The 2020 Lincoln MKZ sits at the end of Lincoln’s midsize sedan line, blending contemporary luxury-sedan styling with a more driver-focused character than many buyers expect. It appeals to owners who want a modern Lincoln that still feels distinctive on the road. Tire selection on the 2020 Lincoln MKZ centers on two primary radial sizes, 245/45R18 and 245/40R19, and the first step is confirming which wheel diameter your car uses. Available choices lean toward performance-oriented blackwall radials from BFGoodrich and Nitto, with differences in tire series and rim-width compatibility. That makes the decision less about vintage-style construction and more about matching the correct size to your exact MKZ setup and intended road use.
Which Tire Size Is Right for The 2020 Lincoln MKZ
The 2020 Lincoln MKZ uses two primary tire sizes, and the right one depends first on wheel diameter and then on sub-model or wheel package. Both are radial metric sizes, but one fits an 18-inch rim and the other fits a 19-inch rim. Before choosing a tire, confirm whether your MKZ is on 18-inch or 19-inch wheels, especially if the car has been changed from its original wheel setup.
Fit(s): Base, Hybrid, Reserve 2.0T, Reserve 3.0T, and Reserve Hybrid
Construction: Radial|Rim: 19 in
A 245/40R19 tire uses a 245-millimeter section width, a 40-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2020 Lincoln MKZ, this size supports a lower-profile modern fitment and appears across several sub-models, including the Reserve 2.0T, Reserve 3.0T, and Reserve Hybrid. Available choices include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, all in blackwall form. This size is the one to evaluate when your MKZ already has 19-inch wheels and you want to compare tire series within that exact fitment.
A 245/45R18 tire keeps the same 245-millimeter nominal width but uses a taller 45-series sidewall on an 18-inch rim. For the 2020 Lincoln MKZ, this is a primary radial fitment that applies to Base and Hybrid configurations equipped with 18-inch wheels. Product choices include blackwall offerings from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is the correct starting point when your MKZ is on 18-inch wheels and you want to compare brands, series character, and wheel-width compatibility.
Tire fitment on the 2020 Lincoln MKZ varies by sub-model and wheel setup, so identifying the exact version of the car matters before selecting a tire. Some sub-models use only the 19-inch fitment, while others may be found with either 18-inch or 19-inch radial sizes.

2020 Lincoln MKZ Base
The 2020 Lincoln MKZ Base can use either of the two primary radial sizes, depending on whether the car is equipped with 18-inch or 19-inch wheels. That makes wheel confirmation especially important before comparing tire series, since both fitments are valid within this sub-model.
The 2020 Lincoln MKZ Hybrid also appears with both primary radial tire sizes, tied to either an 18-inch or 19-inch wheel setup. Tire selection starts with the actual wheel on the car, then shifts to comparing available brands and series within the correct size.
The 2020 Lincoln MKZ Reserve 2.0T uses the 245/40R19 radial size on a 19-inch rim. With fitment narrowed to one primary size, the main decision becomes choosing among the available blackwall performance-oriented tire series that suit your driving priorities.
The 2020 Lincoln MKZ Reserve 3.0T uses the 245/40R19 radial fitment. Since the size itself is straightforward here, attention can shift to selecting the right tire series and confirming wheel width remains compatible if the car has aftermarket wheels.
The 2020 Lincoln MKZ Reserve Hybrid uses the 245/40R19 radial size. Tire choice for this sub-model is mainly about staying with the correct 19-inch fitment and then comparing available blackwall tire options within that same size.
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 2020 Lincoln MKZ?
The 2020 Lincoln MKZ uses two primary tire sizes: 245/45R18 and 245/40R19. Both are radial metric sizes, and the correct one depends on the wheel diameter and the exact sub-model or wheel package on the car. Base and Hybrid versions may use either size, while Reserve 2.0T, Reserve 3.0T, and Reserve Hybrid use 245/40R19.
The practical first step is to confirm whether the car has 18-inch or 19-inch wheels before choosing a tire. On a modern sedan like the MKZ, many cars stay original, but aftermarket wheels or replacement wheel sets can change what is actually on the vehicle. Matching the tire to the actual rim diameter is more important than assuming every MKZ uses the same fitment.
What size rim does a 2020 Lincoln MKZ use?
A 2020 Lincoln MKZ uses either an 18-inch or 19-inch rim, depending on the tire size fitted to the car. The 245/45R18 size uses an 18-inch rim, and the 245/40R19 size uses a 19-inch rim. Both sizes have very similar overall diameter, but they are built for different wheel diameters.
Rim diameter should be confirmed at the wheel before selecting tires, especially on a car that may have had wheel changes over time. Tire sidewall markings and wheel measurements can verify what is installed now. Even when two tire sizes are close in overall dimensions, a tire for an 18-inch rim cannot be mounted on a 19-inch wheel, or the other way around.
Do all 2020 Lincoln MKZ sub-models use the same tire size?
No, not every 2020 Lincoln MKZ sub-model uses the same tire size. Base and Hybrid versions can use either 245/45R18 or 245/40R19, while Reserve 2.0T, Reserve 3.0T, and Reserve Hybrid use 245/40R19. That means the correct fitment depends on both the sub-model and the wheel diameter actually on the vehicle.
This matters because tire selection for an MKZ is not just a matter of model year and nameplate. A Base or Hybrid sedan may be equipped with either wheel size, so checking the tire sidewall or measuring the wheel is the safest way to avoid ordering the wrong fitment. Once the size is confirmed, comparison becomes much more straightforward within that exact tire category.
Choosing the Right Tire
What should I consider when choosing a 2020 Lincoln MKZ tire?
Start with the correct primary size for the car: 245/45R18 on an 18-inch wheel or 245/40R19 on a 19-inch wheel. From there, compare radial tire series, brand, rim-width compatibility, and any useful specification differences such as load capacity or tire weight. The available 2020 Lincoln MKZ choices are all blackwall radials, so the main decision is fitment and product character rather than sidewall style.
It helps to think about how the MKZ is actually used. A daily-driven sedan, a fair-weather commuter, and a car with aftermarket wheels may point you toward different priorities within the same size. Confirm the wheel width falls within the tire’s approved range, and make sure the selected tire matches the car’s current setup instead of relying only on model-year assumptions.
What brands offer tires for the 2020 Lincoln MKZ?
The 2020 Lincoln MKZ tire sizes here are available from BFGoodrich and Nitto. BFGoodrich appears in both 245/40R19 and 245/45R18 with several g-Force series choices, while Nitto appears in 245/45R18 with the NT555 G2. All of these are radial blackwall tires sized for modern wheel fitments.
Brand choice is only one part of the decision. It is more useful to compare the exact tire series within the correct size, along with wheel-width compatibility and any load specification that matters to your setup. Staying within the proper 18-inch or 19-inch fitment matters more than choosing a brand name first and then trying to make it fit the wrong wheel.
What tire series are available for the 2020 Lincoln MKZ?
Available tire series for the 2020 Lincoln MKZ include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, plus the Nitto NT555 G2 in 245/45R18. Those series give buyers several radial choices within the correct MKZ sizes rather than limiting the car to a single replacement pattern.
Comparing series can help narrow the right tire once size is settled, especially if more than one option fits your wheel diameter. A useful next step is checking the approved rim-width range and any load figure attached to a given tire, then matching that to how the car is equipped and driven. That approach keeps the decision practical instead of relying on name recognition alone.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Lincoln MKZ restoration?
Yes, correct tire fitment still matters on a 2020 Lincoln MKZ, even though the car is much newer than a traditional collector vehicle. The right size preserves the intended relationship between wheel diameter, sidewall profile, and overall stance. For this MKZ, that means using either 245/45R18 or 245/40R19 according to the actual wheel setup and sub-model.
Appearance on a later luxury sedan is usually about maintaining the proper proportions rather than recreating a vintage sidewall treatment. Staying with the correct metric radial size keeps the car looking settled and avoids visual mismatches between tire and wheel. If originality is especially important, verify the existing wheel and tire package against vehicle-specific references before replacing anything.
How does tire construction affect the appearance of a restored 2020 Lincoln MKZ?
Tire construction affects the appearance of a 2020 Lincoln MKZ mainly through the modern radial shape and profile that the car was designed around. Both primary MKZ fitments are radial metric sizes, and the available products are blackwall radials. That means the visual differences come more from the wheel-and-sidewall proportion than from a choice between vintage constructions.
For a clean, restoration-minded presentation, the important thing is using the proper size for the wheel on the car and avoiding substitutions that alter the profile too much. A 245/45R18 and a 245/40R19 can both suit the MKZ, but each belongs with its own rim diameter. Keeping that relationship correct helps the car retain its intended modern luxury-sedan look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Lincoln MKZ?
Yes, modifications can affect tire fitment on a 2020 Lincoln MKZ. Wheel diameter, wheel width, offset changes, suspension lowering, or other chassis changes can all alter whether a 245/45R18 or 245/40R19 tire remains appropriate for the car. Even when the nominal tire size looks correct, the total setup may not behave the same once those changes are made.
A modified MKZ should be checked for actual wheel size, wheel-width compatibility, and clearance at steering and suspension travel before replacement tires are chosen. That is especially important when buying tires by model name alone. Looking at the car’s present configuration first helps avoid rubbing, wheel mismatch, or selecting a tire that suits the catalog size but not the vehicle as equipped.
What should I inspect before driving a 2020 Lincoln MKZ on new tires?
Before driving a 2020 Lincoln MKZ on new tires, inspect the wheel diameter and width, verify the tire size matches the car, and confirm inflation is set correctly for the installed tires and vehicle application. It is also wise to look over the valve stems, lug torque, and the general condition of the wheels before putting the car back into regular road use.
A short follow-up check after the first drive can catch issues early. Watch for vibration, rubbing, uneven clearance, or steering feel that seems unusual, especially if the car has different wheels than it left the factory with. On an MKZ with 18-inch or 19-inch fitments, a careful first inspection helps confirm the tires are working with the whole wheel and suspension package.
How often should tires on a 2020 Lincoln MKZ be inspected?
Tires on a 2020 Lincoln MKZ should be inspected regularly, not just when replacement time arrives. A quick visual check for air loss, irregular wear, cuts, bulges, and sidewall damage is smart before longer drives, and periodic close inspection is important even on cars that are driven less often. Modern radial tires still age, even when tread wear is limited.
Low-use luxury sedans can develop tire issues that are easy to miss because the car spends more time parked than driven. Check pressures consistently, keep the tires clean, and look for signs that storage conditions may be accelerating aging. Catching problems early is especially useful on a vehicle with size-specific 18-inch or 19-inch fitments, since replacing one mismatched tire can complicate the setup.
