The 2021 Lincoln Trucks Corsair sits in the modern luxury crossover category, blending compact luxury packaging with everyday road manners and a more contemporary wheel-and-tire approach than earlier collector-era Lincoln models. For this exact Corsair, tire selection starts with identifying the correct configuration, because three primary radial sizes are used: 225/60R18, 225/55R19, and 245/45R20. Those sizes stay close in overall diameter while changing rim diameter and section width, so the real decision is matching the tire to the vehicle’s sub-model and wheel setup. Once that is confirmed, the focus shifts to appearance, brand, sidewall style, and intended street use.
Which Tire Size Is Right for The 2021 Lincoln Trucks Corsair
The 2021 Lincoln Trucks Corsair uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All three are radial metric sizes, but they do not share the same rim size, so the first step is confirming whether the vehicle is on 18-inch, 19-inch, or 20-inch wheels before comparing tire options.
Fit(s): Base, Grand Touring Plug-In Hybrid, and Reserve
Construction: Radial|Rim: 19 in
In 225/55R19, the 225 identifies the nominal section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 19 is the rim diameter in inches. This is one of the primary modern radial fitments used on the 2021 Lincoln Trucks Corsair and appears across more than one sub-model. It represents a middle-ground factory-style sizing approach within the Corsair range, bridging the smaller 18-inch setup and the larger 20-inch package. Buyers considering this size should confirm that the vehicle actually carries 19-inch wheels before moving on to tread, brand, or performance-oriented choices.
In 225/60R18, the tire measures 225 millimeters in nominal section width, uses a 60-series profile, features radial construction, and fits an 18-inch wheel. On the 2021 Lincoln Trucks Corsair, this size is associated with specific configurations rather than the full model range. Its dimensions keep overall height close to the other Corsair fitments while pairing with the smallest rim diameter used on this vehicle. That makes wheel confirmation especially important, since moving between 18-inch and larger-wheel setups is not just a matter of tire choice but of matching the actual wheel on the vehicle.
In 245/45R20, the 245 indicates a wider nominal section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 20 is the wheel diameter in inches. This size is used on certain 2021 Lincoln Trucks Corsair sub-models and has the strongest visible product variety here, including BFGoodrich, Nitto, and Pro-Trac options. Available versions include Blackwall, Redline, and RWL sidewall treatments across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Street Pro III. It is the size to evaluate when the Corsair has the 20-inch wheel package and a buyer wants more choice in style and tire character.
Sub-model fitment matters on the 2021 Lincoln Trucks Corsair because the tire size changes with the specific trim and wheel package. Before selecting a tire, confirm the exact sub-model and then verify the wheel diameter currently on the vehicle, especially if the wheels may have been changed.

2021 Lincoln Trucks Corsair Base
The 2021 Lincoln Trucks Corsair Base uses either a 225/60R18 or 225/55R19 radial tire, so this sub-model does not point to just one wheel-and-tire setup. Tire selection starts with confirming whether the vehicle is on 18-inch or 19-inch wheels, then choosing within the correct metric radial size.
2021 Lincoln Trucks Corsair Grand Touring Plug-In Hybrid
The 2021 Lincoln Trucks Corsair Grand Touring Plug-In Hybrid uses either 225/55R19 or 245/45R20 radial tires depending on wheel configuration. That makes wheel diameter the key fitment checkpoint, followed by comparing available tire styles and series within the correct size.
The 2021 Lincoln Trucks Corsair Reserve uses either 225/55R19 or 245/45R20 radial tires rather than a single universal size. Once the 19-inch or 20-inch wheel setup is confirmed, the buying decision becomes a matter of selecting the right product style, brand, and sidewall treatment for the vehicle’s intended use.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2021 Lincoln Trucks Corsair?
The 2021 Lincoln Trucks Corsair uses three primary tire sizes: 225/60R18, 225/55R19, and 245/45R20. All are radial metric sizes, but they are not interchangeable as one universal fitment because they are tied to different wheel diameters and sub-model configurations.
The best starting point is the wheel that is actually on the vehicle. An 18-inch wheel requires the 225/60R18 fitment, a 19-inch wheel uses 225/55R19, and a 20-inch wheel uses 245/45R20. If the Corsair has had wheel changes, rely on the current wheel diameter and overall clearance rather than trim name alone.
What size rim does a 2021 Lincoln Trucks Corsair use?
The 2021 Lincoln Trucks Corsair uses 18-inch, 19-inch, or 20-inch rims depending on the exact sub-model and wheel package. Those rim diameters correspond to 225/60R18, 225/55R19, and 245/45R20 tire sizes, all in radial construction.
Rim diameter should be confirmed before anything else, because a tire must match the wheel diameter exactly. The sidewall markings on the current tire can help verify what is installed, but it is also smart to inspect the wheel itself and confirm that the vehicle has not been fitted with aftermarket wheels that change the intended setup.
Why does the 2021 Lincoln Trucks Corsair have more than one tire size?
More than one tire size is used on the 2021 Lincoln Trucks Corsair because different sub-models and wheel packages carry different rim diameters. The Base can use 225/60R18 or 225/55R19, while the Grand Touring Plug-In Hybrid and Reserve use 225/55R19 or 245/45R20.
Although the overall tire diameters stay fairly close, the wheel diameter and tire profile change from one setup to another. That means the correct choice is not simply the largest or most common size. Matching the actual wheel on the vehicle is the priority, followed by checking width, clearance, and the exact configuration before purchasing replacement tires.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2021 Lincoln Trucks Corsair?
Start with the basics: 245/45R20 is the correct radial size only for Corsair configurations that actually use a 20-inch wheel. Within that size, available options vary by brand, tire series, sidewall style, rim-width specification, and details such as load figures and product weight.
Once the size is confirmed, the real choice becomes the kind of tire presentation and road use that suits the vehicle. Some buyers will focus on a straightforward Blackwall performance look, while others may want Redline or RWL styling. Wheel width should also be checked so the selected tire matches the wheel and intended fitment properly.
What sidewall styles are available for 2021 Lincoln Trucks Corsair tires?
For the 245/45R20 fitment used on certain 2021 Lincoln Trucks Corsair configurations, available sidewall styles include Blackwall, Redline, and RWL. Blackwall appears across several BFGoodrich and Nitto offerings, while Pro-Trac Street Pro III is available in both Redline and RWL versions.
Sidewall style does not change the basic size requirement, but it can significantly change the look of the vehicle. Buyers who want a more understated modern appearance may lean toward Blackwall, while Redline or raised white letter styling creates a more distinct visual statement. The key is choosing the sidewall treatment within the correct 20-inch fitment.
What brands offer tires for the 2021 Lincoln Trucks Corsair?
Brand choice is most clearly represented in the 245/45R20 Corsair fitment, where BFGoodrich, Nitto, and Pro-Trac are available. Those options span several tire series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand should be compared alongside the exact size, sidewall style, and wheel compatibility rather than treated as the only buying factor. A Corsair owner may prefer one product because of appearance, another because of series character, and another because it suits the installed wheel width more closely. The smartest comparison starts with fitment, then narrows to brand and series.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2021 Lincoln Trucks Corsair?
The 2021 Lincoln Trucks Corsair is a modern vehicle using radial tire fitments, so the appearance question is less about bias-ply versus radial and more about wheel-and-sidewall presentation within the correct radial size. Choices such as Blackwall, Redline, or RWL can noticeably change the vehicle’s overall visual character.
A restoration-minded or appearance-focused owner should match the look of the tire to the vehicle’s wheel package and intended style rather than chase a generic look. Since this is a late-model luxury crossover, keeping the correct metric radial size and proper wheel diameter matters more than trying to force a vintage-style presentation that does not suit the platform.
Does correct tire fitment matter for a 2021 Lincoln Trucks Corsair restoration?
Correct tire fitment matters on a 2021 Lincoln Trucks Corsair because the vehicle uses multiple wheel diameters and associated radial sizes. A restoration or preservation project should retain the proper relationship between the tire size, wheel diameter, and sub-model configuration instead of assuming one Corsair size works across every version.
Appearance is only part of the equation. Proper fitment also affects wheel compatibility, stance, and the way the vehicle fills the wheel opening. On a modern Lincoln crossover, staying true to the intended 18-inch, 19-inch, or 20-inch setup usually preserves the most coherent result, especially when replacing tires on vehicles that may already have altered wheels.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Lincoln Trucks Corsair?
Yes, modifications can affect tire fitment on a 2021 Lincoln Trucks Corsair. Aftermarket wheels, changes in wheel width, suspension lowering, alignment changes, or body alterations can all influence which of the Corsair’s original tire sizes still makes sense on the vehicle.
A Corsair that no longer carries its original wheel setup should be measured rather than matched by trim name alone. Check wheel diameter first, then confirm width and available clearance at the strut, fender, and steering range. Even when the tire size looks close on paper, a modified wheel-and-suspension combination can change the fitment outcome.
What should I inspect before driving a 2021 Lincoln Trucks Corsair on new tires?
Before road use, inspect the wheel diameter, tire size markings, air pressure, and the basic condition of the wheels themselves. It is also wise to confirm that the tires clear suspension components and bodywork properly, especially if the Corsair has a different wheel package than it had when new.
A careful once-over should also include lug hardware, valve stems, tread seating, and any signs of rubbing during full steering lock. After the first miles, recheck pressure and look for unusual wear or scuffing. Those early checks help confirm that the selected 18-inch, 19-inch, or 20-inch fitment is working as intended on the vehicle.
How often should tires on a 2021 Lincoln Trucks Corsair be inspected?
Tires on a 2021 Lincoln Trucks Corsair should be inspected regularly, not just when they look worn. A visual check for cuts, punctures, sidewall damage, irregular wear, and air loss is good routine practice, particularly on a vehicle that may see mixed daily and occasional-use driving.
Inspection becomes even more important when the vehicle uses larger wheel packages such as 19-inch or 20-inch setups, since profile changes can make condition issues more noticeable in ride and handling. It also helps to inspect after seasonal temperature swings, long trips, or contact with potholes and curbs so minor problems are caught before they become larger ones.
