The 2015 Lincoln MKZ sits in the modern luxury-sedan space where sleek styling, quiet road manners, and contemporary wheel packages all shape the tire decision. Its design moved the MKZ firmly into a more sculpted, upscale direction, so tire choice affects both appearance and how the car feels on the road. This model uses two primary radial tire sizes, 245/40R19 and 245/45R18, depending on sub-model and wheel setup. That keeps the decision centered on confirming the exact configuration first, then comparing available blackwall performance-oriented radial choices by brand and series. For owners maintaining factory-style proportions, wheel diameter and overall fitment consistency matter most.
Which Tire Size Is Right for The 2015 Lincoln MKZ
The 2015 Lincoln MKZ uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel diameter. Both fitments are radial, but one uses an 18-inch rim and the other uses a 19-inch rim, so confirming the actual wheel setup is the first step before comparing tire series, brand options, or other specification differences.
Fit(s): Base, Black Label, Black Label Hybrid, and Hybrid
Construction: Radial|Rim: 19 in
245/40R19 is a metric radial size in which 245 designates the section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2015 Lincoln MKZ, this size supports a lower-profile wheel-and-tire package that is used on certain sub-models. Available choices center on blackwall radials from BFGoodrich across g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This size makes sense when the car is already equipped with 19-inch wheels and the goal is to stay with the intended overall stance and fitment type.
245/45R18 is a metric radial size where 245 is the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 18 marks the wheel diameter in inches. For the 2015 Lincoln MKZ, this size is used on 18-inch wheel applications and differs from the 19-inch fitment even though the section width remains the same. Product choices include blackwall radials from BFGoodrich and Nitto, with series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. It is the right size to evaluate only after confirming the car is actually running the 18-inch wheel package.
Sub-model fitment on the 2015 Lincoln MKZ is not completely uniform, because some versions use one tire size while others can use either of the two primary fitments. Checking the exact sub-model helps narrow the correct tire size before comparing 18-inch and 19-inch wheel applications.

2015 Lincoln MKZ Base
The 2015 Lincoln MKZ Base can use either of the model's two primary radial tire sizes, depending on its wheel setup. That makes wheel-diameter confirmation especially important before choosing between the available 18-inch and 19-inch tire options.
The 2015 Lincoln MKZ Black Label uses the 245/40R19 radial fitment. Tire selection here is less about choosing between sizes and more about matching the 19-inch wheel package with the right blackwall tire series and specifications.
The 2015 Lincoln MKZ Black Label Hybrid also uses the 245/40R19 radial tire size. With the size already defined, the practical choice becomes comparing the available 19-inch product options while keeping the car's wheel diameter and intended road use in mind.
The 2015 Lincoln MKZ Hybrid can use either 245/40R19 or 245/45R18, so tire fitment depends on the actual wheels on the car. Before selecting a tire, confirm whether the Hybrid is equipped with the 18-inch or 19-inch setup rather than assuming one size applies to every example.
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 2015 Lincoln MKZ?
A 2015 Lincoln MKZ uses either 245/40R19 or 245/45R18, depending on the specific sub-model and wheel package. Both are radial tire sizes, but they are not interchangeable primary fitments because they are built for different rim diameters.
The first thing to verify is whether the car has 18-inch or 19-inch wheels. Base and Hybrid versions can appear with either size, while Black Label and Black Label Hybrid use 245/40R19, so the safest approach is to confirm the actual wheel setup before selecting a tire.
What size rim does a 2015 Lincoln MKZ use?
The 2015 Lincoln MKZ uses either an 18-inch or 19-inch rim, depending on which of its two primary tire sizes applies. The 245/45R18 fitment uses an 18-inch wheel, and the 245/40R19 fitment uses a 19-inch wheel.
That rim-diameter difference is the key fitment checkpoint on this model. Before comparing tires, confirm the actual wheel diameter on the car rather than relying only on model name, since some MKZ sub-models can use more than one tire size and the wheel must match the tire exactly.
Do all 2015 Lincoln MKZ sub-models use the same tire size?
No, 2015 Lincoln MKZ sub-models do not all use the same tire size. Black Label and Black Label Hybrid use 245/40R19, while Base and Hybrid versions can use either 245/40R19 or 245/45R18 depending on wheel configuration.
That means the sub-model name helps narrow the choices, but it does not always finish the job by itself. On Base and Hybrid cars especially, checking the installed wheel diameter is still necessary, since the final tire decision depends on whether the car is equipped with the 18-inch or 19-inch setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Lincoln MKZ?
Start with the correct primary size, because the 2015 Lincoln MKZ uses either 245/40R19 or 245/45R18. After size and wheel diameter are confirmed, the next considerations are tire series, brand, load specification where stated, and whether the car is being used more for everyday driving or a more performance-oriented feel.
The available assortment is entirely radial and centers on blackwall designs, so much of the choice comes down to matching the tire to the car's actual wheel package and intended use. Comparing rim-width compatibility is also worthwhile, especially if the car has replacement wheels rather than its original wheel setup.
What brands offer tires for the 2015 Lincoln MKZ?
Tires for the 2015 Lincoln MKZ are available from BFGoodrich and Nitto in the sizes used on this model. BFGoodrich appears in both 245/40R19 and 245/45R18, while Nitto is available in the 245/45R18 fitment.
Brand choice should still come after fitment confirmation. Once the correct size is established, compare the available series within that size along with rim-width specifications and any stated load details, since the strongest buying decision on the MKZ is usually not the brand alone but the complete tire-and-wheel match.
What tire series are available for the 2015 Lincoln MKZ?
The 2015 Lincoln MKZ has several available tire series across its two primary sizes, including BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2. Not every series appears in both sizes, so the exact fitment still determines which options are open.
Series differences matter because they shape the comparison within the correct size rather than changing the fitment itself. Once the 18-inch or 19-inch setup is confirmed, the buyer can focus on which series best suits the car's role, while still checking wheel width compatibility and any other stated product specifications.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Lincoln MKZ?
A period-style approach on a 2015 Lincoln MKZ starts with keeping the correct modern radial size for the car's actual wheel package, either 245/40R19 or 245/45R18. Since the available tires for this application are blackwall radials, the appearance remains consistent with the MKZ's contemporary luxury-sedan presentation.
The better question on this model is usually whether to preserve the original wheel-and-tire proportion rather than chase a vintage look. Staying with the proper rim diameter and overall size family helps maintain the car's intended stance, while changes in wheel design or tire profile can alter the visual balance noticeably.
Does correct tire fitment matter for a 2015 Lincoln MKZ restoration?
Yes, correct tire fitment matters on a 2015 Lincoln MKZ restoration because wheel diameter and tire profile are part of the car's overall appearance as well as its road behavior. Using 245/40R19 on a 19-inch setup or 245/45R18 on an 18-inch setup keeps the visual proportions aligned with the intended configuration.
Restoration-minded owners should also look closely at the actual wheels on the car, especially if it has changed hands or been modified. A replacement wheel package can shift the required tire size, so confirming the rim diameter and width before purchase is just as important as selecting the correct brand or tire series.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Lincoln MKZ?
Yes, modifications can affect tire fitment on a 2015 Lincoln MKZ, especially when they involve wheel diameter, wheel width, offset, ride height, or suspension changes. The car's original fitments are 245/40R19 and 245/45R18, so any departure from the original wheel setup can change what works safely and cleanly.
Even when the tire size looks close on paper, clearance at the fender, suspension, and steering points still needs to be checked. A modified MKZ should be measured as it sits, because aftermarket wheels or altered suspension geometry can create fitment issues that do not exist on a standard car.
What should I inspect before driving a 2015 Lincoln MKZ on new tires?
Before driving a 2015 Lincoln MKZ on new tires, confirm that the tire size matches the car's wheel diameter and that the wheels are in sound condition. It also makes sense to check inflation, valve stems, and overall mounting quality before putting the car into regular road use.
A quick inspection after installation helps catch issues early. Look for rubbing at full steering lock, verify that the tires clear suspension and body components, and keep an eye on air loss or unusual wear during the first few drives, especially if the car has replacement wheels or suspension changes.
How often should tires on a 2015 Lincoln MKZ be inspected?
Tires on a 2015 Lincoln MKZ should be inspected regularly, not just when tread appears low. A routine visual check for uneven wear, cuts, punctures, sidewall damage, and air-pressure loss helps catch problems early whether the car is driven daily or stored for longer periods.
Collector-style low mileage does not eliminate tire concerns, because age and storage conditions still matter. Checking the tires before longer trips is a good habit, and a closer inspection is especially worthwhile if the MKZ has sat for extended periods or has seen wheel, alignment, or suspension work.
