The 2014 Lincoln MKS sits in the modern full-size luxury sedan class, blending Lincoln comfort and presence with a more contemporary wheel-and-tire package than earlier collector-era cars. That matters when replacing tires, because this model uses radial fitments in two distinct sizes: 255/45R19 and 245/45R20. The key decision is confirming which wheel diameter is on the car first, especially since the Base model can use either size while the EcoBoost uses 245/45R20. Available choices also vary by brand, series, and sidewall treatment, including blackwall, redline, and raised white letter options. A careful match should balance appearance, wheel compatibility, and the way the car is actually driven.
Which Tire Size Is Right for The 2014 Lincoln MKS
The 2014 Lincoln MKS uses two primary tire sizes, and the first step is confirming the car's wheel diameter. Fitment varies by sub-model and wheel setup, with 255/45R19 used on a 19-inch rim and 245/45R20 used on a 20-inch rim. Once that is confirmed, the decision shifts to selecting the right radial tire style, brand, and sidewall treatment for the way the car is equipped and driven.
245/45R20 is a metric radial size in which 245 identifies the section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 20 is the wheel diameter in inches. On the 2014 Lincoln MKS, this size belongs on a 20-inch wheel and is used on the EcoBoost as well as certain Base configurations. Available selections include BFGoodrich, Nitto, and Pro-Trac options across several series, with blackwall, redline, and RWL sidewall treatments. It is the size to evaluate when the car carries the 20-inch wheel package and the goal is to match both fitment and appearance carefully.
255/45R19 is a metric radial size where 255 indicates nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 19 identifies the wheel diameter in inches. On the 2014 Lincoln MKS, this size is tied to 19-inch wheel fitment rather than the 20-inch setup. Its role is straightforward: it is the correct primary size only for cars equipped with the 19-inch wheel arrangement. Checking the actual wheel on the car matters before ordering, especially on Base models that may appear similar but do not share the same rim diameter.
Sub-model fitment on the 2014 Lincoln MKS is not completely uniform, so identifying the exact version and wheel package matters before choosing a tire. The Base model can use either of the two primary radial sizes, while the EcoBoost uses the 20-inch fitment.

2014 Lincoln MKS Base
The 2014 Lincoln MKS Base has the broadest fitment range, since it can use either the 255/45R19 or the 245/45R20 radial size depending on the wheel setup. Tire selection starts with confirming whether the car has 19-inch or 20-inch wheels, then narrowing the choice by brand, series, and sidewall style.
The 2014 Lincoln MKS EcoBoost uses the 245/45R20 radial fitment, making the wheel diameter decision much more straightforward. Once the 20-inch setup is confirmed, the focus becomes choosing among the available product lines and deciding whether a blackwall, redline, or raised white letter appearance suits the car.
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.

These FAQs focus on the tire sizes used on the 2014 Lincoln MKS, how the Base and EcoBoost fitments differ, and what to compare when choosing radial tires for 19-inch or 20-inch wheels.
Tire Size & Fitment
What tire size fits a 2014 Lincoln MKS?
The 2014 Lincoln MKS uses two primary tire sizes: 255/45R19 and 245/45R20. Both are radial sizes, but they do not serve the same wheel setup. The Base model can use either size depending on how the car is equipped, while the EcoBoost uses 245/45R20.
The practical step is to confirm the wheel diameter on the car before choosing a tire. A 19-inch wheel requires the 255/45R19 fitment, and a 20-inch wheel requires the 245/45R20 fitment. On any MKS with replacement wheels, verify the actual wheel markings rather than assuming the size from trim alone.
What size rim does a 2014 Lincoln MKS use?
A 2014 Lincoln MKS uses either a 19-inch or 20-inch rim, depending on configuration. The 255/45R19 tire belongs with the 19-inch setup, and the 245/45R20 tire belongs with the 20-inch setup. Both are modern radial fitments rather than vintage bias-ply sizes.
Rim diameter should be confirmed first because the two primary tire sizes are not interchangeable across those wheel diameters. It also helps to check wheel width and any aftermarket changes before selecting a tire, especially on a Base model where both factory-style fitments are possible and the visual difference may not be obvious at a glance.
Do all 2014 Lincoln MKS sub-models use the same tire size?
No. The 2014 Lincoln MKS EcoBoost uses 245/45R20, while the Base model can use either 255/45R19 or 245/45R20 depending on the wheel package. That means the exact sub-model helps, but the wheel diameter still has to be confirmed before settling on a tire.
This matters most when buying for a Base car, because two correct primary sizes exist within the same model year and model line. The cleanest approach is to identify the sub-model, then verify whether the car is on 19-inch or 20-inch wheels. That avoids choosing a correct MKS tire size for the wrong wheel.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2014 Lincoln MKS?
Start by confirming that the car actually uses the 20-inch fitment, since 245/45R20 is correct for the EcoBoost and certain Base configurations. From there, compare radial tire options by brand, tire series, sidewall style, and wheel-width compatibility where that specification is given.
The available 245/45R20 choices include BFGoodrich, Nitto, and Pro-Trac products, and they do not all present the car the same way. Blackwall options keep a modern look, while redline and RWL versions add more visual character. Matching the tire to the car's wheel setup and intended appearance usually matters as much as the size itself.
What sidewall styles are available for 2014 Lincoln MKS tires?
For the 245/45R20 fitment used on the 2014 Lincoln MKS, available sidewall styles include blackwall, redline, and RWL. Blackwall appears across several BFGoodrich and Nitto choices, while Pro-Trac Street Pro III is available with either a redline or raised white letter presentation.
Sidewall style changes the look of the car more than the fitment itself, so appearance should be part of the decision once the correct size is confirmed. A blackwall keeps the MKS closer to a contemporary luxury-sedan look, while redline or RWL adds a more customized visual treatment without changing the tire's basic sizing format.
What brands offer tires for the 2014 Lincoln MKS?
The available 245/45R20 tires for the 2014 Lincoln MKS come from BFGoodrich, Nitto, and Pro-Trac. Those options span several radial 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 is only one part of the decision. It helps to compare the exact series, sidewall style, and wheel-width suitability for the specific tire you are considering, especially if the car has a particular appearance goal. Keeping the choice centered on the correct 20-inch fitment is more important than selecting by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Lincoln MKS?
A period-style choice for a 2014 Lincoln MKS starts with using the correct primary size for the car's wheel diameter, then selecting a sidewall treatment that matches the intended presentation. On the 245/45R20 fitment, blackwall gives the most contemporary look, while redline and RWL options create a more customized appearance.
Because this is a modern Lincoln rather than a vintage restoration platform, appearance choices are usually more about style than strict originality. Buyers who want the car to reflect a particular showroom-era look should compare period photos, brochures, or marque-specific references before treating any sidewall treatment as historically exact for their individual car.
How does tire construction affect the appearance of a restored 2014 Lincoln MKS?
On the 2014 Lincoln MKS, tire construction is straightforward because the primary fitments are radial. That means the appearance difference is shaped less by bias-ply versus radial questions and more by sidewall presentation, brand styling, and the visual proportion created by the correct 19-inch or 20-inch wheel setup.
For a clean restoration-oriented result, keeping the correct size on the correct rim matters more than chasing a different construction type. A properly matched radial in the right fitment preserves the car's intended stance, while the choice between blackwall, redline, or RWL lets the owner fine-tune how subtle or expressive the finished car looks.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Lincoln MKS?
Yes. Any 2014 Lincoln MKS with aftermarket wheels, suspension changes, or altered ride height can change what actually fits, even if the car began with a factory-style 255/45R19 or 245/45R20 setup. Wheel diameter, width, and offset all influence clearance at the fender, suspension, and steering components.
A modified MKS should be checked directly before replacing tires. Confirm the actual wheel size on the car, then inspect clearance at full steering lock and through suspension travel. That is especially important on Base models, where two primary factory-style sizes already exist and aftermarket changes can make an otherwise correct OE-size assumption less reliable.
What should I inspect before driving a 2014 Lincoln MKS on new tires?
Before putting a 2014 Lincoln MKS back into regular road use on new tires, inspect wheel condition, valve stems, tread seating, and air pressure, and make sure the tires match the car's actual 19-inch or 20-inch wheel setup. It is also smart to look over alignment wear patterns and basic suspension condition.
A fresh tire cannot compensate for bent wheels, worn steering parts, or poor alignment. After installation, check for any rubbing during turns and over bumps, especially if the car has non-stock wheels or suspension changes. A short road test followed by a pressure recheck helps confirm that the new tires are settling in properly.
How often should tires on a 2014 Lincoln MKS be inspected?
Tires on a 2014 Lincoln MKS should be inspected regularly, with a quick visual check before longer drives and a closer inspection at routine service intervals. Look for uneven wear, cuts, sidewall damage, bulges, embedded debris, and slow pressure loss, whether the car uses 255/45R19 or 245/45R20 tires.
Cars that are driven infrequently still need tire attention, because age and storage conditions can matter as much as mileage. Pressure should be monitored consistently, and any sign of vibration, pulling, or rubbing deserves prompt inspection. Keeping the tires clean, properly inflated, and protected from prolonged outdoor exposure helps preserve both safety and ride quality.
