The 2010 Lincoln MKS brought Lincoln’s full-size sedan into a more modern touring role, blending contemporary styling, available EcoBoost power, and large-wheel presence in a way that feels very different from older American luxury cars. Tire selection on this car is closely tied to wheel package and sub-model, with 235/55R18, 255/45R19, and 245/45R20 radial fitments all appearing on the 2010 Lincoln MKS. That means the real decision starts with confirming the exact wheel diameter on the car. From there, available choices can include different performance-oriented series, Blackwall styling, and select Redline or raised white letter options in 245/45R20.
Which Tire Size Is Right for The 2010 Lincoln MKS
The 2010 Lincoln MKS uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel package on the car. Because these fitments span 18-inch, 19-inch, and 20-inch rims, the first step is confirming actual wheel diameter before choosing a tire. Once that is settled, the decision shifts to matching the proper radial size and comparing available product styles within that fitment.
In 235/55R18, 235 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. This is a modern radial fitment for the 2010 Lincoln MKS and is tied to an 18-inch wheel setup rather than the larger 19-inch or 20-inch packages. Its overall dimensions should be kept in mind if the car has been modified or fitted with non-original wheels. This size is the right path only after confirming that the car is actually using the 18-inch rim package.
In 245/45R20, the 245-millimeter width is paired with a 45-series profile and radial construction on a 20-inch rim. On the 2010 Lincoln MKS, this size reflects one of the larger wheel-package fitments and brings the widest visible range of product choice. Available tires include BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, Redline, and raised white letter sidewall treatments appearing in this size. It is the fitment to evaluate when the car already wears 20-inch wheels and the goal is to compare both modern performance character and appearance.
The 255/45R19 size uses a 255-millimeter nominal width, a 45-series profile, radial construction, and a 19-inch rim diameter. For the 2010 Lincoln MKS, this fitment sits between the 18-inch and 20-inch wheel packages and should be treated as its own setup rather than as a variation of the others. Wheel diameter confirmation matters because the similar overall proportions of these sizes do not make them interchangeable by default. This is the correct size to pursue only when the car is equipped with the 19-inch wheel package.
Sub-model fitment on the 2010 Lincoln MKS is not completely uniform, so identifying the exact version of the car matters before selecting tires. The Base model spans three wheel and tire sizes, while the EcoBoost uses the 19-inch and 20-inch radial fitments.

2010 Lincoln MKS Base
The 2010 Lincoln MKS Base can use 235/55R18, 255/45R19, or 245/45R20 radial tires depending on the wheel setup on the car. That makes wheel-diameter confirmation the first step, followed by comparing the available tire styles and series within the matching size.
The 2010 Lincoln MKS EcoBoost uses the larger 255/45R19 or 245/45R20 radial fitments rather than the 18-inch setup. Tire selection starts with confirming whether the car is on 19-inch or 20-inch wheels, then narrowing the choice by appearance and product type.
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 2010 Lincoln MKS?
The 2010 Lincoln MKS uses three primary radial tire sizes: 235/55R18, 255/45R19, and 245/45R20. The Base model can use all three, while the EcoBoost uses 255/45R19 or 245/45R20.
The key is matching the tire to the wheel package actually on the car. Since these sizes are tied to different rim diameters, checking the wheel itself is more important than assuming fitment from trim name alone, especially if the car has changed hands or has aftermarket wheels.
What size rim does a 2010 Lincoln MKS use?
A 2010 Lincoln MKS uses 18-inch, 19-inch, or 20-inch rims depending on configuration. The corresponding tire sizes are 235/55R18 for 18-inch wheels, 255/45R19 for 19-inch wheels, and 245/45R20 for 20-inch wheels.
Rim diameter should be confirmed before anything else because the MKS does not use one universal wheel size. It also helps to verify wheel width and the actual stamped wheel specification if the car has replacement wheels, since that affects which available tire products are appropriate within the correct size.
Do all 2010 Lincoln MKS sub-models use the same tire size?
No. The 2010 Lincoln MKS Base spans 235/55R18, 255/45R19, and 245/45R20, while the EcoBoost uses 255/45R19 and 245/45R20. That means tire fitment varies by sub-model and wheel package.
Sub-model name alone may not be enough if the car has different wheels than it left the factory with. A quick check of the current tire sidewall and wheel diameter will narrow the choice immediately, and that is the best way to avoid selecting an 18-inch tire for a 19-inch or 20-inch setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Lincoln MKS?
Start with the correct size for the car’s actual wheel diameter: 235/55R18, 255/45R19, or 245/45R20. From there, compare radial construction details such as rim-width compatibility, load figures where stated, tire weight, sidewall style, and the overall character of the tire series.
The right choice depends on how the MKS is used and how you want it to look. A daily-driven sedan may call for one type of presentation, while a customized car on 20-inch wheels may place more emphasis on sidewall style, so matching the tire to both the wheel and the car’s purpose matters.
What sidewall styles are available for 2010 Lincoln MKS tires?
In the available 245/45R20 fitment for the 2010 Lincoln MKS, sidewall styles include Blackwall, Redline, and RWL, which stands for raised white letter. Those options create noticeably different visual presentations even within the same size.
Sidewall treatment does not change the required size, but it can change the look of the car dramatically. Blackwall keeps a more understated modern appearance, while Redline or raised white letter styling can give a custom or performance-oriented look, so the visual goal should be settled after the fitment is confirmed.
What brands offer tires for the 2010 Lincoln MKS?
Available 245/45R20 tires for the 2010 Lincoln MKS come from BFGoodrich, Nitto, and Pro-Trac. Those choices span several radial series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III.
Brand is only one part of the decision. It still makes sense to compare the exact series, sidewall treatment, and wheel-compatibility details within the correct size, because two tires from different brands may suit very different goals even though both are meant for the same 20-inch MKS fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Lincoln MKS?
A period-style approach for a 2010 Lincoln MKS begins with keeping the correct wheel diameter and tire size already associated with the car, whether that is 235/55R18, 255/45R19, or 245/45R20. Since the MKS is a modern luxury sedan, correct visual proportion matters more than trying to force an older-looking vintage tire style onto it.
Appearance choices become more specific in 245/45R20, where Blackwall, Redline, and raised white letter options are available. Buyers aiming for a clean original-era look should stay close to the car’s factory-era wheel-and-tire proportions, while customized examples can lean more heavily on sidewall style without changing the required fitment.
How does tire construction affect the appearance of a restored 2010 Lincoln MKS?
The 2010 Lincoln MKS uses radial tires, so construction itself is straightforward on this application. The visible effect comes less from bias-ply-versus-radial questions and more from maintaining the correct modern profile, wheel diameter, and sidewall treatment for the look you want.
On a restoration-oriented or well-preserved MKS, the wrong profile or an obviously mismatched wheel package can change the car’s stance quickly. Keeping the proper 18-inch, 19-inch, or 20-inch fitment and choosing a sidewall style that suits the car’s intended presentation will usually matter more than any construction debate.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Lincoln MKS?
Yes. A 2010 Lincoln MKS may use 18-inch, 19-inch, or 20-inch tire fitments, so aftermarket wheels, suspension changes, or body modifications can alter what clears properly. Even when the tire size looks close on paper, wheel width and the actual setup can change the result.
Modified cars should be checked at full steering lock and through suspension travel before settling on a tire. It also helps to confirm the wheel’s true diameter and width rather than relying on trim assumptions, because the MKS already spans several factory-style size combinations before any custom changes are added.
What should I inspect before driving a 2010 Lincoln MKS on new tires?
Check that the new tires match the wheel diameter on the car, seat correctly on the rims, and have even clearance around suspension and body components. It is also smart to inspect valve stems, wheel condition, and overall mounting quality before putting any miles on the car.
A short test drive should be followed by another look for rubbing, unusual vibration, or air loss. Tire pressure should be set correctly for the application, and any signs of alignment trouble, such as immediate uneven wear or steering pull, should be addressed early so the new tires wear evenly.
What should I check before a longer drive in a 2010 Lincoln MKS?
Before a longer drive, inspect tread and sidewalls for cuts, bulges, or cracking, and confirm that all four tires are the correct size for the wheel setup on the car. On a 2010 Lincoln MKS, that is especially important because the model can use 18-inch, 19-inch, or 20-inch fitments.
Pressure, wheel condition, and basic suspension health deserve a look as well, particularly on a car that sits for long periods or has recently received new tires. A quick check for uneven wear and any sign of contact inside the wheelwell can prevent minor fitment or maintenance issues from becoming highway problems.
