and 275/65R18 sizes are for 18-inch wheels, while 275/55R20 is for a 20-inch wheel.
Rim diameter needs to be confirmed before anything else, because a tire built for an 18-inch wheel cannot be mounted on a 20-inch wheel, and the reverse is also true. It is also wise to check the actual wheel currently on the truck, especially if it has had aftermarket wheels added or the original wheel package was changed at some point.
Do all 2011 Ford Trucks F-150 Lariat sub-models use the same tire size?
No. The 2011 Ford Trucks F-150 Lariat 4x2 and 4x4 do not share one single tire size across every configuration. Both can use 275/55R20, but the 4x2 also uses 265/60R18, while the 4x4 uses 275/65R18.
That overlap can make the truck seem simpler than it is, especially when looking only at trim level. The safest approach is to confirm the exact sub-model and then verify the current wheel diameter and tire code on the truck. That extra check helps prevent mixing up the two 18-inch sizes, which are not the same even though they share the same rim diameter.
Choosing the Right Tire
What should I consider when choosing a tire for a 2011 Ford Trucks F-150 Lariat?
Start with the correct size for the truck’s exact setup: 265/60R18, 275/55R20, or 275/65R18. From there, compare construction, intended use, sidewall style, rim-width compatibility where available, and any load information tied to the specific tire you are considering.
A street-driven Lariat may call for a different tire character than one used on rougher surfaces or light trails. The current wheel diameter, the truck’s actual sub-model, and whether the suspension or wheels have been changed should all be checked before making a final choice. Matching the truck’s real-world use matters just as much as matching the printed tire size.
What sidewall styles are available for 2011 Ford Trucks F-150 Lariat tires?
Among the currently represented options for this application, 275/65R18 includes an RWL sidewall, which means raised white letter styling. That gives the tire a more traditional truck presentation than a plain black sidewall and can be part of the overall look as much as the tread itself.
Sidewall appearance should always come after confirming the correct size and wheel diameter. Once fitment is right, the visual choice can help shape whether the truck looks more street-oriented, more utility-focused, or more in line with a rugged all-terrain style. The sidewall you choose should also suit how the Lariat is used and maintained, not just how it looks parked.
What brands offer tires for the 2011 Ford Trucks F-150 Lariat?
BFGoodrich is represented in the available product coverage for the 2011 Ford Trucks F-150 Lariat, including a 275/65R18 All-Terrain T/A KO2 option. That gives buyers in this size a recognized truck-tire choice with radial construction and a more aggressive all-terrain character.
Brand comparison only helps after the correct tire size has been pinned down, since this truck uses more than one fitment. It is also worth comparing details such as rim-width range, sidewall style, load specification, and tire series rather than choosing by brand name alone. Those factors often matter more to day-to-day use than the label on the sidewall.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Ford Trucks F-150 Lariat?
A period-style approach for a 2011 Ford Trucks F-150 Lariat starts with keeping the truck in its correct original-size range for its exact 4x2 or 4x4 configuration and wheel diameter. Because this is a modern truck application, the right visual direction usually comes from staying with the proper metric radial size rather than changing tire construction.
Appearance then becomes a matter of tread character and sidewall treatment within the correct fitment. A truck-oriented option such as an all-terrain radial can change the look noticeably, while still remaining within an appropriate size family. If originality matters closely, compare the truck’s current setup with window-sticker, build-sheet, or marque-specific references before changing wheel-and-tire presentation.
Does correct tire fitment matter for a 2011 Ford Trucks F-150 Lariat restoration?
Yes, correct tire fitment matters because wheel diameter and size selection are part of the truck’s stance, proportions, and intended character. On a 2011 Ford Trucks F-150 Lariat, using the wrong 18-inch or 20-inch size can alter the way the truck looks and may move it away from a clean, properly sorted presentation.
Fitment also affects practical details beyond appearance. The wrong size can create clearance issues, change the visual balance of the wheel opening, or complicate replacement planning later. Even on a newer collector-era truck, keeping the correct size family for the actual sub-model is one of the simplest ways to preserve a coherent restoration or preservation approach.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Ford Trucks F-150 Lariat?
Yes. Modifications such as aftermarket wheels, suspension lifts, leveling kits, lowering changes, or body alterations can affect tire fitment on a 2011 Ford Trucks F-150 Lariat. Even when the truck still uses one of its original size codes, changes in wheel width or offset can alter clearance and overall compatibility.
A truck that has been modified should be checked at the wheel wells, steering lock points, and suspension travel points before new tires are selected. It is also smart to confirm the actual wheel diameter on the truck rather than assuming it still has its original setup. That helps avoid conflicts between the intended tire size and the vehicle’s current hardware.
What should I inspect before driving a 2011 Ford Trucks F-150 Lariat on new tires?
Before regular road use, inspect tire pressure, wheel-nut torque, sidewall condition, tread seating, and any signs of rubbing after installation. It is also wise to look over the truck’s suspension, steering components, and alignment condition, since worn parts can affect how new tires wear and behave.
A short, careful test drive can reveal issues that are easier to correct early, such as vibration, pull, or contact at full steering lock. Rechecking pressure after the first drive is a good habit, especially on a truck that may carry varying loads. If the F-150 has sat for long periods, a broader check of brakes and wheel bearings is also worthwhile.
How should tires on a 2011 Ford Trucks F-150 Lariat be maintained?
Tires on a 2011 Ford Trucks F-150 Lariat should be maintained with regular pressure checks, visual inspections, and rotation intervals that suit the truck’s use. Watch for uneven wear, cuts, punctures, bulges, and sidewall damage, especially if the truck sees rough roads, towing duty, or occasional off-pavement use.
Storage and inactivity matter too, even on a modern truck. Long periods of sitting can hide air loss and allow age-related cracking to develop before mileage becomes an issue. Keeping the truck on clean, properly inflated tires and checking them before longer trips helps preserve ride quality and reduces the chance of discovering a preventable problem once the truck is already on the road.
