The 2015 Lincoln MKS sits in the last stretch of Lincoln’s full-size sedan era, blending modern luxury-car proportions with available performance in a way that still appeals to owners who want comfort without giving up presence. Tire selection on this car starts with identifying the exact setup, because the MKS uses either 245/45R20 or 255/45R19 radial tires depending on configuration. That means the first decision is wheel diameter, followed by the look and character of the tire itself. In 245/45R20, choices include blackwall, redline, and raised white letter styling across several series. For a clean replacement, the best approach is matching the car’s actual wheel package and intended use before comparing appearance and performance.
Which Tire Size Is Right for The 2015 Lincoln MKS
Two primary tire sizes apply to the 2015 Lincoln MKS, and the difference is tied to configuration and wheel diameter. Some MKS models use 245/45R20 on a 20-inch rim, while others use 255/45R19 on a 19-inch rim, so the first step is confirming the exact sub-model and the wheels currently on the car. Once that is settled, the decision becomes choosing the right radial tire style, series, and specifications within the correct size.
255/45R19 is a modern metric radial size where 255 is the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2015 Lincoln MKS, this size applies to certain Base configurations that use a 19-inch wheel rather than the 20-inch setup. Its role within the MKS range is to distinguish a different wheel-and-tire package, not simply a styling variation within the same rim diameter. It should be evaluated only after confirming that the car retains the proper 19-inch wheel arrangement.
Sub-model fitment matters on the 2015 Lincoln MKS because tire size is not the same across every configuration. The Base model can use either of the two primary sizes, while the EcoBoost uses the 20-inch radial setup, so checking the exact sub-model and wheel package should come before selecting tires.

2015 Lincoln MKS Base
The 2015 Lincoln MKS Base can use either the 245/45R20 or 255/45R19 radial size, depending on the wheel package on the car. Tire selection starts with confirming whether the car has 19-inch or 20-inch wheels, then comparing the available product styles and specifications within that correct size.
The 2015 Lincoln MKS EcoBoost uses the 245/45R20 radial size on a 20-inch wheel. That makes the choice more straightforward, with attention shifting from size identification to the preferred tire series, sidewall appearance, and wheel compatibility within the 20-inch fitment.
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.

The most important questions for the 2015 Lincoln MKS center on identifying the correct 19-inch or 20-inch tire size, understanding sub-model differences, and comparing available radial tire styles, brands, and road-use considerations.
Tire Size & Fitment
What tire size fits a 2015 Lincoln MKS?
The 2015 Lincoln MKS uses two primary tire sizes: 245/45R20 and 255/45R19. Both are radial sizes, and the correct one depends on the specific configuration and wheel package on the car rather than a one-size-fits-all fitment across the entire model line.
The practical first step is checking whether the car has 19-inch or 20-inch wheels, then confirming the sub-model. A Base model may appear with either size, while the EcoBoost uses 245/45R20. If the car has changed hands or has aftermarket wheels, verify the actual wheel setup before choosing a replacement tire.
What size rim does a 2015 Lincoln MKS use?
A 2015 Lincoln MKS uses either a 20-inch rim with 245/45R20 tires or a 19-inch rim with 255/45R19 tires. The rim diameter is built into the tire size itself, so the last number in each size is the wheel diameter the tire is intended to mount on.
That matters because a 19-inch tire cannot be mounted on a 20-inch wheel, and a 20-inch tire cannot be mounted on a 19-inch wheel. Before buying tires, confirm the actual wheel diameter on the car and check that the wheel width also suits the tire being considered, especially if the MKS has been modified.
Do all 2015 Lincoln MKS sub-models use the same tire size?
No. The 2015 Lincoln MKS does not use one tire size across every sub-model. The EcoBoost uses 245/45R20, while the Base model can use either 245/45R20 or 255/45R19 depending on the wheel package fitted to that particular car.
That means identifying the sub-model helps, but wheel confirmation is still essential on a Base sedan. A quick visual check of the tire sidewall or wheel diameter will settle the question. Once the correct size is confirmed, the next step is comparing radial tire options by brand, series, sidewall style, and wheel compatibility.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2015 Lincoln MKS?
Start with the basics: correct size, radial construction, and compatibility with the car’s 20-inch wheel. For the 2015 Lincoln MKS, 245/45R20 choices vary by brand, tire series, sidewall appearance, and in some cases rim-width guidance and load specification, so the right pick depends on how the car is used and how the owner wants it to look.
A blackwall tire keeps the presentation contemporary, while redline or raised white letter styling creates a stronger visual statement. It also helps to compare wheel-width suitability where stated and to make sure the car still has the intended 20-inch setup. Matching the tire to both the wheel and the MKS’s role as a road car matters more than choosing by appearance alone.
What sidewall styles are available for 2015 Lincoln MKS tires?
In 245/45R20, the 2015 Lincoln MKS has sidewall choices that include blackwall, redline, and RWL, or raised white letter. That creates a useful spread between a subdued modern look and more expressive styling that stands out on the car.
Sidewall style does not change the need to match the correct size and wheel diameter, but it does shape the car’s overall presentation. Blackwall generally suits a cleaner late-model appearance, while redline and raised white letters add a custom or performance-oriented visual cue. The best choice depends on whether the MKS is being kept understated or given a more individualized look.
What brands offer tires for the 2015 Lincoln MKS?
The 245/45R20 fitment for the 2015 Lincoln MKS is available from BFGoodrich, Nitto, and Pro-Trac. 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 selection should be treated as one part of the decision rather than the whole decision. It still makes sense to compare the exact series, sidewall style, and wheel-width suitability where that information is stated. Keeping the correct 245/45R20 size at the center of the process will usually narrow the choices faster than focusing on brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Lincoln MKS?
A period-style approach on a 2015 Lincoln MKS still starts with the correct modern radial size for the car’s wheel package, either 245/45R20 or 255/45R19. From there, the visual direction depends on whether the goal is a restrained luxury-sedan look or a more assertive custom presentation.
Within 245/45R20, blackwall keeps the appearance closest to a typical contemporary luxury fitment, while redline or raised white letter styling adds a more deliberate enthusiast touch. Since exact originality can matter to some owners, it helps to compare the car with period sales material, photos, or marque-specific references before choosing a more dramatic sidewall treatment.
How does tire construction affect the appearance of a restored 2015 Lincoln MKS?
On the 2015 Lincoln MKS, the primary fitments are radial tires, so construction itself does not create a bias-ply-versus-radial appearance decision. The more visible styling difference comes from sidewall treatment and tire series, especially in the 245/45R20 size where multiple looks are available.
That means appearance planning should focus on how the tire complements the car’s wheels, stance, and intended character. A blackwall presentation reads closer to a standard late-model luxury sedan, while redline or raised white letter options shift the look toward custom or performance-inspired territory. Keeping the correct size in place preserves the MKS’s visual proportions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Lincoln MKS?
Yes. Modifications can affect tire fitment on a 2015 Lincoln MKS even when the tire size itself looks close to stock. Aftermarket wheels, different wheel widths, offset changes, lowering, or suspension alterations can all change how a 245/45R20 or 255/45R19 tire sits within the wheel opening and steering range.
That is why the tire sidewall size alone should not be treated as the full answer on a modified car. Check wheel diameter, wheel width, and clearance at full steering lock and through suspension travel before replacing tires. Any MKS with non-stock wheels deserves a fresh fitment check instead of assuming the previous setup is automatically correct.
What should I inspect before driving a 2015 Lincoln MKS on new tires?
Before putting a 2015 Lincoln MKS into regular road use on new tires, inspect basic installation and vehicle-condition points. Check that the tires match the intended size, the wheels are the correct diameter, inflation is set properly, and there are no visible issues such as rubbing, uneven seating, or interference with suspension or body components.
A quick road-use check should also include wheel fastener torque, steering feel, and any signs of vibration once the car is moving. It helps to recheck tire pressure after the first driving cycle and to confirm clearance again if the car has aftermarket wheels. Catching those details early is especially important on a heavy full-size sedan like the MKS.
How often should tires on a 2015 Lincoln MKS be inspected?
Tires on a 2015 Lincoln MKS should be inspected regularly, not just when tread looks low. A visual check for uneven wear, cuts, cracking, bulges, and air loss is a good routine habit, especially on a car that may alternate between daily use and longer periods of sitting.
Monthly pressure checks are a sensible baseline, and a closer inspection before highway travel is worthwhile. It also helps to pay attention to changes in ride quality, pull, or vibration, since those can point to inflation, alignment, or tire-condition issues. On a car with 19-inch or 20-inch wheels, small problems can become noticeable quickly if left unattended.
