The 2012 Lincoln MKS sits in the modern full-size luxury sedan category, blending Lincoln comfort with a more contemporary performance and technology focus than many earlier American cruisers. Tire choice on this car is more configuration-sensitive than on many vintage applications, because the MKS uses three primary radial sizes: 235/55R18, 255/45R19, and 245/45R20. That means the first step is confirming which wheel package is on the car. Within the available 245/45R20 fitment, there is also meaningful choice in brand, tire series, and sidewall presentation, including blackwall, redline, and raised white letter styling. For any 2012 Lincoln MKS, the right tire decision starts with exact wheel diameter, then balances appearance, use, and overall fitment.
Which Tire Size Is Right for The 2012 Lincoln MKS
The 2012 Lincoln MKS uses three primary tire sizes, and they do not all apply across every configuration. The most important first step is confirming the car's wheel diameter, because this MKS can be fitted with 18-inch, 19-inch, or 20-inch rims. Once that is settled, the real decision becomes choosing the correct radial size for the car's setup and then comparing available tire styles and product differences within that fitment.
235/55R18 is a metric radial size in which 235 identifies section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On a 2012 Lincoln MKS, this size belongs to the 18-inch wheel fitment and keeps the selection focused on a modern radial tire format rather than a vintage numeric or alphanumeric system. Its role in the MKS range is straightforward: it is the size to evaluate when the car is equipped with 18-inch wheels. Before choosing a tire, confirm the actual wheel diameter on the car, especially if wheels have been changed since new.
245/45R20 is a metric radial size that uses a 245-millimeter section width, a 45-series profile, and a 20-inch rim diameter. For the 2012 Lincoln MKS, this is one of the larger-wheel primary fitments and it carries the broadest visible product variety, including BFGoodrich, Nitto, and Pro-Trac choices. 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, Nitto NT555 G2, and Street Pro III. This size deserves extra attention from buyers who want to balance wheel-package accuracy with performance-oriented styling and sidewall appearance.
255/45R19 is a metric radial size with a 255-millimeter section width, a 45-series aspect ratio, and a 19-inch rim diameter. On the 2012 Lincoln MKS, it represents the 19-inch wheel fitment and serves as a separate primary size from the 18-inch and 20-inch setups rather than an interchangeable substitute. Its place in the MKS fitment range makes wheel confirmation especially important before comparing tires. Buyers considering this size should verify that the car still has its 19-inch wheels and check for any suspension or wheel changes that could affect clearance or overall selection.
Sub-model fitment matters on the 2012 Lincoln MKS because tire size is not completely uniform across the range. The Base model can use three different radial sizes, while the EcoBoost uses two, so identifying the exact sub-model and wheel package comes before choosing a tire.

2012 Lincoln MKS Base
The 2012 Lincoln MKS Base has the broadest fitment spread, covering 18-inch, 19-inch, and 20-inch radial tire setups. That makes wheel confirmation especially important, and once the correct size is established, the decision shifts to comparing product style, brand, and sidewall presentation within that fitment.
The 2012 Lincoln MKS EcoBoost uses the 19-inch and 20-inch radial fitments rather than the full three-size spread seen on the Base model. Tire selection starts with confirming which of those wheel diameters is actually on the car, then narrowing the choice by tire style and intended road 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 2012 Lincoln MKS?
The 2012 Lincoln MKS uses three primary radial tire sizes: 235/55R18, 255/45R19, and 245/45R20. The Base model can use all three sizes, while the EcoBoost uses 255/45R19 and 245/45R20. Those sizes are tied to different wheel diameters, so they are separate fitments rather than one interchangeable group.
The most important next step is checking the actual wheels on the car before selecting a tire. An MKS with 18-inch wheels needs a different size than one with 19-inch or 20-inch wheels, and aftermarket wheel changes can complicate the picture further. Start by matching the tire size to the wheel diameter already on the car.
What size rim does a 2012 Lincoln MKS use?
The 2012 Lincoln MKS uses three rim diameters depending on configuration: 18-inch, 19-inch, and 20-inch. Those rim sizes correspond to the vehicle's three primary tire fitments, which are 235/55R18, 255/45R19, and 245/45R20. The EcoBoost uses the 19-inch and 20-inch setups, while the Base model covers all three.
Rim diameter should be confirmed before anything else because the tire size is built around it. A 20-inch tire cannot be mounted on a 19-inch wheel, and the same goes for the other combinations. Check the sidewall on the current tire or measure the wheel directly if there is any doubt about what is on the car now.
Do all 2012 Lincoln MKS sub-models use the same tire size?
No, the 2012 Lincoln MKS does not use one universal tire size across all covered sub-models. The Base model can use 235/55R18, 255/45R19, or 245/45R20, while the EcoBoost uses 255/45R19 or 245/45R20. That means sub-model and wheel package both matter when narrowing down the correct fitment.
This is one of those vehicles where assuming all MKS models use the same tire can lead to the wrong purchase. Checking the exact sub-model helps, but wheel diameter still needs to be verified on the car itself, especially if the vehicle has changed hands or received replacement wheels. Size selection comes before comparing brands or sidewall style.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2012 Lincoln MKS?
Start with the basics: the tire must be 245/45R20 and the car must have 20-inch wheels. Within that size, choices vary by brand, tire series, sidewall treatment, and some product specifications such as rim-width range and load information. Available examples include BFGoodrich, Nitto, and Pro-Trac radial options.
The better choice depends on how the car is used and how you want it to look. Some owners may want a straightforward blackwall presentation, while others may prefer redline or raised white letter styling. It also helps to compare the wheel's actual width against the tire's rim-width specification before settling on one product.
What sidewall styles are available for 2012 Lincoln MKS tires?
Within the available 245/45R20 fitment for the 2012 Lincoln MKS, sidewall choices include Blackwall, Redline, and RWL. Blackwall offers the most understated modern appearance, while Redline and RWL add a more assertive visual statement. All of these remain radial tires in the same basic size category.
Sidewall choice affects appearance more than basic fitment, but it can make a noticeable difference in how the car presents. A blackwall tire tends to suit a cleaner contemporary look, while redline or raised white letters bring more visual contrast. Once the correct size is confirmed, sidewall style becomes a useful way to tailor the MKS to your taste.
What brands offer tires for the 2012 Lincoln MKS?
For the 245/45R20 fitment used on the 2012 Lincoln MKS, available brands include BFGoodrich, Nitto, and Pro-Trac. Those choices cover several tire series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III. Each remains within the radial construction used on this vehicle.
Brand alone should not be the only deciding factor. It makes more sense to compare the exact tire series, sidewall appearance, and wheel-width compatibility that match your car's setup and the look you want. Once the size and rim diameter are confirmed, those details usually do more to narrow the field than the brand name by itself.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Lincoln MKS?
A period-style approach on a 2012 Lincoln MKS starts with keeping the correct primary tire size for the wheel package already on the car. Because this is a modern radial application, the most useful appearance decisions happen within the correct size rather than through a shift to vintage-style sizing. For 245/45R20, that means comparing available radial series and sidewall treatments.
The visual character of the car can change noticeably with the tire you choose, especially in 20-inch fitment where blackwall, redline, and RWL options exist. Buyers trying to preserve a clean, era-appropriate presentation should confirm the original wheel diameter on the car first, then choose the sidewall style that best supports that appearance goal.
How does tire construction affect the appearance of a restored 2012 Lincoln MKS?
On a 2012 Lincoln MKS, tire construction is straightforward because the primary fitments are radial. That means appearance differences are shaped less by bias-ply versus radial concerns and more by the exact tire size, sidewall style, and tread-family presentation within the correct radial fitment. In the available 245/45R20 range, those cosmetic choices are easy to see.
A blackwall tire keeps the look restrained and contemporary, while redline or raised white letters add more contrast and visual energy. For a restoration-minded owner, staying with the correct wheel diameter and matching the overall character of the car matters more than chasing a radically different tire style. Appearance starts with fitment discipline, then sidewall choice refines the result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Lincoln MKS?
Yes, modifications can affect tire fitment on a 2012 Lincoln MKS even when the tire size looks close on paper. Aftermarket wheels, suspension changes, altered ride height, and body or brake modifications can all influence clearance and compatibility. That matters even more on a vehicle that already uses multiple factory wheel diameters.
A modified MKS should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and suspension movement before a tire is chosen. Cars with changed wheels may also depart from the original size range entirely. Measuring the setup on the car is the safest way to avoid rubbing, mounting issues, or an unintended change in stance.
What should I inspect before driving a 2012 Lincoln MKS on new tires?
Before putting a 2012 Lincoln MKS back on the road with new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure each tire is properly seated and inflated. It also helps to check for any obvious suspension or alignment issues that could shorten tire life or affect how the car tracks.
Road-use confidence comes from checking the whole setup rather than the tires alone. Look over the tires for cuts, bulges, or air loss after installation, and make sure nothing contacts the inner fender or suspension during turning. A short local drive followed by a second inspection is a sensible way to confirm the installation behaves as expected.
How often should tires on a 2012 Lincoln MKS be inspected?
Tires on a 2012 Lincoln MKS should be inspected regularly rather than waiting for a visible problem. Check pressure, tread condition, and the sidewalls for cracking, cuts, or bulges, especially if the car sits for extended periods or is driven only occasionally. Low-use vehicles can still develop age-related issues even when tread depth appears acceptable.
Frequent visual checks are especially useful on a vehicle with multiple possible wheel and tire setups, because replacement history may not always be obvious. It is also smart to inspect before longer drives and after seasonal storage. Catching air loss, uneven wear, or sidewall damage early helps protect both ride quality and overall fitment confidence.
